“Zombie cells” become harder to clear with age, and a new study reveals why the immune system struggles to remove them. Researchers at Albert Einstein College of Medicine have identified a breakdown in protein recycling that helps explain why senescent cells, often called “zombie cells,” accumulate in aging tissues. In experiments involving older mice, restoring […]
Unexpected Discovery of Abnormal Antibodies Could Help Explain Childhood Cancer
Laboratory experiments show that antibodies associated with childhood cancer can enter cells and bind DNA repair proteins, suggesting a possible route by which the immune system could weaken genetic safeguards. Years before some children were diagnosed with cancer, their blood already contained antibodies directed against proteins that normally repair damaged DNA. Researchers in Norway have […]
Scientists Discover a Surprising Dental Benefit of Cranberry Juice
In a small human study, unsweetened pure cranberry juice was linked to slower plaque regrowth and lower acid production, hinting at a possible oral health benefit. Cranberry juice has a reputation for being tart, acidic, and often sugary, qualities that might seem poorly suited to protecting teeth. A small human study from the University of […]
Scientists Discover That Eating Peanuts Every Day May Help Protect the Aging Brain
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 […]
