For my independent project, I chose to look at how starvation and intermittent fasting affects female fertility. Intermittent fasting is becoming increasingly popular among people looking to lose weight and find alternative diets that fit a flexible lifestyle, however, restricting food intake can have negative effects on overall health. For example, anorexia is a common eating disorder where an individual restricts the amount of food they eat and it can lead to malnutrition, mental health issues, and even decreased fertility when a woman stops menstruating as a result of being unhealthy.
My goal for this project is to see the short-term effects restrictive eating can have on a woman’s fertility and overall health.
So far, the first few weeks of TRIP have been informative, independent, and supportive. Planning my project was centered around what I wanted to test and what interested me the most, which is something I rarely encountered in my high school science labs. So far for my independent project, I have been able to test two seperate groups of flies by fasting them for 8 hour periods, and I am looking forward to seeing the results from the assays in the coming week.
Soon after I wrote my last post, we began getting acclimated in the lab environment with our assigned preliminary screens in which I was tasked to determine how Vitamin D3 affects flies in both light and dark conditions. As many know, Vitamin D3 is a nutrient created in the skin when people are exposed to sunlight, or can be consumed through dairy, vegetables, and fortified products. With this information, it was fascinating to see if this Vitamin could supplement flies deprived of light, or if the flies were deprived by the trauma of darkness in the first place. Once the flies were exposed to their drugged food and/or deprivation of light, I utilized the social space assay, in which I placed flies into a two dimensional glass chamber to quantify their sociability by measuring the distance between each animal. Through this screen-- my first ever lab screen at that-- I was introduced to a variety of techniques and programs that I thought I would never be able to use until later on in my career, affirming my love for research. This made me even more excited to begin my own independent project!
As stoked as I was to begin my own study, I encountered a couple bumps in the road that made things just a bit more complicated (or exciting-- it depends how you want to look at it). I initially thought that I wanted to test how soy milk in comparison to other milks affects female fertility in flies. Soy contains a compound called phytoestrogen, a fancy term for a substance that makes the body believe it is estrogen. If consumed in large amounts, soy isoflavones, the phytoestrogens in soy, can detriment female fertility in humans, so as a lactose-intolerant individual who is often exposed to soy, I wanted to explore this idea more. However, it was soon brought to my attention that flies do not use estrogen in their reproductive systems (an oversight by yours truly), so I had to slightly alter my course of action.
Now, instead of soy, I am testing three drugs known to impact female fertility in one way or another: Fenugreek, Black Cohosh, and Folic Acid. By combining these drugs in a variety of manners, I am hoping to provide insight as to how people should treat these herbal supplements in regards to their fertility, and the possible dangers or benefits that could accompany consuming these supplements separately, or in reaction with each other. Using an assay-- an experiment-- testing female fertility, I will begin to record my first rounds of data. So far, I have had to do a little more math than most (because I am a bit ambitious and decided to test three drugs) and copious amounts food vial preparation.
Long story short: I owe most of the TRIP initiative staff Diet Coke or other compensation for their much appreciated help.
I may not get the results I desire or expect by the end of this study, but what I want most is to acquire an experience that will further equip me for problem solving and solution developing that I can use in science or elsewhere; so far, my time in TRIP has been doing just that. Wish me luck!
So far, the first few weeks of TRIP have been going really great! It is a completely different kind of environment than what I’m used to, but it’s a fantastic challenge that has pushed me to be more creative and thoughtful. The process of learning about the fruit fly life cycle to communicating information through graphical abstracts to hashing out our own experimental designs has been an incredible experience. I am super excited to continue with the independent projects and present my results!
For my project, I wanted to focus on ways we can simulate cancer for the flies. So, after doing some background research, I found information on how our diet affects our chances of getting certain types of cancer in our lifetime. Based on this, I decided to focus on salt (which Americans consume at almost double the recommended daily dosage) and Vitamin C, which is an antioxidant with several known benefits throughout our body.
My plan is to give my flies large doses of both drugs and then expose them to UV radiation. After some flies are exposed to the radiation, I am going to perform the negative geotaxis assay to assess activity and a microbiome assay to assess overall health. I am then going to compare the results for all the fly groups. I am really excited to see what happens to my flies and the overall effect that these copious amounts of drug have on their systems!
After some soul searching, I finally decided upon a topic that would not only pique my interest, but help answer a question I’ve been asking for years.
Do artificial food colorings cause hyperactivity in children?
The subject of my independent experiment is how living in densely populated environments affects fly mood, with a focus on anxiety and social interactions. Displaying anxiety in response to stressful environments is a trait that flies share with humans, so remember: if you’re ever feeling anxious, just know you aren’t alone, because a lot of flies are currently feeling that way as well.
