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.

These Beautiful Flowers Can Paralyze You, but Their Chemistry Could Save Lives
3+ hour, 18+ min ago (836+ words) Researchers take the first steps toward recreating powerful chemicals derived from plants in the laboratory. Wolfsbane and larkspur can cause neurotoxicity and paralysis at extremely low doses, yet their chemistry has also been used against pain, malaria, cancer, and pests....
HMGA1 Promotes Bone-Like Transformation of Vascular Muscle Cells in Kidney
24+ min ago (501+ words) Chronic kidney disease is often described as a disorder of filtration, but its consequences extend far beyond the kidneys. One of its most dangerous complications is vascular calcification, a process in which the walls of arteries gradually accumulate mineral deposits…...
New study reveals aging unfolds at different rates across individual cells
3+ hour, 6+ min ago (435+ words) Aging may be far less synchronized than scientists have traditionally assumed. A new study published in Nature Communications reports that cells of the same chronological age can follow dramatically different biological aging trajectories, even when they are located beside one…...
Smithsonian scientists untangle Hawaiian honeycreeper evolutionary family
5+ hour, 46+ min ago (435+ words) Smithsonian researchers have reconstructed the most comprehensive evolutionary map yet of Hawaii’s honeycreepers, a spectacular group of birds whose rapid diversification produced more than 60 species from a single ancestral population. The study, published in the Proceedings of the National Academy…...
Scientists Reveal How Centromeres and Inner Kinetochores Work
6+ hour, 35+ min ago (468+ words) A new review in Nature Reviews Molecular Cell Biology is bringing the hidden architecture of chromosome inheritance into sharper focus, examining how centromeres and inner kinetochores work together to guide chromosomes through cell division. The study, authored by R. R. Brown, P. J. Huis…...
How the Outer Kinetochore Is Built and Functions
11+ hour, 53+ min ago (95+ words) The molecular machine that decides when a chromosome is ready to move during cell division is coming into sharper focus. In a new Review published in Nature Reviews Molecular Cell Biology, researchers examine how the outer kinetochore coordinates microtubule attachment,…...
Child dies after experimental genome editing in China | PET
21+ hour, 16+ min ago (364+ words) A six-year-old girl has died following an experimental genome editing treatment, prompting an investigation into the clinical trial by the university involved. The trial was led by neuroscientist Dr Zilong Qiu, and is the first known use of a genome…...
VIM2/4 Deletion and Truncated CMT2/FBX5 Drive DNA Methylation Changes After
15+ hour, 42+ min ago (502+ words) A plant’s first steps into a new habitat can leave a molecular footprint far deeper than scientists once imagined....
Cloning Has Advanced from Dolly to Medical Research and Gene Editing
21+ hour, 40+ min ago (182+ words) From frogs and sheep to monkeys and endangered species, each milestone has raised new scientific possibilities—and difficult questions about what should come next. Cloning is the process of creating an exact copy of an object using genetic material. The…...
Scientists Identify Seven Previously Unknown Frog Species in Madagascar
22+ hour, 11+ min ago (416+ words) An international team of scientists has described seven new species of diamond frogs from Madagascar, revealing that the island’s secretive genus Rhombophryne contains far more evolutionary diversity than previously recognised....
