  • Is there a scientific case for aliens?

    When I was little, my family used to go to a restaurant called Space Aliens. It was a bit like Chuck E. Cheese but instead of a mouse, it was alien themed — the little green kind. The dining area was decked out with all the typical sci-fi space gadgets (UFOs, spaceship control panels, galaxy murals, etc.), the play area had space-themed games, and the prizes were gizmos of the alien variety — stickers, statues, and other miscellaneous trinkets. As a young kid, it was fun to see what size alien statue I could win by playing the arcade games, but as I got older, I started to ponder whether aliens were actually real or not.

    In 2020, right before the world shut down, my friends and I took a spring break trip to New Mexico, USA — the destination of note: Area 51. Turns out tourists can’t actually access Area 51, but we did enjoy the town closest to it, particularly the small business offering sets of alien statues to take pictures with. Again, those alien statues were the stereotypical alien depictions that I’m sure comes to mind for most people.

    Modern movies have branched out at least. Star Wars, Star Trek, and Guardians of the Galaxy are a few of the relatively recent movies that come to mind. Most of the aliens in these movies look nothing alike; in fact, they look different depending on which planet they originate from. This concept of different planets hosting different types of life forms could actually be the more realistic scenario.

    Exobiologists, or astrobiologists as they are more commonly referred to now, are scientists who use modern science to search for life elsewhere in the universe. The problem they run into, though, is that nobody really understands what life is yet. Sure, we know life exists on Earth. To us, living systems are the plants, animals, bacteria, and people we encounter on a daily basis. Biological organisms are life, but why? We see the macro version of life. Take humans, for example. We eat, we breathe, we sleep, blood pumps through our veins, we grow, we die. We are alive. Now think about grass. Grass grows, it takes in nutrients, it participates in photosynthesis (analogous to respiration in animals), and it dies. Neither example looks like the other, yet we know that both are alive. How then, can we determine what life is, if all examples look different?

    One option is to zoom in to look at the processes happening inside the organisms. At the micro-scale (10-6), we start to see cells which have also been deemed to be alive. These cells take in nutrients, participate in (cellular) respiration, carry out functions, then die. Zoom in even further and we find information about the organism encoded in DNA that is constantly being replicated, transcribed, and edited. That DNA is made up of amino acids which are structures made up of many atoms chemically bound together. At what point do we stop saying something is alive? Then, even if we can determine what life is, how can we find it on other planets?

    Stay tuned for next week’s article where we will explore the question “what is life?” through recent publications in peer-reviewed journals.

  • Graduate School: A Cautionary Tale from a Two-Time Dropout

    I tried graduate school twice but dropped out after one year both times. It wasn’t that I couldn’t handle the academics (I had completed all the required coursework in my first degree and was halfway through the requirements of the second), I couldn’t handle the competitiveness of academia.

    For years, I had tied my self-worth to my academic success. I studied hard, got good grades, skipped a grade, made dean’s lists and honor rolls, and graduated early. By all accounts, I was successful. Except, graduate school is not about coursework or grades, it’s about research.

    I was always so eager to learn that I soaked up any information I was given or could find for nearly all the topics covered in high school and during my bachelor’s. I thought graduate school would be more of the same. What I didn’t realize was that graduate school prepares you to be an expert on one topic: the topic you research. In graduate school, you spend years planning experiments, writing procedures, testing hypotheses, reviewing literature, and presenting your findings for the niche topic you chose when you started. That works for a lot of people, but it does not work for me.

    I am a very self-motivated person. I work well independently and can focus on tasks for significant periods of time. I put my all into every project I do. This seems like it would be the perfect profile for a graduate school candidate, but actually, it is the perfect recipe for burnout.

    In graduate school, there are no set working hours. You decide your schedule. You still answer to your supervisor and have deadlines to meet, except those deadlines are often months to years in the future. You have to budget your time well enough to meet those deadlines. Simple in theory, difficult in practice.

