Sediment beneath a secret Cold War base reveals a time when warmer summers helped push Greenland’s ice more than 60 miles back from its current edge. About 416,000 years ago, the ground beneath Greenland’s Camp Century was exposed to the sky. A new University at Buffalo-led study estimates that summers there were 4.7 degrees Celsius […]
Researchers Recover DNA from 7,000-Year-Old Leather, Revealing a Link to Goats Alive Today
Ancient DNA recovered from a remarkably preserved piece of 7,000-year-old leather is shedding new light on how prehistoric communities in Spain used domesticated animals. A 7,000-year-old piece of goat leather discovered in a Spanish burial cave has yielded ancient DNA, allowing scientists to trace a genetic connection between prehistoric livestock and goats living in Spain […]
Scientists Discover Climate Change May Have Stopped Earth’s Next Ice Age
A new glacial period may have been taking shape in the Arctic until global warming brought its slow advance to a halt. An ice cap in northern Canada began expanding about 2,000 years ago, according to research published in Science. The researchers argue that this growth marked the beginning of Earth’s next glacial period. […]
Strange Materials Make Waves Behave in Ways That Defy Expectations
Researchers have uncovered an unusual wave phenomenon that links engineered materials to principles found in ocean physics. Waves bouncing around an irregularly shaped space typically follow increasingly unpredictable paths. Scientists have now shown that certain materials can produce the opposite effect, guiding waves into stable, repeating patterns instead of chaotic trajectories. Researchers at the Advanced […]
Quantum Discovery Reveals Why More Powerful Lasers Can Actually Slow Atoms Down
Researchers have uncovered an unexpected way to control the movement of atomic layers in quantum materials. Scientists have discovered that two carefully timed laser pulses can move atomic layers in a quantum material more effectively than a single, more powerful pulse. Published in Nature Physics, the research shows that increasing light intensity can actually limit […]
Einstein Was Right Again: Scientists Discover Chemical Bonds That Defy Textbook Rules
Scientists have uncovered direct evidence that Einstein’s theory of relativity changes how atoms form triple chemical bonds in heavy elements. A fundamental rule of chemical bonding begins to break down when atoms become sufficiently heavy. Chemists at Brown University have found direct experimental evidence that Einstein’s theory of relativity changes the structure of triple bonds, […]
Scientists Discover a Hidden Eye Disease That Can Steal Your Night Vision
Researchers can spot signs of a newly identified genetic eye disease before light-sensing cells are lost by measuring how vision recovers in darkness. People with a newly identified genetic eye condition can see well for most of their lives before gradually losing peripheral vision and struggling to see at dusk or at night. The condition […]
A New Fiber Supplement Could Be a Game Changer for Millions With IBS
For people with IBS, a specially designed fiber blend could support a healthier gut without added pain or bloating, a trial alongside a low-FODMAP diet suggests. Cutting out foods that leave you bloated or in pain can bring welcome relief. For millions of people with irritable bowel syndrome, or IBS, however, a diet that eases […]
Could a Nasal Spray Stop Alzheimer’s Before Memory Loss Begins?
Protecting memory from Alzheimer’s may one day involve a nasal spray, with encouraging results in animals and evidence that its particles also protect human neurons grown in the lab. Alzheimer’s disease damages the connections that allow brain cells to communicate, threatening memory. A nasal spray containing tiny particles naturally released by cells has helped protect […]
