How do bacteria adapt when resources run low? ISTA researchers have found that, under starvation stress, E. coli can use bacteriophages and CRISPR-Cas immunity to transfer and incorporate DNA, accelerating genetic reshuffling. ...
A new tool to mutate bacteriophages—viruses that infect bacteria—provides a "big leap" forward in our understanding of how they function and our ability to harness their full potential.
U.S. artificial intelligence startup Anthropic on Wednesday unveiled the first discovery from its molecular biology lab, a previously unknown enzyme system spotted by its Claude model and touted by the company as proof that ...
Sejong University researchers have developed a high-quality soybean with improved oxidative stability, reduced saturated fat and increased seed fatty acid content. The research team led by Hyun Uk Kim, a professor in the ...
The ability of cells to move and change position is essential for various processes in our bodies. Immune cells move to sites of action, epithelial cells migrate during wound closure, and neurons extend their axons for signal ...
CRISPR may be a powerful technology for gene editing, but the system existed in bacteria long before scientists began using it. For billions of years, CRISPR has acted as a natural immune system in bacteria and other microbes, ...
Cysteine is one of the main building blocks that cells use to make proteins. But this amino acid is a double-edged sword—too much cysteine is toxic to the cell. Cells therefore keep free cysteine levels to a minimum, converting ...
Understanding gene regulation may be key to interpreting human disease genetics. Genes are regulated in part by stretches of DNA called enhancers, which define when, where and how strongly each gene is turned on. Mapping ...
A study by researchers at Columbia University Vagelos College of Physicians and Surgeons has found that new cutting-edge techniques can accurately edit genes in human embryos—giving scientists indispensable tools for understanding ...
Editing a plant's genes is only half the battle. Before a new, improved trait can ever reach a farmer's field, scientists must be able to grow a whole plant from just a few edited cells—a process that can be slow, unreliable ...
