1+ hour, 19+ min ago (72+ words) Hypoxia-inducible factor 1 alpha, or HIF1α, has long been celebrated as the master switch that allows cells to sense and survive low-oxygen conditions, a discovery that earned the 2019 Nobel Prize in Physiology or Medicine. In the intestine, this transcription factor is far…...
Deep Learning Cuts Brain MRI Scans to Under 100 Seconds in Feasibility
4+ hour, 17+ min ago (764+ words) Magnetic resonance imaging has long been the gold standard for peering into the human brain, but it has always demanded one precious commodity that many patients simply cannot spare: time....
Transposable Elements Drive the Birth of Vast Satellite DNA Repertoires in
4+ hour, 23+ 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,…...
New Rust Toolkit Supercharges Sex Determination Studies in Non-Model
7+ hour, 8+ 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....
Different video game genres alter brain activity and enhance cognition in unique ways
23+ hour, 39+ min ago (748+ words) Playing different types of video games can improve a person’s cognitive abilities and alter how their brain operates at rest. A new study reveals that fast-paced action games and turn-based strategy games both enhance mental performance, but action games lead…...
