A new hydrogel uses hot air to create clean drinking water using nothing but energy from sunlight.

A new device gets power from sunlight to extract molecules from the air and convert them into drinking water.

A powder disinfects contaminated water when exposed to sunlight. It could bring clean water to 2 billion people around the world without it.

A solar "mini-refinery" that can turn sunlight and air into carbon-neutral fuels has proven its effectiveness over the course of years, researchers say.

A new way to make rocket fuel on Mars to launch astronauts back to Earth uses three simple ingredients: carbon dioxide, sunlight, and frozen water.

Evidence indicates that COVID-19 transmission is sensitive to changes in UV radiation exposure, but it's too early to say if it changes seasonally.

Why does laundry that dries outdoors in the sunshine smell so nice? Researchers conducted an experiment to find out.

An artificial photosynthesis panel could use sunlight and water to convert carbon dioxide from smokestacks into usable "green methane."

If solar panels could gather sunlight from two sides instead of one, they could generate up to 20% more power, a new formula shows.
