It is peak mosquito season, and while some lucky outdoor venturers seem unperturbed by the tiny insects, others appear to be relentlessly assaulted. Laurence Zwiebel, Cornelius Vanderbilt Professor of Biological Sciences, explains the most common culprits. Read More

Vanderbilt phylogeneticists examined the reasons why large-scale tree-of-life studies are producing contradictory results and have proposed a suite of novel techniques to resolve the contradictions. Read More

Vanderbilt researchers have figured out how to set the mosquito's heart racing, helping them understand how the insect's immune system works and the methods that mosquito-borne parasites like those that cause malaria and yellow fever employ to circumvent it. Read More

According to Seth Bordenstein, assistant professor of biological sciences, studying Wolbachia has yielded some surprising new insights on microbial evolution that could help us understand, treat and prevent certain infectious diseases. "It's what gets me up every day and keeps me excited about doing this work." Read More

(iStock) The circadian clocks that control and influence dozens of basic biological processes have an unexpected “snooze button” that helps cells adapt to changes in their environment. A study by Vanderbilt University researchers published online Feb. 17 by the journal Nature provides compelling new evidence that at least some species… Read More

Neuroscientist Kenneth Catania has resolved a long-standing scientific debate by showing that the common mole can smell in stereo. Read More

Kenneth Catania, Stevenson Professor of Biological Sciences at Vanderbilt University, is one of 18 scientists who have been honored by the National Academy of Sciences for their outstanding scientific achievements in a wide range of fields spanning the physical, biological and social sciences.

Vanderbilt biologists have discovered that mosquitoes possess a previously unknown mechanism for destroying pathogens which takes advantage of the peculiarities of the insect’s circulatory system to increase its effectiveness. Read More

Researchers have discovered that alligators and crocodiles possess one of the most acute senses of touch in the animal kingdom. Read More

After more than a decade spent successfully decoding the malaria mosquito’s sense of smell, the Zwiebel Lab has added ant olfaction to its research repertoire and has just received a major grant to pursue this new avenue for the next four years. Read More
