Dinosaur-killing space rock may have originated at the edge of the solar system

A new study suggests that the dinosaur-killing object was not an asteroid from between Jupiter and Mars, as is often hypothesized. Instead, the study authors argue, the impactor was a piece of a comet from the Oort cloud, a mass of icy bodies that surrounds the outer edges of the solar system.

'Flatliners' still have heartbeats left. But death comes within 5 minutes.

New research finds that it's fairly common for the to restart — usually just for a beat or two — after a person initially flatlines. No one in the study, which took place in intensive care units (ICUs) in three countries, survived or even regained consciousness. The longest gap between someone's heart stopping and restarting again was 4 minutes and 20 seconds. That's an important number, according to study leader...…Live Science is supported by its audience.
