< Back to Issue 5 Why Do We Gossip? Lily McCann 24 October 2023 Edited by Celina Kumala Illustrated by Rachel Ko Have you ever heard of ‘Scold’s bridle’? A metal restraint, fitted with a gag, that was strapped about the face as a medieval punishment for excessive chatter; gossip, it seems, was not received too fondly in the Middle Ages. While the bridle may have gone out of fashion long ago, today the word gossip still carries negative connotations. The Oxford Dictionary, for instance, defines gossip as “informal talk or stories about other people’s private lives, that may be unkind or not true” (Oxford Learner’s Dictionaries, 2023). Entries in the Urban Dictionary use yet stronger terms, going so far as to describe gossip as the “garbage of stupid silly ignorant people” (Lorenzo, 2006). Is this too harsh? Cruz et al. (2021) propose a much more neutral definition in their analysis of frameworks to study gossip, concluding that gossip is “a sender communicating to a receiver about a target who is absent or unaware of the content”. Whether the gossip conveys positive or negative content — otherwise known as its valence — is not a requirement of the definition itself. Gossip, then, is not always “unkind” (Oxford Learner’s Dictionaries, 2023) or “garbage” (Lorenzo, 2006). In fact, with a bit of further reading, we can see that this “informal talk” has played an important part in our evolution and even serves positive purposes in society. In the first sense, gossip is an important facilitator of safety. It allows dangerous situations to be identified: spreading the knowledge that a certain individual is prone to violence, for instance, ensures the rest of a community takes care of their own safety with regards to that individual. On a different note, passing about the fact that another individual is skilled in certain aspects of resource procurement allows wider access to these resources. It is easy to see in these examples how gossip could give a selective advantage in the survival of societies. But the influence of gossip goes further than this. It has been shown that gossip in fact encourages cooperation and generosity (Wu et al., 2015). How? The crucial mediator is reputation (Nowak, 2006). Reputation is incredibly important - see Taylor Swift’s 2017 album for more. A poor reputation leads to ostracisation, and for an individual in prehistoric societies, this could be fatal. Cultivating a good reputation among peers thousands of years ago, as today, improves the chances of success in life by increasing access to resources and the willingness of others to help you. Positive gossip can facilitate all this. So, how do we foster positive gossip? What will encourage someone to put in a good word for us? The most effective approach is to act in a way that benefits that individual. It predisposes them to spread the word of our generosity, helping to build a reputation for goodness that will in turn have positive outcomes for ourselves. Thus, it’s easy to see how behaviours that foster good gossip are incentivised in our everyday lives. This propensity to spread the knowledge of how certain individuals interact with others has been incredibly impactful in the development of human societies. The fact that our species can flourish and sustain itself in such immense populations requires a high level of cooperation - which enables us to share resources and productivity - even with people we do not know. Otherwise known as indirect reciprocity, this ability to work with strangers is enabled by reputation (Nowak, 2006). How else do we know that it is safe to interact with a stranger, other than through the means of gossip, which informs us of their reliability and trustworthiness? But what about when gossip is incorrect? The Oxford definition hints at the possibility that information spread through gossip “may be…not true”. Can untrue gossip hinder our progress, by limiting interactions with individuals who may have the potential to help us, or promoting those interactions that would better have been avoided? And if gossip can be incorrect, does that not render reputation meaningless? What is the incentive to be good, if gossip could label you as a bad egg, regardless (Nieper et al., 2022)? Incorrectly negative gossip can be extremely impactful for the subject of that gossip. Studies have shown that it decreases productivity and prosocial behaviour - not to mention burdening victims with the psychological effects of ostracisation, injustice and loneliness (Kong, 2018; Martinescu et al., 2021). Through gossip, we can exert immense power over other beings. It is understandable, then, that we fear gossip, and try to discount it by painting it as “garbage” (Lorenzo, 2006), “unkind” or “not true” (Oxford Learner’s Dictionaries, 2023). And yet, whilst negative gossip can be a detriment, positive gossip can yield great benefits, reinforcing prosocial behaviour, fostering cooperation and promoting generosity. So, rather than fearing gossip, perhaps we ought to acknowledge its benefits and harness it for good. Perhaps it's worth considering how we can each use gossip to exert a bit of good upon our world.

< Back to Issue 7 Pointing the Way: A Triangular View of the World by Ingrid Sefton 22 October 2024 edited by Hendrick Lin illustrated by Aisyah Mohammad Sulhanuddin You, my friend, are living in a world created by triangles. Since the dawn of time, this humble three-sided polygon has quietly shaped the evolution of human civilisation. As you gaze around, you can likely spot a triangle or two tucked within your surroundings. This may be of no surprise to you. Externally, the triangle governs the material construction of our world, underpinning the foundations of countless engineering and architectural designs. Yet these more obvious physical constructions are just one contribution of this pointy, three-sided shape to modern society. Indeed, it is where the role of the triangle remains invisible that it harnesses the most power. Triangles have played an integral role in sailing and modern navigation systems, having enabled us to explore all corners of the Earth. Beyond this, let us not forget the massive contributions this shape has made to the development of 3D modelling, used everywhere from graphic design and animation to CGI. All thanks to the simple, unassuming triangle. The physical, the navigational and the digital. Three key sides of the triangle’s influence in shaping the modern world. The Physical The triangle's importance in the physical world stems from its inner strength. Unbeknownst to many, it is the strongest two-dimensional shape that exists, with its power amplified in three-dimensional polyhedrons derived from triangles. How can this unique strength be explained? Consider applying force to one corner, or apex, of a triangle. This force is distributed down either side of the triangle and as these sides are compressed, the base is stretched outwards. Weight can therefore be evenly dispersed across the shape, preventing it from bending and breaking (Saint Louis Science Center, 2020). It is for good reason that the triangular shape underpins many fundamental principles of architecture and design. Perhaps the most iconic of the structures that utilise this shape are the Pyramids of Giza, one of the Seven Wonders of the Ancient World. Constructed in the early 25th Century BCE, they housed the tombs of ancient Egyptian pharaohs and are the last remaining Wonder that exists today. The tallest of the Pyramids, known as the Great Pyramid, originally soared as high as 147 metres above the ground, though today erosion has reduced it to 138 metres (Encylopedia Britannica, 2024a). This architectural feat was monumental for its time, and to this day, how exactly the Pyramids were constructed remains a hotly contested debate amongst archeologists and engineers. One proposition is that large ramps were used in conjunction with a complex system of ropes, sledges and levers to haul stone blocks up (Handwerk, 2023). Whatever the method of construction may have been, these ancient wonders have stood the test of time for over 4500 years - a remnant of one of humanity's first advanced civilisations that exemplifies the scale, strength and resilience of construction made possible by triangles. Triangles also play a crucial role in the construction of seemingly dissimilar shapes. This is highlighted in the case of geodesic structures - spheres constructed from a network of triangles approximating a rounded shape, like a soccer ball. First developed in the 20th Century by architect Richard Buckminster Fuller, these domes are lightweight and able to distribute stress across large, arching structures (Encylopedia Britannica, 2024b). Since Fuller’s earliest constructions, these domes have been widely utilised in the construction of stadiums, planetariums and even "glamping" accommodations. One notable example is the Eden Project - the world's largest biodome botanical garden in the United Kingdom, housing thousands of plant species over 5.5 acres of land (Eden Project, 2024). The interconnectedness of the triangles allows for maximum sunlight exposure across wide spaces, creating an ideal environment for plant photosynthesis and cultivation. Intriguingly, Fuller's use of triangles in this innovative manner led to a breakthrough in the far-away field of synthetic chemistry. Scientists Robert Curl, Harold Kroto and Richard Smalley discovered the nanomaterial Buckminsterfullerene, or “the Buckyball”, after the scientists realised the structure's similarity to Fuller's geodesic spheres (The Stanford Libraries, 2024). This led to the discovery of a new class of materials known as fullerenes. The scientists were subsequently awarded the 1996 Nobel Prize in Chemistry for elucidating this molecule’s structure (The Stanford Libraries, 2024). Balancing power with versatility, triangles form the crux of our built environments at both an atomic and architectural level. The Navigational Remember those sine and cosine formulas your maths teacher insisted had important real world applications? Turns out they weren’t kidding. Triangulation is the process of finding an unknown location of an object by forming a triangle between this object and two other reference points. Sine, cosine and tangent, the main trigonometric ratios, are used to relate the sides and angles formed within a right triangle and hence, determine the position of an unknown point. For centuries, humans have turned to triangles as a means to find their ways. Sailors, in particular, have long used landmarks and celestial objects like the stars to orient themselves at sea. By observing the angle between known locations (or stars) and using basic trigonometry, navigators could calculate distances and determine their precise location. Moving to a more global scale of navigation becomes a bit more complicated, as the Earth is a sphere and not a flat surface (although some may beg to differ…). A more advanced form of triangulation known as trilateration underpins the Global Positioning System (GPS) in order to determine three-dimensional coordinates of a receiver. Instead of angles, GPS