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.

Cyclin gene evolution in Arabidopsis and Brassica links polyploid
2+ hour, 1+ min ago (951+ words) In a finding that could reshape how breeders approach one of the world’s most important oilseed crops, researchers at The University of Western Australia have completed the most comprehensive survey yet of cyclin genes across the mustard family, revealing that…...
Hybrid nanofluid blood flow modeled in ciliated porous concentric tubes
3+ hour, 25+ min ago (754+ words) Cilia are tiny, whip-like filaments that line many of the body’s internal passages, and when they beat in coordinated waves they can push fluid along without any external pump....
Two Ways to Read a Cell’s Master Switches Reveal Hidden Biases in Gene
3+ hour, 25+ min ago (849+ words) Transcription factors are the master regulators of the genome, the proteins that decide which genes are switched on, which are silenced, and ultimately what a cell becomes. Because they govern cell identity, development, and the progression of many diseases, researchers…...
FIMBRIN2 Drives ABA-Induced Stomatal Closure via Actin Remodeling in Guard
4+ hour, 33+ min ago (652+ words) When drought strikes, plants face an immediate dilemma: keep their leaf pores open to absorb carbon dioxide for photosynthesis, or seal them shut to conserve precious water. The answer lies in a sophisticated hormonal and cellular choreography that has fascinated…...
Worldwide study shows limits to how long humans can live
8+ hour, 4+ min ago (772+ words) There are few questions in science that grip the public imagination quite like the limits of human longevity, and a new study published in the journal Biogerontology now adds a substantial piece of evidence to one of the most contentious…...
New tool Dory analyzes differences in image-based chromatin tracing data
8+ hour, 37+ min ago (690+ words) Researchers at the University of Virginia and Yale School of Medicine have introduced a new computational method designed to detect structural differences in the three-dimensional organization of the genome between groups of cells, addressing one of the most pressing analytical…...
Gene family evolution and salivary gene expression track diet shifts in
9+ hour, 19+ min ago (758+ words) Aphids draining sap from a rose bush, bedbugs feeding on human blood, assassin bugs skewering prey, and water striders hunting insects on the surface of a pond all belong to a single insect order, Hemiptera....
Antarctic Bacterium Yields Kineochelins, a Novel Class of Iron-Binding
10+ hour, 27+ min ago (688+ words) In the frozen soils of James Ross Island, Antarctica, where temperatures hover near freezing and nutrients are vanishingly scarce, an unassuming bacterium has been quietly manufacturing a class of molecules no scientist has ever seen before....
Graph Transformer Puts Rare Cell States on the Map in Single-Cell Data
10+ hour, 51+ min ago (127+ words) Deep inside every tissue, some of the most consequential cells are also the hardest to find. They exist at vanishingly low abundance, appear only transiently within narrow spatial niches, or emerge briefly in response to stress and injury, yet they…...
Engineered genomic attachment sites for site-specific recombinases enable high-efficiency integration in plants and human cells | Nature Biotechnology
1+ day, 13+ hour ago (710+ words) Nature Biotechnology (2026) Cite this article The luciferase activity was measured using a Dual-Luciferase Reporter Assay System (Promega) according to the manufacturer’s protocol. All assays were performed in white 96-well plates (Sangon Biotech, 400 µl, high adsorption) with a SuperMax 3000AL luminometer (Flash…...
