Birds in tiny goggles, exploding batteries, and more

A tiny crack in one of Antarctica's ice sheets has now grown 70 miles long and more than 300 feet wide, and it's causing an iceberg the size of Delaware to break off of the continent. The crack is in one of the Larsen ice sheets, which NASA has been tracking since a large piece broke off in 1995. Larsen C is expected to break away soon, which could have a major impact on the rest of the sheet.
