A daily serving of peanuts may improve insulin sensitivity in the aging brain, potentially supporting memory. Peanuts may offer more than a convenient source of protein and healthy fats. New research suggests that eating them regularly could help the aging brain respond more effectively to insulin, a hormone that plays an important role in memory, […]
From 54% to 100%: Scientists Reveal a Potential Breakthrough in Quantum Technology
Scientists have proposed a surprisingly simple way to improve photon absorption using specially engineered waveguides, potentially making future quantum technologies far more efficient. Quantum technologies depend on a process that remains surprisingly unreliable: transferring a single photon between two quantum bits, or qubits. With conventional methods, the receiving qubit successfully absorbs the photon only about […]
After 150 Years, Scientists May Have Solved the Mystery of Westminster Abbey’s Roman Coffin
Radiocarbon dating and traces of a vanished wooden coffin suggest that a Roman sarcophagus at Westminster Abbey became the final resting place of a medieval abbot. A Roman stone coffin at Westminster Abbey bears the name of a wealthy Briton who lived nearly 1,700 years ago. Yet the skeleton found inside appears to belong to […]
Scientists Discover Mysterious 150,000-Year-Old Bone From an Extinct Human Relative in Chinese Cave
A search through more than 60,000 bone fragments uncovered the first confirmed Denisovan radius, a forearm bone offering rare clues to how these ancient human relatives were built. A forearm fragment from a cave in southwest China combines features resembling those of Neanderthals and modern humans, yet it belonged to neither. Proteins preserved in the […]
Scientists Trap a Rare-Earth Metal in a Molecular Cage, Unlocking a Strange New State
Molecular cages helped chemists remove one electron from terbium, making an unusual form easier to study for possible uses in quantum computing and advanced sensors. Rare-earth metals are essential to modern technologies, from smartphones and high-performance magnets to advanced medical devices. Yet separating these valuable elements remains a major challenge because many share remarkably similar […]
Why Do We Have Necks? Scientists Uncover a 380-Million-Year-Old Evolutionary Twist
The first necks may owe more to the beginnings of walking than to looking around, according to models showing how little our early ancestors could move their heads. In fish, the shoulders attach directly to the skull, so looking left or right means turning the whole body. Some of the animals making the transition from […]
Tiny Magnets Implanted in Muscles Are Giving Prosthetic Hands a Remarkable New Ability
Tiny magnets implanted in muscles are helping a prosthetic hand feel like it is opening and closing naturally. You can close your eyes, make a fist, or reach for an object without ever needing to look at your hand. That seemingly effortless ability depends on a hidden sense called kinesthesia, which tells the brain how […]
“Strangest of Its Kind”: Scientists Uncover a Bizarre Bacterial Self-Destruct Switch
An unusual bacterial defense uses DNA to switch on toxin production, suggesting a new way to build molecular tools that control genes. nb An infected bacterium can protect its neighbors by destroying itself before the virus inside it has a chance to multiply. Bacterial immune systems called retrons trigger this sacrifice when they detect particular […]
Scientists Discover a Strange Insect in the Himalayas Where No One Expected It
A newly identified Himalayan wormlion challenges the idea that its genus lives only in the tropics, raising the possibility of undiscovered relatives on nearby mountain slopes. In rain-sheltered patches of sand and soil on the southern slopes of the Himalayas, wormlion larvae build funnel-shaped pits to catch prey. Larvae belonging to this group were first […]
Scientists Reverse 60 Years of Aging in Human Cells, Turning 80-Year-Old Cells Into 20-Year-Olds
Cells from an 80-year-old were reprogrammed to a molecular age below 20, and the slow-motion reset could help reveal how cellular rejuvenation works. What if scientists could turn back the biological clock of an 80-year-old human cell, making it behave like one from someone younger than 20? Researchers in Germany have accomplished just that, reversing […]
