These Past Weeks Sure Flew By by Jessie Jin

Time flies when you’re having fun! I can’t believe I am already approaching Week 6 of TRIP. The past few weeks, I conducted my kickoff experiment examining the effect of valerian and constant darkness on female fertility. Using the female fertility assay, I quantified the number of embryos per female and the % hatching of embryos. More embryos per female and a greater % hatching indicate that the females are more fertile and produce more viable offspring. My results indicate that both valerian and constant darkness increase female fertility. However, I was surprised to see that many of the flies in the constant darkness vial died after the first 7 days, thus indicating the negative effects of a disrupted circadian rhythm (sleep/wake cycle). By combining valerian and constant darkness, not only did female fertility increase the most, but some of the negative effects of constant darkness were also ameliorated. Besides collecting data for my assay, I also learned how to collect developmental data by looking at the total number of pupal cases and then calculating the % eclosion (empty pupal cases/total pupal cases).

Picture
In addition to learning basic lab skills such as making fly food, making grape plates, and sorting flies using CO2, I have seen how science is a process of trial and error. Sometimes you lose a couple of flies when transferring flies between vials or have difficulty distinguishing between an unhatched embryo versus a larva — and that’s ok. Some skills are harder to master at first such as sorting flies efficiently. However, I believe with practice, I will be sorting flies quicker in the coming weeks. Since the moment I stepped into the lab about 5 weeks ago, I have definitely grown as an aspiring scientist. For this, I am grateful for Dr. Purdy, Dr. Leystra, the TAs Austin and Keith, and my TRIP classmates.

Looking ahead, for my independent project I am interested in comparing the effects of red yeast rice versus CoQ10 on overall health due to a personal connection to this topic. CoQ10 is a dietary supplement that helps improve heart health. My uncle takes various dietary supplements including CoQ10. After finding out that CoQ10 can be derived from red yeast rice, which is found in fermented red bean curd and other Chinese foods, I was curious about whether my uncle could eat foods with red yeast rice instead of taking CoQ10 tablets for similar health benefits. I look forward to examining this question in the coming weeks.

Recent Fruit Fly Findings by Ethan Kang

Hi again, readers! These past few weeks have flown by quicker than fruit flies escape from the vials—and all of my TRIPmates would certainly agree that they’re pretty quick. But in all seriousness, I’ve had a lot of fun creating solutions, sorting fruit flies, presenting to the class and performing behavioral assays. My fantastic peers have certainly assisted me along the way and I have enjoyed getting to know them a little bit more. ​
Picture
Fruit fly development has also been a blast to watch and since I absolutely enjoy counting birds, counting the number of pupae in a fly vial isn’t much different. Similarly, contrary to the reaction of some of my peers, I was delighted to have the opportunity to sort fruit flies into specific quantities. I enjoyed picking out the details between male and female flies, noting particular postures and field marks, just like with bird identification.
Picture
For my introductory experiment, I determined how the yellow flower typically used for depression, St. John’s Wort, along with head trauma, affects anxiety levels in the flies. Using my newly acquired knowledge about making solutions and inducing head trauma, I inflicted these onto my flies. After waiting a few weeks, I performed the open field test assay, measuring how anxious flies generally gravitate toward the edge of a container while unconcerned flies generally stay toward the center. I concluded that flies with St. John’s Wort were less anxious than those with head trauma. Interestingly, the St. John’s Wort flies seemed to develop slower than the rest.

 I decided to research how monosodium glutamate (MSG) affects fruit fly fertility
Now for the thing that’s been on my mind for nearly half a year now—my independent project! After a bit of deliberation, I decided to research how monosodium glutamate (MSG) affects fruit fly fertility. MSG has been involved in much of the average person’s daily diet, including my own. As a common ingredient in many diets, MSG has been subject to many conflicting studies about its true effects on your health. As a result, I plan on testing their fertility while recording developmental data. I’m excited to see how my results turn out and if I can help contribute to the MSG debate scientifically!

It’s hard to believe we’re almost halfway through the program already! The past few weeks have involved a lot of learning, experimenting, and collaboration. It’s also been really enjoyable getting to know everyone more!
Picture


