Joel Achenbach writes about science and politics for The Washington Post's National desk. He has been a staff writer for The Post since 1990. He started the newsroom’s first online column, Rough ...

Nuclear facilities simply heat water and turn turbines with the steam produced. Controlling the fission reaction (essentially the rate of release of neutrons to sustain that reaction) is where it ...

Russia had seriously considered using nuclear weapons in Ukraine, but was dissuaded from doing so by China, U.S. Secretary of State Antony Blinken has said. Amid repeated nuclear threats from ...

From the lightest Hydrogen isotopes up to the recently synthesized Oganesson (Z = 118), it is estimated that as many as about 8,000 atomic nuclei could exist in nature. Most of these nuclei are too ...

Fast radio bursts (FRBs) are extraordinary, fleeting explosions of radio waves. These signals, often originating from neutron stars or black holes, last for just a millisecond but carry immense energy ...

This past year, there has not been a single week without a reminder of the danger posed by nuclear weapons. Nuclear noise and signaling were evident; officials made implicit or explicit references to ...

China’s rapidly expanding nuclear power industry passed a major milestone on New Year’s Day, as the first reactor at a sprawling new plant on the country’s southeastern coastline started ...

A new high-tech atomic clock has been developed by scientists at the top-secret Defence Science and Technology Laboratory (Dstl). It is expected to be a leap forward for intelligence, surveillance ...

Troops on military operations will soon be able to use a British-made atomic clock built with quantum technology instead of GPS for the first time. The quantum clock, which in the next five years ...

Read and combine data from the Atomic mass evaluation (AME) and NUBASE data files into a single array (std::vector) which can then be manipulated as required, or written to files for use with other ...

Read the paper: Frequency ratio of the 229mTh nuclear isomeric transition and the 87Sr atomic clock So researchers are working on a nuclear clock – a device that would harness the energy levels ...
