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.

Optical strain and spectral-spatial networks decode micro-expressions
13+ min ago (61+ words) Micro-expressions are the fleeting, involuntary facial movements that betray a person’s true emotional state in a fraction of a second, often lasting less than half a second and appearing on the face before any conscious attempt at suppression can take…...
Machine learning verifies Lycii Fructus origins via metabolite and element
2+ hour, 55+ min ago (59+ words) In the arid highlands of northwestern China, the small red berry known as gouqi, or Lycii Fructus, has been prized for centuries as both a food and a traditional medicine, believed to support liver and kidney health, improve eyesight, and…...
Formononetin fights cellular aging via FOS-driven pathway
7+ hour, 24+ 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....

Inflammation of brain blood vessels drives cortical superficial siderosis
9+ hour, 31+ 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
12+ hour, 28+ 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
17+ hour, 23+ 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
17+ hour, 25+ 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
21+ hour, 6+ 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,…...
