This week in science news: Researchers from the National Museum of Natural Sciences in Madrid, Spain, digitally reconstructed the ribcages of four prehistoric Homo sapiens and theorize that climate influences ribcage evolution. A century after it was predicted, physicists have reported the first observation of the transverse Thompson effect, which causes volumetric heating or cooling when an electric current and a temperature gradient flow in the same direction through a conductor. And researchers found neotropical bats in Mexico far beyond their known range.
