Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future ...

The time is nigh for nuclear clocks. In a first, scientists have used a tabletop laser to bump an atomic nucleus into a higher energy state. It’s a feat that sets scientists on a path toward creating ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...

Atomic clocks are the most accurate timekeepers we have, losing only seconds across billions of years. But apparently that’s not accurate enough – nuclear clocks could steal their thunder, speeding up ...

Photoionization, the process by which an incident photon ejects an electron from an atom, lies at the heart of many atomic physics studies. Coupled with cross section measurements – which quantify the ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce ...

Physicists are getting closer to creating a long-sought ‘nuclear clock’. This device would keep time by measuring energy ...

Scientists have demonstrated a new way to use high-energy particle smashups at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy (DOE) Office of Science user facility for nuclear ...

Years before Robert Oppenheimer led the Los Alamos lab that developed the first nuclear weapons, physicists in D.C. thrust the world into the atomic age — inside a narrow, zigzagging tunnel running ...

1 The Arts and Humanities (AH) and Social Sciences (SS) perspectives are subsets of the Breadth of Knowledge (BOK) requirements in the Core Curriculum. No more than two BOK courses can be taken with ...

From outer space to the human brain, Tufts University’s research labs explore various fields of science to uncover new ...
