Seeing antibiotics in action inside a pathogenic bacterium

Every living cell relies on proteins in order to function and the process of protein synthesis—translation—is critical for survival. Bacteria are no exception, with molecular machines involved in translation being one ...

World record resolution in cryo electron microscopy

Holger Stark from the Max Planck Institute for Biophysical Chemistry in Göttingen and his team have broken a crucial resolution barrier in cryo electron microscopy. For the first time, his group succeeded in observing individual ...

Physicists use oscillations of atoms to control a phase transition

The goal of 'femtochemistry' is to film and control chemical reactions with short flashes of light. Using consecutive laser pulses, atomic bonds can be excited precisely and broken as desired. So far, this has been demonstrated ...

How the coronavirus multiplies its genetic material

When someone becomes infected with the novel coronavirus SARS-CoV-2, the pathogen proliferates rapidly in the cells of the infected person. To do so, the virus has to multiply its genetic material, which consists of a single ...

Instant messaging in proteins discovered

Proteins are essential for every living cell and responsible for many fundamental processes. In particular, they are required as bio-catalysts in metabolism and for signaling inside the cell and between cells. Many diseases ...

How DNA is read and copied

Two scientists at the Johns Hopkins University School of Medicine have unraveled aspects of how DNA organizes and preserves genetic information. Newly published research by Cynthia Wolberger, Ph.D., and James Berger, Ph.D., ...
