Bye-bye batteries? Power a phone with fabric or a beacon with sound
New piezoelectric systems produce electricity in unusual ways, such as when a certain nylon bends or underwater ceramics vibrate.
- Brain
A taste map in the brain is a scattering of tiny flavor islands
Some senses are highly organized in the brain. Taste is not. And that points to just how important it is.

A soil-based ‘concrete’ could make buildings green, even on Mars
A new soil-based material offers an alternative to concrete for 3-D printing environmentally friendly buildings.

Old clothes soon may be recycled, not trashed
One day, clothes may be recycled almost as much as plastics and glass are now. See how chemists are moving us in that direction.

Star of science and movies, the Arecibo radio telescope is dead
Broken cables led to catastrophic damage of its history-making dish. The U.S. National Science Foundation will now dismantle what remains.

Why Arecibo’s loss is such a big deal for astronomy
Damage to the radio telescope in Puerto Rico has robbed scientists of a special tool for studying everything from asteroids to galaxies.

Here’s how to make flip-flops biodegradable
Innovative flip-flops made from an algae-based plastic decompose in soil or compost. The comfy shoes also avoid use of fossil fuels.

New device tells smiles from frowns — even through a mask
Most facial-recognition software has to see the whole face to work. The new type can reconstruct an entire expression from just viewing your cheeks.

Around the world, birds are in crisis
Human activities around the world are threatening bird species. Numbers of even some of the most common species are starting to fall.
