Nobel prize-winning physicist Steven Weinberg dies at 88

Physicist Steven Weinberg, who won the Nobel prize in 1979 with two other scientists for their separate contributions unlocking mysteries of tiny particles and their electromagnetic interaction, has died at 88, the University ...

Physicists net neutron star gold from measurement of lead

Nuclear physicists have made a new, highly accurate measurement of the thickness of the neutron "skin" that encompasses the lead nucleus in experiments conducted at the U.S. Department of Energy's Thomas Jefferson National ...

Nuclear physicists on the hunt for squeezed protons

While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights ...

Experiment to precisely measure electrons moves forward

A new probe of the humble electron may provide insight into the forces at work inside the heart of matter. Now, the MOLLER experiment at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility is one ...

The mystery of the neutron lifetime

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.

Real-time monitoring of proteins in the nuclear pore complex

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 ...
