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 ...

Researchers analyzing over 20,000 patients found that very high levels of the inherited cholesterol particle Lp(a) dramatically raise the risk of stroke, cardiovascular death, and major heart complications. Because most people with elevated Lp(a) ...

NASA is testing a next-generation space computer chip that could give spacecraft the ability to operate far more independently in deep space. The radiation-hardened processor is showing performance levels hundreds of times beyond current spaceflight ...

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 ...

A groundbreaking Swedish study that tracked people for nearly 50 years has revealed when the body's physical decline quietly begins. Researchers found that fitness, strength, and muscle endurance start slipping around age 35, with the decline ...

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 . ...

Colorectal cancer is increasingly showing up in younger adults, with cases now appearing in people as young as their thirties -- often with no family history or warning signs. A major Swiss study analyzing nearly 100,000 cases over four decades found ...

A daily multivitamin may help slow biological aging, according to researchers studying older adults in a large clinical trial. After two years, participants taking multivitamins showed slower aging in several DNA-based "epigenetic clocks," with the . ...
