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.

Scientists Are Turning to A.I. in an Ambitious New Effort to Resurrect the Dodo from Extinction
12+ hour, 53+ min ago (953+ words) Scientists say they are one step closer to reviving the long-extinct dodo, thanks to new advancements in artificial intelligence, genetic engineering, and other technologies. The work, undertaken by researchers with Texas-based Colossal Biosciences, is leveraging genetic engineering and advanced reproductive…...
New AI Breakthrough Brings Extinct Dodo Bird Closer to Revival
6+ hour, 21+ min ago (420+ words) A U.S. biotechnology company has identified about 2,300 potential genetic targets with the help of AI that could help bring back the extinct dodo, a flightless bird that disappeared more than 300 years ago. The discovery marks another step in efforts to recreate…...
Plants use molecular ‘measuring tape’ to tell friend from foe
8+ hour, 23+ min ago (638+ words) Light microscopy image of crystallised CHIP13 protein. (Kira Gysel via SWNS) Plants use a molecular “measuring tape” to tell friend from foe, reveals new research. It enables them to distinguish harmful fungi from beneficial partners, say Danish scientists. They explained that…...
Reston virus genomes hint at decades of undetected circulation
6+ hour, 18+ min ago (666+ words) Reston virus, the only member of the ebolavirus genus known to circulate in Asia rather than Africa, has long presented an epidemiological paradox....
Apple Gene MhLHCA2 Helps Plants Survive Iron-Starved Soils, Study Finds
18+ hour, 52+ 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
1+ day, 53+ 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
1+ day, 11+ 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, 13+ hour 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, 13+ hour 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, 16+ 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…...
