< Back to Issue 3 Space exploration in Antartica By Ashleigh Hallinan 10 September 2022 Edited by Tanya Kovacevic and Breana Galea Illustrated by Aisyah Mohammad Sulhanuddin Next The isolated southern expanse of the Earth is an alien realm, with vast expanses of white ice and blue sky that appear to stretch on infinitely. Despite its barren landscape, the Antarctic continent holds secrets to the origins of our Earth and the solar system in the form of meteorites. Meteorites are solid pieces of debris that originate in outer space, survive the journey through our atmosphere, and fall to the Earth’s surface.(1) Their unique components and pungent smells contain fascinating stories of cosmic clouds, condensing stardust and the fiery collisions of entire planets. These ‘space rocks’ can land anywhere on Earth, but the vast majority of meteorites are found in the cold deserts of Antarctica.(2) So, why Antarctica? Across the globe, meteorite abundance is dependent on two factors: the meteorites must be easy to spot, and their preservation must be guaranteed over long time periods.(3) It is the conditions of the Antarctic landscape that make all the difference when it comes to meteorite discovery. The cold, dry nature of Antarctica helps to preserve these extraterrestrial rocks, allowing for more pristine samples to be collected. In this way, we may think of Antarctica as a ‘natural freezer’. In fact, meteorites can be buried and preserved in the Antarctic ice for up to millions of years, allowing for a deep dive into the origins of the solar system upon analysis. Furthermore, meteorites are easier to find in Antarctica due to the stark contrast between the dark colours of meteorites and the white ice. And since so few rocks naturally form on ice sheets, you can be fairly certain the majority of rocks found in Antarctica are extraterrestrial. However, an expedition to Antarctica for meteorite hunting is no small feat. Thankfully, landscape processes occurring on the Antarctic continent create concentrated pockets of meteorites, making the hunt for meteorites less like trying to find a needle in a haystack. These meteorite hotspots are largely a result of the local geology and movement of ice across the Antarctic landscape.(4) As meteorites strike glaciers, they are buried and encased in the ice. These glaciers move across the landscape, acting as ‘conveyor belts’ that carry the meteorites until they reach a large barrier, such as the Transantarctic Mountains. The ice flow is blocked and builds up at the base of the mountain. Here, dry Antarctic winds slowly erode the ice, revealing a bounty of imprisoned meteorites. Traditionally, meteorites have been divided into three broad categories: stony, stony-iron, and iron.(5) While stony meteorites are made up of silicate minerals, iron meteorites are almost completely made of metal. Unsurprisingly, stony-iron meteorites are composed of nearly equal amounts of metal and silicate crystals. Alarmingly, warmer temperatures and melting ice associated with global warming may hinder our search for meteorites. This is particularly the case for iron meteorites, which conduct heat more efficiently than other meteorite types due to their higher metal content.(6) Consequently, meteorites can sink into the ice and out of sight. Despite Antarctica’s otherworldliness, it is not free of the impacts brought about by human activity occurring on landmasses separated by vast seas. However, with the help of artificial intelligence and machine-learning, the quest for meteorite discovery continues. Scientists recently estimated there are as many as 300,000 more meteorites to be discovered in Antarctica, their stories waiting to be uncovered in a never-ending game of hide-and-seek.(7) Using machine learning to combine satellite measurements of temperature, surface slope, speed of ice flow, and reflection of radar signals by ice, scientists have developed a ‘treasure map’ containing the predicted locations of concentrated meteorite zones.(7) The ’treasure map’ is accessible online,(8) so anyone can search the Antarctic continent for rocky remnants left over from the formation of the solar system. When we think of space exploration, we conjure up images of astronauts and spaceships. But Antarctica provides us with the opportunity to peer into the cosmos without ever leaving Earth, given we are brave enough to face the inhospitable conditions and pervasive alienness of the Earth’s southernmost continent.

< Back to Issue 5 When Dark Matters Ingrid Sefton 24 October 2023 Edited by Celia Quinn Illustrated by Louise Cen To put it simply, the entire visible universe is huge. In the scheme of it, we really are just tiny dots on a floating rock, in a vast and constantly expanding cosmos. Yet, as it turns out, that’s not even close to the full story. All the visible objects, planets and galaxies contribute less than 15% of the mass in the universe. The other 85%? Nobody knows for certain, but it has a name. Dark matter. More can be said about what dark matter is not, than what it is. It isn’t the baryonic or “normal” matter such as protons, neutrons and electrons which comprise our visible world. It also isn’t antimatter, composed of subatomic particles with opposite charges to normal matter. Instead, dark matter interacts with normal matter in a manner entirely different to that of antimatter. It’s not a type of black hole, nor simply a form of radiation, or a type of massless particle. So, what can be conclusively said? Essentially, nothing. As the name suggests, dark matter emits no light and therefore is not visible in the way normal matter is, making it difficult to observe. In fact, dark matter has only been “observed” by way of its gravitational effects. Therefore, we know it must have mass in order to be able to interact with visible matter gravitationally. It’s also imperative for it to be big enough to cause the massive gravitational effects seen in galaxies (Lochner et al., 2005). Estimates place the mass-energy content of the cosmos as being composed of 26.8% dark matter, 68.3% dark energy and a relatively miniscule 4.9% normal matter (Greicius, 2013). The terms dark matter and dark energy are often thrown around somewhat interchangeably. However, they explain distinct aspects of observed gravitational and physical phenomena. Dark matter can be thought of as an invisible substance which is only seen through its effects on gravity - the unexplained gravitational forces that hold together rapidly rotating galaxies and stopping them from flying apart. Dark energy is then the force responsible for pushing these clusters of galaxies and the universe apart, accelerating the rate of expansion of the universe (NASA/WMAP Science Team, 2013). Given the lack of answers about what dark matter is, an interesting question to ponder is how its existence was even discovered. Swiss astronomer Fritz Zwicky was the first to propose the idea of “dark matter”. His observations of the Cloma galaxy cluster led him to suggest if individual galaxies within the cluster were only held together by the gravitational force of visible mass, the galaxies should fly apart due to their high velocity (American Museum of Natural History, 2000). He termed this mysterious force responsible for binding galaxy clusters together “dark matter”. It wasn’t until the 1970s that Vera Rubin became the first person to establish the existence of dark matter through her work with spiral galaxies. Spiral galaxies aren’t stationary. They rotate, with stars different distances from the centre moving in roughly circular orbits around this centre. The highest concentration of visible stars is found within the core region of a galaxy, leading to the assumption that the majority of mass, and therefore gravity, should also be concentrated there. An implication of this is the expectation that the farther a star is from this gravitational centre of a galaxy, the slower its projected orbital speed should be (American Museum of Natural History, 2000). However, alongside astronomer Kent Ford, Rubin made the puzzling observation that stars in both the centre and outer regions of any galaxy were moving at the same speed (American Museum of Natural History, 2000). Her calculations provided convincing observational evidence of Zwicky’s theory. The presence of a significant mass of invisible matter in the outer regions of a galaxy would create an even, spherical distribution of matter, gravitationally explaining the observed rotation of galaxies and their velocity distribution (NASA/WMAP Science Team, 2013). Fifty years later and experimental evidence still remains the only “proof” of dark matter we have, having been unable to directly detect dark matter. Despite this, a majority of scientists are confident in its existence. Rubin’s insight into the velocity distribution of galaxy rotation curves is amongst some of the most convincing observational evidence for the presence of dark matter. Also supporting its existence are the various discrepancies that arise in the process of gravitational lensing. Gravitational lensing occurs when an emitted source of light is deflected or distorted by the gravitational field of a large mass. Based upon the degree of deflection, the gravitational potential of the object can be calculated, alongside the amount of matter in the lensing object (Xenon Dark Matter Project, 2022). Yet, the strength of this gravitational lensing observed in many galaxy clusters is significantly greater than that calculated from visible matter alone. These inconsistencies point to the existence of unseen mass, or dark matter, as a convincing explanation for the observed lensing effects. It’s become clear that the standard model of physics, explaining the different particles and forces comprising the visible world, cannot be used in attempting to explain dark matter. In response, researchers are exploring a number of avenues to find hypothetical new particles. Amongst the most likely candidates for the composition of dark matter are two classes of particles: Weakly Interacting Massive Particles (WIMPs) and axions. WIMPs are distinguished as a class of particles created thermally in the early universe at very high temperatures, while