Interview with
Dr. Albert H. Kwon ‘04 By Max Hui
Dr. Albert Kwon works at Boston Children’s Hospital, and is co-founder and CEO of the startup AUGMENTx. After Milton Academy, he attended MIT and Harvard Medical School. As a senior you founded Helix, so what did you have in mind?
cently there’s been interesting patent litigation about who owns the rights to CRISPR technology in human beings. Well, Milton had a couple And more societal side, there newspapers but none of them have been some interesting focused on science or engiTED talks about how people neering. There are just so view Facebook, Instagram many great science stories and other massive behavthat could spur a lot of disior-changing engines, and cussion; at the time, it was how they are making money about stem cells and about while warping our views and cool physics experiments at our behaviors. For the near CERN. We should have a way future I am interested in to talk about that and spread virtual reality and augmented the word among Milton stureality (AR) type platforms as dents, so that’s why a couple the next generation of display of friends and I got Helix technology. I’m dabbling in started. augmented reality (AR).
You mentioned that stem cell research and CERN were at the forefront of scientific discussion at that time, but what about now and in the near future? Some of the topics that interest me are CRISPR technology and gene editing. I think that’s really powerful, and rePage 4
In what ways? I have a startup incubating at Harvard Innovations lab. I’m working with a couple engineers, trying to deliver rehabilitation therapy in an (AR) environment. One problem I see in medicine right now is that, when patients lose motor functions, they have to Helix
do a lot of exercise to gradually get their functions back. I send them to a rehabilitation clinic, but then I have no clue what’s going on with them because our systems are broken. it’s so siloed: my clinic is separate, my client goes to a rehab specialist, and that’s a separate encounter; there’s nothing that ties things together. My patients tell me that exercising while at home is boring, but then if they don’t exercise, it’s not going to help them. So we’re trying to create an immersive (augmented-reality) game where we can engage the patient, and at the same time measure what the patient is doing; we can have objective data on how much therapy the patient did and whether or not they’re getting better. So what started off as a project is turning into a small, early stage startup company.
So what exactly is your role in this startup at the moment?
My official title is CEO, but it’s more than that: whether you’re CEO, CTO, CFO, no matter who you are, you’ve got to wear multiple hats, you have to be flexible to help the company. We do whatever it takes to make progress. It’s a continuous learning experience.
Along similar lines, could you talk about what you do for “work” ? The majority of my time I spend as a doctor. I am training in two different fields, so I’m in a very weird combined program where I’m going to be a general pediatrician, and a general anesthesiologist. So half the year I spend in the operating room and helping patients recover from surgery. The other half of the year I spend time in clinics. This month, I’m in the intensive care unit where severely ill children stay until they get stabilized enough to return to a regular floor. So I’m all around the hospital. And as a resident doctor, sometimes the schedule can be pretty brutal—sometimes we can work very close to 80 hours a week. So that’s my official job.
Moving away from this, what was your college experience
like in terms of getting your degrees? What sort of challenges did you encounter? I entered MIT thinking I was going to do electrical engineering, so later switching to medicine was a change for sure. Dr. Eyster’s class got me interested in biology. The class was very different from physics or chemistry. I think she was the only teacher who gave me a C on a lab report, and that opened up my eyes to a very different kind of thinking and carefulness about Helix
what I write down as my claims or my hypotheses. And that was just so eye opening to me, and the topic was just fascinating. Because MIT was heavily funding bio-related engineering research, I tried some lab research to get a flavor of that field. I decided to switch to biology and through my research experience I met a lot of medical doctors, and they heavily influenced me to go to medical school. It was the right switch for me!

