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.

New Computational Framework Tracks Cell Migration Across Space and Time
4+ hour, 5+ min ago (879+ words) Scientists have unveiled a new computational framework that brings together two of the most powerful technologies in modern biology—single-cell RNA sequencing and spatial transcriptomics—to reconstruct how populations of cells redistribute and change state across time within living tissues....
Systemic Humoral Immunity in the Partially Migratory Bat Leptonycteris
4+ hour, 22+ min ago (90+ words) {“title”:”Gut Microbes Shape Bat Immunity Differently in Males and Females”,”excerpt”:”A new study of the lesser long-nosed bat reveals that gut bacterial communities are linked to systemic humoral immunity in patterns that differ sharply between males and migrating…...
Genetic Suppressors Rescue Tubulin Mutations and Restore Microtubule
4+ hour, 32+ min ago (757+ words) Microtubules are among the most essential structures in any cell, hollow filaments built from α- and β-tubulin dimers that provide mechanical scaffolding, act as railways for intracellular transport, and form the spindle apparatus that segregates chromosomes during division. When the…...
Chemists forge chiral piperidine mimics in a single asymmetric leap
4+ hour, 33+ min ago (904+ words) Medicinal chemists have long chased a deceptively simple goal: build drug candidates that are less flat, more three-dimensional, and more likely to succeed in the clinic....
Bird Guts Are a Dead End for Stick Insect Eggs, Digestion Experiments
8+ hour, 25+ min ago (793+ words) Stick and leaf insects are among the most accomplished masters of disguise in the animal kingdom, but their most remarkable imitation may be the one nobody watches happen. The eggs of many phasmid species look uncannily like plant seeds, complete…...
Silent fMRI Framework Captures Brain-Wide Networks in Behaving Mice
9+ hour, 15+ min ago (759+ words) For decades, functional magnetic resonance imaging has offered scientists an unmatched window into the human brain, revealing whole-brain networks at work without a single incision. Yet when researchers attempt to bring that same power to bear on the smallest and…...
Fibroblasts With a Stem Cell Marker Help Skin Adapt to Mechanical Stress
9+ hour, 46+ min ago (819+ words) Skin is the body’s first line of defense and its most resilient mechanical shield, stretched, compressed, and sheared thousands of times a day without failing. Yet the cellular machinery that allows this outer organ to continuously remodel itself under physical…...
One Centromere Gene, Two Genomic Homes: Fly Study Reveals Surprising
10+ hour, 18+ min ago (820+ words) Centromeres are among the most essential structures in the cell, yet they remain among the least intuitively understood features of the eukaryotic genome. These specialized chromosomal regions serve as the attachment points for spindle fibers during cell division, ensuring that…...
A genomic catalog of Earth’s bacterial and archaeal symbionts
10+ hour, 22+ min ago (918+ words) The assembly of a genomic catalog devoted specifically to bacterial and archaeal symbionts represents a meaningful shift in how large-scale microbiome resources are organized....
Key Gene Controlling Stem Diameter in Flax Identified by Genome-Wide Study
10+ hour, 22+ min ago (805+ words) Lodging, the structural failure of crop stems that bend or collapse under their own weight or under the pressure of wind and rain, remains one of the most persistent threats to agricultural productivity worldwide....