axions originate predominantly from non-thermal mechanisms (Griest, 2002). Compared to WIMPS, or other known type of particles, axions would be thousands of times lighter but also significantly more abundant than WIMPs (Darling & Knight, 2022). Given the infinite potential to invent hypothetical substances that resolve the enigma of dark matter, experimentation to find these particles has significant challenges. Current research efforts are focused on the detection of such particles. More than a kilometre underground in Stawell, Victoria, the Stawell Gold Mine has been converted into an underground laboratory – one with no light, no noise, and no radioactivity to interfere with dark matter signals (Lippincott, 2023). Here, an experiment known as DAMA/Libra, which started in Italy in 1998, is being replicated. For two decades, what is suspected to be dark matter has been detected at the same time each year in Italy. The Stawell Lab is seeking to verify these results, operating below the equator to determine any potential effect of seasonal interference from the Earth (Darling & Knight, 2022). The research utilises the technology SABRE (Sodium iodide with Active Background REjection), which are sodium iodide crystals that emit flashes of light if a sub-atomic particle hits the nuclei of atoms within the crystals (Darling & Knight, 2022). Hence, if a particle of dark matter hits a nucleus, a tiny flash of light should be created. Simultaneously, researchers at the University of Western Australia have been working on the detection project ORGAN (Oscillating Resonant Group Axion), in order to determine the presence of axions (McAllister, 2022). Despite not having detected any dark matter signals thus far, such experimentation has still offered important insights. Not detecting dark matter within a certain mass range and level of sensitivity allows exclusion limits to be set around the possible characteristics of axions. This tells researchers where to stop looking and, instead, where they should be focusing their resources and efforts. Despite the disarray around “solving” the conundrum of dark matter, alongside its less than reassuring name, it’s not actually something that people should be scared about. The gravity that dark matter is responsible for enables our existence, with dark energy having allowed the expansion of the early universe to become what we see, and don’t see, today (Xenon Dark Matter Project, 2022). Detecting the presence of dark matter is about advancing our understanding of the size, structure, and future of the universe. Current research approaches may seem slightly haphazard, attempting to find something that has never been detected and may not even exist. But when pursuing strange cosmological phenomena beyond our understanding, taking a wild stab in the dark may be exactly what we need to do. References American Museum of Natural History (2000).

Science Ethics Should We Protect Our Genetic Information? By Grace Law What is a top story that has been brewing in our news in recent months? This column provides an introduction to the topic and why we should care about it. For this issue, our focus is on the security of our genetic and biometric data. Edited by Juulke Castelijn & Khoa-Anh Tran Issue 1: September 24, 2021 Illustration by Aisyah Mohammad Sulhanuddin Our genetic and biometric data, like DNA and fingerprints, make each of us unique and identifiable. This information is invaluable in allowing us to verify our identity, predict personal characteristics, identify medical conditions, and trace our ancestry. But there are consequences we should be aware of when we are sharing this data. It is often not known exactly what our information is used for. We must make a more informed decision about the services we obtain in exchange for our biometric and genetic information. The unknown consequences of medical tests Most of us would not hesitate to get a blood or genetic test. These tests have been instrumental in allowing us to identify genetic abnormalities, monitor our health, and provide peace of mind in pregnancies. However, some companies and 3rd parties have exploited the trust patients placed in them to analyse these data beyond the original medical intentions. Reuters reported in July 2021 of a Chinese gene company, BGI, using leftover genetic data from their prenatal test to research population traits (1). The test is sold in at least 52 countries to detect abnormalities like Down’s syndrome in the fetus but it also captures genetic and personal information about the mother. The company confirmed that leftover blood samples are used for population research, and the test’s privacy policy states that data collected can be shared when “directly relevant to national security or national defence security” in China (2). This is not the only instance of genetic data being exploited by a state for mass examination and surveillance purposes. The Australian Strategic Policy Institute (ASPI) published a research paper identifying the Chinese Government Ministry of Public Security’s mass DNA collection campaigns on millions of men and boys (3). It aims to ‘comprehensively improve public security organs’ ability to solve cases, and manage and control society’ (4). Certainly such databases are useful to forensic investigations, but the mass collection of genetic data raises serious human rights concerns regarding ownership, privacy and consent. Furthermore, it opens the possibility of surveillance by the government (5). Everyone should be giving fully informed consent for the usage of their genetic information in accordance with international human rights law (6). ‘At-home’ genetic kits are not guaranteed to be secure Although there is no evidence of such scales of surveillance in Australia, we are not immune to exploitation and questionable practices. Direct-to-consumer (DIC) genetic tests are widely available, often through online purchases. These tests advertise as being able to indicate predisposition to various diseases, including diabetes, breast cancer and heart disease (7). However, as these processes don’t always involve the advice and interpretation of a doctor, there are concerns that data may be analysed beyond current medical understanding. Misinformation, such as misdiagnosis or exaggeration of the certainty of the user’s health conditions, can cause unnecessary anxiety. The discovery of medical predispositions can have ongoing consequences, including refusal of coverage from insurance companies and discrimination by society (8). Under the US Genetic Information Nondiscrimination Act, employees cannot discriminate against employers on the basis of genetic information. Australia currently relies on existing Commonwealth, state and territory anti-discrimination laws to protect against discrimination in public domains (9). Companies are also not regulated by the law in what they do with the information collected. Many have been found to use the information beyond providing results to consumers, such as for internal research and development, or providing it to third parties without additional consent (10). Ancestry tests are another type of DIC test facing similar scrutiny. As we all share genetic information with our relatives, these tests allow us to identify distant relatives, and even help solve mysteries and capture a serial killer (11). Testing companies therefore have portions of genetic information from relatives without needing to obtain their consent, as well as being able to identify familial lineages. These examples highlight the difficulty of protecting consumer privacy and maintaining ownership of our genetic information. The daily convenience of biometric data and its unintended side-effects Most of us do not encounter the aforementioned tests daily, but we often use our biometric data in many aspects of our lives. As technology advances, fingerprint readers, facial scanners, and even retina/iris scanners are available on our phones to replace traditional PINs. These have been widely adopted due to their convenience. However, our security is being compromised in the process. Not only is your device easier to hack compared to passwords, but the collection of biometric data can also be illegally obtained from improper storage (12, 13). We cannot change our biometric data like a password. Once it is compromised, it is beyond our control. Meanwhile, technology is advancing to include new types of biometric data like voice recognition, hand geometry and behaviour characteristics. As our lives become more public through social media, others may be using this opportunity to collect more information. TikTok’s update on its privacy policy recently included permission to gather physical and behavioural characteristics, but it is unclear what it is being used for (14). These examples highlight why we should be aware of the consequences and compromisation we make in using biometric data for daily convenience. Looking to the future There is certainly no shortage of interest in our genetic information and biometric data. Unfortunately, current legislation is fairly general and therefore not equipped to deal with the variety of issues that emerge with specific technologies. Exacerbating this effect are the continual advances made in this technology, with the law simply not keeping up. But that does not mean we are helpless. A landmark case found that an Australian worker being fired for refusing to use a fingerprint scanner at work was unjust (15). This shows our rights over our genetic information are still in our own hands. While we should be vigilant at all times, it should not deter us from accessing the necessary medical tests or saving us a few seconds each time we access our phones. It is more important to protect ourselves: be aware of our rights, the policies we are consenting to, and the possible implications of a service. Whilst appropriate legislation still needs to be developed, we can hold companies accountable for their policies. We should also be critical in whether we publicise all of our information, and be cognizant of the way our data is stored. This is an instance where we really should read the terms and conditions before accepting. References: 1 .