    When you are in graduate school, there is a shiny star called “the future” to guide you through the massive amount of work you must complete. You are enticed by the promise of a high paycheck and notoriety if you make a significant contribution to your field. You work diligently, day and night, to perform the necessary experiments, gain credible data, and write informative prose, only to find out that a mere five people will ever read your dissertation. There are also academic journals that all researchers, students and professionals alike, are encouraged to publish in. “Publish or perish” is a common mantra I heard in graduate school. Publications get you professorships, and isn’t that the goal for academics?

    Then there is the issue of egos. Everyone in academia — professors, post-docs, and students — all think they are smart. They would not be in their position if they weren’t. The trap students fall into is in trying to prove their intelligence. No longer is it enough to think you are smart; everyone else must think you are smart too. When you are in a place where everyone around you is intelligent, there is no easy measure for assigning smarts, but students find their own ways to determine it. “I come in earlier than everyone else.” “I stay later than everyone else.” “I’m farther along in my research than everyone else.” “I’m attending these conferences.” “I have X amount of publications.” If any one of these criteria are not met, students feel like they are failing. Thus starts the cycle of putting in more hours and more effort to achieve the high standard students are only putting on themselves.

    To cap it all off, each stage in the academic ladder is expensive, thankless, and rarely pays well. To be in academia, you must love it. You have to love the mundane task of carrying out experiments that, by design, are unsuccessful more times than they succeed. You have to love having every word of everything you say or write be scrutinized. You have to love being in competition with your peers — imaginary or not. Academia is brutal and graduate school is just the tip of the iceberg.

    Most of the professors I have met, don’t seem to care about this cycle. The impression I got was, “I got through it, so must you.” They are only too happy to see the experimental results come in and the journal papers be written. It secures them publications for their H-index and a cozy position at the university.

    University professors do wear many hats and are often incredibly busy. With teaching classes, advising undergraduate students, supervising graduate students, serving on committees, peer-reviewing journals, applying for grants, and conducting their own research, professors are stretched extremely thin. It is all too easy to blame them for failing to help their graduate students emotionally, but they are also running their own hamster wheel.

    There are wonderful professors out there who put in the effort to nurture their students to be successful in academia, but they are few and far between. It also isn’t entirely the supervisor’s fault when a student leaves. I had a wonderful supervisor during my first attempt at graduate school that put in great effort towards helping my lab mate and I succeed in our research. I blame my immaturity for my withdrawal. I was swept up by the imagined competition, the need to prove myself, and the daunting prospect of spending four more years on only one topic I wasn’t sure I liked.

    My second attempt was the real eye-opener. After taking a year off from academia, I switched schools, departments, supervisors, and countries for my next attempt. I will say that many things took place in my personal life that led to my ultimate withdrawal from this university, but there is also a lot to be said about the program and research environment I was in that made me decide to leave.

    This university was much more prestigious than the first university I attended and their research was much more visible. I was excited to learn from the best of the best and hopefully become one myself. In the beginning, I took in as much advice and information as I could. I paid attention to the senior students and tried to mimic what appeared to be working for them. When I transitioned into the phase of finally conducting my own experiments and presenting my own work, things started to fall apart.

    My supervisor became more distant and was extremely harsh when he did give feedback, often in the form of public shaming. I had difficulties with trying to repair broken laboratory equipment and navigating the process of ordering materials (in a foreign language) for my research. I felt like I was falling behind, so I put in more hours at the institute, arriving extremely early in the morning to get work done while the building was quiet and empty. I agonized over the presentations and reports I prepared, only to have them ripped apart or entirely rewritten by my supervisor. No matter how much effort I put in to improve, I was just left feeling stupid, incapable, and like “a waste of time.” Compound that with the issues I was facing in my personal life, and I spiraled into a very dark place mentally. When I realized just how bad things had become and nothing was working to pull me out of the state I was in, I knew I had to leave. I felt tremendous shame for walking out in the middle of another graduate degree, but it had to be done.

