Researchers at Yale have developed a new technology that could make energy from the low-temperature wasted heat produced by industrial sources and power plants, tapping into a widely available — and mostly unused — resource. (more…)

Save Threatened Species by Giving Them Treated Cotton for Nests
When University of Utah biologists set out cotton balls treated with a mild pesticide, wild finches in the Galapagos Islands used the cotton to help build their nests, killing parasitic fly maggots to protect baby birds.

“We are trying to help birds help themselves,” says biology professor Dale Clayton, senior author of a study outlining the new technique. The findings were published online May 5, 2014, in the journal Current Biology. (more…)
