WEIRD JOY

This one-gram robot can hop over a stair.

DirectHop uses a tiny motor and three folding legs to make controlled, repeated jumps. The prototype can clear a standard stair and twitch itself upright after a fall.

A sea turtle just nested on the West Coast for the first time on record.

Lifeguards were called to an injured turtle near Seal Beach on 16 September. She was not injured. She was digging a nest — and three days later it happened again near the Huntington Beach Pier. NOAA Fisheries says it is the first recorded natural nesting of any sea turtle species on the U.S. West Coast. Both nests are now fenced, signed and monitored.
