Birdsong performed by males has a direct role in evolution—its main functions are to attract mates and defend territory from rival males. But female birds sing, too, and their abilities may reflect generations of cooperation in breeding and parenting. “Birdsong … sits at the intersection of genetics, learning, culture and social interaction,” says Associate Professor Nicole Creanza, who has just published a paper about female birdsong with postdoctoral scholar Kate Snyder. “By studying how cooperation and territorial behavior influence communication in birds, we gain insight into how social complexity shapes evolution more generally,” Snyder adds. Their research was funded through a Vanderbilt Scaling Success Grant. Read More

Ointments like Neosporin contain the antibiotic neomycin, which works great to kill bacteria on the outside of the body when you scrape your knee or have a hangnail. But inside the body, neomycin does more harm than good—kidney and neurological damage and deafness. Research Assistant Professor Bhawik Jain and colleagues in his lab have figured out why that is, and how to stop it. This could make neomycin another tool in the fight against antibiotic-resistant bacteria. Read More

A new study by Vanderbilt investigators uncovered a previously unknown biological mechanism: how tissues detect and respond to damage in basement membranes, the thin layers of extracellular matrix that surround and support nearly every organ in the body. The research, published in Developmental Cell, is the first to show how local cells sense and respond to changes in basement membrane stiffness caused by damage—and how they activate a previously unknown set of “matrix mender” cells to repair the tissue.

The highly selective Beckman Scholars Program is celebrating 15 years of partnership with the College of Arts and Science. Over the years, the Arnold and Mabel Beckman Foundation has provided more than $543,000 in support of 23 undergraduate Beckman Scholars at Vanderbilt who engage in unique, hands-on, mentored research.

According to a new study published by biological science researchers at Vanderbilt, the answer to eating (or fasting) windows lies in the circadian rhythms of the body’s biological clock.  Read More