< Back to Issue 4 From the Editors-in-Chief by Caitlin Kane, Rachel Ko, Patrick Grave, Yvette Marris 1 July 2023 Edited by the Committee Illustrated by Gemma van der Hurk Scirocco, summer sun, shimmering on the horizon. Salt-caked channels spiderweb your lips, scored by rivulets of sweat. Shifting, hissing sands sting your legs. You are the explorer, the adventurer, the scientist. A rusted spring, you heave forward, straining for each step, hauling empty waterskins. ----- The lonely deserts of science provide fertile ground for mirages. An optical phenomenon that appears to show lakes in the distance, the mirage has long been a metaphor for foolhardy hopes and desperate quests. The allure of a sparkling oasis just over the horizon, however, is undeniable. The practice of science involves both kinds of stories. Some scientists set a distant goal and reach it — perhaps they are lucky, perhaps they have exactly the right skills. Other scientists yearn to crack a certain problem but never quite get there. In this issue of OmniSci Magazine, we chose to explore this quest for the unknown that may be bold, unlucky, or even foolhardy: chasing the ‘Mirage’. Each article was written entirely by a student, edited by students, and is accompanied by an illustration that was created by a student. We, as a magazine, exist to provide university students a place to develop their science communication skills and share their work. If there’s a piece you enjoy, feel free to leave a comment or send us some feedback – we love to know that our work means something to the wider world. We’d like to thank all our contributors — our writers, designers, editors, and committee — who have each invested countless hours into crafting an issue that we are all incredibly proud of. We’d also like to thank you, our readers; we are incredibly grateful that people want to read student pieces and learn little bits from the work. That’s enough talking from us until next issue. Go and read some fantastic student writing! Previous article Next article back to MIRAGE

< Back to Issue 6 Out of our element by Serenie Tsai 28 May 2024 Edited by Luci Ackland Illustrated by Louise Cen A land teeming with lush forestry and fresh air seems like a far reach from the current state of the world. Not too long ago, this was Earth’s reality. However, with the onset of industrialisation, and the subsequent exploitation of our natural resources, our environment rapidly deteriorated. We polluted our atmosphere and contaminated our waterways with oil and debris. Not only did we pose a threat to human health, we also risked the safety of our future. Experimenting with elements Not long after the Industrial Revolution, the use of nuclear energy arose as an alternative to fossil fuel to combat climate change. Society’s view on nuclear energy became contentious when the largest nuclear disaster to date occurred in Chernobyl in 1986. The explosion of the nuclear reaction caused hundreds to be afflicted by Acute radiation syndrome and many died within a few weeks from this disease (World Nuclear Association, 2022). Following the accident, a 30-kilometre exclusion zone around the power plant was enforced to prevent further contamination to humans. Yet unexpectedly, forest coverage has since increased 1.5 times over (Matsala et al., 2021). In the absence of humans, wildlife appears to be flourishing—in particular, grey wolves are thriving and have become the top predator in the exclusion zone (Itoh, 2018). There remains a lack of research surrounding the long-term implications of radiation on the health of wildlife (Itoh, 2018), good and bad. The negative effects of radiation are evident in the increase of cases of tumour growth and deformed beaks and claws in local birds (Itoh, 2018). The local flora were also negatively impacted with tree rings during the period of the incident indicating that radiation caused a reduction in tree growth (Mousseau et al., 2013). Natural disasters becoming more disastrous Similarly, the impacts of industrialisation have become especially discernible with the increasing severity of natural disasters; effects of which have been further compounded by climate change. Human activities such as the consumption of fossil fuels has played an overwhelming role in the increase of global temperatures, leading to more extreme weather conditions (Wuebbles & Jain, 2001, Nema et al., 2012). These higher temperatures have consequently amplified the intensity of droughts and fire seasons (Liu et al., 2010). Air pollution levels into some areas cause citizens to be perpetually smothered by smoke. Nature’s takeover As the foundation of Earth, nature has the capacity to reclaim areas that humans once inhabited. In Houtouwan, China, a once-thriving fishing village has now been overrun by vegetation. Almost every inch of the village has been camouflaged by vegetation—only mere silhouettes of the buildings remain amongst the greenery. It makes sense that an open area combined with abundant rain and shine would give way to overgrown vegetation; yet a Banyan tree elsewhere in China managed to slowly take root through even just the cracks of a brick floor. In Bangkok, a half-demolished shopping mall is now an oasis for aquatic life. This did not happen of its own accord; the mall was abandoned when it failed local regulations and was then flooded during monsoon season. Locals then introduced fish to prevent insects from breeding in stagnant waters and it has been flourishing ever since. Life is nothing without nature, yet there is a fine line between using nature’s resources for greater good or using it to our demise. There is a dire need to regulate the use of our finite resources. Nature thrives in abandoned places and has the potential to overcome human-inflicted disasters and outlive humanity. References Itoh, M. (2018).

