According to a new study, the tiny zebrafish may hold the secret to regenerating damaged retinas in humans. Read More

Investigators have discovered how a DNA repair pathway protein shields sites of damage to avoid mutations and maintain genome integrity. Read More

This work was the foundation for an NSF grant to interrogate how the Rif1 protein controls DNA replication. Read More

James Patton and colleagues have demonstrated how colon cancer cells transmit genetic data to other cells. Read More

Prof. Carl Johnson and his team discovered on-and-off interactions between KaiA and KaiC take only seconds but combine to create a 24-hour oscillation of phosphorylation in a test tube. Read More

Bordenstein’s team studied Nasonia parasitic wasps, which are about the size of a sesame seed, and they serve as one of the best models to dissect and characterize the evolution of insect genomes. Read More

How a bacteria hijacked insect fertility remained a mystery for five decades, until Associate Professor of Biological Sciences Seth Bordenstein and his team helped solve it. Read More

Vanderbilt scientists have taken an important step toward understanding the way in which injured cells trigger wound healing, an insight essential for improving treatments of all types of wounds. Read More

Ken Catania stuck his arm into a tank with an electric eel 10 times -- the only way to get accurate measurements of the circuit created by animal, arm and water. Read More
