< Back to Issue 4 Echidnas: Gentle Courters In The Competitive Animal Kingdom by Emily Siwing Xia 1 July 2023 Edited by Maddison Moore and Arwen Nguyen-Ngo Illustrated by Christy Yung When we think of animals or nature in competition, we picture aggression and savagery over resources such as food, territory and mates. Beyond aggression, however, the variety of animal behaviour associated with competition for resources is immense. A gentle form of competition is the bizarre mating ritual of our own unique Australian fauna: the echidna. Known as Tachyglossus Aculeatus and spiny anteaters, echidnas are quill-covered animals living in Australia and New Guinea. Since Australia is so isolated from other continents, our fauna has often been regarded by outsiders with an air of mystery and awe. To start with, echidnas are in the same family as the famed platypus, called monotremes (egg-laying mammals). Surviving monotreme species can only be found in Australia and New Guinea. The four species of echidnas, along with their duck-billed cousin, are the very few surviving members in this classification. Despite the similarities in their name and appearance in both being covered with hollow, spiny quills, these spiny anteaters are not actually closely related to the more well-known anteaters in the Americas on a genetic and evolutionary basis. Echidnas feed on a diet of ants and termites, using their electroreceptive beaks to find burrowing prey digging them out with their hind claws. These powerful claws are long and curved backwards, specially designed for digging. Funnily, when the British Museum received an echidna specimen, they switched the backward claws frontwards thinking that it was a mistake. As mentioned before, mating rituals can be a violent (even bloody) ordeal in nature. From barbed penises in cats and deadly fights for females in elephant seals, straight to sexual cannibalism in praying mantises, there seems to be endless examples of brutality in the animal world. However, behind these brutal images is another side of nature that seems gentle and even humorous at times: for example, the ritual of our spiny suitors. Echidna mating rituals begin with the formation of a mating train. From June to September in Australia, male echidnas mate by lining up — from their beak tips to their spiny bottoms — to follow behind one single female. These trains can have more than 10 males in line and last for days, even weeks, at a time. During the mating season, male echidnas may leave a train to join or form a different train behind another eligible female. Their mating efforts often lead males to travel for long distances, even beyond their own home ranges. If the males get interrupted and lose track of the female, they reform their train by picking up her scent with their snouts in the air. They are such determined suitors that it is extremely difficult for a female echidna to evade them. Usually, there is one male that remains through the long-winded process, and they get to mate with the female. The reason behind forming echidna trains is unknown, but scientists generally agree that it is correlated with some type of selection process. One theory is that it aids the female in weeding out all the weaker males by tiring them out until the last one remains. Another is that the female is waiting for the right male that she is interested in to get behind her. Either way, it is a process of determination and perseverance. In exceedingly rare occasions where there are still multiple suitors left at the end, the males dig a trench surrounding the female and compete through head bumping. Although there is still much not understood about head bumping due to its scarce occurrence, it is generally considered an echidna social behaviour that serves to maintain dominance. Head bumps are generally only given by dominant echidnas to subordinate echidnas who haven’t recognised their dominance status and moved away. This rarely happens and is a relatively peaceful affair compared to conflicts in other animals. The winner of the mating head bumping ritual then digs until the previously mentioned trench is deep enough for him to be below the female so they can mate through their cloacas. 23 days after copulation, the female lays a soft-shelled leathery egg into a temporary pouch where it continues to incubate for 10 more days when a tiny puggle (a baby echidna or platypus) hatches. The puggle drinks milk from the female’s special mammary hairs until it is capable of feeding itself and has fully covered spines and fur. At last, the matured echidna leaves their mother’s burrow to live independently. The mating rules and practices amongst echidnas are a demonstration of patience and courtesy. This contrasts with the general public misconception of nature being merciless, which is characterised by the brutal competition for food, social status and mating opportunities. Although they are in the same competition for a mate, the lines of waddling echidnas are polite, organised and humorous. Behind the mask of brutality, nature continues to have its pleasant secrets.