utilises the time taken for radio signals sent from satellites to reach a receiving device on Earth. A connected system of navigation satellites circles the Earth, each sending out signals with the location and time it was sent by that satellite. By measuring the delay between the time of signal reception and the broadcast time, the distance from the receiver to each satellite can be computed (Federal Aviation Administration, 2024). Once distances to at least three satellites are known, the receiving device can determine its own three-dimensional position, employing similar techniques to triangulation. GPS data is not only used to guide your Google Map directions. Analysing the positions of satellite stations and their movements is a crucial tool for monitoring volcanic and seismic activity (Murray & Svarc, 2017). Recent breakthroughs have even suggested that there may be a future for utilising the GPS to detect earthquakes before they happen (Rao, 2023). From the seas to the skies, triangles allow us to push the boundaries of exploration while always guiding us home to safety. The Digital What does connect-the-dots have to do with triangles or 3D modelling? A connect-the-dots drawing begins with nothing but some labelled dots. Yet as each dot is joined by a straight line, a complex and curved picture emerges. The more dots you use, the smoother the picture looks. Consider now trying to design a three-dimensional surface. Just as you might use dots to approximate a curve, triangles serve as building blocks for constructing complex surfaces. By taking enough triangles and joining them at their edges, we too can approximate intricate and multidimensional structures. In 3D modelling, objects are represented as meshes - models consisting of vertices (points in 3D space) connected by edges to form polygons and thus, the surface of an object (Stanton, 2023). To define a flat surface oriented in a plane, a minimum of three distinct points are needed. Triangles are the simplest shape for constructing these planes as they are coplanar, meaning any three points in space will always form a flat surface (Licata & Licata, 2015). This makes them perfect for modelling complex 3D shapes out of interconnected triangles. Animation, gaming, graphic design and computer generated imagery (CGI) in movies are just some of the many varied applications that utilise these mesh modelling techniques to create intricate 3D models, with curved and highly detailed surfaces. Additionally, there exist efficient computer algorithms that are optimised to dissect objects into hundreds of thousands of flat triangles. A complex, digital representation of any object can therefore be easily portrayed as a simple collection of points and triangles. Combined with their simple geometric properties, triangles can then be processed quickly by modern Graphics Processing Units (GPUs), optimising their performance in real-time applications. Add in lighting, shading and smooth deformation, and you will find yourself with an intricate, three-dimensional model. Pointing the Way Forward For too long, the triangle has been overshadowed by its more popular cousin, the square. Yet, what is a square? Two triangles put together. The simplicity of this three-sided shape allows it to integrate within our society, with its contributions often invisible to the naked eye. From the physical, to the navigational and the digital, modern human society is built on the triangle. Maybe that trigonometry class wasn’t so pointless after all. References Eden Project (2024).

< Back to Issue 7 Timeless Titans: Billionaires defying death by Holly McNaughton 22 October 2024 edited by Arwen Nguyen-Ngo illustrated by Esme MacGillivray Humans are destined to face an unavoidable end, but what if we weren't? What if humans could push the boundaries of death and become "un-ageable"? What would be the consequences if the world's top apex predators became immortal? The concept of anti-ageing and the quest for eternal life is not new. Cleopatra supposedly bathed in donkeys’ milk to reduce wrinkles. The first emperor of the Qin dynasty (221-206 B.C.), tried to achieve immortality by taking pills. Unfortunately for him, the key ingredient was the highly toxic substance—mercury. In 16th century France, members of the nobility would drink gold to preserve youthful looks. Much like in the past, today’s leading figures in the anti-ageing field are those with power and wealth. Today, the same obsessive quest for youth persists, but now it is backed by cutting-edge science and more importantly, staggering wealth. This article delves into the latest anti-ageing trends—pills, specialised diets, and more—championed by modern-day billionaires. We’ll explore the innovations they fund, and more provocatively, what it means for humanity when death is no longer inevitable. Anti-ageing pills The first “key” to anti-ageing is metformin, which dates to the1920s and was first discovered in the medicinal herb Galega officinalis . It lowers blood sugar levels and is taken as a popular treatment for type 2 diabetes (Bailey, 2017). Metformin works by tricking your body into thinking there is not enough energy, lowering blood glucose levels, and helping the insulin your body makes to work better. In a 2014 clinical study, patients with type 2 diabetes initiated with metformin had longer survivals than non-diabetics who did not receive the drug (Bannister et al. 2014). Although this is a correlation, not causation, some studies state Metformin has increased lifespan in mice (Martin-Montalvo et al., 2013). While we are anticipating the results of a trial on the effects on humans, and particularly the effects on non-diabetic lifespan, some are already convinced by the results from preliminary studies, such as Byran Johnson. Johnson is a self-proclaimed Professional Rejuvenation Athlete and founder of Project Blueprint. The Blueprint protocol is an extensive regimen of exercise, health tests, supplements, and a strict diet, to reverse biological age. Bryan has been following the protocol since 2021 and has successfully slowed down his rate of ageing to 0.76, meaning that for every year, Bryan is only ageing 277 days. Luckily, it only costs him 2 million a year. As part of the protocol, Bryan takes several prescription drugs daily, including metformin twice a day and rapamycin. Rapamycin is another promising “key” anti-ageing drug that works as a mTOR inhibitor. mTOR is a key component in cell growth, proliferation and survival. By inhibiting mTOR, cell growth and protein synthesis processes are slowed, thus reducing the chance of pathology (disease and/or injury) of cells and tissues. It has been shown to extend the lifespan of mice, yeast, worms and fruit flies (Harrison et al., 2009) and in 2018, elderly humans given rapamycin showed promising results with improvement in immune function and decreased infection rates (Mannick et al., 2018), which could ultimately lead to longer lifespans. Young blood transfusion Throughout history, blood has been a popular anti-ageing remedy. In the 15th century, Pope Innocent VIII drank the blood of three young boys, to heal his ailments (Scott & DeFrancesco, 2015). It did not work. The term “Young Blood transfusion” is now used to refer to the practice of transfusing blood from a young person into an older one to tackle age-related diseases. The rationale comes from parabiosis experiments. Parabiosis is the anatomical and physiological union of two organisms, and in the 1950s it was performed on two mice, surgically stitched together. A month after the procedure, the older mice showed rejuvenation (Conboy et al., 2005). In 2017, a new startup called Ambrosia emerged offering transfusion from young people at $8,000 a session. According to the U.S Food and Drug Administration, there were no clinical benefits of this treatment, and it was shortly shut down. PayPal founder Peter Thiel believes he will live to be 120 years old; a fan of young blood transfusions, he also credits his future success to taking human growth hormones daily and following a strict paleo diet. The science of which diet is best for anti-ageing is constantly changing. The paleo diet cuts out sugar, carbohydrates and highly processed food and is praised by celebs, but is not currently supported by science for having anti-aging benefits. Other diets such as intermittent fasting, keto and veganism are all praised for their anti-aging properties, but again the claims are under-researched. However, there is a growing body of evidence that a whole-food, plant-based diet can aid in the prevention, and in some cases reversal, of chronic diseases (Solway et al., 2020). For example, in Loma Linda, California, one of the world's five original blue zones (areas of the world with the healthiest, longest-living populations), the life expectancy is 10 years longer than the average American, which has been linked to the high number of Adventist vegetarians in the community. The key link between all five blue zones is a mostly whole-food, plant-based diet. Ethical and social implications – consequences of immortal humans The cure to ageing is still a while away but there is already a growing body of evidence of how we can extend our lifespans, but is that a good idea? The first argument against extending human lifespans is the risk of furthering the gaps in inequality. There is already a 30–40-year life expectancy gap between first-world and third-world countries. As highlighted in this article, it is primarily the wealthy benefiting from advancements in anti-ageing. Although, it is the responsibility of politicians and governments to remove the disparities worldwide. Thus, the question arises – should our focus and resources be directed towards addressing the health crises in developing countries instead? The second argument is overpopulation. An interesting study that looked at a 100-year projection of population size if no one aged after 60 showed that total population size only increased by 22% or 9 million to 11 million (Gavrilov & Gavrilova, 2010). They also pointed out that many members of society may choose to reject new anti-ageing technologies due to religious reasons, fear of side effects and/or costs. I would also like to point out that the world’s declining birth rates due to increased fertility issues may also mean overpopulation won’t be a near-future issue. An increasing population size does however mean increased demand for finite resources like water. Increases in water demand could cause an increase in civil and international conflicts over existing water supplies. In Australia, water scarcity is already a persistent issue, given the relatively dry and variable climate and an increased population size will see demand rise above our limits. To conclude, science has not found a cure for mortality, but with the development in age reversal or anti-ageing science, we may see the longevity of life increasing as well as quality of life. There are several ethical and social implications of an “un-ageable” race, but most importantly, developments in the anti-ageing community may allow loved ones to be healthier for longer.

