Taking the stairs could protect your heart and help you live longer

New research from the University of East Anglia and the Norfolk and Norwich University Hospital suggests that something as simple as choosing the stairs could contribute to a longer life. The large study found that people who regularly climbed stairs had a substantially lower risk of dying from cardiovascular disease.…

A stress hormone may help the brain repair itself

When laboratory mice experience brain damage, e.g., from an injection, Jan Deussing repeatedly notices the same response. A particular group of cells appears and becomes active around the damaged area. Although Deussing, a research group leader and experienced neurobiologist, had observed the phenomenon many times, he did not know exactly…

The findings were published August 12, 2026, in Neurology, the medical journal of the American Academy of Neurology. Researchers emphasized that the results show an association and do not…

Paleontology rocked by organic molecules found in 66-million-year-old dinosaur bones

For decades, scientists generally assumed that fossilization destroyed the original organic molecules once present in bones, teeth, and other tissues. Under that view, proteins and other biological materials were not expected to survive for tens of millions of years. New research led by the University of Liverpool now provides strong…

The Atlantic Ocean can handle more warming than expected — with one big catch

For years, climate scientists have warned that the Atlantic Meridional Overturning Circulation (AMOC) could eventually shut down if global temperatures rise too far. New findings from researchers at Utrecht University suggest that temperature alone does not determine the fate of this major ocean circulation system. The speed at which the…

Neptune’s tiny moons may be the wreckage of shattered ancient worlds

In 1989, Voyager 2 discovered six previously unknown moons around Neptune. Five of them are tiny satellites that travel just beyond the planet’s main rings. Their small size and distant location have made them extremely difficult to investigate from Earth. Now, NASA’s James Webb Space Telescope (JWST) has given scientists…

A massive new cosmic map is revealing black holes, rare stars, and hidden gas

The Sloan Digital Sky Survey V has taken a major step toward mapping the sky on a truly global scale with Data Release 20. Known as DR20, the release includes the first optical (BOSS) SDSS-V spectra collected from the Southern Hemisphere, greatly expanding the survey beyond the groundwork established in…
