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.

Formononetin fights cellular aging via FOS-driven pathway
4+ hour, 7+ min ago (726+ words) Aging has long been framed as an irreversible decline, a one-way street at the cellular level. But a new study published in the journal Biogerontology suggests that at least some of the hallmarks of cellular aging may be negotiable....
An extraordinary exploration of the extracellular environment
13+ hour, 6+ min ago (768+ words) Editorial from Development’s latest Special Issue - The Extracellular Environment in Development, Regeneration and Stem Cells, edited by Alex Hughes and Rashmi Priya. The post An extraordinary exploration of the extracellular environment appeared first on the Node. [Editorial from Development’s latest…...
Inflammation of brain blood vessels drives cortical superficial siderosis
6+ hour, 15+ min ago (713+ words) A routine brain scan finding long dismissed as a passive scar of old bleeding may in fact be the visible tip of an active, treatable inflammatory process, according to new research that could reshape how specialists diagnose and manage one…...
MetaCAT reconstructs quality microbial genomes and links them to host
9+ hour, 11+ min ago (741+ words) Metagenomics has transformed the study of microbial communities by allowing scientists to sequence the collective genetic material of entire ecosystems, from the human gut to ocean waters and soils. Yet a persistent bottleneck has limited what these vast datasets can…...
How genes and sex jointly shape cognition in Philadelphia youth cohort
14+ hour, 6+ min ago (876+ words) One of the largest genetic investigations of cognition ever conducted in young people has found that while boys and girls differ modestly on a range of cognitive tests, those differences are mirrored by real differences in how strongly genes shape…...
Warming and ammonium exposure in larvae shape adult frog outcomes
14+ hour, 8+ min ago (112+ words) The echoes of a tadpole’s early life can reverberate through a frog’s entire existence, but new research suggests those echoes are far stranger than scientists anticipated. In a long-term experiment conducted on the Iberian green frog (Pelophylax perezi), researchers Francisco…...
Multi-modal data integration uncovers predictive biomarkers for ovarian
17+ hour, 49+ min ago (742+ words) Precision oncology has long promised a future in which each patient’s tumor is read like a molecular instruction manual, with treatments selected to match the specific genetic faults driving the disease. Yet the promise has repeatedly stumbled in clinical trials,…...
Study maps tissue-specific aging trajectories across the human body
17+ hour, 59+ min ago (839+ words) Aging does not unfold at the same pace everywhere in the body, and one of the most ambitious attempts yet to quantify that asymmetry suggests that the deterioration of our tissues follows tissue-specific trajectories that are more coordinated than scientists…...
Damaged lysosomes undergo budding-type fission driven by mitochondrial
18+ hour, 27+ min ago (59+ words) In a discovery that reshapes how biologists think about cellular quality control, researchers have identified an entirely new mechanism by which cells repair their damaged lysosomes. The process, termed budding-type fission, or B-fission, allows a compromised lysosome to bud off…...
Anti-swelling biphasic conductive hydrogels enable 3D-printed implantable
18+ hour, 52+ min ago (608+ words) Hydrogels have long been considered one of the most promising material platforms for implantable bioelectronics. Soft, water-rich, and chemically similar to living tissue, they promise a gentle interface between electronics and biology. Yet despite decades of enthusiasm, hydrogel-based implants have…...