Axolotls: the Potential Key to Limb Regeneration By Ariane DesRosiers
There are currently over 10 million amputees in the world, two million of whom are in the United States (1). Imagine a way in which these people would be able to regrow their lost body parts and all the resulting implications (2). Axolotls (Ambystoma mexicanum), creatures similar to water salamanders, may contain the key to solving this problem. They’re quite peculiar — with feathery attachments on the sides of their heads and beady eyes, they are not easily forgotten animals (Figure 1). Remarkably, these aquatic amphibians are capable of regenerating entire limbs without scar formation, a unique ability that makes them a focal point of
biomedical research around the world (3). Because axolotls have only 14 chromosomes (whereas humans have 46), their entire genome is being analysed by scientists (4). Axolotls contain special genes which code for proteins that allow undifferentiated cells to be sent to injured locations on the body. These undifferentiated cells (also called progenitor cells) are cells that have the potential to become different types of cells, like skin cells or liver cells. Once these progenitor cells arrive at the injury site, they differentiate into skin and tissue cells and create a blastema, a cellular structure which forms around the injury and creates the new limb (3). However, these progenitor cells
are not the only things essential to the regeneration process. Two proteins (p53 and TGF-ß1), are also integral to growing back a limb. The first of these proteins (p53) regulates cell division and suppresses tumors (5). In axolotls, this protein sends a chemical signal to initiate the differentiation of cells, turning progenitor cells by the wound into skin or tissue cells. Meanwhile, the other protein (TGF-ß1), also found in the human genome, acts as another regulator, activating nearby cells to begin the blastema formation, which gives these newly differentiated cells room to grow (3). Researchers found that if they inhibited either of
these proteins, axolotls could not regenerate their lost limbs. To complicate matters even further, multiple other compounds and cells are all necessary to achieve the limb-regeneration process (6, 7, 8).On the bright side, scientist Stephan Roy, who conducted the research on p53 and TGF-ß1 proteins, says that with enough experimentation and research, scientists might find a way to modify and use the axolotls’ to help with tissue healing, transplants and cancer cures “within the next 10 to 20 years” (3). So even though the axolotls’ potential is enormous, it will take some time before we can see that potential come to life.

However, it is not too late to lose hope entirely! You can do several things today to help the axolotls. You can donate to wildlife charities, sign petitions to the Mexican government and fishermen, or simply spread the word about the axolotls’ plight. Success stories like those of the bald eagles’, the pandas, and the North American bison show us that saving species from endangerment is possible. There is still time to save the creatures who may be the key to helping millions of people regain their lost limbs!

Unfortunately, these axolotls are dying out. Wild members of the species reside in only two canals, both of which are located in Mexico and have extremely high levels of pollution (9). Axolotls are listed as “critically endangered” according to the International Union for the Conservation of Nature (10). This alarming decrease in population can be attributed to invasive fish species, such as tilapia and carp, who compete with wild axolotls and impair their chances of survival (10). Although the Mexican government has put a lot of effort to preserve the canals’ ecosystems and protect the species,
the future seems dim for the wild axolotl (9).

Genetically Modified Mosquitoes May Be the Key to the Extermination of Malaria and Zika Virus By Minseo (Charles) Lee Mosquitoes have existed on Earth even before the birth of mankind. Researchers found a mosquito fossil that contains the blood of an unknown creature, and after testing, found out that the fossil dates back to 46 million years ago (1). These mosquitoes that have survived by sucking blood of numerous organisms are now a great threat to mankind. They serve as vectors of various viral diseases. Mosquitoes are the primary reason for the transmission of deadly virus including yellow fever, malaria, and the Zika virus(2) (Fig 1). Therefore, finding a way to get rid of mosquitoes would definitely contribute to preventing the spread of lethal diseases. In order to prevent the transmission of diseases via mosquitoes, the United States Food and Drug Administration is considering the introduction of genetically modified (GM) mosquitoes with a self-destruction gene to artificially decrease mosquito population (2). There are mainly two methods to create GM mosquitoes: Oxitec’s gene transformation method and CRISPR method.
Page 8
Oxitec, an insect biotechnology company in the UK, has devised a new method for genetically modified male Aedes aegypti mosquitoes to mate with female mosquitoes. Only female mosquitoes bite humans and among them, Aedes aegypti mosquitoes transmit diseases such as dengue, Zika, chikungunya and yellow fever (3). The GM mosquitoes contain an antidote inside their genome that allow them to survive in the wild, but it cause their offspring to die (4). These mosquitoes target one species only, and are thus expected to cause minimal damage to the ecosystem, compared to pesticides that damage the biosphere nearby. Oxitec has already created mosquitoes with fatal genes and has succeeded in decreasing the number of mosquito larvae in several regions; therefore, positive impacts are expected from this new technology. In addition, the company controls pests without using insecticides by using genetically modified insects. The method is more effective and environmentally friendly than insecticides. (5)
Helix
Another method, called the gene drive, is a method that allows specific species to have particular genes. Gene drive is an artificial method that increases the possibility of a gene to be passed on to offspring (6). This technology was invented by Dr. James of University of California Irvine. In specific, this technology spreads genes into forest mosquitoes that result in sterility, thereby completely exterminating a specific mosquito species. The extermination is done by using a gene editing system, CRISPR(Clustered Regularly Interspaced Short Palindromic Repeats)-Cas9, which is intended to insert a specific mutation into a gene and copy the same gene multiple times (7). Scientists insert a gene that creates a mutation within, and use nuclease (an enzyme that divides chains of nucleotides into smaller units) to copy the identical gene. This gene causes mosquito larvae to die before growing to be adult mosquitoes, thereby not being able to bite humans. Research reveals that the technology is effective; about 99% of genetically modified male’s offspring received added genes (8).
Although there are many positive expected outcomes, there are concerns as well. Because mosquitoes have existed for such a long time, they have co-evolved with numerous species present on Earth; mosquitoes serve as a pollinator for plants and prey for predators (9). Furthermore, these genetically engineered mosquitoes could disrupt the ecosystem from a long term perspective. Mosquitoes are arising as a huge problem all around the world, but people should be cautious before taking action to control the mosquito population. The extermination of mosquitoes is not merely just an extinction of a single species, but it is an issue that is intimately related to the public health of mankind.

