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.

50mn tonnes of sugar from deep space delivered a sweet start to life on Earth
10+ hour, 4+ min ago (172+ words) Sugar is a crucial building block of life, and Earth received nearly 50 million tonnes of it over four billion years ago. Interstellar dust is full of it, a study has found, and could have possibly sprinkled it on other parts…...
Osteoclasts Trigger DCC Loop Causing Chronic Low Back Pain in Mice
4+ hour, 59+ min ago (217+ words) Mechanistically, osteoclast-derived signals enhance DCC expression and activation in excitatory dorsal horn neurons, which in turn augment synaptic transmission and facilitate central sensitization—key hallmarks of nociplastic pain. This feedback loop was shown to maintain a sustained state of dorsal…...
