Description Billions of years ago, an hours-long Martian sandstorm blew so intensely that sand ripples began to climb upon one another as they moved across the surface. These layers of sediment eventually hardened into the multilayered rocks seen in this image, which was taken by

Before Artemis astronauts land on the Moon’s surface in 2028, NASA will conduct the Artemis III demonstration mission in 2027, allowing teams on Earth and in orbit to practice rendezvous and docking operations between commercial human landing systems and the Orion spacecraft. Dat

Plastic pollution has become a global environmental crisis, with an estimated 11 million tons of plastic entering the oceans each year. As larger plastic debris breaks down into microplastics, these tiny particles are transported throughout marine ecosystems by ocean currents, th

On a summer afternoon in the Sierra Nevada, a mountain pond can look calm and still, reflecting granite peaks and alpine sky. But beneath the surface, these small, shallow waters are anything but stable. In fact, they are among the most thermally variable aquatic ecosystems on Ea

Integration of smartphone-based imaging and artificial intelligence (AI)-driven diagnostics provides an effective strategy for screening for rare ocular malignancies, according to a study published online June 4 in JAMA Ophthalmology.

When temperatures climb, the cardiovascular system works harder to keep the body cool by redirecting blood flow from the core to the surface of the skin to allow for evaporation. High temperatures can cause blood to coagulate and thicken, making the process even harder on the hea