Its history is linked to Galega officinalis (also known as goat’s rue), a traditional herbal medicine in Europe, found to be rich in guanidine, which, in 1918, was shown to lower blood glucose. Guanidine derivatives, including metformin, were synthesised and some (not metformin) were used to treat diabetes in the 1920s and 1930s but were discontinued due to toxicity and the increased availability of insulin. Metformin was rediscovered in the search for antimalarial agents in the 1940s and, during clinical tests, proved useful to treat influenza when it sometimes lowered blood glucose. This property was pursued by the French physician Jean Sterne, who first reported the use of metformin to treat diabetes in 1957. However, metformin received limited attention as it was less potent than other glucose-lowering biguanides (phenformin and buformin), which were generally discontinued in the late 1970s due to high risk of lactic acidosis. Metformin’s future was precarious, its reputation tarnished by association with other biguanides despite evident differences. The ability of metformin to counter insulin resistance and address adult-onset hyperglycaemia without weight gain or increased risk of hypoglycaemia gradually gathered credence in Europe, and after intensive scrutiny metformin was introduced into the USA in 1995. Long-term cardiovascular benefits of metformin were identified by the UK Prospective Diabetes Study (UKPDS) in 1998, providing a new rationale to adopt metformin as initial therapy to manage hyperglycaemia in type 2 diabetes. Sixty years after its introduction in diabetes treatment, metformin has become the most prescribed glucose-lowering medicine worldwide with the potential for further therapeutic applications.

< Back to Issue 2 Law and Order: Medically Supervised Injecting Centres Keeping people safe from the harms of drug use is an important public health goal, but some question the value of medically supervised injecting centres in improving health and community outcomes. by Caitlin Kane 10 December 2021 Edited by Tanya Kovacevic & Natalie Cierpisz Illustrated by Rachel Ko Medically supervised injecting centres (MSICs) are an exemption from the standard practices of law and order: instead of policing drug users, these facilities allow people to bring illegal drugs to dedicated, clean settings where they can legally inject themselves and receive medical care if required. Essentially, drugs like heroin and ice can be used in a safer environment often integrated with other health and welfare services. These centres aim to improve public health and amenity outcomes, but are criticised for facilitating drug use. Australia’s MSICs have been controversial since their inception. The first local MSIC opened in Kings Cross, Sydney in 2001, following a Vatican intervention to withdraw nuns and the arrest of a Reverend for opening a short-lived unsanctioned injecting facility (1,2). Local businesses and residents feared a nearby “safe haven for drug users” would accelerate rampant and disruptive public drug use and threatened last-minute legal action (3). The centre is still in operation and has now supervised more than one million injections without a single overdose fatality (1,4). Medical director Dr Marianne Jauncey explained how the Kings Cross centre saves lives in a discussion with the ABC this year (5). Yet before Australia’s second MSIC opened in Richmond, Melbourne in 2018, commentators continued to decry the proposition as accepting and passively encouraging drug use. Nationals MP Emma Kealy announced, "It sends the wrong message to our kids and effectively says we've given up on preventing drug use” (6). With consultation ongoing to establish a third Australian MSIC in the Melbourne city centre, it’s valuable to detangle the misconceptions around the effects of MSICs on communities and their value as public health tools. Much controversy around Australia’s MSICs centres on three concerns: the number of overdoses occurring on premises, the attraction of drug addicts to the areas, and the drain on public health resources. Examining the data collected by public health scientists demonstrates that these concerns are unfounded and supports the continued consideration of MSICs as effective public health interventions. WHAT EFFECT DO MSICS HAVE ON OVERDOSES? It’s critical to understand that MSICs are proposed for areas with heavy drug use, particularly use in public settings and causing medical emergencies like overdoses. At the turn of the millennium, the streets of Kings Cross were a major site of public drug use, overdoses, and ambulance callouts (7). In 2000, one spate of thirty-five Sydney overdoses, four fatal, occurred in a single twenty-four hour period (3). At the time, 10% of all drug overdoses in Australia occurred in Kings Cross (3). In response, the Kings Cross MSIC opened in 2001 following decades of mounting evidence in Europe. European drug injection centres had been operating since the 1970s, with growing official support through the 1990s in countries like the Netherlands, Switzerland, and Germany (2). Evaluations reported successful reductions in public nuisance, improved service access, and declining overdose deaths (2). Switzerland demonstrated annual overdose deaths halved in four years and a tenfold reduced chance of hospital admission in MSIC overdoses compared to overdoses on the streets (2,3). Similarly, the Richmond MSIC opened in 2018 as a response to the highest heroin death toll in sixteen years and record ice deaths in 2016, with the major drug market in Richmond considered the “epicentre of Melbourne’s heroin crisis” (8). It could be easy to criticise the overdoses occurring on the MSIC premises, but these overdoses predated the MSICs and prompted their opening after other strategies failed to address the crisis. As public health interventions, MSICs are most effective in areas with high densities of public drug use, like Kings Cross and Richmond, which is why these sites were chosen to house MSICs (7). A systematic review of studies covering a range of MSIC facilities, including Kings Cross, concluded that all facilities had a significant reduction in overdose deaths in their local area (9). Ambulance callouts for overdoses near Kings Cross decreased by 68% within six years of opening (9). In Richmond, emergency medical attendances to drug overdoses near the MSIC have decreased significantly. Only 30 of the 2657 overdoses treated at the MSIC in its first eighteen months led to ambulance attendance and there has been a 25% decrease in naloxone administration, a treatment for opioid overdose, by ambulances in the one kilometre radius of the MSIC (10). The impact of drug overdoses in these areas has been greatly mediated by the presence of the MSICs. In 2017, the Kings Cross MSIC celebrated one million injections with zero fatal overdoses (1). The lack of a single overdose death at these facilities despite the number of overdoses should be considered a mark of commendation (1,5,10,11). DO MSICS ATTRACT DRUG USERS TO THE AREA? A second concern is that MSICs attract drug addicts to the area in which they are situated. However, this misattribution of causality arises because MSICs are purposefully located in areas with pre- existing drug markets. Major drug markets create local hotspots of public injection as many drug users inject immediately to reduce withdrawal and avoid police attention (7). These areas of high public drug use became candidates for the establishment of MSICs because drug users already frequented the area. Before the MSIC opened, over 90% of ambulances attendances for overdoses in Kings Cross were within a 300 metre radius of the proposed MSIC location. The area was chosen for an MSIC because of the existing disruption caused by public drug use and overdose. Improving public amenity, such as decreasing encounters with discarded needles, drug injection and overdose, is one of the most important goals of MSICs (2,11). Despite initial outrage in Kings Cross, support for the centre among local businesses increased to 70% in 2005, and local perceptions were positive (11,12). Monitoring of the area found no increase in drug-related crime, dealing or loitering after the Kings Cross MSIC opened (11). This is also supported by more recent findings in 2017, that alongside improving local amenity and reducing ambulance callouts, the Kings Cross MSIC did not draw dealers and addicts to the area in a ‘honey pot’ effect (6). This was corroborated by a systematic analysis which found no increase in drug-related violence and crime related to MSICs in Sydney and Vancouver across the results of four studies (9). The same review concluded that MSICs do not promote drug use, crime, drug trafficking, or increase new drug users (9). Likewise, demand for the Richmond MSIC was created by the existing Richmond drug market and disruption to the community, with 46 of 49 local stakeholders found to support a proposed MSIC in a 2017 consultation (11). Alongside harm minimisation, one submission highlighted the “significant toll on health workers and members of the local community who have to deal with the aftermath of overdoses and for children to see people in public in such a terrible state” as motivating their support for establishing a Richmond MSIC (11). Since opening, concern that additional people would travel to use the centre was abated by findings that travel distance was a major reason for not attending the MSIC and residential information collected from Richmond MSIC users (10). Regarding public amenity, an evaluation found mixed results in its eighteen months of operation, with reduced sightings of public injections and incidents at the neighbouring school, but decreased perception of safety and community support for the MSIC (10). It remains to be seen how this trend develops with continued operation of the centre. DO