Inside the nucleus of some atoms, protons appear to be doing very unexpected things. They are pairing up far more often than usual when they get extremely close to each other, and physicists don’t ...

Theory suggests that if physicists could cram just the right amount of stuff into a nucleus, the resulting element would hit a sweet spot. It could romp on the island of stability for days, months or ...

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff.--Carl Sagan Almost all ...

HEISENBERG has discussed the hypothesis that the nucleus of an atom is composed of neutrons and protons only, the neutron being regarded as a fundamental entity and not as a combination of an electron ...

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 ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...
