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.

Bacterial Uracil in the Larval Gut Primes Adult Flies to Taste Microbial Danger
1+ hour, 22+ 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
2+ hour, 6+ 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
2+ hour, 46+ 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
5+ hour, 26+ 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....
Cell’s Cargo Trucks Caught Raising the Alarm When Protein Traffic Jams the ER
6+ hour, 41+ min ago (564+ words) New research in C. elegans reveals that ER-to-Golgi transport proteins actively couple excess cargo to the unfolded protein response in a cargo-selective manner. In the bustling logistics network of a living cell, few questions have proven as stubborn as this one:…...
Inside the Snake Gut: First Look at the Microbiome of a Himalayan Keelback
8+ hour, 32+ min ago (765+ words) The first metagenomic and metabolomic survey of the orange-collared keelback reveals a shared core gut microbiome with segment-specific differences in microbial taxa, carbohydrate-degrading enzymes, and amino acid metabolism across the snake's digestive tract....
Graph-Attentive AI Generates Rare Cells to Sharpen Single-Cell RNA Analysis
10+ hour, 58+ min ago (44+ words) A new graph-attention-based generative adversarial network called GARAGE produces realistic synthetic single-cell RNA-seq data that preserves rare cell types and improves downstream gene selection and clustering. News Source: Juliet Wilcox. (October 10, 2026). Graph-Attentive AI Generates Rare Cells to Sharpen Single-Cell RNA…...
Hairy Bittercress Conquers Japan’s Temperature Gradient With Four Genetic Clusters
13+ hour, 17+ min ago (88+ words) A genomic study of the invasive plant Cardamine hirsuta in eastern Japan reveals four genetic clusters with distinct climatic associations, including one broadly tolerant group and admixed individuals concentrated where cluster ranges overlap. Subject of Research: Genetic structure and climatic…...
Fossil Time Travelers? Scientists Challenge Claim That Oligocene Foraminifera Survived 10 Million Years
1+ day, 4+ hour ago (69+ words) A team of micropaleontologists argues that Oligocene fossils found in Miocene rocks in southern Spain were reworked by ancient currents rather than surviving far beyond their known extinction. Subject of Research: Debate over reworking versus range extension of Oligocene larger…...
Antibody Survey Reveals Widespread Flavi- and Paramyxoviruses Circulating in African Fruit Bats
1+ day, 6+ hour ago (463+ words) A large antibody-based survey across seven African countries finds high seroprevalence of flavi- and paramyxoviruses in fruit bats, linking large colony size to sustained viral circulation....
