"3D battery" design twists together for split-second charging

Most batteries are made up of a cathode on one side and an anode on the other, with a nonconducting separator between them. Now, engineers at Cornell University have developed an unusual new structure that intertwines the components together in a swirling shape, which they say lets the device recharge in a matter of seconds…

Relieving constipation by shining light where the Sun don't shine

The field of optogenetics is all about using light to stimulate cells in the body, and so far it’s been used to modify pain responses in mice, reset the biological clock, and restore regular heartbeats as a gentle alternative to defibrillation. Now, researchers from Flinders University have used the technique to shine a light where the Sun don’t shine, stimulating nerves in the gut to relieve chronic constipation…

3D-printed hydrogel humanoid goes for an underwater walk

After decades of being seen as rigid, metallic creations, robots are starting to soften up. Spongey materials like hydrogels could make for robots that are more flexible, safer to be around and simpler to build and use than their harder counterparts. Now researchers at Rutgers University have developed a smart gel that can be 3D printed into a variety of shapes, and electrically-activated to make it “walk” underwater, grab and move objects…