< Back to Issue 5 A Message from the Editors in Chief Rachel Ko & Ingrid Sefton 24 October 2023 Edited by Committee Illustrated by Aisyah Mohammad Sulhanuddin “There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know.” - Donald Rumsfeld Science should never be considered as pursuing absolute truth. In fact, more often than not, the deeper we dive into its exploration, the more questions that arise. The world of science affords us choices in how we appropriate the understandings and knowledge gained in its study. Every day, science pushes us to tiptoe this fine line between pushing boundaries and crossing them altogether. It is perhaps this unknown that makes the pursuit of science so wicked in itself, taunting us with the promise of making the next big discovery, or finally finding the cure to cancer. But it is also what drives us, entrances us, and keeps our desire for knowledge burning — it’s edge-of-your-seat exciting. At its onset, we envisioned this issue as a chance to probe the mysterious nuances of science — a peek into the ‘Wicked’ness of the world. Seeking to ask questions of the ethical, the malicious and the unknown, contributors were inspired to delve into the darker sides of science. Each article ventures into the limits of what we do, and, just as importantly, don’t know in this ever-evolving field. The word Wicked in itself is a complex character, begging for ambiguous interpretation. Is there such a thing as pure evil? Are we all, just a bit, inherently wicked? What makes something wickedly cool? (Was Kristin Chenoweth’s Glinda the best portrayal that Broadway could ask for?) And so, in the hands of our creators, something wicked this way comes … As with every edition of our magazine, each piece has been created, edited and illustrated entirely by students. This issue continues to stand true to our aim of providing a platform within, and beyond, the university community for students of all backgrounds to craft their science communication skills in a supportive, creative environment. Countless hours have been poured into the curation of each edition with the hope of making innovative science content easily accessible — so please, enjoy! To all our passionate, dedicated contributors - thank you for the time you have invested in crafting the wonderful, wicked world of Issue 5 of OmniSci. It has been a privilege to watch the collaboration of inquisitive minds, from diverse scientific and artistic worlds, produce this collection of work. We also wish to extend our gratitude to you, our wonderful readers, in your ongoing support of OmniSci. The time you give to reading and engaging with our student-driven magazine does not go unnoticed, motivating and inspiring us for our future endeavours. Now, take a moment, and come venture into the Wicked world of Issue 5 with us… Wicked back to

< Back to Issue 2 How to use a time machine Whilst time travel is thought to be nothing more than science fiction, the very laws of physics point to its possibility. Physicists have long sought the answer to such a phenomenon using knowledge from rockets to generating wormholes. by Sabine Elias 10 December 2021 Edited by Niesha Baker Illustrated by Quynh Anh Nguyen So you have just entered the TARDIS machine and are trying to work out how to use it to travel to the past to re-write the present and save the future? Well, look no further because you have come to right place. In this article, I will be describing how to jumpstart your time traveling vehicle and by the end, you will be proficient in navigating your way through the universe and evading time. Do be warned however, that batteries are not included and the simulation may crash at times. Now, you are probably wishing that you could travel back in time to have not clicked this article and saved yourself these two minutes of life that you will never get back. But is time travel really a possibility? We often think about the world as a state of order. Social and political constructs generally keep society running in a systematic manner. But what if I told you the entire universe came to exist from disorder? Before we get to logistics, let me introduce you to a little something known as ‘entropy’. Entropy describes the state of disorder (1). Take a closed bottle containing gas. Once you open this bottle, the gas will diffuse out into the open space with no way to retrieve it in the exact same state back inside the bottle. In essence, this gas has become ‘disordered’ and thus its entropy has increased. For years, scientists have understood that the entropy of the universe is always increasing, which means that stars, planets and galaxies are in constant motion away from each other (1). If we wanted to travel back in time, we would essentially have to reverse every single chemical reaction that has occurred from the point in time we currently stand in, to the point in time that we wish to travel to (2). This