The Commercial Space Race and the Breaching of the Final Frontier By Antoine Wiley
Launching a rocket into orbit is a massive undertaking. An individual launch can run anywhere from tens of millions to nearly a billion dollars, and success isn’t guaranteed[1]. Even if the launch doesn’t result in a catastrophic explosion, the rocket can’t be used again, resulting in a colossal waste of resources. This lack of rocket reusability has greatly limited the rate at which NASA, the U.S. Military, and humanity as a civilization can send things into space. Or at least that’s how things used to be. Commercial players have burst onto a multi-billion industry
traditionally dominated by government agencies and forever changed the launch equation, leading to dramatic cost cuts and a sharp uptick in launch rates. The most prominent of these companies are SpaceX and Blue Origin. SpaceX, founded in 2002, made history only six years later in September 2008 when its Falcon 1 rocket became the first privately developed liquid fueled rocket to reach orbit, which went on to become the first rocket of its kind to deliver a commercial satellite to orbit the following year [2] [3]. What makes SpaceX so revolutionary and successful is its focus on reus-
able rockets. If we could reuse rockets as effectively as we do airplanes, the price of access to space would plummet dramatically. And that breakthrough is getting closer and closer; in December 2015 the Falcon 9 landed upright at a launch facility after having delivered 11 communications satellites into orbit, a historic first [4]. But SpaceX isn’t the only new player in the market. Aerospace titan Blue Origin, helmed by Amazon CEO and world’s richest man Jeff Bezos, has many of the same ambitions as SpaceX and its own trophy case of spaceflight milestones; the rocket booster of a New Shepard
rocket (the company’s standard rocket) landed on Earth on November 23, 2015, marking the first time in history that a rocket booster went to space and back [5]. And although these companies’ lofty goals of daily launches and Martian colonization still remain out of reach, the effects of these efforts are already clear: prices have dropped drastically relative to even a decade ago. The trend only continues with each breakthrough, the most recent being SpaceX’s successful test launch of the Falcon Heavy, the most powerful rocket in operation “by a factor of two” [6]. The rocket can launch a staggering 140,660 pounds of cargo into low-Earth orbit at a price tag of $90 million dollars, which works out to a jaw-dropping
$639.84 per pound [7]. To put that in perspective, United Launch Alliance Delta IV Heavy is seven to twelve times as costly [8]. The trend is only going to gain momentum as rocket manufacturers learn to more capably recover their rockets and refurbish them for the launch pad. Recent rocketry advances are certainly worth celebrating, but our growing proficiency at spaceflight raises many issues. Companies like SpaceX and Blue Origin think of space as more of a playground for human activity, while NASA and other government agencies have a far less hands-on vision, and nothing more sharply highlights this difference
than Mars. While NASA plans to eventually send astronauts to Mars in the future, the agency’s current ambitions are to studiously examine the planet for signs of life, carefully sterilizing each spacecraft it sends to the red planet in order to prevent contamination from terrestrial microbes, while SpaceX intends only to colonize and ultimately terraform Mars to render it more habitable. Just one rocket from SpaceX would irreversibly change the microbiome of Mars, abruptly shattering the research aims of thousands of scientists. The extent to which which we should interact with space remains an open question, one we will end up having to answer sooner or later.

