A powerful laser is directed into a jet of gas, forming a bright plasma that generates ultraviolet light. As this light interacts with the remaining gas in the vacuum chamber, it creates a visible white line. This method allows scientists to accurately measure the energy required to excite the thorium-229 nucleus, which is crucial for developing a future nuclear clock.

Electrons are made up of a negative electrical charge, and scientists at JILA have been trying to measure how evenly that charge is spread between the north and south pole of the electron. Any unevenness would indicate that the electron is not perfectly round, and that would be evidence of an asymmetry in the early universe that led to the existence of matter. The Cornell Group at JILA studied how the electrons in molecules behaved as they adjusted the magnetic field around them to look for any shift in the electrons. Credit: JILA/Steven Burrows

Copper “headphones” boost the sensitivity of NIST’s atomic radio receiver, which is composed of a gas of cesium atoms prepared in a special state inside the glass container. When an antenna located above the setup sends down a radio signal, the headphones boost the strength of the received signal a hundredfold.
