Swim

The new light-guided swimmer uses one layer of living muscle to propel and steer itself through a Petri-dish maze. The thin design could one day help soft robots reach underwater spots rigid machines can't enter.

Scientists have created a robotic bird that swims, dives, and rockets out of water to fly, all without propellers, legs, or folding tricks. Just clever engineering solving a problem nature already does gracefully.

Form has updated its Smart Swim 2 goggles, which track your performance and heart rate in the water, and show you those stats in a heads-up display. The latest version is now more durable, thanks to the inclusion of damage-resistant Gorilla Glass.
