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 ...

Efficiently cooling satellite components in space

Space is a vacuum. Heat therefore cannot be transferred to the surroundings by thermal conduction. This poses a problem for any type of space-capable electronics, which can quickly overheat under these conditions. The only ...

Engineering

Underground acoustic signals reveal hidden tunnels

For decades, engineers have searched for underground tunnels by sending signals from the surface downward—an approach that can miss what lies below. By reversing that approach, researchers at the Department of Energy's (DOE) ...