MSICS DRAIN PUBLIC HEALTH RESOURCES? While the primary goal of MSICs is to reduce the harms associated with overdose and public drug injection, MSICs have broader public impact through integration with complementary social and medical services. People who inject drugs are subject to associated harms, ranging from increased risks of blood-borne diseases (HIV, HBV, HCV) and psychiatric disorders to homelessness, crime, and prostitution (2,10). This socially marginalised group often lacks adequate access to healthcare, despite the significantly increased risks of harm and death (9). Analysis of the Vancouver MSIC found the streamlined and preventative healthcare provided to drug users was quantifiably more effective and saved both millions of dollars and 920 years of life over 10 years (9). In 2008, an economic review of the Kings Cross MSIC determined that averted health costs alone made significant savings for the government, and the value of prevented deaths would pay for operating costs more than 30 times (13). Furthermore, unprecedented access to drug users can facilitate important research to investigate and validate public health issues and strategies. For example, a 2017 paper analysed the rates and severity of overdoses for illicit and prescription opioids with data from the Sydney MSIC, producing clinically salient research enabled by access to marginalised and vulnerable populations (14). Alongside reductions in ambulance callouts and overdose complications which are instead managed at the centre, MSICs can improve the reach and delivery of health and social services for drug users, including blood-borne disease screening, drug treatment and rehabilitation, and mental health counselling (9,10). Engagement with MSICs and integrated services promoted safer injecting practices, health and social service use, and entry to treatment programs. The overall proportion of MSIC-attending drug users in treatment programs was 93%, compared to 61% of first-time attendees at the facility, demonstrating the improved effectiveness of reaching drug users with healthcare programs (15). Across seven studies on drug user uptake of MSICs, 75% of drug users reported improvements in their behaviours regarding public amenity and safe injection (9). This effect was particularly strong for marginalised and at-risk attendees, like those who were homeless, Indigenous, had previously overdosed, and others with self-identified need (15). MSICs contribute massively to overall public health strategy, through both direct harm reduction and efficiently increasing access to existing services. BEYOND MEDICALLY SUPERVISED INJECTING CENTRES MSICs in Australia and across the world have been successful in achieving their objectives; reducing drug-associated harms and community exposure to public injection and overdose (9,12). The continued controversy around MSICs despite their established and validated success betrays widespread misunderstanding around the nature of addiction, the effective treatment and harm reduction for drug abuse. In 2017, despite the support of three coronial recommendations and the Australian Medical Association for a Richmond MSIC, MP Tim Smith asked, “Since when did we start rewarding people who break the law, since when did drug users become victims, we need to enforce the law" (6,8). Political discourse that distorts the goals of MSICs and distracts from their established efficacy only serves to stagnate evidence-based action and weaken Australia’s response to damaging drug use. While MSICs attract stagnating attention and controversy, public health issues around drug addiction and opioid dependency remain unaddressed (16). In Australia, prescription drug abuse causes ten times more overdose deaths than illicit drug abuse, and prescription opioids provides a pathway to the use of illegal opioids, like heroin and fentanyl (14,16). As seen in the 2017 investigation into the prevalence and consequences of opioid overdoses in the Kings Cross MSIC, prescription opioid injection is a significant form of harmful drug use (14). MSICs are a useful and effective tool to combat drug abuse, but are not intended to solve all drug-pertinent problems; they must be incorporated into broader public health and crime strategies (9). Drug abuse is a seriously complicated problem, so it makes sense to have misconceptions around the impacts of MSICs. Effective drug policy needs to consider MSICs as a component of a broader public health strategy and educate the public about responses to drug abuse. It’s critical for communities and decision-makers to stay informed and choose evidence-based strategies to address the public health and amenity goals around drug use.

< Back to Issue 8 Terror Birds: The Discovery of Prolific Hunters by Jason Chien 3 June 2025 Edited by Luci Ackland Illustrated by Max Yang It began in the 1880s with a toothless jaw. And then some leg and hip bones and a vertebra were found. The leg bones, comparable in size to those of African ostriches, also bore similarities to fossils of the unrelated, giant, flightless Gastornis birds of Europe. Across the 1880s and 1890s, these discoveries slowly led archaeologists to realise they were dealing with a hitherto unknown group of giant, fearsome birds (1). With more complete fossil specimens subsequently discovered and clues provided by their unique morphologies, it did not take long for paleontologists to realise that all members of the “terror birds”, or Phorusrhacids, were carnivores, and that some were apex predators. Through isotopic dating of sediments in which terror bird fossils were found, paleontologists concluded that this taxonomic family existed from 43 million years ago (mya) – possibly even earlier – until their extinction 100,000 years ago (although no single species of Phorusrhacids survived this long) (2,3). Various fossils have since been found in South America and deemed to belong to Phorusrhacids species. Though most fossils have been found in Argentina, they have also been found in Brazil, Uruguay, Chile, Bolivia, Peru, the Southern United States and most recently, in Colombia. Throughout South America, there are various more fossils currently being discovered, some of which are being assigned to new species. At the moment, there are at least 18 characterised species, with some fossil-described species in contention of belonging to Phorusrhacids (4). Although size differed between species, there are morphological features common to all Phorusrhacids. Species such as Kelenken guillermoi , Phorusrhacos longissimus , and a few individuals of the North American Titanis walleri were giants at least 2 meters tall, weighing more than 100kg. Meanwhile, the shorter North American Titanis walleri was 1.4 to 1.9m in height and weighed an impressive 150kg (5,6). At the other extreme, the comparatively tiny Psilopterus bachmanni weighed only 4.5kg (7)! Smaller Phorusrhacids preyed on small vertebrates and invertebrates, with some species perhaps capable of short flight durations, filling a different predator niche than their larger counterparts (7). Though the prehistoric South American environment, unlike today's, was generally grasslands and woodlands, different Phorusrhacids species lived in distinct habitats. These differences include variation in aridity, as well as differences in the large and small prey present in different localities (8). Furthermore, Earth’s overall climate also varied during the more than 40 million years in which terror birds were present, such that the habitats of different terror bird species living in different periods of geologic time also differed. Reconstruction of some specifics of each locality’s prehistoric environment is not always possible (9). Lastly, the earliest and latest discovered fossils of each species indicate the period during which a species survived, but the boundary at which a species becomes distinctly different from an ancestral species is not always clear (10). Here are some terror birds whose habitats are better understood: Phorusrhacos longissimus : an environment with water bodies and a mix of open and enclosed areas. For instance, the first discovered terror bird fossils originated from longissimus individuals living in what was later reconstructed to be temperate forests and bushlands. This bird survived during parts of the Miocene period (23 mya to 5 mya) (8,10) Titanis Walleri : Tropical grasslands with springs, similar to today’s Florida. This species lived in a more unique environment than other terror birds, from 5 mya to 1.8 mya (5,6) But what did all the terror birds, large and small, have in common regarding how they hunted? From the structure of the terror birds’ legs, feet and hips, a paleontologist can infer features that suggest some terror birds were fast runners (11), or otherwise had limbs adapted for running. Despite natural uncertainties associated with paleontology, there is some headway into the running speeds of some terror bird species. For instance, the running speed of the 1m tall, 45kg Patagornis marshi was estimated to be 50 km/h (12,13), more than enough to chase down their prey. Once the prey was chased down, some terror birds would use their powerful legs to kick and incapacitate it, as suggested by features indicating strength in the bones of some species (14). Furthermore, some terror bird species possessed sharp claws, which are thought to have been used to stab prey (14). Though not all terror birds – especially the smaller species – were fast runners, all terror birds used their beaks when hunting, relying on beak strikes rather than the biting force used by many other birds. Their long necks were able to be flexed far backwards and forwards, allowing them to frontally strike prey repeatedly and powerfully with their beaks. Unlike that of many other birds, their ancestors and even their closest living relatives (the seriemas), the