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.

Scientists use AI and nanotechnology to detect signs of life in space
2+ hour, 10+ min ago (1091+ words) Gold nanogaps and AI distinguish mirror-image amino acids, offering a possible route to compact instruments for the search for life. (CREDIT: The Brighter Side of News) A molecule’s shape can carry information that its chemical formula does not. Two amino…...
Bacteria regulate collective behaviour by mechanosensing cell–cell collisions
12+ hour, 17+ min ago (1570+ words) Nature Microbiology (2026) Cite this article Designs were generated using Klayout software and comprised 21 motifs arranged in three rows within a 40 × 22 mm area, corresponding to a standard coverslip size. Each motif featured a central inlet (diameter ~4 mm) connected radially to ~50 maze-like…...
Shotgun genetic engineering lets mammalian cells test millions of designs at once
44+ min ago (515+ words) Researchers have developed shotgun genetic engineering, a multiplexed strategy that screens millions of combinatorial genetic designs in mammalian cells within a single experiment....
Flexible Electrode Arrays Track the Same Brain Cells for Months as Their Codes Keep Shifting
23+ min ago (620+ words) Harvard researchers used tissue-like flexible electrode arrays to track the same mouse neurons for five months and showed that geometric realignment of drifting neural population dynamics keeps decoders accurate over time....
Bacteria Turn Bumps Into Signals to Escape Crowds and Conquer Mazes
1+ hour, 32+ min ago (699+ words) EPFL researchers have discovered that Pseudomonas aeruginosa senses collisions with neighboring cells and reverses direction, allowing bacterial populations to stay mobile in crowds and navigate maze-like environments far more effectively than mutants that cannot feel these bumps....
Cellular Program Behind Aging May Also Shape Embryos, CHARGE Syndrome Review Suggests
2+ hour, 55+ min ago (757+ words) A new review proposes that misregulation of developmental senescence, a transient embryonic cell-arrest program, may contribute to the congenital defects of CHARGE syndrome through its links to the chromatin remodeler CHD7....
Scientists Decode the Complete Chloroplast Genome of a Threatened Indonesian Rainforest Giant
2+ hour, 39+ min ago (63+ words) Researchers have assembled the first complete chloroplast genome of the Near Threatened dipterocarp Parashorea lucida, resolving its phylogenetic position and identifying molecular markers for conservation. Subject of Research: Complete chloroplast genome sequencing and phylogenetic analysis of the Near Threatened dipterocarp…...
Insulin-Sensing FOXO Protein Guards the Genome After DNA Damage
4+ hour, 3+ min ago (676+ words) New research in C. elegans shows that the FOXO transcription factor DAF-16 directly activates DNA repair genes to preserve genome integrity after genotoxic stress....
Giant Mitochondrial Genomes of Konjac Plants Revealed in Full for the First Time
3+ hour, 50+ min ago (647+ words) Researchers have assembled the complete mitochondrial genomes of two konjac species, Amorphophallus muelleri and Amorphophallus krausei, revealing giant circular genomes, conserved genes under purifying selection, and striking differences in RNA editing....
