Nov. 28, 2016—A laboratory study of four animal species and their microbiota finds that each species hosts a unique community of microbes that can significantly improve its health and fitness.
Oct. 27, 2016—A team of Vanderbilt scientists have genetically modified luciferase, the enzyme that produces bioluminescence, so that it acts as an optical sensor that records activity in brain cells.
Oct. 11, 2016—DNA related to black widow spider toxin been discovered in a phage that infects the bacterial parasite Wolbachia. It is the first time animal-like DNA has been found in a bacterial virus.
Aug. 2, 2016—There is new evidence that the "mother’s curse" – the possibility that moms may transmit genes to their children that harm their sons but not their daughters – holds true in animals.
Jun. 21, 2016—Sidney Fleischer, a renowned molecular biologist famous internationally for his work on calcium and the discovery of the ryanodine receptor, was remembered as a “true giant” in his field who worked along with his wife to advance the field of cell signaling. He died May 27 at the age of 86.
Jun. 6, 2016—Vanderbilt biologist Kenneth Catania has accidentally discovered that electric eels can make leaping attacks that dramatically increase the strength of the electric shocks they deliver. In doing so, Catania has confirmed a 200-year-old observation by famous 19th-century explorer and naturalist Alexander von Humboldt.
Jun. 2, 2016—High school students performing advanced research at Vanderbilt have the opportunity to share their findings with the scientific community through a journal of their own.