CRISPR and Pigs:
How We Could Solve Organ Needs By Kiran Biddinger
winner of the Laurence S. Persky Award 2017-18
Figure 1: The hallway of the eGenesis, a lab dedicated to perfect the technique and practice of xenotransplantation so that it can become common medical practice. Every 10 minutes, someone is added to the national transplant waiting list. Every day, 20 people die while waiting for an organ donor. As of October 2017, about 116,000 people were currently waiting for organ transplants (1). However, simply not enough human organs are available to help these people: At that same point in 2017, only 26,000 transplants had been carried out for the year, with 12,000 donors (1). One suggestion to fix this shortage was xenotransplantation, the “transplantation, implantation, or infusion” of non-human or animal cells, Page 12
tissues, or organs into a human (2). Pigs seemed to be a possible solution for viable organs, as their organs can grow to roughly the same size as humans’. However, pig to human transplantation was ruled out after the discovery of PERVs, or porcine endogenous retroviruses. These retroviruses are seemingly harmless to pigs, but they can become active and cause fatal problems with humans (3). Thus, pig organ transplantations were seen as useless, until CRISPR Cas9 was discovered. CRISPR Cas9, which stands Helix
for Clustered Regularly Interspaced Short Palindromic Repeats, is a technique that allows scientists to make changes at specific locations in the genome through the following process. “CRISPR ‘spacer’ sequences are transcribed into short RNA sequences” to find specific sequences of DNA (4). CRISPR utilizes a guide sequence of RNA that is complementary to the target region of DNA and an enzyme called Cas9 (4). The guide sequence of RNA binds to and brings the Cas9 to the target region (4). Then, the Cas9 enzyme binds to and cuts the target DNA
(4). Intended to treat genetic diseases in humans, CRISPR allows scientists to fix genetic mutations (4). For pigs, the idea was mostly the same: Scientists would use CRISPR to remove the genes causing the retroviruses, so the retroviruses would not be able to harm humans. A company that focuses on this process of making organs that could be transplanted into humans was founded in 2015 by Harvard geneticists George Church and Luhan Yang (5). Later in 2015, they found that they could use CRISPR to deactivate all 62 PERVs in pigs, bringing modern science even closer to xenoplantation (6). Because it would be very
difficult to remove the retroviruses from already living pigs, the scientists decided to pursue the goal of breeding their own pigs without the retroviruses. They were able to breed and nurture real live pigs who seemed to have no trace of the PERVs (6). Therefore, pig organs could be transplanted into humans without activating the retroviruses in order to keep the transplantee safe. However, that discovery does not mean that xenoplantation is tested and ready for action. Still other problems loom, such as figuring out a way to prevent the human body from rejecting a pig’s organ (3).
Nevertheless, even if xenotransplantation became both achievable and acceptable, doctors would have to decide who would get the privilege of human organs: should it be people with religious objections, wealthy people who can pay more, or people picked in a random lottery? Pigs organs would very likely be inferior to human ones (7). Someone would have to create a policy as to who gets the human organs, which would likely be preferable to pigs. So, watch as modern science gets closer and closer to being able to transplant pig organs into humans: both the scientific and moral battles.