skull structure of most terror bird species is such that there is no moveable hinge between the upper beak and the skull due to the fusion of some bones in that region. This adaptation allows the skulls of Phorusrhacids to specifically resist loads from striking prey without suffering damage – though only if the strikes are precise (15). Other interesting features of the terror birds include gaze stabilisation and their hearing capacity. Based on their inner ear anatomies, the terror birds had the capacity for fast head movements while maintaining sight on their prey, evidencing their agility. Further evidence from the inner ear anatomies indicate the enhanced ability of the terror birds to hear low frequency sounds. Low frequency sound waves can travel a longer distance and are less affected by obstacles that absorb and scatter sound, allowing the terror birds to hear prey far out of sight. If terror birds were capable of producing low frequency sound as well, this would have enabled them to communicate from long distances apart (11). If one were to picture the heterogeneity of the terror bird species, they would probably imagine a predator in the act of hunting, or doing something else. In periods of geologic time with the greatest terror bird diversity, you may even be able to picture individuals of two different terror bird species, though you wouldn’t see two species of apex predator terror birds together (10). However, if you were to imagine beyond the bird, you would wonder how the flora, the other animals present, the climate, and many more all played a role in the story of the terror birds. Tracing the lineages of the Phorusrhacids backwards, one would reach a bird capable of flight. The characteristic of complete flightlessness arose specifically in large Phorusrhacids species, which were apex predators that consumed large mammals (10). The extinction of dinosaurs, and the absence of large placental carnivores in South America from 65 mya to 3 mya, made the apex predator niche unfilled (16). Subsequently, they started to be filled by the ancestors of large Phorusrhacids. But with diverse fauna, why did terror birds become one of the apex predators, and not many other animal groups, for instance the South American marsupial mammals? It is a persistent evolutionary mystery in perhaps all of paleontology, with many possible explanations but few, if any, ways to test them (17). Two hypotheses have been proposed to explain the demise of the terror birds: the encroachment of North American fauna into South America beginning 9 mya; and the episode of global cooling that occurred 3 mya. Due to continental drift, the North and South American continents were drifting towards each other, with a land bridge formed by 3 mya, though the movement of some groups of animals across the gap began much earlier. Known as the Great American biotic exchange, North American placental carnivores, some of them large predators, moved into South America and rapidly diversified (9). The former hypothesis suggests that competition with these predators drove the terror birds to extinction. In the latter hypothesis, rapid cooling not only affected the terror birds, but also affected the ecosystems where the terror birds lived (9). Despite the lack of direct evidence that is able to resolve this uncertainty, the contingent belief is that the latter hypothesis is more likely to be true and that the encroachment of North American fauna in the former hypothesis had a small to none effect on the extinction of the terror birds (9,12). Attached to every bone and bone fragment is a history of discovery, of being dated, of measurement, of cataloging and sometimes, of reexamination. Every bone was once a part of the organism, each with the potential to yield valuable information. As a testament to how far science has come since the early days of fossil hunting, we now have a much larger cache of fossils to make comparisons to, we have the tools to model an organism’s mass and some of its biomechanics based on fossilised bones, and we even have the means to look at the bone structures under a light or electron microscope to infer some of an organism’s probable behavioural characteristics. The fact that we figured out this much about the birds is astounding. Fossils form only under specific conditions – an organism has to be buried before there is a chance of it being eaten and then covered with sediments in conditions where microorganisms that decompose the body cannot survive (such as anoxic environments). Scientists estimate that the fossil record contains less than 0.1% of all species that have ever lived (18)! Furthermore, it is common ecological knowledge that for every ecosystem, the population of apex predators is small and are less likely to be preserved in the fossil record. Many mysteries, ranging from their colours to their various behaviour, remain. Perhaps these mysteries are what deepen our curiosity and account for our fascination with these organisms. Still, we are truly fortunate to be able to infer so much from the terror birds’ unique morphology and get to know of them and their stories, beyond just what we imagine them to be.

By Gavin Choong < Back to Issue 3 Love and Aliens By Gavin Choong 10 September 2022 Edited by Khoa-Anh Tran and Niesha Baker Illustrated by Ravon Chew Next Neither Daniel Love nor Brendan Thoms were Australian citizens, but they were both recognised as First Nations Australians by law. Under legislation, “aliens” who commit crimes with a sentence of over a year may be removed from the country. (1) Due to their non-citizenship, the then Minister for Home Affairs Peter Dutton classified these men as aliens and tried to deport them after they were convicted of serious crimes. This attempt failed. The High Court of Australia ruled, in the hotly contested landmark decision of Love v Commonwealth, that Indigenous Australians could not be considered aliens under Australian law because of the “spiritual connection” they hold with the lands and waters of the country we live in. (1) Effectively, this barred the deportation of Love and Thoms but also sent astronomical ripples through the fabric of our nation’s legal framework. This year, major challenges to the decision made in Love v Commonwealth have arisen. Of the arguments put forward, some protest the judicial activism of the judges – that is, them going above and beyond written law to produce a fairer ruling. For example, many contend the term spiritual connection bears no actual legal meaning. However, with a history dating back upwards of seventy-thousand years, two hundred and fifty languages and eight hundred dialects, complex systems of governance, deeply vested religious and spiritual beliefs, and a profound understanding of land, it would be ignorant to argue this rich culture should simply be disregarded in the face of the law. This article adopts a scientific lens and delves into an empirical basis for the spiritual connection Aboriginal Australians share with country, traversing from Dreamtime to spacetime and beyond. THE DREAMING: FROM NOTHING, EVERYTHING From nothing came everything. Nearly fourteen billion years ago, a zero-volume singularity held, tightly, all the energy, space, and time from our current universe. In the moment of creation, temperature and average energies were so extreme all four fundamental forces which shape the universe, as we know it, acted as one. Cosmological inflation followed, allowing for exponential expansion and rapid cooling. Within a picosecond, the four fundamental forces of nature – gravity, electromagnetism, weak interactions, and strong interactions – emerged independently. These forces interacted with matter, resulting in the formation of elementary particles now coined quarks, hadrons, and leptons. For twenty more minutes, elementary particles coupled to form subatomic particles (protons, neutrons) which in turn underwent nuclear fusion to create simple early atoms such as hydrogen and helium. From nothing, came everything. In an eternal present, where there had once been flat and barren ground, Ancestral and Creator spirits emerged from land, sea, and sky to roam the Earth. As they moved, man and nature – mountains, animals, plants, and rivers – were birthed into existence. Once these spirits had finished, instead of disappearing, they transformed into the world they had created, existing in sacred sites such as the night sky, monolithic rocks, and ancient trees. The Dreaming is a First Nations peoples’ understanding of the world and its creation. Importantly, it is an event which cannot be fixed in time – “it was, and is, everywhen,” continuing even today. Countless retellings have caused Dreamtime tales to diverge slightly, leading communities of Aboriginal Australians to identify with different variations of similar stories. (2) These fables refer to natural worldly features and sacred sites, whilst also incorporating favourable values such as patience, humility, and compassion. An example is the tale of the Karatgurk, told by the Wurundjeri people of the Kulin nation, about seven sisters representing what we now consider as the Pleiades star constellation. (3) The Karatgurk These seven sisters once lived by the Yarra River, where Melbourne now stands. They alone possessed the secret of fire, carrying live coals at the end of their digging sticks. (Crow ("trickster, cultural hero, and [another] ancestral being") called the sisters over claiming he had discovered tasty ant larvae. (3) The women began scouring, only to find viscious snakes underneath the dirt which they beat using their digging sticks. As they did so, the live coals flew off and were stolen by Crow who brought fire to mankind. The Karatgurk sisters were swept into the sky, with their glowing fire sticks forming the Pleiades star cluster. In theory, the extreme physical reactions