What proved harder was figuring out how much space to give the flies, and how much food I needed to make that space. I used a “standard” vial of flies (60 flies in 19 cubic centimeters) to calculate that the flies’ normal density is about 3 flies per cubic centimeter. This is probably one of the strangest units I’ve ever worked with, but I was able to use this average to make vials that gave the flies twice as much space, standard space, half the space, one third of the space, and one quarter of the space. After they’ve spent several days in these vials, I will test their response to the social space and centrophobism assays.
During the first few weeks of this program, I learned so much about being in a lab and how to manage fruit flies.
Did you know that you could use CO2 to anesthetize flies and sort them?
You can also use ice to knock them out for assays.
Howdy, all! My name is Olivia Bamford, and I’m going to be a senior at Wissahickon High School in the fall. Before I get into the juicy details about how science plays a role in my life, some other things about me are that I’m part of my school’s Gay-Straight Alliance, Debate and Speech team, concert band, and school newspaper (I’m very busy, but it’s okay -- sleep is overrated [it’s not.]). I also do Kenpo karate outside of school and have my second degree black belt!
Anyways, having grown up in a heavily science-oriented family, my exposure to the field has been a constant part of my life, starting with those DIY science kits you can buy at LearningExpress. While my school has fantastic and ever-growing opportunities for students to engage in the STEM environment, it lacks the research component of STEM. So when I heard about a few of my classmates and friends doing TRIP for the past winter session, I was super interested! I thought it sounded awesome, with its emphasis on an independent research project, something I’d never even thought of doing until well into college. Thus, I decided to apply for the summer 19 session of TRIP, blah, blah -- and the rest is history!
Anyways, so far TRIP has already taught and exposed me to SO much (and that’s not even including the newfound train station/schedule navigation skills ;)). I was really nervous for the first day (admittedly, I barely slept the night before because of nerves), but I was pleasantly surprised to find that the environment is a lot less… scary? I guess? New things are, obviously, very daunting, and I tend to overthink my expectations; however, the first two days were AMAZING! It was really cool to take some of the things that I have learned in school (example: using a micro-pipette), and then take them to another level (follow up example: actually reading a micro-pipette and setting it). Additionally, my mom worked with fruit flies when she was younger, so it’s really cool to compare my experience so far with her’s-- it makes for great dinnertime conversation.
Hi everyone! My name is Rachel McCabe and I’m going into my senior year at Friends’ Central School.
My favorite subjects are science and history. I’m also on the Field Hockey and Track teams, and I play the flute in the orchestra. Outside of school, I love to hang out with my friends, watch Netflix (I’ve recently been very into Grey’s Anatomy and Criminal Minds), and bake. I love to experiment and try out new recipes and foods, but I’m gluten free which can make it a little difficult. This summer, when I’m not at TRIP, I will be teaching swim lessons at Swarthmore College. I’ve been doing it for the past two summers, and always had a lot of fun. I wanted to do TRIP because I love science, and I think the program is a good way to experience what a career in research could be like.
Having finished my first week, I’ve already learned so much. It’s kind of crazy to me that the classes are five hours long, as so far they have felt much shorter. The first day, we learned how to make fly food and use micro-pipettes. I also found out that I will be experimenting next week to find out how constant darkness and St John’s Wort (a drug typically used for depression in humans) affect the social interactions of flies. I will be doing this by using the Social Space Assay, which monitors the distance between flies. I predict that constant darkness will cause an increase in the distance between flies, while St John’s Wort will cause the flies to be close together.
In my free time, I love to take on volunteering because it gives me something to do in my free time and teaches me how to adapt to the outside world. I mainly volunteer at the hospital because I enjoy talking with patients and other volunteers. If I am not at the hospital, I am either tutoring kids at my house or at the middle schools. I love to share my knowledge with others. Once I learn about a topic, I like to discuss or share what I learned with others. One time, I spent most of a car ride home from New York continuously talking with my cousin about the heart and recent advances in the science field. My passion for learning and discussing information drives my passion to share it with others. However, I want to learn how to share information formally to the public, which I hope TRIP will teach me. I also swim and play basketball in my free time and if I am not listening to music (Khalid is my favorite) I am either watching TV (The Office and Parks and Rec) or going on walks with my friends which is my favorite!
So far, I have gotten comfortable in the lab, and started working on the first assignment,
which for me involves testing the effects of Holy Basil and UV exposure on locomotion. I enjoyed learning the lab techniques that I will eventually apply to my independent project, such as brushing up on pipettes, and learning how to tell the gender of a fly. I also learned how to use various machines in the lab. One that stands out to me is the UV machine, which administers UV light to flies that are placed inside. I didn’t know this was a thing before Thursday, and it was cool to learn about something completely new to me. After just two lab sessions, I am already seeing my skills expanding, and I cannot wait to see how far they will come before the end of TRIP. I look forward to next week, when we will continue our preliminary experiment, and have our first presentation about our findings, getting us on track for the August presentation of our independent projects.