is theoretically impossible as we would be violating the laws of physics and decreasing the entropy of the universe but we still do not know if it is physically impossible. Let Brain Cox explain: Another problem with time travel would be altering events of the past. Take the Grandfather Paradox: if someone travelled back in time to kill their ancestor, then the possibility of their existence in the future would be zero (3). Thus, they would have been unable to time travel to begin with to have killed their ancestor. This issue of causality is expanded upon through the Novikov Self-Consistency Principle (4). This states that if an event causes a paradox or changes the past, the possibility of this event occurring would be impossible. However, this principle is not widely accepted by time travel enthusiasts. Now, whilst your TARDIS machine may be nothing but a prop at this point in time, it could still help provide evidence on the possibility of time travel. Take this example: you set up two duplicates of the same clock that read the same time and placed one into a rocket that blasts off into space. The rocket orbits around the Earth and then returns and is compared to the clock that remained on Earth. You would find that less time has passed on the clock that was in the rocket. Why? Because moving clocks run slower than stationary clocks. That is, as you move faster through space, you move slower through time. This is known as Time Dilation (5). An example of time dilation is the comparison of time on the International Space Station (ISS) to the time on Earth. Astronauts who have spent 6 months in the ISS have aged 0.005 seconds less than people on Earth (6). This does not seem like much because the astronauts are not traveling close to the speed of light. To see the effects of time dilation multiply, one would need to be very close to the speed of light. If you were to travel in space at 90 per cent the speed of light, whilst everyone on earth would age by 22 years you would only have aged by 9! Speed is not the only thing that affects how fast we age, gravity also affects our experience of time. A stronger gravitational field means that time travels slower in that field. For instance, your feet age slower than your head considering the slightly smaller gravitational pull on your feet compared to your head. Now take a black hole; we know that black holes have immensely strong gravitational fields where one hour near a black hole would equal approximately 100,000,000 years for a person on earth (7). So what would happen if you travelled through a black hole? No one really knows what occurs inside a black hole but we know trying to enter will likely turn you into spaghetti (8). That being said, we can only observe things that go as far as the event horizon of the black hole, so once something has entered it, we do not know what has happened. Black holes have however, been especially useful in theoretically explaining the possibility of time travel. Placing someone in a strong gravitational field or having them experience motions close to the speed of light would have them experience time slower compared to someone on Earth. This brings us to wormholes. Einstein’s theory of general relativity predicts the existence of wormholes which would theoretically permit time travel. To travel to a galaxy that is 2.5 million light years away with the fastest rocket on earth would be impossible as it would take longer than a human lifetime. This is where wormholes come to the rescue. A wormhole would provide us with a shortcut to our location of interest. Imagine folding a paper in half and poking a pen through it to represent your route of travel. You are essentially skipping the length of the paper and traveling from one end to the other. Source: The Independent. (2008). The Big Question: Is time travel possible, and is there any chance (9). You then situate one mouth of the wormhole in a spacecraft traveling close to the speed of light and the other mouth on Earth. If you then went through the mouth on Earth and travelled through to the space craft, you would be traveling back in time. This is because time would be passing much slower at the other end of the wormhole than where you entered from. However, physicists have not yet developed such advanced technology capable of this, but theoretically speaking, this is a possibility if such technology was developed in the future. Whilst you may have thought that time travel was merely based on science fiction, the laws of physics do not forbid its existence. However, here is some food for thought: “If time travel is possible, where are the tourists from the future?” Stephen Hawking Perhaps with time, we may transform this theory into reality. So for the time being, just sit back and enjoy the presence of your TARDIS machine. Perhaps you might even get lost in time from the very thought of time travel. References: 1.

