Using data from the DESI Legacy Imaging Surveys, with help from artificial intelligence, an international team of scientists has discovered 70 new gravitational lenses—rare cosmic alignments that act as natural magnifying glasses. The new lenses further expand one of the largest collections of confirmed lenses to date and will allow scientists to study dark matter, galaxy evolution and the structure of the universe.

Scientists finally see how nature moves energy so efficiently

Researchers have captured key steps in a chemical reaction that helps nature transfer energy with remarkable efficiency. Ultrafast X-rays revealed how changes involving electrons and protons are closely linked to the rearrangement of surrounding water molecules. Because similar r