Meet OmniSci Writer and Committee Member Rachel Ko Rachel is a writer and Editor-in-Chief at OmniSci, now in her first year of the Doctor of Medicine. For Issue 4: Mirage, she is writing an interview with science communicator, Dr Karen Freilich. interviewed by Caitlin Kane What are you studying? I am currently studying a Doctor of Medicine and I’m in my first year. Before that, I was studying a Bachelor of Biomed. What first got you interested in science? Exposure through education, stuff I’d studied in school. It sparked interests outside of school and I realised it was something that I wanted to pursue as a career. Something that really reinforced my love for science was doing a major in human structure and function, so anatomy. I really enjoyed that I could weave it in with my other passions in things like art and drawing and painting. I was able to look at science in a way that was really the artsy side of science. It's something I’ve tried to pursue with OmniSci as well. Do you have any advice for younger students? Don’t be afraid of trying all areas of science. Because I loved a specific area of science so much, I wanted to make sure that was what reeled me in as compared to other things. I tried a bunch of research projects, some of them I didn’t really love and I had to stick it out to the end, but then I could tick that off my list as having done that, and never have to do it again. But then I did another project which was 3D modelling a bone. It was just me sitting there for hours with a pen, drawing the bone in 3D space, which was very much up my alley. Don’t be afraid of trying everything, even if it feels like a waste of time in the moment. It isn't, it’s the process of filtering out and finding out what you love. And I’m still in that process. I have no idea what kind of medicine I want to go into, but I’m going by process of elimination and finding where I fit in the realm of science in that way. How did you get involved with OmniSci? Like I said, I like the artsy side of science. I actually sought out a few non-science related magazines at uni. I’ve always been into journalism and I love writing as well, so it made sense for me to look into that in my undergrad years. OmniSci emerged during those undergrad years and I thought, “Perfect!” I was a columnist first and I started doing some illustrations as well. Then I dropped my role at Farrago completely just to concentrate on this because I found it was a really nice intersection of what I love to do. My column was about vestigial features, like useless body parts, which I thought would be a fun, light column–I just wanted something cute and fun. So I started that, and now… I’m in the committee. What is your role at OmniSci? I am an Editor-in-Chief at the moment, and I have also written one of the pieces for Issue 4, purely because of my love for writing and contributing. I might step in as an illustrator at some point… I’m hoping in this break I can sit down and draw a little more than I used to. As Editors-in-Chief, we work with the committee to coordinate the things being published and try to envision what role OmniSci plays within the science communication universe. And whilst figuring out what we’re publishing and putting out to the world, we’re also trying to include the rest of the student community. We also have social events so that we can share our love for…whether it’s science or art or writing… any of the parts that OmniSci encompasses. We're there to keep everything chugging along!. What is your favourite thing about contributing at OmniSci so far? The people that you meet along the way. I do eventually want to pursue science communication myself, alongside medicine. I don’t know what that will look like, but I know that the people who will be involved in that space are the people you meet at the moment. Even with the committee, chatting about things and discussing interests has been super enlightening. When you expand that to the rest of the OmniSci community, I think it’s super super rewarding. Also seeing something tangible come out of it all… I just love seeing the magazine come together. When we printed it—though not ideal for the environment for every issue—to have the paper magazine in our hands from last year was super rewarding to see. Can you give us a sneak peak of what you're working on this issue? Well as Editor-in-Chief, the whole issue is kind of our collective baby! Personally I interviewed Dr Karen Freilich, a GP specialising in sexual health and working in education as well. I was lucky enough to have her as one of my sexual health elective tutors. She also started a podcast when she was in medical school called Humerus Hacks. It is basically super famous within the med student community. It sounds like such a simple thing, but just to hear her and the friend she started the podcast with talk things through and make things entertaining… it was such a fresh way of getting the information out. It’s kind of what we do at OmniSci: make science more accessible to people who might feel intimidated by those bigger, wider topics that they might never have ventured into. And the whole point of a magazine is to get information out to more people, and to spark interest, and show people that these things exist. As a med student, I kind of came across it as naturally as you could have. And as she was my tutor, I thought it was such an important opportunity to talk to her about why she did it and where she sees science communication going. What do you like doing in your spare time (when you're not contributing at OmniSci)? Well, there’s the anatomical art. I haven’t had a lot of time to do that… and I’ve been really wanting to try and incorporate it into my study but I spend a lot of time on one painting so it wouldn’t have been time efficient. But my plan for this break is to go to a bar, get myself a drink and just paint on my own… relax in that way. Otherwise, I play the violin, something I like to destress. It’s actually been a surprisingly big part of my life in med because there's a medical student orchestra. The rehearsals are quite long but it’s actually quite worth it to be sitting there not thinking about medicine. And yeah, just catching up with friends, going cafe hopping, bar hopping, that’s what I like to spend time doing. Which chemical element would you name your firstborn child (or pet) after? Let me pull up a visual aid. I actually don’t mind chemistry, but after year twelve I’ve kind of put a line between myself and it. Have you seen that trend online where people are pulling up words that would be really pretty baby names if they didn’t mean what they meant? Ooh, I’m going to go with Livermorium, Liv for short. Element 160. There’s some good ones—you could go Rutherfordium, Ruth for short.

< 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

The Greenhouse Unpacking the Latest IPCC Report - What Climate Science is Telling Us By Sonia Truong The most comprehensive climate science report to date, this sixth assessment report reveals the reality of climate change and stresses that we need to take action urgently. Edited by Jessica Nguy & Yen Sim Issue 1: September 24, 2021 Illustration by Jess Nguyen On the 9th of August 2021, the United Nations Intergovernmental Panel on Climate Change (IPCC) released its first instalment of the IPCC Sixth Assessment Report from Working Group I, Climate Change 2021 — The Physical Science Basis of Climate Change. The IPCC is one of the world’s leading authorities on climate change and its reports provide an important scientific framework for governments to develop climate policies. With the collaborative effort of 234 leading climate scientists and more than 1,000 contributors, the latest IPCC report provides the most up-to-date information about the scientific basis of climate change and the effects of human activity on Earth’s systems. The report can be found online — it features a ‘Summary for Policymakers’ document exploring key findings across four topic areas as well as a comprehensive ‘Full Report’ which assesses and compiles peer-reviewed literature on climate science from across the globe. The report also features the IPCC WGI Interactive Atlas which explores observed and projected regional climate changes across different emissions and warming scenarios. Three key takeaways from the IPCC report are described below. #1: Human activity has contributed to climate change It in unequivocal that human influence has warmed the atmosphere, ocean and land. Headline statement from the IPCC’s ‘Summary for Policymakers’, AR6 2021 Advancements in attribution studies have allowed scientists to better simulate Earth’s responses to natural and anthropogenic factors and estimate the extent of human influence on observed climate trends. For the first time, the IPCC report has been able to state with a very high level of certainty that anthropogenic factors have been the main driver of increasing temperature extremes since the mid-19th century. Figure SPM.1 shows that simulated natural factors do not come close to explaining the observed increase in global surface temperature since the mid-19th century. Figure SPM.1: A powerful comparison of changes in global surface temperature since 1850 with and without human factors. This figure shows that the effects of natural climate drivers on global warming have been negligible compared to human influence on the climate. IPCC AR6, ‘Summary for Policymakers’ Atmospheric greenhouse gas concentrations are higher than what they have been in the last two millennia and have been increasing at an unprecedented rate, mainly due to human activities in greenhouse gas combustion and deforestation. According to the report, greenhouse gas emissions from human activities have caused warming of approximately 1.1°C above pre-industrial average. In fact, human activities have caused enough emissions for even greater warming, but this has been partially counteracted by the cooling effect of aerosols in the atmosphere. Some recent heat extremes would have been virtually impossible without the influence of human forcing factors. Siberia’s prolonged heatwaves of 2020, for example, would have occurred less than once every 80,000 years without human-induced climate change. Moreover, the onset of Siberia’s wildfire season saw record-high