The helix, of DNA fame, may have arisen with startling ease

Trying to explain how DNA and RNA evolved to form such neat spirals has been a notorious enigma in science. But a new study suggests the rotation may have occurred with ease billions of years ago when RNA's chemical ancestors ...

Image: Space chips etched in silicon

Multiple integrated circuits destined to serve as the brains of Europe's future space missions are etched together onto single pieces of silicon.

Fully identified—the pathway of protons

In their catalytic center, hydrogenases manufacture molecular hydrogen (H2) from two protons and two electrons. They extract the protons required for this process from the surrounding water and transfer them – via a transport ...

Disrupting communication in infectious bacteria

Chemists in Konstanz have inhibited the biosynthesis of a bacterial signal and, as a result, blocked the infectious properties of Pseudomonas aeruginosa, the most common germ found in health care facilities.

Atomic view of nature's amazing molecular machines at work

Researchers from the MPSD's Department of Atomically Resolved Dynamics at the Center for Free-Electron Laser Science, the Centre for Ultrafast Imaging (all in Hamburg), the University of Toronto in Canada and the ETH in Zurich, ...
