Nanoparticles get a magnetic handle

A long-sought goal of creating particles that can emit a colorful fluorescent glow in a biological environment, and that could be precisely manipulated into position within living cells, has been achieved by a team of researchers ...

Chemists develop faster, more efficient protein labeling

North Carolina State University researchers have created specially engineered mammalian cells to provide a new "chemical handle" which will enable researchers to label proteins of interest more efficiently, without disrupting ...

Proteins shine a brighter light on cellular processes

Scientists have designed a molecule which, in living cells, emits turquoise light three times brighter than possible until recently. This improves the sensitivity of cellular imaging, a technique where biological processes ...

Random walks on DNA

Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings, published in Science, present further insight into the coupling of chemical and mechanical ...
