Experiment: Where does a bouncing basketball’s energy go?
Let’s explore whether energy loss to heat could explain why a basketball doesn’t bounce back to its original height.

Scientists Say: Muon
Tracking muons raining down on Earth can reveal new details of pyramids, volcanoes and thunderstorms.

Restoring giant underwater forests, one blade at a time
Giant kelp are at risk due to climate change and human activities. In New Zealand, a community effort is rebuilding these underwater algal forests.

Heat makes water evaporate. Now it appears light can, too
In the lab, shining light on water made it evaporate faster. This never-before-seen effect, if real, might be happening naturally all around us.

A new tool shows tiny changes in the ’24-hour’ length of a day
An underground instrument known as ‘G’ uses laser beams to measure Earth’s rotation — a gauge of day length — with extreme precision.

Bionic plants and electric algae may usher in a greener future
Some can aid the climate by removing pollutants. Others would just avoid dirtying the environment in the first place.

Analyze This: Tropical forests have gotten patchier
Although many of the world's forests have gotten less fragmented since 2000, tropical forests have gotten more chopped up, putting animals at risk.

Adult corals have been frozen and revived for the first time
Living corals could be frozen for safekeeping. Scientists could later revive them to restore reef ecosystems that are withering in warming seas.

AI can now turn blurry thermal vision into crisp images
Even when it’s pitch black, the new imaging system can create clear images while also accurately gauging distances to objects.

Nanobots can now enter brain cells to spy on what they’re doing
Fleets of advanced versions may one day be able to detect disease and then go about surgically treating it — without ever opening the skull.