occurring minutes after the Big Bang, paired with hyper-rapid cosmic inflation, should have resulted in a completely homogeneous universe with an even distribution of all existing matter and energy. Cosmological perturbation theory explains, however, that micro-fluctuations in material properties create gravitational wells resulting in the random grouping of matter. These aggregations formed the first stars, quasars, galaxies, and clusters throughout the next billion years. It took, however, another ten billion years for the solar system to form. Similar to Saturn’s planetary rings, the early Sun had its own rotating, circumstellar disc composed of dust, gas, and debris. According to the nebular hypothesis, over millions of years, enough particulates coagulated within the Sun’s spinning disc to form small, primordial planets. Early Earth was a hellish fire-scape as a result of constant meteoric bombardment and extreme volcanic activity. The occasional icy asteroids which collided with Earth deposited large amounts of water, vaporising upon contact – as our planet began to cool, these gaseous deposits condensed into oceans, and molten rock solidified into land mass. In the blink of an eye, early traces of modern humans fluttered into existence at the African Somali Peninsula. They were a nomadic people, travelling westwards and then north through modern day Egypt and into the Middle East. Ancestral Indigenous Australians were amongst the first humans to migrate out of Africa some 62,000 to 75,000 years ago. While other groups travelled in different directions filling up Asia, Europe and the Americas, ancestral Indigenous Australians took advantage of drastically lower sea levels during that time to travel south, as, back then, mainland Australia, Tasmania, and Papua New Guinea formed a single land mass (Sahul) while South-East Asia formed another (Sunda). In spite of this, the wanderers still had to possess the requisite sea-faring skills to traverse almost ninety kilometres of ocean. When the last ice age ended 10,000 years ago, rising waters from melting ice caps covered many of the terrestrial bridges early humans had once journeyed over. This severing allowed Indigenous Australians to foster culture and tradition in their very own passage of time, uninterrupted and independent until a British fleet of eleven ships approached Botany Bay thousands of years later. Significant parts of Australia’s coast were also submerged due to ice age flooding. As coastal Indigenous Australians observed this phenomenon, they recognised its significance through their tales. The Gimuy Walubara Yidinji, traditional custodians of Cairns and the surrounding district, are one of the many groups which reference coastal flooding in their geomythology. Gunya and the Sacred Fish Gunyah, who had lived on Fitzroy Island, went out to hunt for fish one day. Spotting a glimmer in the water, he plunged a spear towards it only to find he had attacked the sacred black stingray. The stingray beat its wing-like fins, causing a great, unending storm. Gunyah fled from the rapidly rising sea and managed to find refuge in a clan living on the cliffs of Cairns. Together, they heated huge rocks in a fire and threw them far into the sea. The pacific was once again pacified, and the Great Barrier Reef created. Isaac Newton proposed, in Principia Mathematica, that the strength of the force of gravity between two celestial bodies would be proportional to both of their masses. At the beginning of the twentieth century, Albert Einstein refined this concept with the theories of Special and General Relativity. His mathematical models suggested time and space were woven into a four-dimensional canvas of spacetime, and the presence of massive objects such as black holes and stars created gravitational wells which distorted spacetime. Within these distortions, bodies closer to large masses would conceive time and space differently than those further away. This unique phenomenon, for example, means astronauts living onboard the International Space Station age fractionally slower relative to us grounded on Earth. Einstein was also able to find that as the velocity of any given body increased to that near the speed of light, it would gain an almost-infinite mass and experience a drastically slowed perception of time relative to their surroundings. These once inconceivable findings had monumental implications in the sphere of theoretical physics, with two examples below. (4, 5) Dark Matter ‘Visible’, baryonic matter humanity is familiar with makes up less than a fifth of the known universe, with a hypothetical ‘dark’, non-baryonic matter comprising the rest. Dark matter lies between and within galaxies, driving baryonic matter to aggregate, forming stars and galaxies. As it cannot be detected using electromagnetic radiation, gravitational lensing provides the strongest proof of its existence. Gravitational lensing occurs when there is an interfering body between us, here on Earth, and a given target. As per Einstein’s relativity, the interfering body has mass which will bend space and therefore distort the image we receive of the target. There exists a mathematically proportional relationship between mass and distortion – the more massive an interfering body, the greater the distortion. Scientists performed calculations but found that the levels of distortion they observed correlated to masses much greater than that of the interfering body. Dark matter accounts for this invisible and undetectable missing mass. String Theory At its core, quantum physics deals with interactions at the atomic and subatomic level. This body of work has borne unusual findings – including that light can act both as a particle and wave, that we may never identify a particle’s position and momentum simultaneously with complete certainty, and that the physical properties of distant entangled particles can fundamentally be linked. On paper, however, there has been great difficulty reconciling quantum physics with relativity theory, as the former deals with interactions which occur in “jumps…with probabilistic rather than definite outcomes”. (4) String theory, however, seeks to settle this tension by proposing the universe is comprised of one-dimensional vibrating strings interacting with one another. This theoretical framework has already bore fascinating fruit – it has been hypothesised that the universe has ten dimensions (nine spatial, one temporal) and during the Big Bang, a “symmetry-breaking event” caused three spatial dimensions to break from the others resulting in an observable three-dimensional universe. (5) On 21 September 1922, astronomers in Goondiwindi, Queensland, used a total solar eclipse to successfully test and prove Einstein’s theory of relativity. Aboriginal Australians present believed they were “trying to catch the Sun in a net”. (6) Western academics were far from the only ones who sought to explain natural phenomena. From the ancient Egyptians to Japanese Shintoists and South American Incas, many civilisations of the past revered the Sun and Moon, having been enthralled by the two celestial bodies. Indigenous Australians were one such people, wanting to understand why the sun rose and set, how moon cycles and ocean tides were related, and what exactly were the rare solar and lunar eclipses. Such occurrences had a mystical property about them, reflected in a rich collection of traditional tales which looked to illuminate these astronomical observations. (7) Walu the Sun-woman Told by the Yolngu people of Arnhem Land, Walu lights a small fire every morning to mark that dawn has arrived. She paints herself with red and yellow pigment with some spilling onto the clouds to create sunrise. Walu lights a bark torch and carries it across the sky from East to West, creating daylight. Upon completing her journey, she extinguishes her torch and travels underground back to the morning camp in the East. While doing so, she provides warmth and fertility to the very Earth surrounding her. Ngalindi the Moon-man Told by the Yolngu people of Arnhem Land, “water fill[s] Ngalindi as he rises, becoming full at high tide”. (6) When full, he becomes gluttonous and decides to kill his sons because they refuse to share their food with him. His wives seek vengeance by chopping off his limbs, causing water to drain out. This is reflected by a waning moon and ebb in the tides. Eventually, Ngalindi dies for three days (New Moon) before rising once again (waxing Moon). Bahloo and Yhi Told often by the Kamilaroi people of northern New South Wales, Yhi (Sun-woman) falls in love with Bahloo (Moon-man) and tries to pursue him across the sky. However, he has no interest in Yhi and refuses her advances. Sometimes, Yhi eclipses Bahloo and tries to kill him in a fit of jealously, but the spirits holding up the sky intervene allowing Bahloo to escape. In 1788, British colonists prescribed the fictitious doctrine of terra nullius which treated land occupied by Indigenous peoples as “territory belonging to no-one,” susceptible to colonisation. (8) It is apparent, however, that Indigenous Australians did and still do belong, having a greater, more unique, and nuanced relationship to our lands and waters than we can ever hope to have. This article shows that as detailed and prescriptive our modern scientific understanding is, First Nations peoples will have an equally if not richer perspective, woven through their stories, languages, and practices. To argue that the spiritual connection Indigenous people share with country is not recognised by law would be wilfully making the same mistake our early settlers made two and a half centuries ago. It would be allowing the continuance of intergenerational trauma and suppression. For those reasons, despite the assertive legal challenges being brought against Love v Commonwealth, its judgement must be upheld. References 1.

