When multiple specialists can’t solve the mystery of a toddler’s persistent rashes, grandma offhandedly offers a clue.

Overall, 2017 is likely to be either the second or t ...read more

Now, a new fabric could end that war and save energy at the same time. The textile, described Friday in the journal Science Advances, offers wearers dual heating and cooling, allowing individuals to control their perso ...read more
Tending to a nursing newborn is hard enough, but sea lion moms have an extra challenge. To consume enough calories for themselves and their pups, they have to repeatedly leave their babies behind and swim out to sea to hunt. Each time the mothers return, they have to find their pups again. Australian sea lion moms use a pup’s smell and the sound of its calls to recognize it. They also use sight—which scientists learned by creating fake, stuffed sea ...read more

In all the early chaos, a thousand Plutos may have formed in the distant part of the solar system where Neptune orbits today, including a nascent Ceres. Then the shifting gas giants scattered those bodies everywhere. “In the great rearrangement of the solar system, Pluto went outward, Ceres came inward,” says planetary scientist and New Horizons co-investigator William McKinnon. He proposed Ceres’ migration in 2008 — the first hint of a potential sibling relationship betw ...read more
