Part of Operation Upshot-Knothole, was a 15-kiloton test fired from a 280-mm cannon on May 25, 1953 at the Nevada Proving Grounds. 72 years ago the U.S. Army carried out its first and only nuclear ...

THE successful manner in which the single-particle model of the atomic nucleus has accounted for many nuclear properties is well known to those who follow developments in nuclear physics. This model, ...

From atomic clocks to secure communication to quantum computers: these developments are based on the increasingly better control of the quantum behaviour of electrons in atomic shells with the help of ...

The extremely precise control of nuclear excitations opens up possibilities of ultra-precise atomic clocks and powerful nuclear batteries. From atomic clocks to secure communication to quantum ...

How big is an atomic bomb? It took a B-29 to carry the first one, dropped on Hiroshima, which may have weighed more than 10,000 Ibs. The Army’s announcement last week that it will abandon its ...

Key Point: The Soviets lost interest in launching nuclear weapons from tanks, but their usefulness has not disappeared. In the 1950s and 1960s when tactical nuclear weapons were expected to rule the ...

For the first time scientists can see how the shells of tiny marine organisms grow atom-by-atom, a new study reports. The advance provides new insights into the mechanisms of biomineralization and ...
