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.
Plenty of teenagers say they want to study the brain. Very few get to do neuroscience research before college. University labs rarely take high school students, and the spots that do open tend to go to kids with a family…
Alcohol is one of the most commonly abused substances, and men are up to twice as likely to develop alcoholism as women. Until now, the underlying biology contributing to this difference in vulnerability has remained unclear. A new study published…
Why every neural network needs an activation function, explained with two simple equations. Deep networks stack layer after layer. But there's a catch hiding in that stack. Without one small ingredient, a hundred layers can do exactly what one layer…
By Ian Bickis, The Canadian Press Posted October 31, 2026 11:41 am. The clocks aren’t changing Sunday in the western half of the country, but that doesn’t mean changes aren’t coming as British Columbia, Alberta, Manitoba, northwestern Ontario and the Northwest Territories all…
What chemical processes in space could have created the building blocks of life is being researched by chemists at Ruhr-Universität Bochum (RUB) in Prof Dr Wolfram Sander's team. In their experiments, the scientists are simulating the conditions in space to…
[University of Cambridge]. Comets didn’t seed life on Earth after all, a new study suggests, potentially overturning a century-old idea. The theory that comets delivered the molecular building blocks for life on Earth is a long-standing one, since comets are…

Astrobiology (Journal) The origin of biological homochirality remains a central enigma in astrobiology. The emergence of a homochiral world necessitates two key processes: initial symmetry breaking and subsequent chiral selection […] Astrobiology (Journal) The origin of biological homochirality remains a central…
Adult astrocytes stretched, divided, and moved new nuclei into damaged brain regions during a temporary repair state. (CREDIT: Shutterstock) A damaged patch of adult brain tissue can trigger nearby support cells to stretch, divide, and send newly formed nuclei into…
Scientists are getting astonishingly good at extracting ancient human DNA from mere dirt and dust, even when there are no physical remains left… No bones, no teeth, no fossils. A small scoop of sediment from a cave in Spain has…
