*The secret to frogs’ superlative jumping lies in their tendons. Researchers at Brown University, filming frogs jumping at 500 frames per second with special X-ray technology, show that the frog’s tendon stretches as it readies its leap and then recoils, much like a spring, when the frog jumps. The finding could explain how other animals are exceptional leapers. Results appear in Biology Letters.*

PROVIDENCE, R.I. [Brown University] — Some species of frogs and many other animals are able to jump far beyond what appear to be their capabilities. The trained contestants in the frog-jumping competition in Calaveras County, Calif., come to mind, but even ordinary frogs can leap several times farther than their physiology would seem to allow.

“Muscles alone couldn’t produce jumps that good,” said Henry Astley, who studies the biomechanics of frog jumping at Brown University. (more…)

All Nine Women in Brown University Computer Science Class Intern at Microsoft

*After spending a summer working in Redmond, the junior class women of Brown University’s computer science department find new confidence.*

REDMOND, Wash. — This summer, all of the junior class women of Brown University’s computer science department found themselves interning at Microsoft.

They can field their own baseball team, with nine women in all — a group small enough to fit around a large lunch table at The Commons, but large enough to make for vibrant conversation. But baseball isn’t what these nine women all have in common – it’s computer science.