​For my kickoff experiment, I investigated how ginkgo biloba and head trauma affect fly mood through the social space assay. I sorted flies on ice, put them in social chambers, and analyzed their distance using ImageJ software. I enjoyed putting my results together and the feedback I got while presenting it was beyond helpful!
Picture
For my independent project—after spending quite a while trying to sift through my ideas, I finally settled on noise pollution and its effects on overall health. Noise pollution is a major problem, especially in cities, that many people don’t even realize exists. It’s often overlooked because it’s not a tangible form of pollution the way air and water pollution are, but it’s pretty important as well! I experienced it a bit when I did a summer camp in the city. To me, it wasn’t too much more than an incredible nuisance, but studies show that, long term, it has adverse effects on sleep, stress, blood pressure, and more. Last time I was in the lab, we were working on fine-tuning our proposals for our independent planning projects. After a lot of planning, planning, and more planning, I now have a pretty solid idea of what I will be doing! I will be using the female fertility assay and also analyzing developmental data which will allow me to observe effects on oogenesis, spermatogenesis, embryogenesis, and overall health. ​

I finally settled on noise pollution and its effects on overall health
Next Saturday, I’ll be officially starting my project. I can’t wait to get started! Thanks for following along so far, and I’ll be back with more updates in no time!

Week ???? at TRIP by Ryan Parsaee

​Hey everyone! I think it’s been a couple weeks since my last update so I have a lot to tell you! Firstly, I have been having so much fun at the lab, it's like no other really. I have really learned a lot about what it is like to have a career in the laboratory, and it is very engaging! Another unique aspect of this experience has been watching the flies grow in real time and watching your data as it changes, so cool. 

​
I am finishing up my kick-off experiments, which, if you do not remember, focused on the effects of Ginkgo Biloba as a medicinal tool to treat brain damage. To do this, I treated the flies to a negative geotaxis assay, which generally measured their brain activity, as well as taking developmental data. Surprisingly, Ginkgo Biloba is an excellent brain healing tool!
In terms of my independent project, I am interested in the effects of a relatively new drug. Kratom. It is an opioid adjacent substance whose research is very limited. From what we know, it acts as a stimulant at low doses and as a inhibitor at high doses, it also demonstrates the common pitfalls of opioids, its addictive nature, contribution to liver failure, and permanent neurological damage. I believe that researching Kratom on flies can provide a translational red flag for more research that can hopefully build into conclusive data regarding higher order animals such as primates or humans. ​

The Path Forward Has Been Lit by Shiven Patel

The first few weeks in the program have flown by swiftly. However, reflecting on the past few weeks has shown me how much I have learned. We are only halfway through, and I have grown much as a scientist and person! The program has taught me how to analyze data, work with fruit flies, and, most importantly…work through new and challenging situations through problem-solving! Critically thinking about a problem can offer a unique solution that may not be as obvious at first sight! Additionally, throughout the first few weeks, I have connected with the other TRIP professors and members, making meaningful friendships.   
Picture
    In the first couple of weeks, we worked on our own introductory experiments to familiarize ourselves with the techniques, the flies, and the assays required in the lab. Specifically, my introductory experiment analyzed how Holy Basil, a drug known to have protective digestive effects, coupled with Intestinal Inflammation, affects Fruit Fly Motility. Throughout the experiment, I learned to use micropipettes, knock out the flies, and effectively collect and present data. Now it is time to develop my own Independent Project!
    Just like many other teens and adults , I am a student who spends most of my time in and out of school looking at computer screens. With the recent pandemic and growing technological age, students and adults worldwide spend increasing amounts of time on phone and computer screens emitting large quantities of blue light. The amount of time spent on phones, computers, and television will continue to grow! One of the known effects of large amounts of exposure is a decrease in eyesight, but what other harmful effects can blue light have? 
Picture
  My interest in blue light prompted me to analyze the effect of long-term exposure to blue light on adult memory

Picture
My interest in blue light prompted me to analyze the effect of long-term exposure to blue light on adult memory. I plan to expose fruit flies to increasing amounts of blue light and quantify their memory through the Adult Memory Assay! The Adult Memory Assay consists of negative reinforcement tasks where the flies are exposed to one scent, which they associate with a negative action, and another scent, which they associate with a positive action. I am hopeful this experiment will be successful in the coming weeks and reveal something about the long-term effects of blue light. In the coming weeks, I will record data and perform my experiment! I will keep everyone updated! See you in a little.