< Back to Issue 6 Everything, Everywhere, All at Once: The Art of Decomposition by Arwen Nguyen-Ngo 28 May 2024 Edited by Subham Priya Illustrated by Jessica Walton From a single point in time, to a burst of colour and light, our universe came along into existence (The National Academy of Sciences, 2022). Within the multitude of galaxies and stars sprinkled across the universe, our little planet sits inside the solar system within the Milky Way. Like the way the universe came from a singularity, we were created from a singular cell. Over time, this cell divided and divided until we became these complex beings filled with different flavours of cells and the elements that comprise them. We are ever growing, just as the universe is ever expanding (Harvey, A., & Choi, C. Q., 2022). Though the fate of our universe is still a mystery, our fate is a little less mystical and thought-provoking – but that doesn’t make it any less interesting. Our less mystical yet fascinating fate begins with decomposition. Decomposition is the process in which dead tissue is broken down and converted into simpler forms. Large scavengers, such as vultures, foxes and crows, eat chunks of the corpse using it as a source of energy (Trees for Life, 2024). When these scavengers excrete waste — which is certainly not a pretty sight — their dung attracts smaller organisms like dung beetles. Little creepy crawlies — beetles, maggots and earthworms — all come along to the corpse, munching on its bits and pieces. They even lay their eggs in the openings of the corpse like the eyes, nose and mouth, an even LESSER pretty sight! If we zoom in further, we see microscopic bugs grow upon this dead body and take up nutrients. These bacteria then proceed with anaerobic decomposition, which occurs in the absence of oxygen. This produces gases like methane and carbon dioxide, causing the corpse to swell – the reason why dead bodies smell so bad (Trees for Life, 2024). After all that decaying, eventually, all that will remain of the carcass would be the cartilage, skin and bone, which a range of flies, beetles and parasites take advantage of (Trees for Life, 2024). Small critters such as mice and voles may come along, gnawing on the bone for calcium. How else are such little creatures supposed to get strong bones? Decomposition of dead flora is slightly different than the process for animals. For plant decomposition, fungi are the key players. When the tree leaves die and fall to the ground, they form a thick layer on the soil surface along with other dead plants, termed the litter layer (Trees for Life, 2024). Fungi have a body structure of white thread-like filaments called the hyphae, which resemble the white strings of floss. These white fungal floss take over the litter layer and consume nutrients whilst breaking down the litter layer. Unlike the decomposition of an animal, the decomposition process for plants is odourless. Phew! Over time, little wriggly earthworms begin to take control of breakdown. We use earthworms in our compost bins because they are great decomposers for dead plants and make organic fertiliser for our gardens. Whether an animal or a plant, decomposition takes each and every atom, from the carbon to the sodium atoms and recycles them to be used to create something new. It may be daunting from a human perspective to think that after all we’ve lived for, we would only be broken down and that the littlest bits of us, recycled. As our body takes its final breath, the brain fires the last of its neurons flooding our mind with bursts of colour, the way different elements cause the explosion of colours in fireworks lighting up the night sky. As the body decomposes, slowly each molecule of our body returns to the Earth, allowing for new life to take place. A sapling to sprout out from the depths of the soil. We are carried through the life of a new being; perhaps a tree, the grass or the flowers. Once again each molecule and atom in that being will return to the Earth like clockwork. And perhaps, return to the universe, a part of little sparkles that litter the night sky. References Harvey, A., & Choi, C. Q. (2022).

By Mia Horsfall < Back to Issue 3 AI and a notion of 'artificial humanity' By Mia Horsfall 10 September 2022 Edited by Breana Galea and Andrew Lim Illustrated by Matthew Duffy Next In the cradle of the day, a girl blinks to life. The sun is cool, still crouched beyond the trees, waiting for its cue to take centre-stage. Knees and knobs and spokes and all, she struggles to stand in the grass, furrowing her toes into the Earth for traction. Clean, unmarked and without memories, she looks to the sky with contentment, unaware of the work ahead. The notion of “Artificial” Intelligence is an interesting way to describe the vast and variegated mechanisms it encompasses. Not only does it pre-suppose the existence of “intelligence” within these machines, but it implies the existence of some antithetical “natural” intelligence. The term itself is a dichotomy, simultaneously alienating and connecting AI to humans. This poses some significant moral and ethical dilemmas that are becoming increasingly difficult to ignore. As the advent of AI becomes more intricately interwoven with mundane happenings, we are forced to grapple with the seemingly unanswerable question: At what point does “Artificial” Intelligence become indistinguishable from “Authentic” Intelligence? With the advent of Artificial Intelligence, public opinion surrounding the role AI should and does occupy has undergone dramatic alterations. Films and books such as “Her” (2013) and “Klara and the Sun” (2021) have explored the implications of assimilation of AI with humanity. In both pieces, AI transcends the purely utilitarian role originally defined and progresses into emotional connections with human counter-parts. It stands to reason that if these AI can enter and engage in emotionally significant relationships in the same capacity as humans, what exactly does the distinction between human and machine become? In order to define what AI is, we should first come to a conclusion of what it means to be human. So why is it so important to arrive at a definition of humanity in considering the ethics of AI inclusion in society? Well, as Hauskeller points out ‘the term ‘human’ is not primarily used to refer to a particular kind of entity...it implies a particular moral status’ (Hauskeller, 2009). That is, a subject is assigned a higher moral value in its assignment as ‘human’ and a purely physical application of the word would result in little distinction between us and other species. ‘A meaning of the word is a kind of employment of it’ (Wittgenstein, 1953), suggesting meanings and the terms to describe them are co-dependent and self-referential. Hence what it means to be ‘human’ is directly aligned with what subjects are assigned such a title. But arriving at a definition for “human” is no easy task. Philosophers and scientists have debated what constitutes the term human with little success, the definition changing across historical periods. In order to demonstrate the transient nature of the term ‘human’, a comparative analysis of definitions across historical periods provides a comprehensive overview of the dynamism that defines humankind. Hauskeller contends that any given definition of ‘human’ is ‘persuasive’. That is, each attempt ‘implicitly or explicitly claims to be of prime significance for the way we ought to lead our lives’ (Haukeller, 2009). By nature of the fact there exists multiple definitions of what characterises humanity, it can be inferred ideals of human society are themselves transient. For instance, Plato contends intelligence prevails above every aspect of human nature (White, 2013) as it is ‘the only part of himself which he does not share with the animal kingdom’ (Plato, referenced in White 2013). Whilst this definition may appear simplistic or constrictive, it is also not intrinsically wrong, merely indicative of the era in which it was formulated. Kant expounds upon the need to define ‘humanity’ asserting that any definition of an individual in isolation from a collective is futile and insufficient. Rather, it is only the ability ‘to treat himself and others according to the principle of freedom under the laws’ (Kant, referenced in Cohen, 2008) that defines humanity. In essence, it is only in relation to others that individuals may exist as human, congruent with Cohen’s assertion that ‘the study of the other is the yardstick by which men measure their own common humanity’ (Cohen, 2008). Heidegger adopts a markedly different approach in his ‘Being and time’, recognising the fluidity of human nature and creating Dasein who Oleson asserts is ‘the being of a human being, understood as the being that is concerned with being itself’ (Oleson, 2013), embodying the definition of humanity through a representation of the history of being (Oleson, 2013). Dasein exists as ‘the connection between historicality and temporality’ (Heidegger, 1927), and in this way, Heidegger seeks to define humanity by means of its instability. From these hugely variegated definitions of what constitutes the state of being human, it becomes clear we are unlikely to determine one singular, immutable definition of what it is to be human. Hence, it is difficult to have a constant point of comparison to see whether AI has “surpassed” its limits and transcended into some form of humanity. But with the increasing capabilities of AI, it stands to reason there be provisions in place in both law and politics to account not only for the implications of AI upon humanity, but for the representation of AI and its potential forms. Even if this representation or legislation is aspirational, it stands to reason there be policies in place, as various machine learning figures become more and more prominent in society and culture. At the end of the day, the girl stands cemented in her place. The line between her arms and the cogs she operates is indistinguishable amongst the black haze of smoke. In a town not too far from here, children kiss their mothers good night and fall asleep. But here, in this place, with this grime, she stands cold and unfeeling, the sky obscured by the machinery above. Previous article Next article alien back to

