Galaxies can create many of the same stellar stream distortions that astronomers have looked to as possible signs of dark matter. Astronomers have long hoped that gaps, bends, and other distortions in long bands of stars around the Milky Way could reveal the hidden influence of dark matter. But new simulations suggest many of those […]
Galaxies May Be Mimicking the Dark Matter Signals Astronomers Have Been Hunting
Galaxies can create many of the same stellar stream distortions that astronomers have looked to as possible signs of dark matter. Astronomers have long hoped that gaps, bends, and other distortions in long bands of stars around the Milky Way could reveal the hidden influence of dark matter. But new simulations suggest many of those […]
New AI Detects Hidden Warning Signs of Solar Eruptions Hours Before They Emerge
AI detected faint signs of emerging solar active regions about nine hours before they became visible on average. Before a sunspot darkens the Sun’s visible surface, the magnetic activity that creates it is already developing out of sight. Those early changes are faint, but researchers say artificial intelligence can now recognize them hours before a […]
“Zombie” Cells Rewire Their Metabolism To Fuel Inflammation As We Age
A study found a new mitochondrial pathway in senescent cells that alters how DNA is stored, exposing genes linked to inflammation. Inflammation is essential when the body needs to fight an infection or repair an injury. But the same protective response can become harmful when it persists, and with age, the body accumulates senescent cells […]

Scientists Discover an Unexpected Mental Health Benefit of Ozempic
A blockbuster drug that transformed diabetes and weight loss care may hold an unexpected benefit for people with bipolar disorder. Researchers at Griffith University found that people with bipolar disorder were less likely to require psychiatric hospitalization while taking semaglutide, the active ingredient in Ozempic and Wegovy. The result raises the possibility that some glucagon-like […]
Paleontologists Spent 20 Years Dating Thousands of Fossils – Here’s What They Found
How quickly sediment accumulates on the seafloor appears to be the key factor determining whether fossils from different time periods become mixed together. A single layer of marine fossils can look like a snapshot of one ancient community even when the organisms preserved side by side actually lived hundreds or thousands of years apart. For […]