More Fly Lore... by Endy Ascencio-Miranda

There is a lot of catching up since the last blog post. From setting up my first practice experiment, to presenting said information, and now finally creating my own experiment - things are cooking up fast. I’d like to mention that I have been beyond grateful for this journey through TRIP so far. I’ve grown so much as a scientist, mainly because of the amazing instructors and TA’s along with the amazing people who I grow alongside with. First let me tell you about my first experimental question, “How does St. John’s wort and circadian rhythm affect mood?” 
This initial experiment was exciting to run. It was fascinating to perform the “Social Space Assay” which places fruit flies in small social chambers. The closer they are the more “sociable” they are and vice versa. Although presenting this information was a different story… Personally, I’ve never been the greatest presenter and that’s not something I’m ashamed of but I received helpful feedback to hopefully improve my presentation skills.
Picture
Other than that I finally get to create my own experiment. I’d say the hardest part was actually creating one, at first I really thought I had a great idea but it turns out that it wasn’t good enough. Luckily I was able to come up with something. As of lately I haven’t been able to fall asleep without the sound of my fan. This then led me to think about White Noise along with the different colors of noise. Different colors of noises have different properties ranging from frequencies to amplitude. This led me to wonder which sound would be the best for memory. In order to test their effectiveness I will perform the larval memory assay, where I would condition larvae to associate a smell with a sound. Then I would create two sides, one that is conditioned and the other not conditioned to see if the larvae remembered the sound. That’s just a barebone explanation of the assay but I just can’t wait to see the results!

Growing Fond Of The Fruit Flies... by Anoosha Shukla

Hi everybody! Sitting in the lab right now. Counting up some pupae. Loving this developmental data collection. I truly savor every moment in the lab: soaking up knowledge from the instructors, TAs, my labmates, and of course, the fruit flies.

Picture
What have the flies taught me? They have taught me patience and persistence. No matter how many times I go over the female fertility assay steps in my head, flies manage to escape from every single vial. But, I feel myself getting better at working with flies. Now, I can sort flies faster and differentiate embryos from poop using a dissection microscope!
In all honesty, I did not think I would love fruit flies this much. I especially enjoyed the kick-off experiment and presentation. I looked at how black cohosh (a plant native to North America) and a high sugar diet affect female fertility. Just from four weeks of a kick-off experiment, I already feel more confident in my lab skills and communication skills. I found that black cohosh increased female fertility while a high-sugar diet decreased female fertility. Presenting my findings to the class was a rewarding and insightful experience. The TRIP environment is supportive, yet always challenges me to improve. ​
Picture

After everyone’s amazing kick-off presentation, we got started on independent project brainstorming. To give some context for my decisions, note that I have hyperhidrosis in my hands, meaning that my palms are always sweaty. Smudged pen and damp papers have always been victims. Handshakes are my worst enemy. When consulting a doctor about my condition, I was prescribed an antiperspirant with aluminum compounds. The doctor was hesitant about this option, given the recent controversy of aluminum as a carcinogen. However, there are no non-aluminum antiperspirant solutions to palm hyperhidrosis, other than a botox injection! Aluminum compounds in deodorant and antiperspirants have spiked controversy due to the concern about it causing breast-cancer by increasing levels of estrogen.It is not just found in MY prescribed hand antiperspirant though. Although non-aluminum deodorants exist, many of the popular brands and aerosols used by people daily have high amounts of aluminum. Given this controversy, I want to research the long-term effects of aluminum compounds found in antiperspirants on female and male fertility. ​

 I want to research the long-term effects of aluminum compounds found in antiperspirants on female and male fertility.

After discussing my project with Dr. Purdy, I grew even fonder of my research idea. We had to adjust many things but landed on a solid and feasible topic. According to our planning calculations, due to the flies' fast reproduction rate, I will be able to conduct an assay on two grandchildren! How cool is that?! This means I will have to be extremely organized in my processes so I do not accidentally mix up generations. I am most excited to see the results of this study as it directly impacts my health and many others. I am also excited to see my labmates' projects. I enjoy spending my Saturdays with them and look forward to hearing about their interesting independent research projects!

Kickin' Off Onto Fly Sleep Deprivation! by Daniel Lee

4/24/2023

Hey again everyone! It's already Week 6 and I'm back to tell you all about how my kickoff experiment went! Lot's of new knowledge has flooded my brain but I'm lovin’ it! From staring at small, wriggling larvae to creating grape plates, I've learned so much in the short amount of time I've spent at TRIP. Ah right, the kickoff experiment! To recap, I looked into how Valerian and a high sugar diet affect fruit fly anxiety levels. I conducted the Open Field Test, an assay measuring fly distance traveled and amount of time spent near the center of assay, all in order to determine fruit fly anxiety levels. 
Picture
From my results, all of the flies seemed to be really anxious. I guess that's what you get when you constantly hover over them and constantly knock them out! That's what practice is for, right? All in all, the kickoff experiment was loads of fun. It was definitely a challenging, and very rewarding, experience. It helped me to get more experience on my lab skills, such as pipetting and my ability to handle the fruit flies (we won't talk about the ones that escaped). ​
Picture
Picture
Now that we've finished with the kickoff, we're heading onto the independent experiment! For this endeavor, I am looking at the question of "how does sleep deprivation affect fruit fly social avoidance?" I am asking this question since I am very interested in sleep deprivation (totally not because of personal experience) and the relationship between sleep deprivation and stress. Oftentimes, high stress can lead to sleep loss which, in turn, can worsen physiological stress responses. It's similar to a positive feedback loop in which the cycle just keeps on spinning! I also am really interested in the concept of fight or flight and how stressed flies could possibly give different responses when compared to control flies. I plan on trying to test out that concept through my experiment with stress signals, more specifically the dSO hormone, acting as a possible trigger for the ‘flight’ mechanism. Along with ‘flight’ is ‘fight’, which entails rewards aka a mate, a female fly in this case.
I wouldn't say that it's all set in stone yet, but I'll make sure that I fill you all in next time. Hopefully I can gather some delectable data! See you all in a bit!

