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.
A two-season, two-year survey across 200 grids in China’s Huangshan Mountains found that rainfall, vegetation productivity and latitude were associated with amphibian diversity, while species turnover accounted for nearly 98% of spatial differences. Subject of Research: Environmental correlates of amphibian alpha and…
A near-atomic-resolution structure shows how a recessed pocket assembled from four hantavirus glycoproteins recognizes protocadherin-1 and how two distinct classes of neutralizing antibodies block receptor engagement.
Molecular dynamics simulations show that protonation at two conserved sites in MmpL3 favors distinct conformations and changes how a key mycobacterial cell-wall lipid is positioned.
Cross-sectional human profiling and laboratory experiments indicate that Bacteroides fragilis outer membrane vesicles can trigger autophagy and reduce Pseudomonadota colonization in mouse skin. The vesicles did not significantly inhibit bacterial growth when tested directly in vitro, arguing against a simple…
fastGxE found 25 candidate gene–environment interaction loci across 99 UK Biobank traits, including 16 loci not previously associated with these interactions.
An analysis of 879,461 adult genomes found approximately 4.3 million to 5.3 million small variants per person, alongside de novo mutations, copy-number changes and disease-associated variants whose interpretation varies by ancestry and data quality.
The present study does not itself demonstrate disease prevention or clinical benefit in humans. The researchers reanalyzed an older genome-wide association study dataset from B. glabrata snails experimentally challenged with S. mansoni. The analysis identified association signals at LG5R and LG11L. LG11L contains a cluster…
A pilot study in 36 pigs found measurable Neat1 expression in blood, saliva and hypothalamus, but its response to psychosocial stress was inconsistent and insufficient to validate it as a welfare biomarker. Subject of Research: Measurement of stress-associated Neat1 expression in blood, saliva…
Genome-wide and reduced-representation sequencing found broad genetic connectivity in Antarctic toothfish but also temporal diversity loss and elevated inbreeding in the Ross Sea.
The area supported a relatively stable population of four to six adult Iberian lynx, including two to three males and two to three females, and 105 to 223 black kite breeding pairs. Black kites represented 82–90% of the local raptor assemblage. The two…
