Snapshots of the hydrogen jet Shadowgraphs at the time of impact of the high-intensity laser pulse on the jet of hydrogen. A weaker light pulse sent in advance ...

Protons, the positively charged particles that help build every atom in our bodies, are starting to look less like classical ...

When you get an MRI scan, the machine exploits a phenomenon called nuclear magnetic resonance (NMR). Certain kinds of atomic nuclei—including those of the hydrogen atoms in a water molecule—can be ...

DEEP in the heart of every atom lurk protons, tiny particles from which the chemical elements were forged, first in the searing heat of the big bang and then in the nuclear furnaces of stars. The ...
