Graduate student Reese Martin and his doctoral advisor, Ann Tate, assistant professor of biological sciences, used theoretical modeling to identify a potential relationship between genetic pleiotropy and the evolution of immune responses. Read More

Stephen Ferguson, first-author of a new paper with his postdoctoral advisor, Laurence Zwiebel, along with two undergraduates associated with the lab, Isaac Bakis and Nicholas Edwards, confirmed the existence of a specialized soldier caste within an ant species. Read More

In a review of 100 years of research on the sensory systems in whales, Rachel Racicot, research assistant professor of biological sciences, describes advances in the field and key questions that remain. Read More

A new study shows that insect immune and circulatory systems cooperate to fight infection, similar to those in mammals. Read More

Isotope analysis of ancient Peruvian teeth gives anthropologists a clearer image of how cooperating societies function. Read More

Katherine Amidon, a PhD student in the Department of Biological Sciences at Vanderbilt University, has been selected as the 2020 Vanderbilt Prize Student Scholar. Read More

With a new app from a team at Vanderbilt, birdsong researchers can better leverage crowdsourced fieldwork and audio recordings from amateur birders and citizen songbird scientists. Read More

A new cellular biology study reports the first visualization of a unique shape-shifting structure in the human body which plays an important role in the timely delivery of fats and proteins.  Read More

The quokka, a small marsupial native to Australia, is an example of a species vulnerable to extinction in the country’s harsh surroundings. In a new study, researchers at Vanderbilt University demonstrate evidence for the dramatic decline of quokkas over the past century. Read More

In a new study, scientists at Vanderbilt report definitive evidence of a mechanism within ants that is responsible for unlocking aggression. The research—the first to pinpoint this mechanism and its precise role in ant biology—reports a social characteristic which could help account for their evolutionary success. Read More
