A major study found that several cancers are rising faster among younger adults in England, even as smoking, diet, and other established risk factors have generally improved. Excess weight explains only part of the increase, leaving scientists searching for other possible causes, including changes in the gut microbiome and early-life exposures.
Ice baths, massages, compression garments, and recovery supplements promise faster muscle recovery, but research suggests their benefits are often overstated, and some techniques may even undermine long-term gains. Scientists say the most effective recovery methods are far simpler and cheaper: getting enough sleep, eating well, and giving muscles time to rebuild.
Two unusually long-legged cats have helped scientists uncover the first genetically confirmed cases of Marfan syndrome in domestic felines. Researchers at Cornell University discovered that the brothers carried two altered copies of a gene linked to the rare connective tissue disorder, which can affect the eyes, heart, and blood vessels. Surprisingly, the cats survived into adulthood because their genetic mutation still allowed some normal function.
Exercise during childhood could have a surprising lifelong benefit, potentially making physical activity less exhausting in adulthood. In a study involving guinea fowl, researchers discovered that birds accustomed to carrying weights while growing up could carry those weights as adults without using extra energy, while untrained birds burned 23% more.
For decades, scientists have focused on amyloid beta as a major culprit behind Alzheimer’s disease, spending billions of dollars developing treatments that have often delivered disappointing results. Now, researchers at UC Santa Cruz are drawing attention to a largely overlooked peptide called P3 that could also play a role in the disease. Previously believed to be harmless, P3 can form harmful-looking protein clumps even faster than amyloid beta and may also damage brain cells.
Scientists may have solved a long-standing mystery about why the Moon’s two sides are so different, using samples collected from its farside for the first time. Their findings suggest that uneven heating from Earth's gravitational pull drove enormous flows of ancient magma, creating the dramatically different lunar landscapes we see today.
Scientists have discovered a protein that may help harmful aging cells hide from the immune system, allowing them to accumulate and fuel age-related health problems. Blocking the protein in mice reduced these cells and inflammation while improving blood sugar regulation and strength, offering a promising new direction for anti-aging research.
Until now, the alien white-hot worlds of exoplanets have been depicted as circular, but new research has revealed the true shape of their atmospheres to be a deformed sphere rather than a perfect circle.
The two warmest time periods on Earth in the past 140 million years drove both mass extinctions and explosions in plant diversity, according to researchers in Australia and Austria who say this could explain how flowering plants became dominant among land plants. The study, published in Nature Plants, examined fossilized pollen and spores to show that the mid-Cretaceous and early Cenozoic periods of extreme global warmth were central to plant evolution. This applies not only to flowering plants, but also to the other main land plant groups.
A massive prehistoric snake discovered in India may have rivaled the largest snake ever known. Called Vasuki indicus, the 47-million-year-old giant could have reached up to 50 feet long, making it comparable to the legendary Titanoboa. Scientists believe its enormous body made it a slow-moving ambush predator, similar to a modern anaconda.
