Researchers have revealed that so-called "junk DNA" contains powerful switches that help control brain cells linked to Alzheimer's disease. By experimentally testing nearly 1,000 DNA switches in human astrocytes, scientists identified around 150 that ...

In a rare and historic achievement, Children's Hospital Colorado successfully completed its first dual heart and liver transplant in a pediatric patient. The life-saving surgery was performed on 11-year-old Gracie Greenlaw, whose congenital heart ...

Long before whales and sharks, enormous marine reptiles dominated the oceans with unmatched power. Scientists have reconstructed a 130-million-year-old marine ecosystem from Colombia and found predators operating at a food-chain level higher than any ...

A small tweak to mitochondrial energy production led to big gains in health and longevity. Mice engineered to boost a protein that helps mitochondria work more efficiently lived longer and showed better metabolism, stronger muscles, and healthier fat ...

A new bioluminescent tool allows neurons to glow on their own, letting scientists track brain activity without harmful lasers or fading signals. The advance makes it possible to watch individual brain cells fire for hours, offering a clearer, deeper ...

Researchers announced over 70 new species in a single year, including bizarre insects, ancient dinosaurs, rare mammals, and deep-river fish. Many were found not in the wild, but in museum collections, proving that major discoveries can still be ...

After injury, the visual system can recover by growing new neural connections rather than replacing lost cells. Researchers found that surviving eye cells formed extra branches that restored communication with the brain. These new pathways worked ...

New research reveals when glaciers around the world will vanish and why every fraction of a degree of warming could decide their fate.

Cosmic "touchdown airbursts" -- explosions of comets or asteroids above Earth's surface -- may be far more common and destructive than previously thought, according to new research. Unlike crater-forming impacts, these events unleash extreme heat and ...

Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded by future space observatories.
