Piezoelectric materials produce an electric voltage when they are bent or squished. This can let us harvest electricity from movement.
The experiment revealed how long it takes light to cross a hydrogen molecule: just a couple hundred zeptoseconds.
Some types of face masks muffle speech more than others — something that teachers should take into account.
This invention grabs water from the air at night. All it needs is the sun’s warmth the next day to release that moisture to growing plants.
Gravity is an attraction between objects with mass. The more massive the object, the more gravity it’s got.
New piezoelectric systems produce electricity in unusual ways, such as when a certain nylon bends or underwater ceramics vibrate.
A new soil-based material offers an alternative to concrete for 3-D printing environmentally friendly buildings.
A fluorescent polymer duo boosts the efficiency of solar cells. One day this material may coat your jacket, hat or backpack to provide power on the go.
The tip of a spiraling football follows the ball’s path. If you know a thing or two about gyroscopes, this is not what you’d expect.
