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.

Active living matter reveals irreversible symmetry breaking as defects form
16+ hour, 33+ min ago (853+ words) A new study of swarming bacteria and human bronchial epithelial cells has uncovered a hidden asymmetry in the microscopic events that shape living matter: the birth and death of topological defects do not unfold as mirror images of one another....
New T2T Bread Wheat Genome Assembly Enables Detailed Satellitome Mapping
20+ hour, 20+ min ago (97+ words) Bread wheat’s genomic “dark matter” has come into sharper focus in a new analysis that maps thousands of repetitive DNA sequences across all 21 chromosomes. Using the first complete, gap-free telomere-to-telomere assembly of the bread wheat genome, researchers have re-examined the…...
CnQuant Enables High-Resolution Chromosomal Copy Number Profiling for
20+ hour, 55+ min ago (83+ words) A new open-source software platform could bring high-resolution chromosome analysis closer to routine cancer care, allowing clinicians to inspect tumor DNA for missing, duplicated and amplified genomic regions through an interactive interface rather than relying on static laboratory reports. Called…...