temperatures throughout 2020 and 2021 as well as the burning of over 16 million hectares of land. Even in today’s climate, such extreme weather events are unlikely, but have been predicted to become more frequent by the end of this century. #2: Every region will experience environmental changes due to climate change The IPCC report states that the “widespread, rapid and intensifying” effects of climate change will be experienced by every region in a multitude of ways. Since the release of the last IPCC report in 2018, the world has observed an increase in acute weather events such as widespread flooding, storms, drought, fire weather and heatwaves. These are predicted to increase in frequency and severity as a result of human-induced climate change. Many changes in the climate system become larger in direct relation to increasing global warming. They include increases in the frequency and intensity of hot extremes, marine heatwaves, and heavy precipitation, agricultural and ecological droughts in some regions, and proportion of intense tropical cyclones, as well as reductions in Arctic sea ice, snow cover and permafrost. B.2 from the IPCC’s ‘Summary for Policymakers’, AR6 2021 Several environmental changes due to climate change are already irreversible. Notably, global sea level rise and ocean acidification are set in long-term motion and will proceed at rates which will depend on future emissions. Glacial retreat is occurring synchronously across the world and glaciers will continue to melt for decades or centuries. All emission scenarios within the 21st century described in the report have revealed that global temperature changes will exceed a 1.5ºC increase, even in the lowest emissions scenario (SSP1-1.9). Thus, warming will reach a critical level regardless of actions that the world takes now. We can, however, prevent further temperature increases with deep reductions in global greenhouse gas emissions (especially carbon dioxide and methane). Figure SPM.5: All regions of the world (with one exception) will experience warming as a result of climate change, although not at an equal level. IPCC AR6, ‘Summary for policymakers’ Environmental changes at a 2ºC warming will be more pronounced and widespread, and extremes are likely to exceed critical tolerance thresholds in human health, ecological systems and agriculture. Australia, in particular, is vulnerable to experiencing scarce water resources in drought-prone areas and flooding and landslide events due to heavy rainfall events. Australia’s coastlines are also prone to erosion and flooding from rising sea levels and extreme meteorological events. The IPCC report examines evidence for climate ‘tipping points’ which, due to uncertainty about the Earth’s feedback systems, “cannot be ruled out” in climate projections. These tipping points are key thresholds that will lead to large-scale and irreversible damages to the Earth’s systems if breached. One of these tipping points is the loss of the Greenland ice sheet which is melting at an unprecedented rate. Surface melt of this major ice sheet involves a number of positive feedback loops which exacerbate the melting as the ice surface gets darker and less reflective of solar radiation. Scientists warn that, while highly unlikely, there is a possibility that we will reach a tipping point with current warming trends. #3: We need to make drastic reductions in greenhouse gas emissions immediately The Sixth Assessment Report tells us, with greater certainty than ever before, that human activities over the past six decades have caused global warming trends and affected climate extremes globally. These trends are likely to continue on a long-term scale. Most importantly, the report stresses that if we want any chance of limiting global temperature rise to 1.5ºC above pre-industrial levels, we must urgently make strong, sustained reductions in global greenhouse gas emissions. The current global carbon budget to remain below 1.5ºC warming is estimated to be at an additional 500 billion tonnes of greenhouse gas. To remain within this budget, we need to achieve net zero carbon dioxide emissions by 2050. Reductions in greenhouse gas emissions will only be achieved with meaningful climate action. If we can drastically reduce emissions now, we will still have a chance of averting the climate crisis. The two succeeding instalments of the IPCC Sixth Assessment Report will cover the impacts of climate change and mitigation of climate change and are planned to be released in 2022.

< Back to Issue 5 Wicked Invaders of the Wild Serenie Tsai 24 October 2023 Edited by Krisha Darji Illustrated by Jennifer Nguyen Since the beginning of time, there has been a continuous flow of species in and out of regions that establishes a foundation for ecosystems. When species are introduced into new environments and replicate excessively to interfere with native species, they become invasive. Invasive species refer to those that spread into new areas and pose a threat to other species. Factors contributing to their menacing status include overfeeding native species, lack of predators, and outcompeting native species (Sakai et al., 2001). Invasive species shouldn’t be confused with feral species which are domestic animals that have reverted to their wild state, or pests which are organisms harmful to human activity (Contrera-Abarca et al., 2022; Hill, 1987). Furthermore, not all introduced species are invasive; crops such as wheat, tomato and rice have been integrated with native agriculture successfully. Many species were introduced accidentally and turned invasive; however, some were intentionally introduced to manage other species, and a lack of foresight resulted in detrimental ecological impacts. Each year, invasive species cost the global economy over a trillion dollars in damages (Roth, 2019). Claimed ecological benefits of invasive species Contrary to the name, invasive species could potentially benefit the invaded ecosystem. Herbivores can reap the benefits of the introduced biodiversity, and native plants can increase their tolerance (Brändle et al., 2008; Mullerscharer, 2004). Deer and goats aid in suppressing introduced grasses and inhibit wildfires (Fornoni, 2010). Likewise, species such as foxes and cats have the capacity to regulate the number of rats and rabbits. Furthermore, megafaunal extinction has opened opportunities to fill empty niches, for example, camels could fill the ecological niche of a now-extinct giant marsupial (Chew et al., 1965; Weber, 2017). Thus, studies indicate the possibility of species evolving to fill vacant niches (Meachen et al., 2014). Below, I’ll explore the rise and downfall of invasive species in Australia. Cane toad Cane toads are notorious for their unforeseen invasion. Originally introduced as a biological control for cane beetles in 1935, their rookie status was advantageous to their proliferation and dominance over native species (Freeland & Martin, 1985). Several native predators were overthrown and native fauna in Australia lacked resistance to the cane toad’s poison used as a defence mechanism (Smith & Philips, 2006). However, research suggests an evolutionary adaptation to such poison (Philips &Shine, 2006). There isn't a universal method to regulate cane toads, so efforts to completely eradicate cane toads are futile. However, populations are kept low by continuously monitoring areas and targeting cane toad eggs or their adult form. Common Myna The origins of Common Myna introduced into New South Wales and Victoria are uncertain; however, it was introduced into Northern Queensland as a mechanism to predate on grasshoppers and cane beetles(Neville & Liindsay, 2011) and introduced into Mauritius to control locust plagues (Bauer, 2023). The Common Myna poses an alarming threat to ecosystems and mankind, its severity is elucidated by its position in the world’s top 100 invasive species list (Lowe et al., 2000). It has spurred human health concerns including the spread of mites and acting as a vector for diseases destructive to human and farm stock (Tidemann, 1998). Myna also has a vicious habit of fostering competition with cavity-nesting native birds, forcing them and their eggs from their nest, however, the extent of this is unclear, and the influence of habitat destruction needs to be considered (Grarock et al., 2013). The impact of this bird lacks empirical evidence, so appropriate management is undecided (Grarock et al., 2012). However, modification of habitats could be advantageous as the Myna impact urban areas more, whereas intervening in their food resources would be rendered useless with their highly variable diet (Brochier et al., 2012). Zebra mussels Zebra mussels accidentally invaded Australia's aquatic locality when introduced by the ballast water of cargo ships. From an ecological perspective, Zebra Mussels overgrow the shells of native molluscs and create an imbalance within the ecosystem (Dzierżyńska-Białończyk et al., 2018). From a societal perspective, it colonizes docks, ship hulls, and water pipes and damages power plants (Lovell et al., 2006) Controlling the spread of Zebra Mussels includes manual removal, chlorine, thermal treatment and more. Control methods It is crucial to deploy preventative methods to mitigate the spread of invasive species before it becomes irreversible. Few known control methods are employed for certain types of animals but with no guarantee of success. Some places place bounties on catching the animals, however, the results of this technique are conflicting. In 1893, foxes were the target of financial incentives, but the scheme was deemed ineffective (Saunders et al., 2010). However, government bounties were introduced for Tasmanian tigers in 1888, which drastically caused a population decline and their eventual extinction (National Museum of Australia, 2019). Similarly, the prevalence of Cane Toads became unbearable, and in response, armies were deployed, and fences in rural communities were funded. Moreover, in 2007, inspired by a local pub’s scheme to hand out beers in exchange for cane toads, the government staged a “Toad Day Out” to establish a bounty for cane toads (Williams, 2011). Invasive species are detrimental to ecosystems, whether introduced intentionally or by accident, management of species is still a work in progress.