Why the Dinosaurs Became Extinct:
New Discoveries By Charles Sloane
Over the summer of 2017, places around the world experienced darkness due to the moon passing in front of the sun, known as a solar eclipse. This eclipse was an interesting phenomenon to watch, but would it have been favorable if that darkness lasted for about two years with our world falling apart around us? Sixty-six million years ago the world remained dark for as much as two years with massive consequences once an asteroid hit Earth. An asteroid collided into Earth at the Yucatán Peninsula. This location is possibly one of the worst places it could have hit. The geology of this place shows that the sedimentary rocks were extremely dangerous and unlucky to the life on Earth (1). There have been many hypotheses around the mass extinction of the dinosaurs. Until a recent drilling project, very little was actually known about why the dinosaurs became extinct. The main recent hypothesis is that this extinction was extremely rare and against all odds, as supported by the drilling project (2). A location on Earth that could cause such a catastrophic extinction from an asteroid such as the one that hit the Yucatán Peninsula is extremely rare. Page 14
Only thirteen percent of the planet possesses the surface rocks that can cause a mass extinction from a similar asteroid (1). Other large asteroids have hit Earth without mass extinctions such as the one that hit Chesapeake Bay because the area did not have the specific sedimentary rock (3). It, therefore, did not cause a major extinction even though they were similar in size. If the asteroid had hit most anywhere else on the Earth, we might be living in a world populated with dinosaurs to this day (4). The reason why the spot where the asteroid struck caused a mass extinction was the sedimentary rocks that lay below. A sedimentary rock called evaporite is in surplus in certain places (Fig. 1). Evaporite forms when a large body of water evaporates leaving these deposits (5). Evaporite was rich in hydrocarbon and sulfur, and when the asteroid hit Earth, the impact heated the sedimentary rock, vaporizing it (6). Sulfate aerosols and stratospheric soot were then created which lead to drought, extreme global cooling, and the blockage of sunlight (6). The sulfate aerosols and stratospheric soot which both originated from the sedimentary rocks are viewed as causes for the mass extinction (6). Helix
This knowledge was found in a drilling project during the past couple years in the Yucatán Peninsula at the site of the crater. They went deeper than they thought could and found things that had never found before (7).The smallest amount of change in the average surface temperature of the planet that can cause a mass extinction like the one that killed the dinosaurs would be 8-10℃ (6). In the event that killed the dinosaurs sixty six million years ago, the global surface air temperature dropped between 13-17℃ (6). With the temperature lowering drastically, photosynthesis decreased greatly; the animals such as the dinosaurs that could not adapt did not survive (3). The dinosaurs could not adapt to the drop in temperature because they were cold-blooded animals which made them need heat from the sun and the air to survive, unlike warm-blooded animals (8). The main development in the never ending learning curve of the events of the dinosaur extinction is that the extinction itself was an unlucky rarity. This tragic event could have been avoided if the asteroid hit any place in the other 87% of the world, but this event lead to the world we have today (3).

A Breakthrough in STEM Prizes By Kate Jones
Every year, actors and directors are recognised at the Academy Awards, and singers are celebrated at the Grammy Awards. But what about science, technology, engineering, and mathematics (STEM) researchers? Thanks to an elite group of wealthy people in STEM fields, for the past five years researchers have been not only nominated and honored at an awards show for their research, but also monetarily compensated – as actors and singers are – to be able to continue researching. The
Google, and Mark Zuckerberg, co-founder of Facebook (1). Each year, seven researchers across the fields of life sciences, fundamental physics, and mathematics are awarded Since their inception, the Breakthrough Prizes (1). AddiBreakthrough Prizes have tionally, the same organization revolutionized the way STEM awards New Horizons Prizresearchers are recognised es, which are smaller prizes and celebrated. Yuri Milner, a awarded to up to six new well-known technology invesresearchers who show promise tor, used his wealth to help advance STEM fields by found- in their fields (prize website 2). ing the Breakthrough Prize The Breakthrough Prize at its along with an elite group in core differs from the Nobel the STEM community including Sergey Brin, co-founder of Prize in that it honors younger Breakthrough Prize gives those involved in STEM a chance to receive the public recognition that singers and actors receive.
researchers who have already shown promise, gives them the financial means to make more discoveries, and recognises researchers for coming up with hypotheses even if they are unable to further research them yet (1). The Breakthrough Prize also celebrates researchers in mathematics as well as other STEM fields, unlike the Nobel Prize (3). One of the 2017 Breakthrough Prizes was awarded to mathematician Jean Bourgain for his research in a further application of the Pythagorean theorem (3). Jean Bourgain, born in 1954 in Belgium, attended the Free University of Brussels, where he earned a Ph.D in mathematics (4). He won
a Fields medal, a very prestigious award in mathematics, for his wide range of research and proofs (britannica 4). Although Bourgain received the Breakthrough Prize for all of his research and discoveries in mathematics, a major factor in his winning was his recent “decoupling theorem.” This theorem takes the general ideas put forth by Pythagoras of comparing triangle side lengths to the hypotenuse length and applies them to the superposition (adding together) of waves such as radio or light waves (3). Bourgain’s connection between the Pythagorean theorem and the superposition of waves (3) highlights his mathematical style of applying concepts
from various fields of mathematics to proofs (4).

