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.

Green Nanoparticles May Carry Hidden Plant Chemistry That Shapes Stress
4+ hour, 48+ min ago (94+ words) Green nanotechnology has become one of the most fashionable corners of plant science, promising fertilizers, pesticides, and stress-protective agents built from nothing more exotic than plant extracts and metal salts. The recipe sounds almost too simple: mix a leaf or…...
Tiny Genetic Regulators Go Awry in Rare DNA Repair Disorder, Study Finds
8+ hour, 45+ min ago (55+ words) Ataxia-telangiectasia, or A-T, is one of the most devastating genome-instability disorders known to medicine. Children born with the condition face progressive degeneration of the cerebellum, the brain region that coordinates movement, alongside visible dilation of small blood vessels in the…...
Thirty Years of Teak Data Reveal Which Clones Deserve to Stay
8+ hour, 45+ min ago (115+ words) In the quiet research plots of the Tropical Forest Research Institute in Jabalpur, India, a living experiment has been quietly maturing for more than three decades. Planted in the early 1990s, a clonal trial of teak (Tectona grandis) containing genetic material…...
New aligner brings recombination-aware mapping of long reads to pangenome
10+ hour, 11+ min ago (693+ words) For years, genomicists have relied on a single linear reference genome as the backbone of read mapping, a convention that quietly discards much of the richness of human genetic diversity. The rise of graph pangenomes has begun to change that....
Viral Barcodes Reveal the Hidden Family Tree of the Newborn Mouse Brain
12+ hour, 6+ min ago (649+ words) Every mammalian brain begins as a modest pool of progenitor cells, yet it ends up containing hundreds of molecularly distinct cell types. How that transformation unfolds—who descends from whom, and where each descendant ultimately settles—has remained one of…...
Cell-by-cell maps reveal hidden complexity of genomic imprinting in maize
12+ hour, 56+ min ago (571+ words) Genomic imprinting, the curious phenomenon in which a gene is expressed depending on which parent it was inherited from, was first discovered in maize nearly a century ago....
Chromosome Chaos: How Aneuploid Rapeseed Keeps Pollen Alive Despite Meiotic
13+ hour, 13+ min ago (664+ words) When plants end up with the wrong number of chromosomes, the consequences are usually dire. Cells starved of, or overloaded with, gene copies struggle to divide, grow, and reproduce, and in animals the result is often lethal. Yet in the…...
Greenhouse Microbes That Unlock Locked Phosphorus Emerge From Massive
14+ hour, 31+ min ago (692+ words) In the humid, carefully calibrated world of greenhouse production, one of the most stubborn problems is invisible to the naked eye. Phosphorus, the macronutrient that drives root development, vegetative growth, and flower initiation, has a habit of vanishing from the…...
Rare Spinal Cancer With Liver Spread Documented in a Pet Corn Snake
14+ hour, 46+ min ago (68+ words) A 14-year-old corn snake has become the subject of a remarkable veterinary case report that offers one of the most detailed looks yet at a rare and aggressive cancer in reptiles. Writing in the journal Veterinary Oncology, researchers at the…...
Neural Networks Spontaneously Split Into Context and Sensory Specialists
14+ hour, 46+ min ago (55+ words) How does the brain know that the same snake deserves calm curiosity at the zoo and a hasty retreat on a wilderness trail? This everyday feat, known as context-dependent processing, allows primates to respond flexibly to identical stimuli depending on…...
