A breathtaking astronaut photo reveals El Salvador’s Lake Coatepeque—an ancient volcanic crater lake that sometimes mysteriously turns brilliant turquoise. Lake Coatepeque, located just inland from El Salvador’s Pacific coastline, stands out for its vivid blue water that fills part of a volcanic caldera bearing the same name. On February 10, 2026, an astronaut aboard the […]

Scientists have discovered that applying an electric field to certain ceramics can dramatically redirect how heat moves through them. New research from the Department of Energy’s Oak Ridge National Laboratory, carried out with collaborators at The Ohio State University and Amphenol Corporation, is challenging long-held ideas about how heat can be directed through solid materials. […]

Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown. The surface of Earth has a measurable size. Scientists can calculate its total area, and if the planet were expanding, we would see its dimensions steadily increase over time. Because Earth is something we […]

A bright new lunar crater detected in spacecraft images shows that asteroid impacts continue to reshape the Moon’s surface today. The Moon’s familiar surface tells a story of both ancient violence and ongoing change. While its vast dark basins formed during a period of intense bombardment billions of years ago, new impacts continue to reshape […]

Scientists have developed a new blood test that could spot Alzheimer’s earlier by detecting hidden changes in how proteins fold in the bloodstream. Alzheimer’s disease affects an estimated 7.2 million Americans age 65 and older, according to the Alzheimer’s Association. Current diagnostic approaches often focus on measuring the levels of two proteins—amyloid beta (Aβ) and […]
