Geneva, 8 November 2010. Four days is all it took for the LHC operations team at CERN* to complete the transition from protons to lead ions in the LHC. After extracting the final proton beam of 2010 on 4 November, commissioning the lead-ion beam w…
Biophysicists in Bochum have discovered a diode for protons: just like the electronic component determines the direction of flow of electric current, the “proton diode” ensures that protons can only pass through a cell membrane in one direction….
When Gerald A. Miller first saw the experimental results from the Thomas Jefferson National Accelerator Facility, he was pretty sure they couldn’t be right. If they were, it meant that some long-held notions about the proton, a primary building block of atoms, were wrong. But in time, the findings proved to be right, and led physicists to the conclusion that protons aren’t always spherically shaped, like a basketball.