< Back to Issue 9 Rewilding Our Cities with Dr Kylie Soanes by Ciara Dahl 28 October 2025 Illustrated by Jess Walton Edited by Arwen Nguyen-Ngo When you think of nature, I bet the last things that come to mind are skyscrapers, freeways and footpaths. Welcome to the hidden world of urban ecology! I recently spoke to urban ecologist and prolific science communicator Dr Kylie Soanes about the challenges of conserving wildlife in urban environments, and what drives her to protect nature in our cities. Dr Kylie Soanes is determined to protect wildlife in our urban environments. (1) A research fellow at the University of Melbourne, Soanes describes herself as “your friendly neighbourhood wildlife scientist” on a mission to “save nature in cities and towns.” Her projects range from designing rope bridges to help endangered possums cross busy roads, to installing floating wetlands that bring biodiversity back to our urban waterways. Cities are a bustling weave of people and places, but where does nature belong in all of that chaos? That’s the question Soanes has dedicated much of her career to exploring. Like many of us, she grew up in a classic urban environment, longing to get into the wild. Her passion for learning about the natural world eventually grew into a career studying ecology and conservation at university. There is a common assumption that nature doesn't belong in cities. However, Soanes emphasises that cities are a “perfect place for people to connect with nature; there’s heaps of amazing biodiversity here”, adding that “it doesn't always have to look like the pristine natural conditions for it to be valuable”. She emphasises that communicating this message is the "first real step" in shifting mindsets. Soanes notes that urban ecology is often more about working with people than with science, explaining that “there are still people in this space that need to use it." Urban ecologists must be skilled collaborators, working with communities and experts across disciplines – from architects and engineers, to social scientists and artists – to reach solutions that balance the needs of nature and people. But what happens when communities don't feel seen by urban plans? A recent effort to protect swamp wallaby habitat along the Merri Creek Trail by diverting pedestrian traffic was met with concern from the community about personal safety (2). Cases like these highlight the challenges urban ecologists face every day when trying to make space for nature in our cities. Soanes argues that it is critical for urban ecologists to discuss “social risks and social justice, to make sure that we're not changing cities in a way that makes it worse for people". Public outcries like these often stem from communities that are faced with “a decision that they think that they weren't involved in”. The biggest tool in an urban ecologist's belt is community consultation, "so that everybody is brought along on the journey and we can make the right call for everyone." Some of Soanes’ favourite work is not just about protecting nature in cities, but putting it back. She speaks about creating new habitats in urban spaces, such as floating wetlands that transform bleak industrial wastelands into thriving ecosystems, or even rooftop gardens that reclaim space for nature. One of the most exciting areas of urban ecology includes restoring locally extinct species. Soanes cites the example of the endangered Key’s Matchstick Grasshopper, which was reintroduced to Royal Park in 2022 to restore the local population and support a healthy ecosystem (3). Often, such projects are overlooked in urban areas. She explains how they are frequently “put in the too hard basket”; but there is now a shift in focus towards “physically reintroducing species once we know that all the things that they need are there". So, where can we find some of Melbourne’s most exciting urban ecology projects? You can spot the floating wetlands in various locations along the Yarra River (4), and native wildflower meadows planted on roadsides throughout the city (5). Ever spotted those wooden boxes on trees around Melbourne’s gardens? They’re not decorations – they’re artificial hollows providing safe places for wildlife to nest (6). Additionally, “lots of councils are really embracing water sensitive urban design" by installing "miniature wetlands that slow rainwater down and clean it up before it hits our stormwater system" (7). The City of Melbourne has installed floating wetlands in the Yarra River since 2022. (4) Soanes also emphasises how cultural values and knowledge can be woven into urban ecology projects. She points to the revitalised Moonee Ponds Creek as an example, noting “it has a calendar for the Wurundjeri seasons and a beautiful cultural trail.” Projects like these offer valuable opportunities for communities to connect not only with nature, but with culture. So, how can we make our own homes more wildlife-friendly? Soanes encourages asking, “What can I add to make living here easier for species other than me? ”. It could be as simple as planting a few more native plants in your garden. As the warmer months approach, placing birdbaths or shallow water trays outside can help wildlife keep cool, “especially as our cities become hotter and drier”. Outside of her work as a researcher, Soanes has a strong social media presence, using it as a platform to share her conservation messages with the wider public. She emphasises that science communication is "about making your messages and your science accessible not just to the broader public, but to the people making decisions". Dr Kylie Soanes platforms her conservation messages on social media. (8) Soanes argues that "showcasing and celebrating those stories of success" gives people "hope that they can make change in their area", while inspiring councils and urban land managers to apply similar solutions. She acknowledges that wildlife conservation can feel "very heavy” at times but stresses “it is important to show that there are all these options out there.” "There are so many other people that want the same things, or would like to see their neighbourhood become a little bit better for nature," she adds. "I think almost everybody cares about nature – it just doesn't always look like wearing khaki and carrying binoculars at all times." A big thank you to Dr Kylie Soanes for taking the time to speak with us and shed light on the fascinating world of urban ecology.

