Snakes weren't always legless; they evolved the loss of limbs over 100 million years ago and new research from genetics explains why snakes have held on to this limb circuitry through the ages:

"There have been many millions of snake generations since they evolved a legless body, and we would generally expect the DNA associated with limb development to fade away or mutate to do another job, but that doesn't seem to have happened," he said. "Naturally, we wanted to know why snakes had retained DNA that they don't appear to need."

In their experiments, Menke and postdoctoral...

When thieving weeds attack

An international group of scientists that includes assistant professor of genetics Dave Nelson has discovered how parasitic plants, which steal their nutrients from another living plant, evolved the ability to detect and attack their hosts. Their findings were  published recently in the journal Science:

As plant roots grow, they release hormones called strigolactones into the soil. This is a signal that normally helps fungi form a beneficial connection to the plant, in which they each trade nutrients. But the seeds of parasitic plants also possess the ability to sense strigolactones...

Congratulations to Bob Schmitz, assistant professor of genetics, who was recently named a Pew scholar in the biomedical sciences by the Pew Charitable Trusts.

Schmitz, an assistant professor of genetics in UGA's Franklin College of Arts and Sciences, joins the ranks of more than 600 outstanding scientists who have been selected as Pew scholars in the 30 years since the program's inception and whose careers have been dedicated to bold scientific discoveries.

...

Schmitz's research focuses on epigenetics. His laboratory is particularly interested in exploring a...

Metabolomics is the study of chemical processes involving metabolites, and specifically, the system of unique chemical fingerprints that specific cellular processes leave behind. The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, so it is easy to see how this complex is intertwined into many new frontiers of research in human health. 

Arthur S. Edison, one of the leading experts on nuclear magnetic resonance spectroscopy and metabolomics is joining the faculty at UGA as its newest Georgia Research Alliance Eminent Scholar:...

Nice article on the excellent work of UGA students beyond the classroom as part of the Roosevelt Institute, learning as they influence broader public policies:

The Roosevelt Institute Campus Network, founded in 2004, is a national organization that strives to uphold the values cast into the public discourse by Franklin, Eleanor and Theodore Roosevelt and to promote the next generation of leaders through progressive policy. In 2006, Rhodes Scholar Deep Shah (international affairs and genetics) and Gabriel Allen co-founded the UGA chapter of the student-run think tank that...
