Lauren RubensteinJohn Kirn, professor of biology, professor and chair of the neuroscience and behavior program, was interviewed on WNPR public radio on June 25 about his research on neurogenesis, or the formation of new neurons, in the brains of zebra finches. "The birds that had managed to preserve their songs the longest had the most new neurons, which was completely counter to our prediction. It suggests that maybe, at least in some cases and in some brain regions, new neurons are being added in order to preserve what's already been learned," Kirn said in the interview, describing the findings of his latest…
Olivia DrakeJohn Kirn, professor of biology, chair and professor of neuroscience and behavior, is the co-author of three recent articles. They include: "Adult neuron addition to the zebra finch song motor pathway correlates with the rate and extent of recovery from botox-induced paralysis of the vocal muscles," published in the Journal of Neuroscience, 31(47): 16958-16968. Yi-Lo Yu ’03, MA ’04 co-authored this paper. "Morphological plasticity in vocal motor neurons following song crystallization in the zebra finch," published in the Journal of Comparative Neurology, Accepted manuscript online on April 2, 2012. DOI: 10.1002/cne.23120. Biology major Kathryn McDonald Ph.D. '09 co-authored this article. And "Adult neurogenesis is associated…
Sonia Sultan, chair and professor of biology, professor of environmental studies, has been elected to the Connecticut Academy of Science and Engineering. Sultan, an evolutionary biologist, joins 39 other Connecticut experts in science, engineering and technology to membership in the Academy this year. Four other Wesleyan faculty are already members of the Academy. Election to the Academy, according to the CASE web site, is based on scientific and engineering distinction achieved through significant contributions in theory or applications, as demonstrated by original published books and papers, patents, the pioneering of new and developing fields and innovative products, outstanding leadership of nationally recognized…
For the roughly one-third of temporal lobe epilepsy patients for whom drugs are not an option, researchers at Wesleyan are paving the way for alternative therapies using stem cells. Faculty members Janice Naegele, Gloster Aaron and Laura Grabel, together with Xu Maisano, Ph.D. ’11, Elizabeth Litvina, B.A. ’10/M.A. ’11, and Stephanie Tagliatela, the lab manager in the Naegele lab, recently published a landmark study in the Journal of Neuroscience on the use of embryonic stem cells to treat temporal lobe epilepsy (TLE). The researchers derived neural “parent cells” in culture from mouse embryonic stem cells, and transplanted them into the…
A word of caution to the caterpillar munching on that delicious, nutritious black cherry tree: watch out for hungry birds. Michael Singer, associate professor of biology, is the lead author of a new study published in The American Naturalist on the effect of a caterpillar’s choice of feeding spot on its chances of becoming bird food. The article found that on balance, nutritious trees, like black cherry, can increase by 90 percent a caterpillar’s risk of being taken by foraging birds. According to the article, this effect is seen because the most nutritious tree species harbor the greatest number of…
David PesciThis issue, 5 Questions talks about the connections between the Moneyball and biology with Fredrick Cohan, professor of biology. Q: Fred, you’ve been talking about how the data mining revolution in baseball, championed by the Michael Lewis book Moneyball and the recent movie of the same name starring Brad Pitt, can change science in general and biology, specifically. Really? A: Absolutely! On the surface, Moneyball is the story of Billy Beane, the general manager of the Oakland A’s, who found a way to lead his poverty-stricken team to success against teams with many times the payroll of Oakland. But Moneyball is…
Michael Weir, director of the Hughes Program in the Life Sciences, professor of biology, received a grant worth $328,200 from the National Institutes of Health on Sept. 19. Weir will use the funds to support a study titled, "Proteomic Analysis of Translation Initiation of Yeast," through August 2011.
"Drug Design from Transition State Analysis" will be the central topic of the 12th annual Molecular Biophysics and Biological Chemistry Retreat Sept. 22. The public is invited to the retreat, which will be held at Wadsworth Mansion in Middletown. Faculty from chemistry, physics and biology will present lectures. (more…)
Eric GershonIn an op-ed for The Los Angeles Times, Frederick Cohan, professor of biology, professor of environmental studies, discusses how his experience as a child watching perhaps the greatest “perfect game” in baseball history – The Los Angeles Dodgers’ Sandy Koufax’s 1-0 victory over the Chicago Cubs in 1965 – provided lessons for the mining of old data for both baseball front offices and biologists such as himself who specialize in studying bacteria. Read the op-ed here.
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…
Professor Laura Grabel has received a $750,000 grant from The State of Connecticut Stem Cell Research Advisory Committee for her study titled "Angiogenesis of Embryonic Stem Cell Derived Hippocampus Transplants." It is her third grant from the Committee since Connecticut began its state-funded human stem cell research program in 2006, and second where she is the principal investigator (P.I); she was co-P.I. on the other. Grabel, professor of biology and Lauren B. Dachs Professor of Science in Society, is also a co-director of Connecticut’s Human Embryonic Core Facility, a research center in Farmington, Conn. that houses some human stem cell…
