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.

Under stress, bacterial RNA and proteins tell different stories
6+ hour, 41+ min ago (612+ words) Log into the student web Edit content at umu.se NEWS Researchers at Umeå University have identified stress conditions in which RNA and protein levels diverge in disease-causing bacteria. Under osmotic stress, they traced this mismatch to reduced protein production,…...
New Method Unlocks Molecular Secrets Trapped in Decades-Old Human Tissue Samples
9+ hour, 48+ min ago (428+ words) Recovering whole cells from decades-old preserved tissue could make hospital archives a richer source of molecular data. Imagine a volume labeled “Encyclopedia of Human Tissue” resting on a table. Inside might be information about how different cells appear in healthy…...
Collection policies | Genetic Medicines: From Genomic Discovery to Clinical Translation
1+ day, 6+ hour ago (186+ words) This Collection supports and amplifies research related to SDG 3: Good Health & Wellbeing. This Collection will explore the development and clinical translation of genetic medicines, spanning the journey from genomic discovery to therapeutic development and patient care. We welcome original research…...
New Computational Tool Flags the Tipping Points Where Genes Turn Disease
14+ hour, 4+ min ago (778+ words) Diseases rarely unfold in a smooth, predictable line. For patients and clinicians alike, the most consequential moments in an illness are often the abrupt ones: the day a stable tumor suddenly turns aggressive, the hour a mild respiratory infection tips…...
Macrophages move captured proteins onto their own surface during live-cell
14+ hour, 4+ min ago (781+ words) Macrophages, the sentinel cells of the innate immune system, have long been celebrated for their remarkable ability to engulf and process foreign material, from invading bacteria to the cellular debris left behind by dying tissue. A new study published in…...
Hidden Moss Worlds Thrive on China’s Degraded Karst Landscapes
14+ hour, 19+ min ago (96+ words) Beneath the cracked, chalky surfaces of southern China’s degraded karst terrain, an unexpected biological empire has been quietly holding the ground together. A new study of biological soil crusts—thin, living skins of mosses, lichens, algae, and cyanobacteria that bind…...
Cofilin-1 Dosage Governs Muscle Cell Differentiation and Fusion, Study
14+ hour, 19+ min ago (632+ words) Every time a muscle fiber forms, a single cell must perform one of the most dramatic architectural transformations in biology. A myoblast — a committed muscle precursor cell — has to abandon division, elongate, and then fuse with its neighbors to build…...
Cryo-EM Reveals How Polycomb Repressive Complex 1 Assembles, Works and
14+ hour, 32+ min ago (651+ words) In the crowded nucleus of every human cell, the two-metre stretch of DNA in each chromosome is constantly being read, folded and annotated by armies of protein complexes....
Biodegradable Hydrogel Beads Keep Beneficial Fungus Alive and Boost Pepper
14+ hour, 38+ min ago (657+ words) Beneficial fungi such as Trichoderma longibrachiatum have long been celebrated as natural allies of farmers, suppressing soil-borne pathogens and stimulating plant growth without the environmental baggage of synthetic agrochemicals....
Iron-Linked Cell Death May Explain Why Autism Risk Hits Male Mice Harder
16+ hour, 14+ min ago (55+ words) A single drug taken during pregnancy may leave sharply different fingerprints on the developing brains of boys and girls, and a new study points to an unexpected culprit: a form of iron-driven cell death that appears to strike the male…...
