The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

Researchers from the University of Technology Sydney (UTS) and the University of Manchester in the United Kingdom have ...

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...

Researchers have developed a new approach in optical atomic clocks that brings forth a major goal in science: the redefinition of a second. The fundamental unit of time could soon be based on ...

For this purpose, this new ion crystal clock was compared with other optical clocks and a new accuracy record was achieved. The PTB researchers report their in Physical Review Letters. An undisturbed ...

One in particular caught our eye, in a write-up from Steve Wientz, that is described as an atomic outboard motor. It started as an outgrowth from General Electric’s 1950s work on airborne ...

Neurological disorders are becoming an increasingly significant societal burden, highlighting the critical need for improved ...

New atomic clocks are more accurate than those used to define the second, ... Ion clocks and optical lattice clocks have been trading the accuracy record back and forth for the past two decades.

The Navy has hopes of harnessing atomic power for ship propulsion. Announcement of the signing of a $103,000 contract—to study the possibilities at St. Louis’ Washington University—battened ...

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 ...

Our collection of antimatter has just gotten heavier, as researchers have logged the heaviest antimatter version of an atomic nucleus yet, called antihyperhydrogen-4.
