Common wisdom has it that protons only travel between molecules via hydrogen bonds: no hydrogen bonds, no proton transfer. Scientists investigating molecular components of RNA were surprised to find ...

Measurement in ordinary hydrogen agrees with a surprising 2010 result on the element's exotic cousin — but gives a smaller value than virtually every other experiment. The proton might truly be ...

How big is a proton? Unlike an electron or neutrino, which are fundamental particles that behave like points, a proton is a messy collection of quarks, gluons, and virtual particles that occupies what ...

Graphene, impermeable to all gases and liquids, can easily allow protons to pass through it researchers have found. Published in the journal Nature, the discovery could revolutionise fuel cells and ...

You’re in good company: This question also stumped the physicists who first tried to understand nuclear fusion in stars. In a star’s core, all atomic nuclei have been separated from their electrons, ...
