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.

Cellular Life Process Captured Live for First Time
23+ min ago (221+ words) Mirage News All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA, the molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic RNA polymerase II,…...
Researchers design a novel, stable human growth factor
7+ hour, 55+ min ago (630+ words) Scientists at the University of Arkansas have developed a more stable and biologically active form of human fibroblast growth factor 1, a signaling protein with important roles in cell growth, tissue repair and metabolism....
Study uncovers overlooked DNA mutation pattern linked to colorectal cancer
11+ hour, 49+ min ago (618+ words) Researchers at the University of California San Diego and collaborating institutions have identified and validated a previously overlooked pattern of DNA mutations in colorectal cancer, revealing a recurring genomic feature that may reflect changes in the way tumor cells replicate…...

Proteomics identifies two reproducible sepsis-associated kidney injury
16+ hour, 17+ min ago (529+ words) A new study published in Nature Communications reports that sepsis-associated acute kidney injury, one of the most dangerous complications of severe infection, is not a single biological condition. Using plasma proteomics, an international research team led by Marc Legrand, Huy…...
Viral Enzyme Disables Bacterial Defenses for Phages
1+ day, 1+ hour ago (485+ words) Scientists have found how phages, viruses that infect bacteria, orchestrate an explosion of protein modifications inside host cells that helps them evade the bacteria's immune systems As antimicrobial resistance grows around the world, novel therapies to counter it become increasingly…...
How Multi-Omics and AI Could Reveal Why Blood Stem Cells Age
1+ day, 3+ hour ago (625+ words) Hematopoietic stem cells, the rare self-renewing cells that continually replenish blood and immune populations, do not simply “wear out” with age. They undergo a complex biological transformation that reshapes how they read DNA, respond to stress, interact with their surroundings…...
How Circadian Rhythms Shape Sarcopenia and the Aging Muscle
1+ day, 7+ hour ago (620+ words) Aging muscle may be governed not only by exercise, nutrition, and hormones, but also by the biological clock ticking inside every muscle cell....
Male Mice Cloned into Both Sexes, Reproduce
1+ day, 14+ hour ago (350+ words) A cloning technology has been developed that creates both male and female mice using only the genetic information of male mice. The resulting females and males successfully mated and produced offspring. Experts suggest this method could help revive endangered species…...