< Back to Issue 4 Real Life Replicants by Elijah McEvoy 1 July 2023 Edited by Yasmin Potts and Megane Boucherat Illustrated by Jolin See Hal, Ultron and (of course) the Terminator. Comparisons between these fictional, world-destroying, artificial intelligence systems and those in our current age of AI are seemingly never-ending. As a child born with a lightsaber in hand, I find these sensationalist remarks endlessly entertaining. Not only because it baffles me to see concepts once relegated to the realm of science fiction be discussed as serious news topics, but also because they’ve got their references all mixed up. The current challenge posed by the new wave of generative artificial intelligence doesn’t come in the form of a ruthless, gun-toting Arnie. It comes in the form of replicants. Just like these uncannily human androids from Ridley Scott’s cult classic Blade Runner, the rapidly increasing capacity of AI to talk, look and create like humans is beginning to blur the line between what is authentically human and what is the product of an algorithm. From the posh C3P0 to the snarky Cortana, having a friendly AI sidekick has always been a childhood dream of mine. This dream has now become a reality with the rise in AI chat-bots. At the forefront of these is Replika, an app that enables users to talk to their own personalized AI via the use of text-like messages. For its two million users (1), Replika provides a variety of functions. For some, Replika acts as a friend in times of loneliness; a feature that contributed to its spike in users during the height of the COVID-19 pandemic (2). For others, as founder Eugenia Kuyda suggests, it provides a space for users to “open up” about personal or mental health issues and “feel accepted” by a human-like figure (1). For many though, Replika is a digital romantic partner. While it is easy to snicker at the concept of an AI girlfriend, those with past relationship trauma or those living in environments that may be hostile towards their sexuality have used Replika as an outlet to explore genuine feelings of love in a safe setting (3). However, with such attachment comes the chance for exploitation. As stated by Nir Eisikovits, Director of the Applied Ethics Centre at the University of Massachusetts, his concern is “not whether machines are sentient” but rather our own tendency “to imagine that they are” (4). Like the holographic billboards for the AI “JOI” in Blade Runner 2049, suggestive advertisements and aggressive flirting by the AI itself have all been employed by Replika to encourage users to stay on the app and pay a premium subscription for explicit content (5). While Replika has since removed sexual material, the large backlash from users at this decision (6) highlights the unethically coercive power such mimicry of human personality could have on consumers. For years, we’ve been warned of the danger of manipulative TV advertisements encouraging excessive junk food consumption and gambling. Imagine what could be done when that ad is no longer a 30 second video but instead an anthropomorphized AI tailored exactly to you, your interests and your vulnerabilities. Not only is AI replicating the way we talk, but also how we look. From videos of an animated Tom Cruise to convincing photos of a Balenciaga-wearing Pope (7), advanced deepfake videos and prompt-generated images from AI systems like DALL-E are becoming easier to create by the day (8). While the most prominent use of this technology is currently in the form of harmless memes, it can and has been used for more sinister means. Women across the world have had their faces used in non-consensual deepfake pornography, often as a form of revenge or blackmail (9). Furthermore, a fabricated video of Volodymyr Zelensky surrendering to Vladimir Putin that spread on social media last year proves AI’s unsettling potential in political disinformation (8). While fakes like that of Zelensky may have been taken down quickly due to easily identifiable tells, in many cases the damage has already been done the moment people see these videos or images. Mistrust in the news is heightened and real evidence can be accused of being AI generated, a strategy already implemented by Donald Trump to dismiss evidence of his misogyny (8). Although the current usage of this technology is concerning enough, the degradation of truth within society will only worsen as these replicants become increasingly accurate and faster to produce (8). Still, it is the ability for AI to complete jobs once thought to be uniquely human that will result in the largest change to the current status quo. Latest estimates from Goldman Sachs state that close to 300 million jobs globally could be automated by the current AI wave (10). The threat of job losses due to automation is far from new, stretching all the way back to 1811 with the infamous Luddites protesting factory machines (11). However, generative AI is placing a greater variety of jobs in jeopardy due to its ability to exude human creativity, giving rise to what Stanford Professor Victor R. Lee entitles an “authenticity crisis” (12). One of those jobs is that of writers. A common phrase amongst movie reviewers today is “this could have been written by an AI”. While usually used as a jab against the latest Marvel movie, large language models like Chat GPT that are capable of identifying and mimicking patterns in writing make it more than just a joke. Amongst calls for better conditions for screenwriters, a key demand from the Writers Guild of America in this year's Los Angeles writers’ strike was that AI will not be used to write or rewrite scripts (13). When you combine the growing authenticity of these AI with the greedy desires of major studios, it is not a far cry to suggest that producers may use AI to quickly generate scripts for generic soap operas and cash grab Netflix movies, leaving the human creatives to simply ‘clean-up’ these stories at a cut pay rate. Despite all these concerns, generative AI does have the ability to immeasurably improve society. The capacity of this technology to increase workplace efficiency (10), accelerate scientific progress (14) and constantly amuse us with clips of a rapping Joe Biden is undeniable. With the cat out of the bag, innovation in these areas cannot nor should not be halted completely. However, if sci-fi movies have taught me anything useful, it’s that we should not be blinded by the potential of scientific progress. Whether it be through governmental action to regulate the use of AI in industry or the scientific development of better deepfake-spotting technology to help stifle disinformation, implementing safeguards around AI is crucial in avoiding its “ethical debt” (15). Whilst looking to the world of science fiction as an indication of our future may be a bit far-fetched, it may also be a needed reminder of the world scientists should try not to replicate.

'Science is everywhere' Competition Submissions Scroll to view the submissions we received for National Science Week 2021! Lily Robinson, 20 Science is everywhere in our lives. As soon as you take a walk outside, you are immersed in it. This picture is of a dam at my family home at the end of a drought. The water was crystal clear and there were these amazing deep cracks in the mud. I decided to rotate the image upside down to symbolise the impact of the drought upending our lives and the bush around us. Rebecca André, 23 I captured this photograph on my Olympus OM-2 film camera while out on a lunchtime walk. At first I took no notice of this indistinct bunch of leaves but as I moved around them the sun caught my attention and I noticed the illuminated veins. This photgraph reminds me that the beauty of the natural world is all around us all the time, if only we are mindful to observe it. Through science and observation, the beauty of unseen worlds and intricate truths are revealed to us. Sajitha Biju, 36 Vivipary in papaya fruit: Viviparous germination is a type of seed germination seen in plants, where the seeds/embryo begin to develop before they detach from the parent plant. Viviparous germination is also seen in the mangrove Avicennia. Stephanie Tsang, 25 A photograph of a jellyfish pulsing through the cold waters of Port Philip Bay, Victoria. It has no brain nor heart. Science is spectacular and can be found submersed underwater. Cnidarians have been around for millions of years and later and are the common ancestors of many other creatures. The oldest fossils found date back to around 500 million years old. They are found all over the world following the ocean currents.

