Dolphin Communication Theories and a Tribute to Jimmy Carter

Researchers have projected that by the end of the century, days where snow covers the ground will virtually disappear in the United States, except for in very high mountains like the Rockies. This would affect entire ecosystems, disrupting animals and plants that live beneath the snow and increasing flooding and runoff.

Ira talks with Sophie Bushwick, senior news editor at New Scientist, about the latest snow projections and other top science news of the week, including the discovery of an ancient piece of clothing, how blinking can give you a “cognitive break,” and how dolphins could be using their teeth to improve hearing.