Flying Through TRIP by Ishani Bansal

Hey guys! A lot has happened since my last update! For starters, I completed and presented the kickoff experiment. I was testing how fenugreek and a high sugar diet affects female fertility. I learned that fenugreek increases female fertility by A LOT, about 5 embryos per fly to be more precise, and a high sugar diet decreases it. However, I learned so much more than that. I realized that I have to be really gentle when separating flies otherwise I accidentally decapitate them. I should also create a better system for counting flies. Also, I found that it’s important to learn what an embryo looks like, so you don’t mistake it for some yeast. As far as presentations went, I had the “fortunate” opportunity of going first in my group. Luckily, everyone was really supportive and asked me amazing questions about my project. 
The next week, we split up into two groups and planned out our independent projects. I originally came up with the idea of studying iron and turmeric powder’s effects on development and female fertility. However, I’m currently in the process of editing my question, because I realized that I wasn’t too interested in studying that. I’m considering studying the effects of turmeric powder on fly mobility, since I feel it’s more novel and related to me. I’ll most likely use the negative geotaxis assay. On that day, I also got an opportunity to talk to some of my TRIP friends about their personal lives. I had a blast listening to conversations on school, future plans for college, and grievances about homework. I realized that I have so much in common with my TRIPmates, besides the fact that we are all interested in science.

TRIP has been such an amazing experience so far, and I can’t wait to see where I go with my independent experiment. I’ll let you all know how my experiment works out, but for now I have to do some more math. Until next time, everyone!

MY Trip Through TRIP by Venkat Devabhakthuni

Over the past 5 weeks, I've been thoroughly enjoying TRIP and eagerly looking forward to my Saturday mornings when I get to come into the TRIP lab. Working alongside Dr. Leystra, Dr. Purdy, the TAs, and my fellow TRIP-mates has been an amazing experience. I've gained valuable skills in micropipetting liquids,sorting fruit flies, and running experiments over the past three weeks. 
Picture
Picture
We are currently at the midpoint of our TRIP program, having completed 5 weeks, and it's been quite an eventful ride so far! Personally, I've been focused on my introductory project, exploring the impact of soap and vitamin D3 on fly motility. My study involved using vitamin D3, known for its anti-inflammatory properties, as the drug, and soap, which gives the flies intestinal inflammation, as the stressor. In order to test the effects of my drug and stressor I used the Negative Geotaxis assay. The Negative Geotaxis assay is a commonly used behavioral assay in which the ability of insects, such as fruit flies, to climb up a vial is measured. The assay involves placing a group of flies at the bottom of a vial or a narrow chamber and then gently tapping the flies to the bottom of the chamber. The flies will then try to climb up the chamber due to their innate negative geotaxis behavior. The assay is often used to assess the effects of genetic mutations, drugs, or environmental factors on fly behavior and can provide insights into various neurological and developmental processes. Through my Negative Geotaxis assay I learned that the effects of soap outweighed the anti-inflammatory effects of the Vitamin D3. I then presented my findings to my peers and learned a multitude of different techniques that can help me become a better presenter.

The idea that finally entranced me was studying the effects of amphetamines like Adderall on people who do not suffer from ADHD
Additionally, I began working on developing my independent project. The idea that finally entranced me was studying the effects of amphetamines like Adderall on people who do not suffer from ADHD. It is important to test the effects of amphetamines on non-prescribed patients because amphetamines are a stimulant medication that potentially can be misused or abused by individuals seeking to enhance cognitive performance, increase energy levels, or lose weight. These medications have a high potential for addiction and can lead to adverse side effects, such as heart problems, sleep disturbances, and mood changes. Additionally, using amphetamines without a medical need can lead to dependence and may increase the risk of developing psychiatric disorders, such as depression or anxiety. Therefore, it is important to understand the risks and benefits of these medications, particularly in individuals without ADHD, to prevent their misuse and ensure their safe and effective use in the treatment of ADHD. I am looking forward to setting up my experiment next week, and writing to you all again!
