Scientists reveal why some workout recovery tricks can backfire
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.

Cornell scientists identify rare human genetic disorder in two unusually long-legged cats
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.

The secret to easier exercise as an adult may start in childhood
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.

Scientists may have overlooked a hidden Alzheimer's culprit for decades
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 finally solved the mystery of the Moon’s two faces
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.