Every year, the Breakthrough Prizes honor STEM researchers such as Bourgain and give them the recognition they deserve along with the monetary resources needed to continue revolutionizing STEM fields. The annual Breakthrough Prize serves as a wonderful celebration of all the revolutionary work that STEM researchers do by reminding the world that STEM researchers are celebrities too.

Q: What is your area of STEM that you work in or are interested?
Q: What will your major/focus area be in college?
Interviewed by Zan Huang
A: Computer Science and Software Engineering. I’m also interested in cybersecurity, but I know less about it than I do software engineering. I have been programming since I was in 6th grade and I have taken a couple of programming classes at Milton. I program a lot for fun in my free time, and I plan on studying computer science at Whitman College. Q: How has programming class at Milton changed your skills or interests? A: Well my artificial intelligence class has definitely clued me into a lot of stuff I never heard before
Interviewed by Ariane DesRosiers
and helped me narrow what I am actually interested in studying in computer science. Through studying artificial intelligence this year, I have learned that I don’t really like artificial intelligence as a field. That was helpful for me so that in college I can study what interests me. Q: What got you into Programming? A: Well my Dad worked for IBM as a lawyer, but before then he was into computers, back when computers were very new. In college he majored in management science because that was the department of the school where they had the best computers and the best access

A: I think I first became interested when I was maybe in third grade or so. In a science class I saw a human body model that the middle school was using and was shocked that the body could be so complex. And then as I grew I learned more about geology, chemistry, evolution, biology, etc. During my time at Milton, I chose to take the electives of Neuroscience and Anatomy & Physiology.

A: When I was applying, I put aerospace engineering down, but now I’m not quite sure; I think I might do aerospace engineering or maybe computer science. Q: Did any specific teacher/friend/ scientist inspire your passion for science?
Q: What college will you attend?
A: I think the two teachers that most inspired my passion for science have been Ms. Lillis and Mr. Edgar, who taught me for Honors and Advanced Bio respectively. Their passion when teaching the material really sparked my interest in biology, an interest which only continued to grow the more I learned.
Q: How did you first become interested in science and how did you explore your interest in science?
A: Harvey Mudd!
A: I’ve always been interested in astronomy and the solar system. So, in the summer after freshman year I did a program in astrophysics at Johns Hopkins (through the CTY program) and then I came to
the realization that I wanted to do something more applied, something where I could look at and see the full outcome of my work. Q: What is/are your DYOs this year? Favorite DYO from Milton? A: My favorite is either my Chemistry DYO or my Advanced Physics DYO. In Chemistry last year, I definitely had a lot of fun writing up my lab report on the Briggs-Rauscher Reaction because there’s not that much information on the internet about this reaction, so it felt like I was doing a lot of original research. For my Physics DYO, we built an ion thruster that would be used in spacecraft. Writing the lab report was slightly harder, but I had too much fun to think about writing the lab report.

My partner and I first classically conditioned planaria by pairing light exposure with a brief electrical shock (which they contracted in response to) so that the planaria learned to associate the light with the shock to the extent that they contracted in response to just the light. We then severed the planaria directly below the head or a bit above the tail, generating head-less and tail-less planaria segments. After, we tested the response of regenerated planaria to light and found that all of the

