For the birds: Parakeet co-designs its own perch

Shiso, a ring-necked parakeet, can't speak English, but she knows how to make her preferences known. She has screaming fights with the dogs and cats in her household, snorts for attention and food, and perches on her human ...

Elephant-inspired cement tiles cool buildings without electricity

Inspired by the cracked, water-trapping skin of elephants, Penn researchers have developed a low-cost cement tile that cools buildings by capturing and slowly evaporating water—turning a structural flaw into a climate solution.

Mechanical engineers develop buttons that rise with light

No wires. No actuators. Shine light on the metal surface, and it rises like a button. KAIST researchers have developed a metal structure that changes shape using light, without any light-absorbing coating. This technology ...

AI and physics draw a blueprint for better hydrogen storage materials

Hydrogen can become a clever way to store renewable energy and power fuel cells—but this introduces the problem of what can store this hydrogen, in turn. Metal hydrides—solids that absorb hydrogen into their crystal structures—are ...