They are found all over the world following the ocean currents. Betty La, 24 I like to practise on this contraption of wood, metal and vibrating air almost every morning. My motor pattern for the music is set into motion, followed by eighty-eight felt-covered hammers acting as oddly-shaped springs, dancing along steel strings wound with copper. They are spurred on by levers of black and white. The sound is amplified from a wooden soundboard, which expands and contracts imperceptibly with the temperature of the room. Ella Banic, 19 I wish I could explain why I think science is everywhere, but it is too ubiquitous for me to comprehend. In my artwork I have been interested in the relationship between humans and nature, particularly in the liminality of experience. While I can’t really describe what science is or where to find it, in this piece I see science as a life force; which gives us direction and allows us to see above the surface. Sarah Wehbe, 18 This photo of a strawberry was taken with a magnifying glass to show the individual hairs and textured skin of the strawberry that you wouldn't normally notice. These fibrous hairs protect the fruit from insect damage and each of these yellow seeds contain the DNA to produce a whole new strawberry plant. Biological sciences are all around us in the foods that we eat. Junsheng He, 18 This photo of the Moon was taken on the 26th of May this year, the day when the total lunar eclipse took place. When we think of the Moon, it is always an image of a shining silverish sphere. Nevertheless, in this particular night, red light shines to the Moon when it is passing through the shadow of the Earth, turning it to the "Blood" Moon. It insinuates that even the seemingly ordered patterns, the forever rotating heavenly bodies, can change their property driven by the power of science. Minchi Gong, 20 Furry Buddy and Pumpkin: I’ve got a pumpkin from the market, and left it on my desk for a couple of weeks because I was too busy to cook it. One day I surprisingly found that there’re a bunch of furry moulds growing on its body, which successfully caught my eyes. Wow I never thought the mould can be so AESTHETIC! Seems like these little furry microorganisms are so keen to show their sense of presence and to express their interpretation of arts. Louie Minoza, 30 Here we witness the first moments of a new born calf. As it witnesses the warm glow of the setting sun for the first time, unconcerned on where the bright light is going. Taking in the textures and scents of the grass under its body. The feeling of fullness as it suckles on it’s mothers teat after instincts urges it to go against gravity. This new found freedom shall be utilized to embark and explore this world it was born in. Caitlin Kane, 20 Have you ever wondered how a clear sky becomes an electrically charged thunderstorm? Electric currents, like those that flow in our powerlines, are made by the movement of tiny charged particles called electrons. When operating safely within a house, electricity can light a bulb, keep a fridge chilly or charge a car. In the big woolly clouds above our heads, the movement of dust, ice and water can create a static electric charge, like when hair is rubbed with a balloon. Sachinthani Karunarathne, 28 years In the fall, you see trees having photogenic colours. Trees do this not for the beauty what we see but to conserve energy during winter. Because due to changes in the length of daylight and temperature, the leaves stop their food-making process (photosynthesis). So, chlorophyll pigment breaks down, the green colour disappears, and the yellow to orange colours become visible and give the leaves part of their fall splendour. Caelan Mitchell, 23 Copper is one of my favourite metals. It has a significant history, and it looks stunning. It looks even more stunning when you catch an everyday object stained by a rich patina — a complex of copper oxides formed by heat and air. I've never seen anything like this. Joanna Stubbs An Australian native Eucalypt growing for years next to an urban creek and bike path in inner city Melbourne. Scientific research is required in how anthropogenic climate change will affect specific tree species, and inform measures on how best to ensure their survival in a warming climate. Sachinthani Karunarathne, 28 Blood oranges may have a sinister-sounding name, but they’re just a natural mutation of standard oranges. This mutation led to the production of anthocyanins, which make not just blood oranges bright red but also blueberries blue. The flesh develops its characteristic maroon colour when the fruit develops with low temperatures during the night. The anthocyanin pigments continue accumulating in cold storage after harvest. Longer the fridge time redder they become! Sachini Pathirana, 28 A microscopic image of a cell? Nah it’s simple kitchen science. When you wash oily dishes, you will see oil droplets forming thin layers like this on water. This is because adhesive force between oil and water molecules is greater than cohesive force between oil molecules. So, the oil molecules do not mix with water molecules. As a result, oil spreads on the water surface forming a thin layer. Sachini Pathirana, 28 Kernel colour was used to unravel an odd phenomenon in non-Mendelian inheritance: transposons. Transposons are stretches of DNA that jump from place to place in the genome, and landing in the middle of a pigment gene would alter the colour of that cell. Barbara McClintock won a Nobel Prize for her discovery of these transposons. Even the regular white/yellow corn you find in supermarkets has made big genetic leaps. Yitao Gan, 21 The beauty of nature from the preys, harvesters and predators. Christian Theodosiou, 19 My entry shows a sapling in the foreground and a waterfall in the background, captured at midday in the Springbrook mountains of Queensland this year. I aimed to photograph the scene so that perspective gives the appearance that the young plant is being watered by the waterfall and I think that the forms of the leaf and the white foamy water are quite complementary. Even though this waterfall does not directly feed this plant, the fact of their shared environment draws a life-giving relationship between them anyway. Science is everywhere because we, like all complex or simple organisms, are situated within and sustained by infinite webs of interdependence. Whether biological or more molecular, all science everywhere is defined by both obvious relationships, and those that take more time, devotion and study to identify. Teck-Phui Chua, 22 A sapling is growing where an older tree once grew. However, upon closer inspection, the older tree never fully died; part of it was still alive which has allowed a sapling to sprout from its trunk. In a similar vein, science is everywhere and has always been, but what has changed is how much we understand as one generation passes their knowledge onto the next so new discoveries can be made. Additionally, the tree may have seemed dead, but there was still life in it. Whether we choose to act on strong scientific evidence or ignore it, the science will still be there. Sarah Wehbe, 18 Interactions between living organisms are everywhere and are the essence of life itself. This image illustrates the commensal relationship between algae and turtles. The turtle’s shell provides an ideal surface for the algae’s growth, and the turtle is completely unaffected by its presence. In fact, it may help turtles camouflage and hide from prey. This simple interaction between living organisms highlights the existence of science in every aspect of life. Grace Li, 22 Science is often overlooked as a form of art due to its ubiquity. However, a simple photograph can be the reminder needed that science is not only everywhere, but it is beautiful. For example, a photograph is the result of photons travelling from the sun, bouncing off objects, and landing on a camera's sensor. Similarly, these incredible macro-photographic patterns of a lamp is captured by photons travelling through optic fiber. Christina Evans, 43 The bee retrieves pollen from the prickly thistles & how it's all stored on its hind legs like saddlebags. Xuezhi Yang It is fascinating how science is present everywhere, oftentimes interacting with itself creating intricate and mesmerizing works of art. In my artwork, I attempted to capture the anatomy and essence of the Antelope Jackrabbit's ears as light rays penetrate through them. Without light, the delicate and daedal arteries and veins would have been otherwise invisible, tucked away in fur and cartilage. If we truly pay attention, art is found everywhere in science.

