33+ min ago   (587+ words) A team of researchers in China has sequenced the first complete mitochondrial genome of the jumping plant louse Bactericera gobica and, by combining it with nearly every other Triozidae mitogenome available, assembled the most comprehensive genetic dataset ever compiled for…...

2+ hour, 45+ 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…...

3+ hour, 6+ 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,…...

3+ hour, 6+ 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…...

5+ hour ago   (747+ words) For years, biologists catalogued small non-coding RNAs by counting how many of each type appeared in a sequencing run. That approach treated tiny RNA molecules as a census problem, and it worked well enough for microRNAs, the classical regulators of…...

5+ hour, 51+ min ago   (628+ words) A new open-source software package promises to transform how biologists hunt for the genetic switches that separate males from females in species with no reference genome....

6+ hour, 14+ min ago   (568+ words) Beneath the sun-baked soils of eastern and southern Africa, a family of rodents has quietly rewritten the rules of mammalian life. Naked mole-rats resist cancer, tolerate near-anoxic conditions and barely age. Damaraland mole-rats dig elaborate tunnel networks and live in…...
