[youtube width="640" height="420"]http://www.youtube.com/watch?v=49QKAlwdq8s[/youtube] Q: Mary, what is your class year, and what are you majoring in? A: I'm a junior, and I'm double-majoring in neuroscience and behavior and English. Q: You’re currently working in the lab of Jan Naegele, professor of neuroscience and behavior, professor of biology. Can you tell us a bit about your research in the Naegele Lab? A: The Naegele Lab studies temporal lobe epilepsy (TLE), which involves instances of elevated electrical activity in the brain called seizures. In cases where medication does not alleviate seizures, TLE patients experience cell death and damage in the dentate gyrus,…
There's something fishy about one of Connecticut's minnows, and the topic hooked researchers in the Department of Biology. During the last ice age, Connecticut was covered by layers of snow and ice, forcing organisms to seek refuge elsewhere. After the glaciers retreated, recolonization of the fauna and flora resulted in the diversity of native species that inhabit the state today. "But where did they come from? How did they come back to the Northeast to give us all the organisms we see today?" asks biology graduate student Michelle Tipton. "These questions are of particular interest to the ichthyologists at Wesleyan with…
This semester, 18 earth and environmental sciences majors explored dwarf mangrove forests, studied landslide susceptibility in a rainforest, examined if cave rocks record bat inhabitation, and analyzed the chemistry of coastal seagrass – all in Puerto Rico. The students, who are enrolled in the E&ES 398 course Senior Seminar, developed observational, interpretative and research skills through their island studies. The seniors traveled to Puerto Rico in January for fieldwork, and spent the past few months analyzing their findings. They presented their Senior Seminar Presentations on April 19 and 21 as part of the Stearns (more…)
By synthesizing the antimatter particle antihydrogen, physicists will have the ability to create a more accurate picture and explanation of the universe. "Would antimatter fall down -- or fall up?," asks physics major Guy Geyer '13. "If we could trap antihydrogen for a longer length of time, we could test the gravitational effects of the particle. This would certainly be what scientists aim to do in the end." Geyer, who studies antihydrogen at Wesleyan, received honorable mention for the 2011-12 Barry Goldwater Scholarship. He competed with 1,095 mathematics, science, and engineering students nationwide for the award. Geyer began his antihydrogen…

Marshall Johnson’s research is out of this world. For the past two years, the senior astronomy major used the Van Vleck Observatory’s 24-inch Perkin Telescope to study the transits of “exoplanets,” or planets outside our solar system, that orbit another star. His study, titled “First Results from the Wesleyan Transiting Exoplanet Program,” explains a refined orbital period of a newly-discovered planet named WASP-33b (Wide Angle Search for Planets). Ultimately, Johnson may prove that he’s discovered another planet, WASP-33c. “Here in Connecticut, with clouds and haze, we don’t have the best observing conditions, but I was still able to obtain high-quality…
Eric GershonSarah Kopac, a Ph.D student in Professor of Biology Fred Cohan’s lab, has won a $20,000 NASA grant for research on ecological aspects of bacterial evolution in Death Valley National Park. The grant, announced Jan. 11 by the Connecticut Space Grant College Consortium, will support Kopac’s study of Bacillus subtilis, a bacterium commonly found in soils that can endure extreme conditions, such as high heat levels. Kopac, a third-year Ph.D candidate, is focused on identifying bacterial species that evolved within a gradient of salty soils – part of a broader effort to understand how ecological factors influence the spawning of…

On July 11, Craig Malamut ’12 photographed a pacific solar eclipse 2,500 miles west of South America. As a Keck Northeast Astronomy Consortium Summer Fellow, summer exchange student, Malamut had the opportunity to travel to Easter Island with a group from Williams College. The last time an eclipse occurred over the island was in 591 A.D. The expedition was led by Jay Pasachoff, the Field Memorial Professor of Astronomy at Williams College and chair of the International Astronomical Union's Working Group on Eclipses. This was Pasachoff's 51st solar eclipse study; it was Malamut’s first. “Before getting this position, I was…
In some models of origins of life, hot springs are considered to be one of the first environments inhabited by life. During the 2010-11 academic year, biology BA/MA student Jane Wiedenbeck '10 will use a NASA-funded Graduate Fellowship to study the evolution of certain microorganisms to discern how life may have originated and evolved under extreme conditions. Wiedenbeck, who applied for the fellowship during the fall 2009 semester, received a $20,000 award from the Connecticut Space Grant College Consortium. The Consortium is a member of the NASA-funded national Space Grant College and Fellowship Program, and serves to promote and support…
