CryoEM study captures opioid signaling in the act

Opioid drugs like morphine and fentanyl are a mainstay of modern pain medicine. But they also cause constipation, are highly addictive, and can lead to fatal respiratory failure if taken at too high a dose. Scientists have ...

New beacons light up the interior

LMU's Ralf Jungmann develops modes of microscopy that can resolve cellular structures with dimensions on the order of nanometers. He has now succeeded in imaging actin networks in cells in greater detail than before.

Remote control of transport through nanopores

In our bodies, the transfer of genetic information, viral infections and protein trafficking, as well as the synthesis and the degradation of biomolecules, are all phenomena that require the transport of molecules through ...

Newly discovered protein operated in earliest organisms

Life on Earth depends on photosynthetic carbon dioxide (CO2) fixation to form organic carbon. Plants take atmospheric CO2 and transform it into organic molecules such as glucose. This process evolved in cyanobacteria and ...

Mechanical force controls the speed of protein synthesis

As cells create proteins, the proteins modulate synthesis speed by exerting a mechanical force on the molecular machine that makes them, according to a team of scientists who used a combination of computational and experimental ...
