Proteomic Aging Clocks Enter the Clinic in Landmark Phase 2a Geroprotection
11+ 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…...
Transposable Elements Drive the Birth of Vast Satellite DNA Repertoires in
32+ 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,…...
Mole-Rat Genes Evolving Faster Than Expected Reveal Secrets of Subterranean
3+ hour, 40+ 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…...
Nanoparticles Emerge as a Powerful New Weapon Against Cellular Aging
4+ hour, 24+ min ago (87+ words) Cellular senescence, one of the most closely studied hallmarks of aging, has long been a paradox in biology. On the one hand, it protects organisms by halting the division of damaged cells that might otherwise become cancerous. On the other,…...
New Fellowship Aims to Fuse Research and Extension for Future Animal
5+ hour, 52+ min ago (640+ words) The University of Tennessee Institute of Agriculture has unveiled an ambitious new fellowship designed to reshape how the next generation of animal science professionals is trained. Known as F.U.S.E....
First NAM Population in Italian Ryegrass Pinpoints Genes Behind Seed
9+ hour, 43+ min ago (651+ words) Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grasses in temperate agriculture, prized for its rapid growth, high digestibility and adaptability to intensive grazing and cutting systems. Yet behind its agronomic value lies a stubborn problem…...
Biobots arise from the cells of dead organisms − pushing the boundaries of life, death and medicine
9+ hour, 49+ min ago (334+ words) Given the right conditions, certain types of cells are able to self-assemble into new lifeforms after the organism they were once part of has died....
Scientists Bred “Super-Athlete” Mice for 30 Years – What Happened Was Unexpected
17+ hour ago (228+ words) A study involving 100 pairs of mice produced unexpected results that surprised researchers....
Why Laboratory Cell Models Matter in Modern Medical Research
1+ day, 1+ hour ago (350+ words) Many diseases begin with changes that occur at the level of individual cells. Genetic mutations, altered signaling pathways, and abnormal responses to environmental factors can all contribute to disease development. Developing a new medicine involves extensive testing before a potential…...
Scientists Can Now Watch 'Conversations' Between Cells Across The Body of a Living Animal
1+ day, 3+ hour ago (209+ words) Biology – the study of living things – can admittedly be a little reductive at times....
