#ScientistsofDuquesne interview with biology student, Laura Reynolds. Interview conducted by Jacob Cavender and Claire Neiberg, photo provided by Reynolds | Laura Reynolds is a sophomore biology major and is working with behavior tests focusing on the difference between male and female responses to pain. The lab she has been working with for about four months is using rats to study these behavior patterns. First, they perform surgery to put ligatures on the sciatic nerve by their back paw. Then another incision is made on the other leg without the ligature put in place to keep a comparative control. The rats are then monitored for the behavioral portion of the study. Then they are given a type of pain killer called a nano emulsion which targets the area of pain directly. The behavioral studies are then repeated to look for differences in the rats without chronic pain. Right now, Reynolds is working with tissue slides from the sciatic nerves and doing tests with antibodies but will soon be more involved with the behavioral studies as well. She finds the research to be very engaging but can be difficult, stating, “I want to keep doing research as a career… research is definitely something I want to continue with." Reynolds has not decided yet whether she would like to continue with pain research or move to more genetics and cancer-based research.

Come to a D.U. Quark meeting on: Monday, February 18th at 4:30pm in Room 640 of College Hall or Thursday, February 21st at 6:00pm in the Quark office (Mellon B4A) Hope to see you there!

#ScientistsofDuquesne interview with Forensic Science and Law student, Amelia Bullard. Interview conducted by Jacob Cavender, written by Claire Neiberg, and photo provided by Bullard | Amelia Bullard is a fourth-year forensics major working in the biology department under the instruction of Dr. Jan Janecka. Since last spring, she has been doing research on the white bellied pangolin—an animal that resides in South Eastern Asia and Africa. The basis of her research is to develop a multiplex PCR which allows her to see the exact DNA sequence of each individual pangolin so she can differentiate them from one another. By doing that, researchers can go into their habitat, track and conserve them better. The pangolins have become the world’s most trafficked mammal due to the Chinese believing they have medicinal properties. Bullard obtains blood samples from the Pittsburgh Zoo then collects blood samples to extract the DNA. She then amplifies that DNA to genotype it. Her favorite part about her research is going to the zoo, because she actually gets to interact with the pangolins. However, her research has its challenges as it is time consuming and certain primers used do not bind well to the DNA. While her main drive is to complete her independent forensic research to graduate, Bullard also wants to educate people about animal conservation and the environment.

Our first meeting will be this Monday, January 28th at 4:30pm in the Quark office (Mellon B4 A in the basement). We will be discussing upcoming events and ideas. Please make an effort to attend if you can!

Send us your final science papers and we may put them in the @theduquark
