What did you hide from your parents / Sleep is more important than you know / Four people pretending to be on Mars

A new study confirms what every teenager already knew: they're not telling their parents about the sketchy stuff they see online, because they're afraid of the freak out that would follow. Also: just one night of bad sleep can spike the exact brain proteins associated with Alzheimer's disease by 25 to 30 percent — and a week of poor sleep makes it worse. And four volunteers at NASA's Johnson Space Center just hit 200 days inside a 1,700 square foot 3D-printed habitat pretending to be on Mars, with 178 days still to go. Plus a hacked robot lawn mower, a Buddhist robot monk, two Florida alligators, and a bear that wanted a pastry. Hosted on Acast. See acast.com/privacy for more information.
