Cancer immunotherapy could become safer by stabilizing the cells that keep immune responses under control, an approach that reversed treatment-related inflammation in mice. Some cancer patients have to stop immunotherapy when their immune system starts attacking healthy tissue. These reactions can occur with drugs called immune checkpoint inhibitors, which help immune cells known as T […]
Scientists Ranked 20 Protein-Rich Foods on Health, Affordability, and Sustainability. One Surprising Food Came Out on Top
Tofu took the crown in a showdown of 20 protein-rich foods judged on health, affordability, availability, and their toll on the planet. Protein-rich foods can look very different when cost, access, health, and environmental impact all enter the picture. In a study published in Frontiers in Sustainable Food Systems, Dr. Chris Macdonald developed a framework […]
Popular Weight-Loss Drugs May Have a Surprising Effect on Your Brain
Popular weight-loss drugs may offer benefits that extend beyond metabolism, potentially helping preserve memory and other cognitive abilities. Medications used to treat obesity and type 2 diabetes may also influence memory and other cognitive abilities. But whether drugs such as semaglutide and tirzepatide can actually protect the brain remains uncertain, particularly after major clinical trials […]
Why Did Polynesians Suddenly Sail Across the Pacific After 1,700 Years? Scientists May Have Found the Answer
The real history behind Moana may be tied to a devastating drought that pushed Polynesian voyagers toward wetter islands and helped reshape human settlement across the Pacific. In Disney’s Moana, a young Polynesian girl sails beyond her island’s barrier reef to save her threatened home. Scientists have now uncovered evidence that a real environmental crisis […]
A Natural “Varnish” May Explain How 37,000-Year-Old Cave Art Survived
A new technique uses UV light to reveal a natural mineral varnish that may have helped preserve Chauvet Cave’s 37,000-year-old charcoal drawings. About 37,000 years ago, Paleolithic people entered a limestone cave in southeastern France and drew the animals around them, including cave bears, cave lions, bison, and horses. An ancient rockfall later sealed away […]
Scientists Just Found a Key Ingredient for Superconductivity at Room Temperature
Researchers have discovered that a key requirement for superconductivity can persist even at room temperature. Scientists searching for a superconductor that works at room temperature have identified a potential way forward. New research from Utrecht, Leiden, and Munich shows that electrons can form the pairs needed for superconductivity even at room temperature. The findings, published […]
Scientists Discover a Hidden Weakness in One of the Deadliest Cancers
Researchers have identified another potential approach to treating pancreatic cancer, with early experiments suggesting that blocking a protein could slow tumor growth and strengthen immune defenses. Pancreatic tumors can be surrounded by tissue so dense that it compresses blood vessels, making it difficult for nutrients to reach cancer cells. Even under these conditions, the cells […]
Could Vitamin B12 Hold the Key to Treating a Rare Genetic Disorder?
A search for genes linked to lifespan uncovered an unexpected connection between RNA splicing, metabolism, and developmental disorders. A mutation linked to a rare developmental disorder appears to interfere with more than the way cells process genetic instructions. Researchers discovered that it also disrupts vitamin B12-dependent metabolism in tiny roundworms. Supplying the vitamin restored key […]
Scientists Discover That Male and Female Hearts Age in Surprisingly Different Ways
A new study reveals surprising differences in how male and female hearts age at the cellular level. The heart may age very differently from one region to another. A detailed study of mouse hearts found that molecular signs associated with chronic inflammation and tissue scarring were concentrated around the aortic valves and aortic root, rather […]
James Webb’s Mysteriously Bright Galaxies May Finally Have an Explanation
Calculations suggest powerful ultraviolet light from young stars could sweep gas out of early galaxies while leaving dense star-forming regions intact, offering a clue to their mysterious brightness. The James Webb Space Telescope has revealed something unexpected about the early universe: bright galaxies were far more common just a few hundred million years after the […]
