Astronomers may have finally cracked one of the universe's biggest mysteries: how black holes grew so enormous so fast after the Big Bang. New simulations show that early, chaotic galaxies created perfect conditions for small "baby" black holes to go ...

Webb's latest image of the Helix Nebula reveals a dramatic close-up of a dying star shedding its outer layers. The detailed view highlights glowing knots of gas shaped by fast-moving stellar winds colliding with older material. Changes in color trace ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By splitting an entangled group of atoms into separate clouds, they were able to measure electromagnetic fields more precisely than . ...

A 5,500-year-old skeleton from Colombia has revealed the oldest known genome of the bacterium linked to syphilis and related diseases. The ancient strain doesn't fit neatly into modern categories, hinting at a forgotten form that split off early in . ...

Cancer doesn't evolve by pure chaos. Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes--massive genetic shifts that help tumors grow, adapt, and survive treatment. . ...

Alzheimer's may destroy memory by flipping a single molecular switch that tells neurons to prune their own connections. Researchers found that both amyloid beta and inflammation converge on the same receptor, triggering synapse loss. Surprisingly, .. ...

A Roman-era skeleton discovered in southern England has finally given up her secrets after more than a decade of debate. Known as the Beachy Head Woman, she was once thought to have roots in sub-Saharan Africa or the Mediterranean--an idea that ...

Long before farming took hold, ancient Indigenous peoples of the American Southwest were already shaping the future of a wild potato. New evidence shows that this small, hardy plant was deliberately carried across the Four Corners region more than 10 ...

Researchers have developed a technique that allows them to carve complex three dimensional nanodevices directly from single crystals. To demonstrate its power, they sculpted microscopic helices from a magnetic material and found that the structures . ...

Pancreatic cancer may evade the immune system using a clever molecular trick. Researchers found that the cancer-driving protein MYC also suppresses immune alarm signals, allowing tumors to grow unnoticed. When this immune-shielding ability was ...
