Results tuned to biology
4Biology is a focused search engine built for biology students, researchers, educators, and lab managers. We combine multiple indexes, curated sources, and AI tools to surface publications, protocols, datasets, suppliers, and learning resources that matter to life scientists. Use the site to save time, find specialized resources, and get context-specific search results not optimized for general web traffic. Part of the 4SEARCH network of topic specific search engines.

Transposable Elements Drive the Birth of Vast Satellite DNA Repertoires in
1+ hour, 10+ 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,…...

Moth Olfactory Receptor Keeps the Same Chemical Codes Across Two Crop Pests
10+ hour, 29+ min ago (94+ words) Insects navigate their world largely through smell, relying on an intricate array of chemosensory proteins to detect everything from host plant volatiles to mating signals. Among these molecular sentinels are ionotropic receptors, or IRs, a family of receptors descended from…...
