Search the life sciences
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.

Hidden Fungus Rewires Rice Root Chemistry to Summon Nitrogen-Fixing Bacteria
57+ min ago (774+ words) Researchers found that an endophytic fungus alters rice root exudates, enriching p-hydroxyphenylacetic acid to recruit nitrogen-fixing Enterobacter bacteria that boost rice biomass and nitrogen accumulation....
ResolVI cleans up noisy spatial transcriptomics data after segmentation goes wrong
57+ min ago (77+ words) A new probabilistic deep learning model called ResolVI corrects misassigned RNA molecules and batch effects in spatial transcriptomics data, sharpening cell-type identification across brain, liver cancer and colitis datasets. Subject of Research: A probabilistic deep learning model that corrects segmentation…...
Minimalist Phage Ptero Reveals the Bare Essentials of Bacterial Attack
57+ min ago (544+ words) Researchers in Australia have characterized phage Ptero and a family of thirteen minimalist bacteriophages whose stripped-down infection machinery reveals the core elements phages use to recognize and kill diverse Klebsiella hosts....
Shrubby Cinquefoil Mitochondrial Genomes Reveal Hidden DNA Traffic Between Cell Compartments
1+ hour, 15+ min ago (58+ words) The first complete mitochondrial genomes of Dasiphora fruticosa and D. glabra reveal stable gene cores, lineage-specific repeats, and extensive DNA transfer between cellular compartments. Subject of Research: Comparative mitochondrial genomics of the alpine shrubs Dasiphora fruticosa and D. glabra News Source: Gavin…...
AI Reads Protein Shapes to Unmask Bacterial Weapons
2+ hour, 31+ min ago (557+ words) A new multimodal deep learning framework called GeoEPred combines protein language model semantics with predicted 3D structures to more accurately identify the virulence effector proteins secreted by Gram-negative bacteria....
Living Near Livestock Farms Linked to Drug-Resistant Genes in Household Dust
2+ hour, 40+ min ago (770+ words) A large metagenomic study of Iowa homes finds that bedroom dust contains more antimicrobial resistance genes when residences sit closer to intensive livestock operations....
Wild Rice Gene Recruits Nitrogen-Fixing Bacteria to Boost Crop Efficiency
2+ hour, 40+ min ago (644+ words) Researchers have shown that a single receptor-like kinase gene inherited from wild rice can restore nitrogen-fixing root bacteria lost during domestication, boosting nitrogen-use efficiency and yield traits in cultivated rice....
Ancient Jumping Genes Help Explain How DNA Variants Shape the Human Cortex
3+ hour, 16+ min ago (777+ words) A massively parallel reporter assay of 9,092 cortical-structure-associated variants reveals that Alu retrotransposons, Wnt signaling and transcription factor expression jointly determine how noncoding DNA shapes the human cortex....
Treatment pulses reshape nutrient landscapes and decide whether resistant mutants escape
3+ hour, 3+ min ago (600+ words) A yeast-based therapy-mimicry assay paired with a digital twin reveals that intermittent treatment pulses control resistance escape by reshaping spatial nutrient gradients, defining a narrow therapeutic sweet spot....
New Matrix Method Captures Selection at Genes With Many Alleles
3+ hour, 3+ min ago (685+ words) Researchers have developed a matrix-based framework that models and estimates selection at multiallelic loci, capturing regimes such as heterozygote advantage directly from allele frequency time-series data....
