Scientists have long sought to understand what makes us human. From the standpoint of DNA sequences, we have a lot in common with our closest evolutionary relative, the chimpanzee. The regulation of ...

What’s the story behind DNA melting temperature analysis? UV-Visible absorption spectroscopy can be used to assess the characteristics of deoxyribonucleic acid (DNA), a naturally occurring polymer ...

Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

Given that phages are able to destroy bacteria, they are of particular interest to science. Basic researchers are especially interested in the tube used by phages to implant their DNA into bacteria.

Scientists at the University of Stuttgart have succeeded in controlling the structure and function of biological membranes with the help of "DNA origami". The system they developed may facilitate the ...

A University of Iowa-led study has revealed the unexpected structure adopted by the DNA repair protein RAD52 as it binds and protects replicating DNA in dividing cells. This new structural and ...

James Dewey Watson, a molecular biologist whose work helped decode the structure of DNA, died on November 6, 2025, at a hospice in East Northport, N.Y. He was 97 years old. Watson was best known for ...

For James Watson, DNA was everything — not just his life's work, but the secret of life itself. Over his long and storied career, Watson arguably did more than any other scientist to transform a ...
