Effects of Acetone on the CrdRS Pathway of H. pylori

Hey everyone!

My name is Yusheng Qin. I’m a rising Junior and a Biology major at the College of William and Mary. For the past year, I’ve been working in Dr. Mark Forsyth’s lab on signal transduction in Helicobacter pylori. H. pylori (HP) is a bacterium that causes many gastric diseases in humans such as gastric ulcers and gastric cancers. In order to thrive in the highly acidic environment in the stomach, HP has evolved complex mechanisms for resistance to environmental changes in the stomach such as pH fluctuations. One way the gastric pathogen achieve this is through the use of two-component signal transduction (TCST) systems. This summer I will be studying one of these TCST systems named CrdRS.

A Study of the Microbial ecology of Storm Water Retention Ponds

Hello! I’m Jasmin Green, a rising Junior, Biology and Environmental Science major. I have been working in the Microbial Ecology lab under Dr. Williamson’s lab for the past year. The lab studies the interactions of microbial communities with each other and with their physical environment, with special focus on viral ecology in soil and freshwater systems.

Developing anti-predator stimuli in Zebrafish

Hello Readers,

My name is John Stella and I am a rising sophomore at the College of William and Mary. This summer I am doing research with Professor Hunt, in the Psychology department, on fear conditioning in Zebrafish. Fear conditioning involves determining whether the zebrafish can learn cues that signal an oncoming fear stimulus and whether it will cause them to react with fear before the actual fear inducing stimulus or in its absence. However, first I need to create appropriate stimuli to provoke fear(adaptive anti-predator) behaviors. To do this I will try to get a video clip of a predator fish striking at the camera that can be screened on the side of a tank during fear training. The video clip will eliminate the inconsistency of using live predators during testing and will hopefully produce more pronounced fear responses than alternative and less lifelike stimuli.
If the video clip is obtained I can then use it to test the level of response from zebrafish to the striking image of a predator. If anti-predator responses are present, I will then test two groups of fish to see if the cue that signals an oncoming fear producing stimuli can be learned by one of the groups and will result in their showing anti-predator responses before the actual fear producing stimuli is shown. In the future the fear provoking stimuli I hope to develop can be used in other fear conditioning research, for example in studying the affect of fetal alcohol syndrome on learning and memory in zebrafish, which Professor Hunt has studied for 25 years in rats.

Geocoding Nepal

Hey everybody! My name is Mike Hathaway and I am a rising junior at the College of William and Mary. I am currently an Economics major, and will likely pursue a Chinese minor. This summer I am going to travel to Kathmandu, Nepal. There I am going to be working with the Nepal branch of Transparency International (TI-Nepal) – an international civil society group that publishes the corruptions perceptions index. They are helping to lead the fight against corruption globally. This fight is crucial to making sure that society can most effectively support its members. I will be leveraging my experience with AidData to help train TI-Nepal staffers in geocoding and data visualization methodology. By doing so, I hope that I can help make sure that development finance is actually going where it is supposed to. [Read more…]

Promoting the Utilization of Geocoded Aid Information at Kathmandu University

Hi everyone! My name is Carleigh Snead, and I am a rising junior and International Relations major at the College of William & Mary. For the past year, I have been interning at AidData, learning the methodology and technical skills behind geospatial data analysis. AidData seeks to improve the transparency of the foreign aid process by both increasing the availability of information about development projects and promoting the use of data visualization tools to glean meaningful information from such large datasets.