< Back to Issue 6 Proprioception: Our Invisible Sixth Sense by Ingrid Sefton 28 May 2024 Edited by Subham Priya Illustrated by Jessica Walton What might constitute a sixth sense? Perhaps, it involves possessing a second sight or superhuman abilities. A classic example of this would be Spider-Man and his ‘spidey-sense’ — an instinctual warning system that alerts him to imminent danger. Enhancing his reflexes and agility, his sixth sense enables him to evade threats with precision. Turns out Spider-Man is not the sole bearer of a ‘spidey sense’. While we may not be scaling walls anytime soon, we too possess a special sense that unconsciously guides our movements. It might sound peculiar, but knowing your arm is indeed your own arm involves a unique form of sensory processing. Considered by neuroscientists as our own ‘sixth sense’, proprioception is our own way of helping the brain to understand the position of our body and limbs in space (Sherrington, 1907). Consider a typical scenario: your first sip of coffee in the morning. Eyes shut, you savour your latte before the day begins. Such a simple act, yet impossible without proprioception. With closed eyes, how do you know where your mouth is? How do you gauge the position of your arm to ensure the coffee cup reaches your lips? Proprioception seamlessly transmits information about muscle tension, joint position, and force to the brain, making drinking your coffee an automatic and coordinated process. Proprioception operates on principles akin to those guiding our other senses. Specialised cells, known as receptors, are found in each sensory organ and receive information from the environment. Receptors in your eyes capture visual information, while those in your ears detect auditory stimuli. This sensory information is transduced through signals to the central nervous system – through the spinal cord and to the brain – where it’s integrated and processed to determine an appropriate response. Analogously, proprioceptive information is mediated by proprioceptors, a unique type of receptors located in your muscles and joints (Proske & Gandevia, 2012). Unlike our other senses, proprioception does not rely on input from the external environment. Rather, it provides feedback to the brain about what the body itself is doing. Changes in muscle tension and the position of our joints are relayed to the brain, ensuring awareness of the body’s whereabouts at any given moment. One implication of this ‘internal’ feedback loop is that proprioception never turns ‘off’. When you cover your ears, you experience silence. If you hold your nose, you can block out the smell. Yet even when still, in motion, or unconscious, your brain continuously receives proprioceptive input. Imagine this in the context of going to bed each night. What exactly prevents you from falling out of bed, once asleep? While most senses are subdued when sleeping, proprioception remains active, informing the brain about the slightest changes in the position of the body. This ensures a perpetual awareness of our body in space – and luckily for us, stops us from rolling out of bed (Proske & Gandevia, 2012). It can be hard to appreciate what our proprioceptive system allows us to do, given its unconscious nature and integration with our other senses. Rare neurological disorders affecting proprioception highlight just how critical this sense is in our daily lives. The case of Ian Waterman – now known as ‘the man who lost his body – offers profound insights into the significance of proprioception (McNeill et al., 2009). Following a fever in 1971 at age 19, a subsequent auto-immune reaction destroyed all his sensory neurons from the neck down–a condition termed ‘neuronopathy’. Despite retaining his intact motor functions, Waterman lost all proprioceptive abilities, rendering him unaware of his body's position in space. Although the viral infection’s initial effect was that of immobility, this loss was not due to paralysis. Rather, it was Waterman’s lack of control over his body that inhibited his ability to move. Sitting, walking, and manipulating objects became impossible tasks as a result of the absence of any proprioceptive feedback from the body. Remarkably, Waterman has been able to teach himself precise strategies to walk and function with a degree of normality (Swain, 2017). Yet, all movement requires concerted planning and relies entirely on vision to compensate for the unconscious proprioceptive processing. In the absence of any light, Waterman is unable to see his limbs, thus restricting his ability to move. An understanding of the molecular mechanisms underlying proprioception remains somewhat of a mystery compared to that of our other senses. However, recent genetic advancements are paving the way for the development of novel therapies aimed at neurological and musculoskeletal disorders (Woo et al., 2015). A study involving two young patients with unique neurological disorders affecting their body awareness revealed a mutation in their PIEZO2 gene (Chesler et al., 2016). Both individuals experienced significant challenges with balance and movement, coupled with progressive scoliosis and deformities in the hips, fingers, and feet. The PIEZO2 gene typically encodes a type of mechanosensitive protein in cells, r esponsible for generating electrical signals in response to alterations in cell shape (Coste et al., 2010). Mutations to this gene prevent signal generation and render the neurons incapable of detecting limb or body movement. These findings firmly establish PIEZO2 as a critical gene for facilitating proprioception in humans, a sense that is crucial for bodily awareness. PIEZO2 mutations have also been implicated in genetic musculoskeletal disorders (Coste et al., 2010). Joint problems and scoliosis experienced by the patients in a study suggest that proprioception may also indirectly guide skeletal development. These insights into the role of the PIEZO2 gene in proprioception and musculoskeletal development open up promising avenues for understanding and treating neurological and musculoskeletal disorders. It’s more than fitting to regard proprioception as our sixth sense. The capacity of our nervous system to seamlessly process vast amounts of information from our joints and muscles, all without any conscious effort on our part, is truly remarkable. So, the next time you have that eyes-shut first sip of coffee, give yourself a pat on the back. With your sixth sense at play, you’re clearly a superhero! References Chesler, A.