By Renee Papaluca < Back to Issue 3 In conversation with Paul Beuchat By Renee Papaluca 10 September 2022 Edited by Zhiyou Low and Andrew Lim Illustrated by Ravon Chew Next Paul is currently a postdoctoral teaching fellow in the Faculty of Engineering and Information Technology. In his spare time, he enjoys overnight hikes, fixing bikes, and rock climbing. Note: The following exchange has been edited and condensed. What was the ‘lightbulb moment’ that prompted you to study science? I often say that I chose engineering a little bit by not wanting to choose anything else. I think it also played into my strengths back in high school. I wasn't particularly into English, history or languages but I really enjoyed physics, chemistry and maths. So, that already drew me to science broadly. What ended up directing me towards engineering, and particularly mechanical engineering, was just always tinkering at home. My dad was always tinkering and building things. We had a garage with all of the tools necessary, and I had free rein to pull things apart and put them back together. Mechanical engineering was a way of taking a more formal route of enjoyment into the hobby. Why did you choose to pursue a research pathway? After I finished my double degrees in Science and Engineering, I got a job, which I enjoyed. It was fun working with a bigger team. In this case, it was an oil and gas company with some pretty big equipment involved. This wasn’t just tinkering with something little in the garage, but something on an industrial scale. At some stage, though, I felt like there was a bit missing. There was a research arm as part of the company, but that wasn't somewhere that I could get to. I was excited by the kind of work being done in that area, and I saw a PhD as a way of pursuing that love so that I could then work on those sorts of exciting things. What advice would you give to students considering a research pathway? Certainly, while I was a PhD, all the postdocs would say that the PhD was the best time of their life. Then the PhDs would say that the Masters was the best. So, be prepared for it to be hard. The advice is to be passionate about the topic and not be fearful about uncertainty or knowing the exact topic straightaway. Also, you likely will need a lot of support to get through the hard parts. It’s nice to have tangential input in the form of seminars, visiting academics from other institutions or even from PhDs in the same group or department. This input gives you new knowledge, new exciting fields and new industry connections. What sparked your love of teaching? My original intention was to complete my PhD, gain the relevant skills and return to the industry. My passion for teaching was sparked during my PhD experience; I got to supervise Masters students that are working on a larger project with me. It was a close collaboration with someone, where you start the process of teaching them whatever the topic is. You work on it together, and eventually, the student becomes the master. They can now guide you along, as well as having vibrant discussions together. That's what I find exciting about tertiary education more broadly - we all are pushing the limits of engineering to achieve better outcomes together. What does your day-to-day life as a teaching fellow look like? One of the focuses of my position was to include more project-based teaching, i.e. to include more hands-on education and work in the classroom, which was not included previously. I got the opportunity to create a new subject. I initially spent a lot of time developing what it was going to be. My day-to-day work included choosing new topics to add to the subject and linking them to a hands-on project, like a ground robot. There's a whole bunch of work that goes into designing a robot and the relevant software on top of preparing lecture slides and delivery—all these bits and pieces that make up a subject. Scattered throughout all this is teaching research; the teaching team assesses the students, and I need to assess the teaching itself. For instance, I need to understand what is being attempted in a particular class, what we are intending to achieve and how this aligns with the current best practices in education research publications. What advice would you give to students considering academic teaching as a career? One of the very nice things here at the University of Melbourne is the support teaching staff can receive through the Graduate Certificate of University Teaching. This gives you insight into and guidance on how to tackle the whole field. For instance, one of the lecturers mentioned that you have to be passionate about teaching because it has its ups and downs. Certainly, while developing a new subject, I found it to be quite stressful. It’s a different way of thinking, and all-new terminology, which is exciting and scary, and that took me a little bit by surprise. Where I shot myself in the foot the most was trying to do too much. I was in a very lucky position where I had free rein to make a subject as hands-on as possible, which opened the floodgates to possibilities. Prioritising was extremely important. It's not that you don’t try everything, but trying too many new exciting ideas at the same time means they probably are all going to fail or take an exorbitant amount of time to implement properly. Being realistic in my instruction was important. Also, having a mentor or someone you can talk very openly with was helpful. What are your future plans? For now, my intention is to stay in teaching. I’d like to push this position to the limits of what I can achieve and see where it takes me. I can also imagine the level of curriculum redesign in shifting whole courses to project-based learning. Current reports, like from the Council of Engineering Deans, are pushing for all engineering education to shift over to project-based learning within the next five to ten years. I’d like to continue teaching, with a view to contributing to higher-level curriculum development. Previous article Next article alien back to

She showed me the secret garden at the Bioscience Building, which was really nice. It’s fun to just explore and stuff. What is your role at OmniSci and how would you explain it to someone? I am an illustrator. I guess using visual cues and using design processes to communicate text, communicate ideas. That’s how I would describe my role, or describe what I want to do when I illustrate. What first got you interested in science? I don’t know, I think this is my attempt to reconcile both arts and science. I feel like a lot of artists try to stay in their own little circles. Like if you’re doing art you just do art. If you’re doing theatre you only know how to do theatre and you never branch out to visual art or music or even psychology… But I think it is good to have many disciplines under your belt. You don’t have to be super good at every single thing, but I guess it helps in every single thing that you do if you have knowledge about everything else. Like you can transfer skills or knowledge from one discipline to another. I think that's very valuable. That’s what got me interested in science, because I'm not doing science in school, except psychology. Back at the management university where I’m from we do more managerial psychology, like HR and marketing, we don’t really do clinical psychology. It has been interesting, because here in UniMelb I am doing a clinical psych mod, which is very very different from what I do back home. Like the topics they choose to uncover are very different. It is expanding my knowledge, my horizons. And what stage are you up to in the process now? Just reading the first drafts, so familiarising myself with them. Trying to grasp the ideas, because I think a lot of them are beyond what I’ve ever known, so trying to grasp that first. How did you get involved with OmniSci? I heard about it first at O-Week. I met you [Editor-in-Chief Caitlin] at Southbank campus, so then we talked. I was planning on joining clubs but I didn’t know what club I wanted to join. This is one of the two clubs that I joined—I also joined the Bubble Tea Society. I just wanted to do something meaningful and nice while I’m here, rather than just travelling and having fun and everything. I thought it would be nice to get to know people and talk about our ideas and see how our perspectives are different, especially because I’m so far away. And also reconciling art and science. We always highlight the differences between science and art, but I thought that OmniSci would be an amazing place to create a bridge between that. I’ve also had ideas of starting my own communications channel about psychology facts, because a lot of things that I’ve learnt at school have been very useful in my own personal life. Perhaps this way of making science accessible through art would be helpful for the general public. There are people out there who want to share and impart the knowledge that they have. I thought OmniSci might be a nice place to start doing that. What is your favourite thing about contributing at OmniSci so far? I think having the opportunity itself is the best part. It takes a lot to start a magazine on your own, so to have that platform is a big thing. The accessibility, the opportunity given to put your work out there, or have your ideas made concrete and shared with everyone. I think that’s the best thing. Low barriers of entry! Can you share something you're excited about working on this issue? Collaborating with the writers! It’s one thing to work alone and develop your ideas, and it’s another to develop them with someone else. I’m really looking forward to exploring how my style can adapt to newer themes. What do you like doing in your spare time when you're not contributing at OmniSci? I like to go to book stores, art galleries, theatre…just a bunch of arts stuff. Do you have any recommendations for theatre, anything that you’ve seen recently? I was at Malthouse Theatre a few months back, and it was really good. I really recommend Malthouse. There’s a State Library Exhibition on fringe festivals in Australia . I really believe in fringe stuff, so I think that’s a really thought-provoking exhibition to reflect on what we define as “good” and “bad” art. I also went to watch Patroclus and Achilles at the UniMelb Shakespeare company. It’s important to support student theatre because that’s where future artists start out! Which chemical element would you name your firstborn child (or pet) after? Oh my god, it’s so painful…I’m going to go with Potassium, so I can nickname them K. I’ll call them K all the time, except when I’m mad—then I’ll call them Potassium. See Jolin's designs PT PT Real Life Replicants
