Quarks in the looking glass
A recent experiment carried out at DOE's Jefferson Lab has determined how much of the mirror-symmetry breaking in the electron-quark interaction originates from quarks' spin preference in the weak interaction five times more precisely than a previous measurement. The result has also set new limits, in a way complementary to high-energy colliders such as the Large Hadron Collider at CERN, for the energies that researchers would need to access physics beyond the Standard Model.

Newly invented shielding for stopping neutrons cold
When faced with the challenge of protecting sensitive scientific equipment and computers from radiation, engineers at the US Department of Energy's Thomas Jefferson National Accelerator Facility decided to take matters into their own hands. They came up with three innovative products that could soon find their way to nuclear power plants, particle accelerators and other radiation-generating devices around the world.
