New Weapon to Fight Dangerous Infections
Tufts researchers find drugs already approved for other uses in people help frogs survive deadly E. coli by changing their cells' electrical charge. This paper was written by Jean-Francois Pare, Ph.D., and Dr. Michael Levin joined by Christopher J. Martyniuk of the Center for Environmental and Human Toxicology and Department of Physiological Sciences, University of Florida Genetics Institute, College of Veterinary Medicine, University of Florida, Gainesville.

New research led by Tufts University shows that the invasive European paper wasp, Polistes dominulus, plays a role in facilitating sour rot disease in the absence of other insects.

USA Science and Engineering Festival 2016
This year, the Tufts BUGS (Biology Union of Graduate Students) were lucky enough to participate in the USA Science and Engineering Festival which is held in Washington, D.C. The mission of the USA Science and Engineering Festival is "to stimulate and sustain the interest of our nation's youth in science, technology, engineering and math (STEM) by producing and presenting the most compelling, exciting, and educational Festival in the world." With over 3,000 interactive activities, 50 stage shows, and 350,000+ visitors over the course of the weekend, I'd say the Festival has achieved its mission! Being able to take action and participate in such an admirable mission was truly a transformative experience.

Spear-headed by Emily Pitcarin and Kyle Jewhurst, BUGS started planning for the event about a year ago. In one short year, we formed committees to come up with–and solidify–three interactive activities all with the same theme: communication. In total, 12 graduate students attended the event: Rachael Bonoan, Rory Fuller, Brenna Gormally, Kyle Jewhurst, Varandt Khodaverdian, Elizabeth Landis, Marcus Lehr, Clare Parker, Kaylinnette Pinet, Emily Pitcairn, Taylor Sands-Marcinkowski, and Ishtiaque Quasem.

Jennifer Mortensen, Reed Lab Group, successfully defended her Ph.D. thesis, "Multifaceted characterization of extinction risk in the endangered, cooperatively breeding White-breasted Thrasher (Ramphocinclus brachyurus)".

Jennifer Nguyen, Freudenreich Lab, successfully defended her Ph.D. thesis, "Roles of the Srs2 helicase and the Ctf18 clamp loader in replication of structure-forming CAG repeats in S. cerevisiae".

Biology seniors, Jennifer Hammelman and Maya Emmons-Bell, are featured in an article, "Research That's Fit to Print". The article is also in rotation on the A&S homepage.

Daniel Lobo, postdoctoral fellow in the Levin Lab, accepted a position as Assistant Professor at the University of Maryland, Baltimore County to start his own lab.

Rachael Bonoan
, Ph.D. candidate in the Starks lab, attended two conferences: Protecting Pollinators in Ornamental Landscapes in Hendersonville, NC and Social Insects in the North-East Regions 5 at Boston University. Rachael was also awarded the Tufts Institute of the Environment Travel Grant, and Nooria Al-Wathiqui and Rachael published a paper in Physiological Entomology (Bonoan RE, Al-Wathiqui N, Lewis S. 2015. Linking larval nutrition to adult reproductive traits in the European corn borer Ostrinia nubilalis. Physiological Entomology 40: 309-316).

Crista Wadsworth, Dopman Laboratory, successfully defended her Ph.D. thesis, "The Mechanisms and Consequences of Evolution in Phenology". Congratulations Crista!

Charles van Rees, Ph.D. candidate in the Michael Reed Lab, was featured on 2 local Hawaiian TV shows that featured his research. They can be seen here.

Simran Kaushal, Ph.D. candidate in the Freudenreich Laboratory, was awarded second place in the Tufts Ignite competition. Every Fall students from AS&E have the opportunity to present their research in a five-minute presentation format to an audience and judges. Congratulations Sim!