< Back to Issue 4 Interviewing Dr Karen Freilich by Rachel Ko 1 July 2023 Edited by Caitlin Kane Illustrated by Pia Barraza Science in the real world is never straight-forward. The realm of medicine and health is particularly intricate, riddled with myths and marvels. This makes the healthcare journey a difficult one to navigate, both for the patient, and for the provider. It is undeniably a field where an ever-evolving myriad of factors makes the bedside experience vastly different to the textbooks. In my first year studying medicine, I am constantly realising that a strong understanding of the fundamentals is often a saving grace, while learning to dispel the mirage of medicine as a simple science. Enter Humerus Hacks , a podcast recommended to me in the first week of medical school by peers who had walked the treacherous road before. A guiding light in the murky waters of medical education, Karen and Sarah’s playful banter lays out high-yield medical content with catchy mnemonics and gracious advice. In this interview, we had the special opportunity to talk to Dr Karen Freilich, one of the hosts of Humerus Hacks , about her journey in medicine so far as a young GP, and the story of how she created a podcast that masters the art of science communication in a perfect marriage of education and entertainment. Tell us about your journey with science, and your career so far. I’ve just completed my GP Fellowship training after about 12 years of study. It’s a relief to be done —medicine is a long slog! I’ve had a brilliant time and been fortunate to take part in exciting studies. I took some time off clinical medicine to complete a Masters of Reproductive and Sexual Health Research in London (LSHTM) as well as completing a Diploma of Obstetrics (DRANZCOG). I currently teach at the University of Melbourne’s Medical School as a tutor in Sexual Health, and write and train high school sexual health educators through Elephant Ed. I work as a GP most days of the week, in a clinic with a focus on sexual and reproductive health and I’m a proud medical abortion and contraception provider. I’m also fortunate to work at Monash in the Sexual Medicine and Therapy Clinic, and work together with the Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine (ASHM). It’s a tricky balance wearing a number of hats, but I love the diversity. Unsurprisingly everything I do is focused in sexual and reproductive health through clinical work, education, advising and science communication. My career is certainly tailor-made to my interests and passion, and took quite some time to get to this point! I love being able to educate on both a one-on-one and broader level on sexual and reproductive health care, particularly through a reproductive justice lens. What was the inspiration behind Humerus Hacks ? In the early years of medical school, my mate Sarah and I used to spend hours and hours trying to memorise different antibiotics and the differences between them. It felt incomprehensible to have to learn not only a new science, but an entirely new language behind it. It felt like a Duolingo course! So in order to scrape through exams, we made silly little stories to try and remember the differences between gentamicin, amoxicillin etc.. Fast forward a few years and Sarah and I ended up running a weekly study group for the year below us, filled with our mnemonics and silly stories. We developed a bit of a cult following (if I say so myself!). It seemed there was a real appetite for otherwise tedious and dry medical education made fun and entertaining. In final year, we both ended up on placements requiring huge drives. We turned to podcasts for ‘edutainment’ — and found there simply were none. So we did what everyone in 2016 was doing, bought a microphone and recorded our own. We were a bit mortified at the start and convinced we wouldn’t get internships if our future employers heard us swearing and being inappropriate online, so we hid our faces and were anonymous with our names. Fortunately it turned out we had nothing to be nervous about, and Humerus Hacks was a hit. Sarah is a musical genius and recorded the intro song with her band. It’s now been over 50 episodes and over 150,000 downloads. We’re often in the iTunes Medical Podcasts Top 10! The inspiration has and always will be pure study laziness — trying to make studying more interesting, fun and accessible and ultimately, more memorable. What is the process of developing and recording an episode? Me, Sarah, or another co-host or friend (Callum, Bridget, Robbie and Dan to name a few!) sitting on a couch with a microphone and chinwagging about a topic. If we’re lucky, maybe some prep. I’d love to suggest it’s more fancy than that! I have brilliant colleagues who play an integral role. Alex edits our episodes and does a brilliant job. And Bella creates fantastic art for the episodes. Sometimes I play around on Canva too for some social media. Shout out as well to our friends who helped with some graphic design and audio. It’s definitely a team effort, and so many people to thank for their ongoing contributions and support. What is your relationship with your audience like? Our audience sends us messages and emails all the time — even if we haven’t made an episode in months! It’s a joy to receive any messages and warms our hearts every time. We get the most delightful and lovely messages. We also get a lot of requests which I wish we could keep up with more, the irony of doing our own exams over the past few years! We try to respond to all messages and keep up with requests. Knowing that our silly little mnemonics has helped anyone with exams is a huge joy. How has science communication evolved since you began? Mnemonics have been a huge part of medicine for a very long time. In fact, I have my uncle’s Medical Mnemonic book from 1958! Some of them have aged terribly, unsurprisingly, but many we still use to this day. So, we are far from inventing the wheel. In saying that, the boom of social media and podcasts over the past few years has lent itself to subspecialised Instagram pages, YouTube channels and more podcasts than I could have ever imagined. Making medical education (and science communication) fun has become much more mainstream and accepted as a genuine study tool. Who knew, making dry education entertaining actually works…! What has been the biggest challenge in your science communication journey? Hands down, time. I run Humerus Hacks with a group of excellent friends and colleagues, but we all happen to be medical students or doctors. Unsurprisingly, it means we are all always bogged down with shift work, exams, and burn out. Humerus Hacks is a labour of love. So we make an effort if and when we can, without any time pressure. I wish we had more time! What role would you say science communication plays in your daily practice? I’m a GP with a special interest in sexual medicine as well as a sexual health tutor for medical students. I also write and train individuals to run high school sexual health education. I’ve also been fortunate to be a guest host on ABC Breakfast Radio under ‘Doctor Breakfast’ providing science communication for a number of medical topics. So, it plays a huge role in my daily practice! I particularly enjoy the interplay of small scale science communication through one-on-one patient interactions compared with larger scale communication through radio, teaching and podcasts. They balance each other really well, and I enjoy the individualised, tailored approach whilst simultaneously thinking of the broader public health messaging. What role would you say science communication plays in society generally? There is so much misinformation floating around. As a huge fan of social media and TikTok myself, I can see how these avenues can be both a wonderful source of information but simultaneously promote unnuanced, oversimplified and often blatantly incorrect health messaging. Social media (including podcasts) provides a really accessible, often free avenue for science information that is otherwise inaccessible. However, we have a responsibility to ensure the information is correct, up to date, and safe. Social media loves a quick snap messaging, but science is almost always more nuanced and complex. A 30 second TikTok often unsurprisingly misses the mark! So, accurate and accessible science communication is the key — the hard thing is making it fun and interesting. What are your immediate goals in science communication this year, and what do you hope to achieve in science communication in the long-term? Great question! I am thoroughly enjoying my career balance at the moment. It’s a great mix of GP clinic, sexual medicine and therapy clinical work, sexual health teaching, and radio/podcasting. I’d love to make more Humerus Hacks episodes now that I’ve finished my own training and have (hopefully) both more knowledge and time! I’ve put together a SPHERE Sexual and Reproductive Health podcast focusing on upskilling clinicians to provide medical abortion and contraception in primary care. I am also loving radio work and would love to keep going with this. I may or may not delve into the TikTok world… watch this space! Long term, hopefully ongoing science communication in the field of sexual and reproductive healthcare. What advice would you give to students exploring the world of science communication? Social media is a game changer that had only just begun when I was a student. TikTok, Instagram etc all provide a free and accessibly way to both gain knowledge and skills, and to educate others. Science students in all disciplines have such incredibly knowledge and insight, and if you’re interested, there’s a willing and enthusiastic audience out there. The phrase ‘see one, do one, teach one’ forever rings true. Teaching and providing science communication helps your own education, and has always been my favourite learning tool. Finally, and I cannot emphasise this enough, being a student is long, tedious, and exhausting. Enjoy the process and look after yourself and your colleagues as a priority! ------------------- It is undeniable that Humerus Hacks is a project succeeding on its steadfast mission to uncover the mirage of medicine. Through a blend of education and entertainment, it reveals the intricate realities of science in health, as a complex and ever-changing landscape that demands a strong foundation of knowledge and willingness to adapt. We extend our heartfelt gratitude to Dr Karen Frielich, for not only agreeing to talk to us, but also for all of her work to demystify the healthcare journey, both for the professional, and for the patient. You can check out 'Humerus Hacks' on Spotify , on Apple Music , or online! Previous article Next article back to MIRAGE
