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 identify crucial steps that initiate DNA replication
4+ hour, 16+ min ago (599+ words) Scientists have uncovered a molecular sequence that helps cells decide when to begin copying their DNA, revealing how a dormant replication machine is converted into an active engine for genome duplication....
Diverse Legume Defence Signals and Clustered Receptors Co-Evolved from
4+ hour, 26+ min ago (72+ words) A hidden network of plant peptide hormones may be giving legumes a far more sophisticated immune system than scientists previously recognized. In a study published in Nature Plants, researchers report that soybean produces a surprisingly diverse family of defence-activating peptides…...
Scientists Develop Real-Time Control Systems for Engineered Biology
6+ hour, 28+ min ago (510+ words) Engineered living cells are becoming miniature biological factories, capable of producing medicines, sustainable chemicals and other valuable products. They can also be designed to sense disease-related signals or respond to changing conditions inside the human body. Yet unlike machines built…...
Reusable brain architecture enables flexible cognition in mice and
13+ hour, 18+ min ago (607+ words) A new study suggests that the brain may build complex behavior in much the same way engineers build sophisticated machines: by combining reusable components rather than creating an entirely new system for every challenge. In experiments with mice and artificial…...
Protein-Foldamer Building Blocks Enable Self-Assembling Hybrid
13+ hour, 27+ min ago (555+ words) A new molecular design strategy is bringing two traditionally separate worlds of chemistry together: proteins, nature’s highly evolved molecular machines, and foldamers, synthetic molecules engineered to imitate the controlled shapes of biological polymers. In a study published in Nature Chemistry,…...
Scientists Build Living Circuit Boards Using Printed Bacterial Transistors
15+ hour, 27+ min ago (549+ words) Scientists have built living circuit boards by printing bacterial cells into carefully arranged patterns, creating reconfigurable biological computers that can perform logic operations without altering their genetic code....
High-resolution sequencing reveals genes shaping embryonic leaf development
15+ hour, 58+ min ago (603+ words) A new study is giving scientists an unusually detailed view of how the maize embryo builds its first leaves, using a technology capable of reading complete RNA molecules while preserving their precise locations inside developing tissue....
How plants silence jumping genes without harming essential genes
16+ hour, 59+ min ago (472+ words) Researchers in Japan have uncovered how plants distinguish dangerous “jumping genes” from essential genes when establishing DNA methylation, a chemical marking system that can silence genetic material without altering the underlying DNA sequence....
Schisandrin Lignans Stabilize GPX4 to Suppress Ferroptosis in Drug-Induced
17+ hour, 43+ min ago (57+ words) Drug-induced liver injury, one of the most unpredictable complications of modern pharmacotherapy, may be driven by a molecular failure that scientists are now learning to prevent. A study by Lan, Zheng, Li and colleagues reports that schisandrin lignans—bioactive compounds…...
Complete monk fruit genome reveals a gentle path to domestication
1+ day, 20+ hour ago (328+ words) | Newswise Newswise Complete monk fruit genome reveals a gentle path to domestication Monk fruit, or Siraitia grosvenorii, has long been used as both a medicinal plant and a source of zero-calorie sweetness. Yet modern production relies heavily on only a…...
