NASA’s James Webb Space Telescope takes us 4.4 billion years into the past with this July 3, 2026 image of a young galaxy cluster, MACS J0553.4-3342. The group is composed of two actively merging subgroups that have approximately the same mass. Each subcluster is anchored by an immensely bright and massive elliptical galaxy, easily identifiable

Credit: Denis Borisov/Getty Researchers are increasingly using autonomous AI agents for data interpretation. The accuracy of this analysis depends on the data sets available to these programs, and a new study documents how easy it is for scammers to “poison” these resources by uploading manipulated data sets that closely resemble the originals but lead to

Mitochondria (green in this false-color transmission electron micrograph) may play a role in the physiological effects of microgravity.Credit: José Calvo/Scientific Photography Library Researchers have found that exposure to microgravity aboard the International Space Station causes mitochondria in human cells and worms to produce fewer proteins. The work also identified a previously unknown molecular pathway that
