Piezoelectric materials turn mechanical energy into electrical energy — and vice versa.
The internet has a big environmental footprint. But this new type of tech could help reduce the climate impact of computing.
Some algae glow blue when they experience forces. Held in transparent plastic, they now make devices light up in response to gentle pushes and tugs.
The sun creates energy through nuclear fusion. Now scientists have too. This achievement raises hopes for developing a new type of clean energy.
Better understanding of ice could lead to new deicing materials or even, someday, weather control.
Kinetic energy depends on an object’s motion; potential energy hinges on its position. The relationship between the two sits in a special balance.
How does a parachute work? Do bigger parachutes work better than smaller parachutes? Find out in this science project whether the size of the parachute matters.
The new device, which looks like a pair of plastic pinchers, is the first to be able to pick up individual droplets of liquid.
Tangled polymer chains help hydrogels hold their shape despite being full of water.