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.

By Yvette Marris Behind the Mask By Yvette Marris 23 March 2022 Edited by Tanya Kovacevic Illustrated by Quynh Anh Nguyen It would be hard to write about A Year in Science without the obligatory COVID article. We hear constantly about the stresses of being a frontline healthcare worker, the signs and symptoms of long COVID, and the endless vaccine scepticism. I’d like to tell a slightly different story. During the COVID pandemic, other infections didn’t just take a holiday and cancers didn’t just stop growing. More ordinary illness and injury continued behind the headlines. As a consequence of the pandemic, healthcare workers are additionally dealing with an abundance of patients, delays with diagnosis and some very complex medical cases. Megan Gifford worked in a hospital that didn’t primarily treat COVID-19 patients, but still had to adapt to the constant changing of rules, regulations and policies put in place to protect staff and patients alike from the virus. Now at the Peter MacCallum Cancer Centre in Melbourne, Gifford spoke to me about her experiences working at Townsville University Hospital in the only bone marrow transplant ward servicing a large population across regional Queensland. Gifford experienced the stress and burden of trying, not only to assuage their own anxieties but to also provide current, up-to-date information to patients and deliver high quality care. There were the frustrations of unavoidable logistical problems like border closures, stay-at-home orders, preventing access to crucial materials and patient transport. There was heartbreak of watching transplant patients deteriorate mentally, as their will to persist with treatments began to fade. Pathologists and haematologists also found themselves facing an unprecedented logistical nightmare, including re-allocation of diagnostic equipment and protective equipment for mass COVID testing. Access to essential biomedical material like blood and plasma became increasingly difficult and many suffered as a result. While pandemic consequences like long COVID and the increased prevalence of affective disorders, like depression and anxiety, are well documented in media and academia, post-traumatic stress disorder (PTSD) hasn’t gotten the same amount of attention. Statistics and anecdotes alike are staggering, both for patients and healthcare workers. With stressors like an unprecedented number of critically ill patients, capricious disease progressions, high mortality, and ever-changing treatment guidelines the world was sympathetic to healthcare workers’ struggles (3). Yet with the lockdowns and restrictions over, it would be naïve to think everything would just return to normal. It was found that 29% of healthcare workers had clinical or sub-clinical symptoms of PTSD (1), and that this figure was significantly higher for healthcare workers directly treating COVID patients (2). Gifford recalled anecdotes of “patients suffering anxiety attacks when they smell the hospital alcohol rub and hear the familiar beeping of the various equipment”. Even beyond the mental health scope, logistical issues like delayed learning for medical students or the backlog of elective procedures is still placing an enormous burden on healthcare workers, despite the immediate threat seemingly behind us. But to say that everything remains in shambles would frankly be insulting to healthcare workers, who are working tirelessly to deliver good quality healthcare. The speed at which pathologists and scientists have adapted to limited resources and supply shortages, and the way in which doctors and frontline workers have shifted their style of care and developed new problem-solving skills, are exceptional and should not go unnoticed or unappreciated. Importantly, the COVID-19 pandemic and its ripple effects have brought centre stage the consequences of under-resourced healthcare centres in a way that affected all people, irrespective of geography, class or reputation. The reality is that the conditions in which many metropolitan hospitals found themselves in, with never enough staff or supplies, is a condition that some hospitals experienced long before COVID-19 ever appeared, particularly in rural settings. To say that every dark cloud has a silver lining would be horribly cliché, but in this case, there may be truth to it. This edition of A Year in Science is a chance for us to reflect on all that COVID-19 has called attention to and decide to do something about it.

