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.
New research identifies cellular processes that appear to supercharge both growth and shrinkage of telomeres—the chemical “caps” on chromosomes associated with aging. The work, which focused on two enzymes in yeast, could lead to new insights on stopping runaway cellular growth in cancer tumors and the treatment of premature aging…
Research links lysosomal calcium and cAMP activity to regulation of heart rate and finds related cellular changes in atrial fibrillation Illustration of a human cell structure They found that lysosomes act as signalling centres…
Scientists have described Diploderma gulaense, a new dragon lizard species from a Tibetan river valley, using mitochondrial DNA and morphology.
Last verified: 5 November 2026. A vault is a large, hollow, barrel-shaped protein shell found across most of the eukaryotic tree, from slime moulds to humans. Leonard Rome and Nancy Kedersha discovered them in 1986, and the…
Controlling gene expression is essential to growth, development, and sustained life. This requires regulating the spacial, temporal, and developmental expression of genes in a wide diversity of cell types. Our research program…
Research with mice has identified some of the key steps that peripheral nerves—those in the arms and legs—take as they regenerate. Neurons in the brain and spinal cord don’t grow back after injury, unlike those in the rest of the body. Cut your finger, and you’ll probably be back to…
You can take the protein out of the oligodendrocyte, but you can’t take the oligodendrocyte out of the protein. In the May 9 Nature, researchers led by Virginia Lee at the University of Pennsylvania, ... You can take the protein…
November 7, 2026 report by Andrew Zinin, Medical Xpress The targeted cells lie in the hippocampus, a brain region important for learning and memory. When researchers quieted these brain cells, it impaired the animals' ability to…
Jacquet found that when exposed to fluorescently labeled aggregates of Aβ, primary microglia quickly rearranged their plasma membranes to form an invagination surrounding each aggregate. Digestive Hug. Exposure to Aβ aggregates…
Researchers have created a computational model capable of predicting whether or not organisms have the ability to 'eat' other cells through a process known as phagocytosis. The model may be a useful tool for large-scale microbe surveys and provides valuable insight into the evolution of complex life on Earth, challenging…
Scientists have uncovered new details about how bacteria share genes, including those that drive antimicrobial resistance (AMR), a growing global health threat. The findings come from researchers at the John Innes Centre, who…
