For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

What scientists long believed were knots in DNA may actually be persistent twists formed during nanopore analysis, revealing ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...

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 ...

Two new tools created at Gladstone Institutes allow scientists to study DNA at single-molecule resolution using fewer cells than previously required, with clear applications for cancer and many other ...

The newest DNA sequencing technology from Swiss multinational Roche doesn’t measure DNA directly but in fact analyzes a different polymer altogether. The technology is not yet available for sale, but ...

It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been ...

Although it also performs some functions in men, estrogen, the main female sex hormone, is involved in a myriad of processes, ...
