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.

Antarctic Bacterium Yields Kineochelins, a Novel Class of Iron-Binding
3+ hour, 56+ 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
4+ hour, 20+ 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, 7+ 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…...
Antarctica is home to microbes found nowhere else on Earth
2+ day, 8+ hour ago (759+ words) Antarctic soils harbor microbes found nowhere else on Earth, revealing a hidden world of life uniquely adapted to the continent’s extreme conditions. A new study has found that there are microbes in Antarctica’s soil that don’t exist anywhere else on…...

Even ancient bacteria possessed intercellular communication structures like humans today
3+ day, 3+ hour ago (504+ words) Communication between cells in plants, animals and humans takes place via specialised connecting structures. An international team led by biologists from Heinrich Heine University Düsseldorf (HHU) and involving the University of Tübingen has now discovered how the regulation of very…...
