Physicists at JILA have created the first "frequency comb" in the extreme, ultraviolet band of the spectrum--high-energy light less than 100 nanometers in wavelength. Laser-generated frequency combs are the most accurate method available for precisely measuring frequencies, or colors, of light. The new tool can aid in the development of nuclear clocks based on ticks in the nuclei of atoms, and measurements of previously unexplored behavior in atoms and molecules.Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2023 budget of $9.5 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
