Scientists may have finally found how Alzheimer’s kills brain cells
Researchers have identified a previously overlooked mechanism of brain cell death that appears to play a major role in Alzheimer’s disease and frontotemporal dementia. The finding could lead to new treatments aimed at slowing neuron loss by interruptin…
Record-breaking ocean drilling reveals why Japan’s 2011 tsunami was so deadly
Scientists have uncovered a hidden weakness beneath the Pacific Ocean that helps explain why Japan’s catastrophic 2011 earthquake and tsunami became so devastating. By drilling deeper into the seafloor than ever before, researchers discovered a thin, s…
Ancient bees turned tooth sockets into tiny nurseries 20,000 years ago
A stunning fossil discovery shows that ancient bees used the empty tooth sockets of mammal bones as tiny nests after owls scattered the bones across a cave floor 20,000 years ago. It’s the first known evidence of bees nesting inside animal bones, revea…
Scientists discover the deep sleep circuit that builds muscle, burns fat, and boosts the brain
Researchers have identified the brain circuitry that links deep sleep with the release of growth hormone, revealing how the two regulate each other. The newly discovered feedback loop helps explain why poor sleep can interfere with growth, muscle repai…
NASA’s Hubble spots a stellar sparkler for the Fourth of July
NASA’s Hubble Space Telescope has captured a spectacular red, white, and blue view of one of the Milky Way’s oldest star clusters to celebrate the nation’s 250th anniversary. Hidden within the ancient cluster are clues to how exploding stars helped tra…
NASA’s Hubble captures a crimson stellar nursery sparkling with blue and white stars
Hubble has captured a spectacular view of LH 95, where about 2,500 young stars are still on their journey to becoming full-fledged stars. Scientists discovered these growing stars can keep pulling in gas and dust for millions of years, extending an imp…
NASA’s Hubble captures a star-spangled sea of 500,000 stars
Celebrating the United States’ 250th anniversary, NASA released a stunning Hubble portrait of Messier 3, an ancient globular cluster with more than 500,000 stars. The remarkable cluster is helping scientists unravel the Milky Way’s past thanks to its r…
The secret to healthy aging may be hidden in your blood
Some people live past 100 with remarkable health, and researchers may have uncovered one reason why. A new study found that centenarians have a unique chemical “fingerprint” in their blood that sets them apart from normal aging, including unusual patte…
A hidden weakness in deadly cancers could lead to powerful new treatments
A UCLA study has identified a hidden Achilles’ heel in aggressive small cell cancers that have resisted new treatments for decades. Scientists found that tumors lacking the RB gene become critically dependent on the protein E2F3 for survival. Blocking …
