Astronomers have revealed the sharpest image ever captured of a filament in the cosmic web -- the enormous hidden structure connecting galaxies across the Universe. The glowing strand stretches 3 million light-years and links two galaxies from nearly ...

A major analysis of brain scans found that people with anxiety disorders have noticeably lower levels of choline, a nutrient crucial for healthy brain function. The strongest evidence appeared in the prefrontal cortex, the region tied to emotional .. ...

A stunning fossil discovery in Ethiopia shows that early Homo and a previously unknown Australopithecus species lived together around 2.6 to 2.8 million years ago. The find overturns the classic "ape-to-human" progression and paints human evolution . ...

A mysterious underwater fault near Ecuador has been producing nearly identical magnitude 6 earthquakes every five to six years, baffling scientists for decades. Researchers now believe the fault contains hidden "brake zones" where seawater and ...

A massive new dinosaur discovered in Thailand is rewriting Southeast Asia's prehistoric history. The newly named Nagatitan chaiyaphumensis was a colossal long-necked sauropod that weighed around 27 tonnes and lived more than 100 million years ago. .. ...

Scientists have uncovered evidence that serotonin -- the same brain chemical boosted by many antidepressants -- may actually worsen tinnitus. Using advanced light-based brain stimulation in mice, researchers identified a serotonin-driven circuit ...

A colossal valley near Mars's equator is revealing dramatic clues about the Red Planet's watery and volcanic past. Stretching roughly 1,300 kilometers, Shalbatana Vallis was carved billions of years ago when enormous floods of groundwater burst onto ...

NASA's Roman Space Telescope could expose a vast hidden population of neutron stars lurking unseen across the Milky Way. By detecting subtle shifts in starlight caused by gravity, the mission may identify and even weigh isolated neutron stars that .. ...

A casual conversation between graduate students helped spark a breakthrough in aging research at Mayo Clinic. Researchers discovered that tiny synthetic DNA molecules called aptamers can selectively attach to senescent "zombie cells," which are ...

Scientists at UC Santa Barbara have created a remarkable new material that works like a "rechargeable solar battery," storing sunlight inside tiny molecules and releasing it later as heat -- even long after the sun goes down. Inspired by reversible . ...
