Nine seconds. An eternity in some scientific experiments; an unimaginably small amount in the grand scheme of the universe. And just long enough to confound nuclear physicists studying the lifetime of the neutron.

It is important to mark the solemn 75th anniversary of the first and only use of atomic weapons against cities as not only a remembrance of a tragic past event, but as a reminder of an ever-present threat that we have failed ...

In human cells, the nucleus is enclosed by a structure called the nuclear pore complex (NPC). It acts as a 'gatekeeper' controlling the transport of molecules between the nucleus and the surrounding cytoplasm (the protein-containing ...

Scientists have long tried to experimentally demonstrate a certain symmetry property of the weak interaction—parity violation—in molecules. So far, this has not been possible. A new interdisciplinary effort led by a research ...

Scientists have been able to observe the universe and determine that about 80% of the its mass appears to be "dark matter," which exerts a gravitational pull but does not interact with light, and thus can't be seen with telescopes. ...

In an atomic nucleus, protons and neutrons, collectively called nucleons, are bound together by nuclear forces. These forces describe the interactions between nucleons, which cause them to occupy states grouped in shells, ...
