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.

Mussel Brains Reveal How Nervous Systems Survive Oxygen Starvation and
just now (671+ words) When the tide recedes from a rocky Mediterranean shore, the mussels clinging to the stones simply close their shells and wait. Inside those shells, oxygen levels plummet, carbon dioxide accumulates, and the entire body shifts into a biochemical holding pattern…...
Dual-State Structures Reveal How Drugs Switch the Immune Receptor GPR84
37+ min ago (69+ words) A receptor long viewed as one of the more enigmatic members of the lipid-sensing G protein-coupled receptor family is now coming into sharp molecular focus. New research published in Experimental & Molecular Medicine describes how structural snapshots of GPR84, captured in distinct…...
First NAM Population in Italian Ryegrass Pinpoints Genes Behind Seed
51+ 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…...
Enzymes and Fermentation Team Up to Strip Bad Flavors from Mealworm Protein
52+ min ago (675+ words) Edible insects have been heralded as one of the most sustainable protein sources on the planet, but there has always been an awkward catch: many people simply do not like the way they smell or taste....
Moth Olfactory Receptor Keeps the Same Chemical Codes Across Two Crop Pests
59+ 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…...
Cryo-EM Captures Hidden Pre-Active State That Switches On the Brain’s
1+ hour, 56+ min ago (663+ words) For decades, neuroscientists have marveled at the sheer speed of communication in the brain, and much of that speed depends on a single family of proteins known as AMPA receptors....
How Plants Strike a Balance Between Immune Power and Growth
2+ hour, 56+ min ago (79+ words) Plants cannot run from their enemies, so they have evolved an extraordinary arsenal of molecular sentinels that detect invading pathogens and launch defences within minutes. Yet this vigilance comes at a price: every burst of immune activity diverts energy, nutrients…...

Placenta Gene PHLDA2 Hits Female Fetuses Harder, Mouse Study Finds
2+ hour, 56+ min ago (607+ words) Deep inside the mammalian placenta, a quiet genetic tug-of-war shapes how much a growing fetus asks of its mother....
Environmental Stress May Have Loosened DNA Repair Rules on the Y Chromosome
3+ hour, 45+ min ago (795+ words) A provocative new hypothesis published in the open-access journal Epigenetics Communications proposes that prolonged environmental stress in the ancient southern Levant may have transiently loosened the normally rigid rules of DNA repair in one specific human Y-chromosome lineage, allowing rare…...
