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.

Apple Gene MhLHCA2 Helps Plants Survive Iron-Starved Soils, Study Finds
5+ hour, 57+ min ago (379+ words) Researchers at Gansu Agricultural University report that the photosystem I gene MhLHCA2 helps apple tissue withstand iron deficiency by sustaining photosynthetic performance, antioxidant defenses and iron acquisition processes. Iron is one of those nutrients that plants cannot live without, yet in…...
Scientists Reverse Aging in Cells and Mice With a Single Gene
11+ hour, 58+ min ago (673+ words) Harvard-led researchers developed a transcriptomic aging clock to screen rejuvenation genes and found that over-expressing the RNA splicing factor SRSF1 reverses multiple hallmarks of aging in human cells and extends median lifespan in mice by 14 percent....
Barley’s Hidden Grain Hierarchy: Genes That Decide Which Seeds Win
11+ hour, 16+ min ago (647+ words) A genome-wide association study of 334 barley accessions combined with spatiotemporal transcriptomics reveals that asymmetric carbon metabolism during grain filling drives the positional size differences among grains on a barley spike....
Scientists Capture How Powerful DNA-Engineering Enzymes Control the Direction of Genetic Changes
1+ day, 18+ min ago (222+ words) Newswise — Bacteriophages, or viruses that infect bacteria, have a fiendishly simple purpose in life: attach to a bacterial cell, inject their DNA, and then use the host’s genetic machinery to reproduce. In doing so, they may have evolved some of…...
CRISPR-Based Test Improves Detection of HIV and Other RNA Viruses
1+ day, 42+ min ago (435+ words) Researchers at Rice University have engineered a CRISPR enzyme that can detect RNA with 100 times greater sensitivity than its original version. The findings, published in Cell Chemical Biology, could also support the development of diagnostic tests for HIV and other…...
Genome Editing Moves Personalized Therapy Closer to Reality
1+ day, 3+ hour ago (286+ words) To address these barriers, researchers have been testing in situ administration — direct delivery into specific brain regions — in addition to developing advanced carriers such as lipid nanoparticles and next-generation viral vectors coated with high-affinity peptides. Lipid nanoparticles, for example, were…...
PrimeStack: New Gene-Stacking Tool Writes Large DNA Cargos Into Rice Genomes at Precise Sites
1+ day, 13+ hour ago (75+ words) Bioengineer.org Subject of Research: Site-specific integration of large multigene DNA cargos into plant genomes using combined prime editing and serine integrase technology in rice Article Title: PrimeStack editors enable efficient and site-specific integration of large multigene cargos in plants…...
Newly discovered antiviral system in bacteria is ‘strangest of its kind’
1+ day, 23+ hour ago (835+ words) The complex Rube Goldberg-like molecular machinery could inspire novel technology to study and treat disease image: Gladstone scientists, including Karen Zhang, uncovered a counterintuitive class of bacterial defense systems, known as type VI retrons, that can be adapted to engineer…...
How Insertion Sequence-Mediated Gene Amplification Helps Acinetobacter baumannii Adapt to the Host
2+ day, 3+ hour ago (277+ words) | Newswise Newswise How Insertion Sequence-Mediated Gene Amplification Helps Acinetobacter baumannii Adapt to the Host Increased crp-osmC copy number enhances competitive fitness, host colonization, and serum survival in Acinetobacter baumannii. Newswise — This study was led by Yuqin Song and Jie Feng…...
Scientists Uncover Hidden Protein Driver Behind Scarring Kidney Disease
2+ day, 3+ hour ago (658+ words) New research reveals that the protein Annexin A1 drives kidney fibrosis by activating YAP signaling and suppressing autophagy in renal fibroblasts, suggesting a promising therapeutic target for chronic kidney disease....