Interviewed by Charles Lee Q: What will your major/focus area be in college?
A: I’m thinking about majoring in computer science, economics, and/or statistics. I’ll do some combination of the three — a triple major may be ambitious, but it’s a possibility. I could end up with a minor in one or more of the above instead.
A: Something to do with computer science or data science. I’m not exactly sure what that would look like but there are a lot of options.
Q: Are you going to have any minors? A: I am considering minors in either Finance or Computer Science. I haven’t really done any work in those areas but I know that in the long run, having some knowledge on them would be valuable. Q: Interests for after college?
A: I’m not really sure what I would want to do after college. As of right now, I am leaning towards becoming an engineer, focusing on designing and creating prosthetics. This may lead me to the MIT Media Lab, where they are currently focusing on prosthetics in the ankle area. Another possible route would be going to medical school. Q: Why do you like science? A: I like science because I like to understand how the world around me works. Through science, I can learn about why everything is the way it is, but it also gives me the opportunity to apply what I know and try to make sense of things on my own.

Q: How did you first become interested in science? A: One of the first ways I became interested in science was by collecting rocks as a child. Having gone to Brazil frequently, I had easy access to a plethora of rocks. From there, I became interested in how one rock differed from another and why it would be more valuable. I would read about their properties and just try to understand how they all compared to each other.

A: Electrical and Computer Engineering Lab. I was helping on a project funded by the Department of Defense. We were working with an injectable nonmaterial that prevented blood coagulopathy. This medicine was originally targeted for soldiers on the field to temporarily help them until they can reach a better medical institution; however, the hope is that it can also be used in other settings, such as in ambulances. During other vacations, I have joined volunteer organizations which visit remote locations in need of health care.
Tyler Carlton A: I will be studying biology, but I do not have a concentration in mind yet. Q: Has any teachers inspired your passion for science? A: Although they did not spark my interest in biology, my Junior year science teachers (Mr. Edgar and Mr. Bingham) played a fairly large role in helping me make the choice to pursue a career in STEM.

Q: What is your favorite exhibit in the Museum of Science? A: I have always liked science but my experiences in the last few years at school and outside of school have made me even more excited about science. At Milton, I loved Chemistry Honors class with Mr. Moore and my Advanced Physics class with Mr. Kernohan this year. Over the past few summers I interned at a cancer research lab and worked at an electrical engineering lab building a circuit to improve EEG systems.

Q: What will your major/focus area be in college?
Q: What college will you attend?
Advanced Physics. We created versions of Bhaskara’s Wheel, a type of perpetual motion machine, and analyzed the physics behind perpetual motion.
Q: What college will you attend? A: While on vacation with a friend, I read an article about stem cell regeneration and its wide-ranging possibilities and I found it to be very interesting. At that point in time, I did not really explore science much further beyond a National Geographic magazine or two. Now, four years later, I find myself watching informational science shows and reading about random college experiments when I probably should be working on my Senior Project.
A: Harvard University. Q: How did you first become interested in science and how did you explore that interest? A: I used to read a lot of science books for kids, and in middle school I started reading journalism articles and science books for the general public. Q: What do you like about science specifically at Milton?
A: I really liked Honors Biology because I really enjoyed the problem-solving nature of the thinking. I also really liked Advanced Biology; I’ve improved so much in my ability to think of a question and design an experiment around it. Q: What science electives did you take and what was your DYO? A: I took Advanced Biology and Neuroscience this year, and my DYO in Advanced Biology was about planaria and the effect of ethanol on their head regeneration. Ethanol is hypothesized to work on brains through raising the activation of a specific protein, and in our DYO it showed that ethanol worked in planaria in part by raising the activation of that protein.

Q: Have you done any internships or held any jobs in the field of science? A: I worked in a lab at Dana-Farber for the past two summers under a grad student. I was helping him study a particular protein, and we’d sit down at the end of each day and debrief what I did and the science behind it. I had a ton of fun; everyone in the lab was willing to talk to me and help me out.

Q: Why do you like science?
A: This year in Organic Chemistry we didn’t have a regular DYO, but we did have an assignment where we chose a bioactive molecule to research and present on. I chose testosterone, and I enjoyed the project a lot. My favorite DYO from Milton would probably be last year in Honors Biology. I put translucent flies in ethanol and measured the change in the flies’ heart rate. I came up with a mechanism to be able to look at the flies under a microscope. Counting the heartbeats was very tricky, but when I finally came up with a good design the experiment was a lot of fun.
