Imagine a "DNA photocopier" small enough to hold in your hand that could identify the bacteria or virus causing an infection even before the symptoms appear.
Ring molecules called cyclic depsipeptides play an important role in living organisms. Microbes make them as part of their chemical arsenal for attacking competitors and they have proven effective as antibiotics, anti-retrovirals ...
Each animal species hosts its own, unique community of microbes that can significantly improve its health and fitness.
"Mood ring materials" could play an important role in minimizing and mitigating damage to the nation's failing infrastructure.
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.
A tiny virus that may sting like a black widow spider. That is one of the surprise discoveries made by a pair of Vanderbilt biologists when they sequenced the genome of a virus that attacks Wolbachia, a bacterial parasite ...
A new scientific study puts the final nail in the coffin of a long-standing theory to explain human's remarkable cognitive abilities: that human evolution involved the selective expansion of the brain's prefrontal cortex.
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.
Newly discovered fossil evidence from Namibia strengthens the proposition that the world's first mass extinction was caused by "ecosystem engineers" - newly evolved biological organisms that altered the environment so radically ...
