1+ hour, 25+ min ago   (403+ words) A piece of burnt coconut helped scientists uncover a species new to science in Sri Lanka. The discovery began more than 2 decades ago, when researchers trapped two unusual mice in the Knuckles Mountain Range. The animal has now been formally…...

1+ hour, 4+ min ago   (707+ words) Detecting dangerous bacteria in a patient’s sample can take hours or even days, and the fastest molecular tests demand expensive laboratory infrastructure and highly trained staff....

1+ hour, 36+ min ago   (744+ words) For decades, the central obstacle to testing therapies that slow human aging has been painfully simple: aging takes decades to measure. A drug that genuinely delays the biological processes of aging would need years, often a lifetime, of follow-up before…...

1+ hour, 46+ min ago   (117+ words) High on the Qinghai-Tibet Plateau, where flocks of Black Tibetan sheep graze at altitudes of roughly 3,000 meters in China’s Qinghai Province, a routine husbandry practice is quietly rewriting the biochemical identity of one of the region’s most prized meats. Castration…...

1+ hour, 57+ min ago   (597+ words) The genomes of true frogs have long puzzled geneticists. Amphibians are famous for carrying some of the largest and most repetitive genomes among vertebrates, and yet the detailed architecture of their repetitive DNA has remained poorly explored compared with mammals,…...

1+ hour, 57+ min ago   (68+ words) Aging has become a product. Across North America and Europe, companies now sell direct-to-consumer epigenetic tests that estimate a customer’s biological age from DNA methylation patterns, often bundled with supplements and lifestyle programs marketed as capable of slowing or even…...

2+ hour, 19+ min ago   (537+ words) Deep in the steaming runoff channels of Taiwan’s hot springs, a group of microbes has been quietly rewriting the rules of photosynthesis. These are the far-red light-utilizing cyanobacteria, or FRLCyano, organisms capable of extending oxygenic photosynthesis beyond the visible spectrum…...

2+ hour, 30+ min ago   (75+ words) Rare cells punch far above their weight in biology. Populations that make up less than one percent of a tissue can drive tumor progression, immune evasion, drug resistance, and relapse, while others mark the first steps of lineage commitment or…...

2+ hour, 43+ min ago   (529+ words) Neuroscientists can now record electrical storms of activity from tens of thousands of neurons at once, but a stubborn bottleneck has long stood between the raw data and discovery: turning enormous three-dimensional calcium imaging videos into clean, trustworthy lists of…...

3+ hour, 33+ min ago   (83+ words) When the first fish lineage crawled onto land some 375 million years ago, its fins had to be remodeled into limbs capable of bearing weight. Evolutionary biologists have long focused on the genes that pattern the skeleton—Hox clusters, Sonic hedgehog,…...
