A newly identified prehistoric whale had unusual adaptations that may have allowed it to hunt along the seafloor millions of years ago. An ancient whale that lived millions of years ago had a skull so dramatically distorted that its face appeared pushed to one side. Its bony nostrils were displaced entirely to the left, and […]
CT Scans Reveal the Secret of a Mysterious 400-Year-Old Lock
X-ray scans cracked an Elizabethan padlock’s code, revealing how a centuries-old security mechanism worked without damaging an unusually well-preserved piece of maritime history. For more than 400 years, a brass combination lock recovered from a shipwreck off the Welsh coast kept its secret. Lost when a violent storm wrecked the Ann Francis, the remarkably well-preserved […]
Stonehenge’s Mysterious Six-Ton Stone Has Scientists Searching Across Britain
Stonehenge’s six-ton Altar Stone has led scientists from Wales to Scotland, yet even its most detailed geological examination has failed to reveal where it came from. Scientists have spent more than a century trying to determine where Stonehenge’s six-ton Altar Stone came from. Once thought to originate in Wales, the massive sandstone slab has since […]
Ancient Tomb Reveals That People Were Getting High on Cannabis 2,800 Years Ago
The oldest directly dated evidence of intoxicating cannabis use comes from a Scythian tomb, suggesting the plant’s mind-altering effects had a place in ancient burial rituals. About 1,000 cannabis seeds recovered from a princely tomb in southern Siberia could not, on their own, tell archaeologists whether anyone had used the plant to get high. Cannabis, […]
Scientists Warn of a Disturbing Rise in Vitamin K Deficiency Among American Newborns
Only about one in five infants diagnosed with vitamin K-related bleeding had received the shot, U.S. health records show. Babies are born with little vitamin K, leaving them vulnerable to bleeding that can cause permanent brain damage or death. A single shot helps protect against that danger. The American Academy of Pediatrics has recommended one […]
Blood Vessel Function Improved Just 60 Minutes After Taking This Anti-Aging Supplement
Blood vessel function improved within an hour of a supplement’s first dose in a small human trial, though lasting protection against cardiovascular disease remains unproven. What if protecting the heart and blood vessels requires more than treating traditional risk factors such as high blood pressure and cholesterol? Cardiovascular disease remains the world’s leading cause of […]
Scientists Discover New Form of Prostate Cancer
A newly discovered hereditary cancer risk could change how doctors identify vulnerable families. Researchers at the University of British Columbia have identified a previously unrecognized form of hereditary prostate cancer linked to a rare genetic mutation that can lead to aggressive disease at relatively young ages. The discovery could help doctors identify families with an […]
Scientists Warn: The World Has Less Than Four Years of Carbon Budget Left
Solar power, wind energy, and electric vehicles are reshaping global emissions trends, but a new scientific assessment reveals that the world’s remaining carbon budget is shrinking at an alarming rate. Global fossil fuel emissions are expected to fall slightly in 2026, but the world’s total carbon dioxide output is still projected to rise. A new […]
Mars May Not Be Dead After All, New Discovery Suggests
Gas above a Martian volcano may come from hidden magma, offering clues to the planet’s remaining heat and its potential to support life underground. Hydrogen chloride gas usually reaches its highest levels in Mars’s atmosphere during winter in the northern hemisphere, then mostly disappears in summer. Much of that seasonal pattern appears to follow the […]
A Universe Without Dark Matter? Radical New Model Challenges Modern Cosmology
An older universe could give unexpectedly mature early galaxies billions more years to grow, according to a model that also reproduces galaxy rotation without dark matter. To explain how galaxies rotate, the standard model of the universe relies on dark matter, an unseen source of gravity. A new paper published in Monthly Notices of the […]
