The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors, ...

DNA is often called the blueprint of life, but what does that really mean? Elizabeth Worthey, Ph.D., associate professor, Department of Genetics in the Heersink School of Medicine, explains everything ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...

Alphabet Inc.’s Google DeepMind today introduced AlphaGenome, a new artificial intelligence tool that can comprehensively predict how mutations or variants in human DNA sequences impact gene ...

The Age of AI will rely on massive volumes of data that can be easily stored and retrieved—and bioscience may have an ingenious solution. A scientist examines a DNA (deoxyribonucleic acid) profile on ...

DNA isn't just a long string of genetic code, but an intricate 3D structure folded inside each cell. That means the tools used to study DNA need to be just as sophisticated—able to read not only the ...

The world's oldest DNA comes from a 2.4 million-year-old ecosystem in Greenland. Will scientists eventually sequence even older DNA? When you purchase through links on our site, we may earn an ...

Scientists found that DNA’s phosphate groups can direct chemical reactions to make the correct mirror-image form of drug molecules. This breakthrough simplifies chiral drug production, reducing waste ...

Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published March 3 as two papers in ...