< Back to Issue 7 Fossil Markets: Under the Gavel, Under Scrutiny by Jesse Allen 22 October 2024 edited by Zeinab Jishi illustrated by Jessica Walton At the crossroads between science and commerce, the trade in fossils has "developed into an organised enterprise" over the course of the twentieth century. With greater investment and heated competition between museums and private collectors, fossils increasingly took their place alongside “art, furniture, and fine wine” (Kjærgaard, 2012, pp.340-344). Fast forward to the twenty-first century, and this trend shows no signs of abating. On the contrary: as of 10 July 2024, a near-complete stegosaurus skeleton - nicknamed ‘Apex’ - was discovered by a commercial palaeontologist in Colorado, and was later purchased by “hedge-fund billionaire” Ken Griffin for US$44.6 million (Paul, 2024). This makes it the single most expensive dinosaur skeleton ever sold, eclipsing the previous record set in 2020 for a T-Rex named ‘Stan’, who was snapped up for US$31.8 million (Paul, 2024). These sales came with their fair share of criticism and controversy, reigniting the long-standing debate about how fossils should be handled, and where these ancient remains rightfully belong. Fossils (from the Latin fossilus , meaning ‘unearthed’) are the “preserved remains of plants and animals” which have been buried in sediments or preserved underneath ancient bodies of water, and offer unique insights into the history and adaptive evolution of life on Earth (British Geological Survey, n.d.). Their value is by no means limited to biology, however: they are useful for geologists in correlating the age of different rock layers (British Geological Survey, n.d.), and reveal the nature and consequences of changes in Earth’s climate (National Park Service, n.d.). Though new discoveries are being made all the time, fossils are inherently a finite resource, which cannot be replaced. This is part of what makes the fossil trade so lucrative, but the forces of limited supply and high demand have also led to the emergence of a dark underbelly. Cases of fossil forgery go back “as far as the dawn of palaeontology itself” in the late 18th and 19th centuries (Benton, 2024). The latest “boom in interest" is massively inflating prices and “fuelling the illicit trade” in fossils (Timmins, 2019). Whereas the US has a ‘finders-keepers’ policy, according to which private traders have carte blanche to dig up and sell any fossils they find, countries such as Brazil, China, and Mongolia do not allow the export of specimens overseas (Timmins, 2019). Sadly, this does little to prevent illegal smuggling; the laws are sometimes vague, and enforcement can be difficult when no single government agency is responsible for monitoring palaeontological activities (Winters, 2024). According to David Hone, a reader in zoology at Queen Mary University of London, “not every fossil is scientifically valuable”; but they are all “objects…worthy of protection,” and too many “scientifically important fossils appear briefly on the auction house website” before “vanish[ing] into a collector’s house, never to be seen again” (Hone, 2024). Museums, universities, and other scientific organisations are finding it more and more difficult to “financially compete with wealthy, private purchasers” as they are simply being priced out of the market (Paul, 2024). As sales become less open to expert scrutiny, the risk of forgery and price distortions become greater. It also has negative implications for future research. Private collectors might give access to one scientist, but not allow others to corroborate their findings. If the fossils aren’t open to all, many institutions simply won’t examine the items in private collections as a matter of principle. (Timmins, 2019). The general public also loses out in a world where dinosaur fossils are reduced to expensive conversation pieces. As Hone writes, “we might never dig up another Stegosaurus, or never find one nearly as complete as [Apex].” Having waited 150 million years to be unearthed, this latest fossil is one of many that may not see the light of day for a very long time.
