November 2013

John Baker Makes a Sustainable Point at Science Café Woo


Dr. John Baker elaborated upon the notion of sustainability (“Sustainability: It Means More than “Tit for Tat”) in November’s session of Science Café Woo, a monthly forum for active researchers in the sciences to present their work to the community. John sparked a quite lively discussion, as recounted in the blog of embedded research librarian Sally Gore of UMass Medical School’s Lamar Soutter Library.

Science Café Woo, by the way was cofounded with her fellow researcher by one of our own Clark Biology graduates, Kelly Hallstrom, now a doctoral candidate working on Salmonella pathogenesis at U Mass Med. Also by the way, December’s invited speaker at Science Café Woo will be Kelly’s mentor from her days at Clark, Dr. David Hibbett .

Research News

Summer 2010

This summer, several Biology faculty and graduate students participated in an on-campus workshop to learn effective ways to communicate their research interests and findings to members of the media and the general public (Read more).


A new paper published in BMC Evolutionary Biology

Sohini Ghoshroy, Manfred Binder, Aurelien Tartar and Deb Robertson have a new paper published in BMC Evolutionary Biology titled “Molecular evolution of glutamine synthetase II: Phylogenetic evidence of a non-endosymbiotic gene transfer event early in plant evolution" . In this paper, they examined the evolutionary relationship of glutamine synthetase from eubacterial and eukaryotic lineages and present robust phylogenetic evidence that the glutamine synthetase gene was transferred from gamma-Proteobacteria (Eubacteria) to the green algae early in plant evolution. Although horizontal gene transfer events (the exchange of genes between non-related organisms) are common in prokaryotes (e.g., bacteria) they were thought be a rare in eukaryotes. Genome sequencing and phylogenetic analyses, such as the current paper, have begun to reshape our understanding of the frequency of horizontal gene transfers in eukaryotes, which appear more common than previously thought.
