While breathalyzers help police crack down on drunk driving, a similar new device is helping a University of Rhode Island graduate student analyze the dietary changes of migrating songbirds.
Just as human breathalyzers measure an individuals blood-alcohol level, David Podlesak says that his bird breathalyzer measures the "carbon signature" of a birds last meal.
"We measure the ratio of the isotopes of carbon 12 to carbon 13, and this carbon signature in their breath can tell us what the bird ate earlier in the day," said the 36-year-old Wakefield resident who is nearing completion of his doctorate.

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.

Research from a leading international expert on the health of the Great Lakes suggests that the growing intensity and scale of pollution from plastics poses serious risks to human health and will continue to have profound consequences on the ecosystem.