    Now, months later, I am the happiest I have felt in a long time. After having initially sworn off anything related to science, I have found great enjoyment in producing my podcast, Fall Asleep to Science, and applying my prior coding and analysis experience to become a data scientist.

    I am thankful for my graduate school experiences because they helped me to understand my true passions and what I want out of my professional career. I am now aware of my natural tendencies and insecurities and am working to correct those that hinder me. I learned so many valuable skills that I will carry with me into future roles: time management, effective research strategies and experimental design, work-life balance, and networking. I am a more capable person that will continue to improve with each new experience. I fell on my face twice by quitting two graduate programs, but I am a much more self-aware person because of it.

    If you are considering graduate school, I strongly encourage you to think about your mental patterns and what motivates you. If your habits and motivations are similar to what mine were, I urge you to set up a series of checks for yourself to prevent burning out. A desire for prestige is not enough to carry a person through the highs and lows of academia. Be sure to choose a supervisor you trust and a topic you could spend years dissecting. Prepare yourself before you start by brushing up on the topics you will be expected to know for your chosen discipline.

    Academia is a great space, but it is undeniably challenging. Choose wisely and prepare accordingly.

    What were your biggest failures that led to your most fruitful growths? Did you go to graduate school? What are your mental habits?

  • The History of Genetics

    An episode of Fall Asleep to Science about the history of genetics was recently published. In this episode, listeners will hear about the development of genetics as a science, discover the four major theories on inheritance that have existed since about 450 BC, and learn about the major contributors to our understanding of genetics. This episode journeys through time to learn how the human genome was first sequenced, then explores chromosomes and the cellular stages of reproduction in meiosis and mitosis.

    Listen on Spotify, Apple Podcasts, or Amazon Music, or read a sneak peek of the transcript below.

    Genetics is all about the fundamental basic principles of inheritance, including what they are and how they come about.

    It is the Science of Potential, the transfer of biological information from cell to cell, parent to offspring, and generation to generation.

    Genetics is concerned with why and how biological information transfers, because biological information transfer is the basis for differences and similarities recognized in groups of living organisms

    Genetics explains the physical and chemical nature of biological information and asks,

    ● What are the sources of genetic information? And

    ● What are the differences?

    To put the study of genetics into perspective, the pedigrees of animals and plants started 6000 years ago with initialization of breeding regimes. In fact, the oldest known genetic records are on horses…

  • What is Astrobiology?

    For centuries, humans have asked questions such as:

    Where did we come from?

    Are we alone?

    Whither are we going?

    Why am I here?

    If you have ever asked yourself any of those questions in any form, you may be a budding astrobiologist.

    Throughout history, famous philosophers have asked themselves the big questions listed above, but there has never been an adequate way to empirically address them — until now.

    Astrobiology is a growing field that is garnering more and more support. Private organizations, such as the Blue Marble Space Institute of Science and the Mars Society, host communities of scientists exploring questions related to the origins of life and the future of life in space. NASA has a division dedicated to astrobiological research, and conferences like AbGradCon are popping up to grow the field of astrobiology.

    So, what is it exactly?

    Astrobiology addresses questions about the origin of life, life in the universe, and the future of life in space and on Earth. It encompasses every subdivision of science and tests the imagination to think about life from different perspectives.

    Whether you are a geologist, chemist, biologist, astronomer, mathematician, physicist, or philosopher, there is a need for you in the field of astrobiology.

    Though previously studied separately, it is the collaboration among all these disciplines that will move astrobiology further. Institutions such as the Earth-Life Science Institute in Tokyo, Japan have recognized this need and intentionally seek interdisciplinary collaborations. From the formation of planets to the bacteria in hot springs, every detail is important.

    So, if you are curious about if humans could survive on Mars or why Earth is the only planet we know of that has life, you may want to look into astrobiology.

    To get started, give this episode of Fall Asleep to Science a listen, then go look into the organizations I mentioned. Let me know what you discover!

    How did you hear about astrobiology? What do you want to know?

    Do you know of other organizations that research astrobiology?
