A new study in Science reveals that the fundamental wiring of the olfactory system in mice sets up shortly after birth and then remains stable but adaptable. The research highlights how important early development can be throughout life and provides insights that may be important in devising regenerative medical therapies in the nervous system.

PROVIDENCE, R.I. [Brown University] — To accommodate a lifetime of scents and aromas, mammals have hundreds of genes that each produce a different odorant receptor. The complex and diverse olfactory system they build remains adaptable, but a new study in the journal Science shows that the system’s flexibility, or plasticity, has its limits. Working in mice, Brown University scientists found that the fundamental neural wiring map between the nose and the brain becomes established in a critical period of early development and then regenerates the same map thereafter.

Discovery of new fossils reveals key link in evolution of hind limbs

Researchers have discovered well-preserved pelves and a partial pelvic fin from Tiktaalik roseae, a 375 million-year-old transitional species between fish and the first legged animals, which reveal that the evolution of hind legs actually began as enhanced hind fins. This challenges existing theory that large, mobile hind appendages were developed only after vertebrates transitioned to land.

The scientists describe the fossils in the Proceedings of the National Academy of Sciences, online on Jan. 13. The piece marks the inaugural article for Prof. Neil Shubin, Robert R. Bensley Distinguished Service Professor of Organismal Biology and Anatomy, as a member of the National Academy of Sciences. (more…)

UD joins research team teaching robots to respond in disaster emergencies

How do you teach a robot to get into vehicle and drive it? Three University of Delaware professors plan to figure it out by the end of next year.

Christopher Rasmussen, Ioannis Poulakakis and Herbert Tanner are part of a team competing in a new U.S. Defense Advanced Research Projects Agency (DARPA) Challenge. The team, with members from 10 schools, led by Drexel University, is one of several groups worldwide working to advance robotics technology for disaster relief. (more…)

The Original Twitter? Tiny Electronic Tags Monitor Birds’ Social Networks

If two birds meet deep in the forest, does anybody hear? Until now, nobody did, unless an intrepid biologist was hiding underneath a bush and watching their behavior, or the birds happened to meet near a research monitoring station. But an electronic tag designed at the University of Washington can for the first time see when birds meet in the wild.

A new study led by a biologist at Scotland’s University of St. Andrews used the UW tags to see whether crows might learn to use tools from one another. The findings, published last week in Current Biology, supported the theory by showing an unexpected amount of social mobility, with the crows often spending time near birds outside their immediate family.

REDMOND, Wash. — A team of students from Arizona State University aims to use Microsoft technology to get uneaten meals from restaurants and catered events to nearby families who would otherwise go hungry.

Team FlashFood with its solution, FlashFood, was the winning team in the prestigious software design category at Microsoft’s U.S. Imagine Cup finals on Monday. The team will advance to compete in the Imagine Cup 2012 Worldwide finals in Sydney, Australia July 6-10. (more…)
