Research is being done on elephant seals in California. They spend seven months of the year just eating fish and squid out at sea. When they're doing these short power naps during this time, they're only sleeping two hours a day. It would be really dangerous if a shark came along at that point. So that's why they have to do it so low down.

00:47 A focus on women’s health
Nature’s Kerri Smith and Heidi Ledford join us to discuss two Features published in Nature looking at topics surrounding women’s health.

Stars have a finite lifespan, and for many their fate is to expand as they reach the end of their lives. It’s long been speculated that these growing stars will consume any planets in their way, but this process has never been seen directly. Now though, a chance observation led to a team catching a dying star in the act of eating a Jupiter-like planet in the distant Milky Way.
We discuss some highlights from the Nature Briefing. This time, a clearer image of the supermassive black hole M87*, and how elephant seals catch some shut-eye while diving.
