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.

Fruit fly brain study reveals how working memory is written and switched off
8+ hour, 1+ min ago (657+ words) Researchers at NYU Langone Health have shown that fruit flies store short-term odor memories in a gated split attractor network of PFG and hΔK neurons, revealing a mechanism for working memory....
180 Early-Career Scientists Win $12.5 Million in Grants to Tackle Mental Illness
10+ hour, 12+ min ago (585+ words) The Brain & Behavior Research Foundation has awarded more than $12.5 million in two-year grants to 180 early-career scientists selected from 993 applications to advance research on depression, schizophrenia, and other brain and behavior disorders....
How Broadly Bat Viruses Use the ACE2 Receptor May Predict Pandemic Risk
10+ hour, 9+ min ago (85+ words) A new PLOS Biology study shows that the breadth of ACE2 receptor usage among bat sarbecoviruses predicts both their host range and how closely they are antigenically related to SARS-CoV-2. Subject of Research: ACE2 receptor usage breadth as a predictor of host…...
Severe Hand, Foot and Mouth Disease Outbreak in Vietnam Traced to a Single Introduction of Enterovirus A71 Subgenogroup B5
11+ hour, 12+ min ago (616+ words) A 2023 severe hand, foot and mouth disease outbreak in Vietnam was caused by a single introduction of enterovirus A71 subgenogroup B5 into a young population with almost no neutralizing antibodies, with no evidence of viral immune evasion....
Conserved Spike Epitopes Yield Antibodies That Neutralize Diverse Bat Sarbecoviruses
12+ hour, 8+ min ago (629+ words) Researchers have mapped conserved epitopes on the sarbecovirus spike protein that allow three monoclonal antibodies to neutralize a wide range of bat viruses and current SARS-CoV-2 variants....
AI Decodes the Hidden Grammar of the Genome’s Master Organizer CTCF
11+ hour, 41+ min ago (56+ words) A new computational framework called DeCTCF uses AI-predicted epigenomic features to sort more than 236,000 CTCF binding sites into 20 functional modules, revealing how the genome's master architectural protein performs different roles in different cell types. News Source: Juliet Wilcox. (October 11, 2026). AI…...
Bacterial Uracil in the Larval Gut Primes Adult Flies to Taste Microbial Danger
14+ hour, 11+ min ago (659+ words) New research in PLOS Biology reveals that bacterial uracil triggers gut ROS signaling and a single larval TrpA1-B neuron in fruit flies, permanently priming the adult taste system to reject food containing bacterial peptidoglycan....
Hidden World of Commensal Anelloviruses Mapped in Unprecedented Genomic Detail
14+ hour, 56+ min ago (662+ words) An expanded genomic reference built from 6,348 Chinese metagenomic samples has revealed 771 species-level anellovirus taxa, an eightfold increase in known diversity, and uncovered structured, immune-linked communities within the human anellome....
Lactate emerges as both warning sign and driver of kidney injury after heart surgery
15+ hour, 35+ min ago (97+ words) A new iScience study combining machine learning on over 6,500 patient records with rat and cell experiments shows that lactate is both a powerful predictor and an active mechanistic driver of acute kidney injury after cardiopulmonary bypass. Subject of Research: The…...
Gut Bacteria for Plants: Endophytic Microbes Shield Rice from Salt Stress
18+ hour, 15+ min ago (550+ words) Thai researchers found that salt-tolerant endophytic bacteria, especially the SHPP24 and SKPK29 isolates, significantly improved rice physiology, growth, and grain yield under severe salinity stress across two consecutive growing seasons....
