Chemotherapy Speeds One Aging Marker in Breast Cancer but Leaves Epigenetic
3+ hour, 2+ min ago (520+ words) A new study is challenging one of the most common assumptions in the fast-growing field of biological aging research: that the different blood tests used to measure how fast a person is aging are, at some level, measuring the same…...
New Sequencing Method Maps RNA Isoforms Across Brain Cells With Single-Cell
3+ hour, 49+ min ago (529+ words) Every cell in the brain carries essentially the same genome, yet the same gene can produce a startling variety of RNA molecules. Through a process called alternative splicing, segments of a gene’s transcript can be included, skipped, or rearranged, generating…...
Seaweed-Derived Coating Matches Heparin at Keeping Blood From Clotting
5+ hour ago (628+ words) A coating built from red seaweed could soon replace one of medicine’s most indispensable yet most fragile ingredients....
AI Translates Light Microscopy Into Electron-Microscope Detail to Speed
5+ hour, 41+ min ago (534+ words) Mapping the wiring of the brain at nanometer resolution has long demanded a punishing trade-off: electron microscopy can reveal every synaptic cleft and organelle, but imaging even a cubic millimeter of neural tissue this way takes months or years of…...
Cicada Genomes Decoded to Safeguard a Traditional Medicine’s Future
6+ hour, 38+ min ago (55+ words) In the world of traditional Chinese medicine, few raw materials are as quietly ubiquitous as Cicadae Periostracum, the papery slough that cicadas abandon when they molt from nymph to adult. For centuries, this discarded exoskeleton has been prescribed for sore…...
Engineered Viruses Light Up Bacteria in Minutes by Releasing Reporter
7+ hour, 6+ 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....
Proteomic Aging Clocks Enter the Clinic in Landmark Phase 2a Geroprotection
7+ hour, 38+ 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
7+ hour, 59+ 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,…...
Machine Learning Meets X-Rays to Reveal the Hidden Architecture of Pea
8+ hour, 45+ min ago (95+ words) Every seed is a masterpiece of biological engineering, a compact package in which molecular order and cellular design are woven together to protect and nourish a future plant. For scientists trying to understand how crops such as the yellow pea…...
Mussel-Inspired Coating Keeps Tiny Artificial Lungs Clot-Free
9+ hour, 56+ min ago (676+ words) For the smallest and most fragile patients in intensive care, the difference between survival and decline often comes down to a few milliliters of oxygen. Preterm and term newborns who develop respiratory distress syndrome frequently need mechanical ventilation, and in…...
