High-contrast imaging for cancer therapy with protons

Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology—OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have combined magnetic resonance imaging (MRI) with a proton beam, thus demonstrating ...

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 ...

Producing four top quarks at once to explore the unknown

For several decades, particle physicists have been trying to better understand nature at the smallest distances by colliding particles at the highest energies. While the Standard Model of particle physics has successfully ...

The Large Hadron Collider prepares for the future

The Large Hadron Collider (LHC) is stopping proton collisions for five days this week to undergo numerous tests. Accelerator specialists need to test the LHC when it is not in production mode and there are only several weeks ...

Hunting for dark quarks

Quarks are the smallest particles that we know of. In fact, according to the Standard Model of particle physics, which describes all known particles and their interactions, quarks should be infinitely small. If that's not ...
