Growing inside each of us is a cellular family tree. Every one of the 37 trillion cells in our body is generated from another cell, going all the way back to a single fertilized egg. Much like we can draw a family tree tracking ...
A new engineered gene-editing system, proven in bacteria and showing promise for use in plants, animals and humans, addresses some limitations of current gene-editing tools, with the goal of improving their use in research, ...
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 bad apple doesn't always ruin the bunch. In fact, it might make the bunch a little stronger. A new study published in Horticulture Research by Ben Mansfeld, an assistant professor of biology in Arts & Sciences at Washington ...
Evolution is driven by changes in DNA that sometimes promote adaptation, altering traits like disease resistance or reproduction. Often, these changes are minuscule, modifying a single letter in the DNA code—somewhat like ...
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 ...
Two new studies from Johns Hopkins University are providing scientists with an unprecedented view of how human cells repair one of the most dangerous forms of genetic damage: a break that severs both strands of the DNA double ...
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 ...
Research scientist Ashish Rajurkar kneels in the dirt, lifting a large clod of soil tangled around a soybean plant. He knocks away pieces of earth from the plant's roots, which slope straight down instead of out to the side ...
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, ...
