A small US nuclear startup has quietly crossed a threshold that most young fission companies only talk about, achieving a self-sustaining chain reaction in a test system without ever boiling water or ...

Seventy years have passed since a team of 49 scientists, led by Italian-born Enrico Fermi, succeeded in creating the world's first self-sustaining nuclear chain reaction. Seventy years have passed ...

NEW YORK, Oct 7 (Reuters Breakingviews) - Artificial intelligence really has gone nuclear. The hulking energy demands of machine learning prompted the United States to sign off on reopening, opens new ...

During the early 1950s America went bonkers over the budding atomic age. The growth of Las Vegas, for example, was partially due to a new bomb-testing site situated 65 miles northwest of the gambling ...

Nuclear fission is a powerful phenomenon. When the conditions are right, atomic nuclei split, releasing neutrons that then split other nuclei in an ongoing chain reaction that releases enormous ...

The U.S. man-in-the-street had heard, but did not yet believe, that some day a scientist somewhere—perhaps in the U.S. —might press a button that would set up an atomic chain reaction and blow up the ...

December — Dr. Enrico Fermi achieves the first controlled nuclear chain reaction, with a natural uranium device moderated with graphite. Fermi conducted the process using the first demonstration ...

When President Donald Trump pulled the United States out of the Joint Comprehensive Plan of Action (JCPOA) — commonly known as the Iran nuclear deal — in 2018, many warned that it would set off a ...

On August 6, 1945, the sky above the Japanese city of Hiroshima opened. A blinding flash, then a deafening sonic boom. An entire city pulverized in seconds. Thus began the nuclear age. Today, 80 years ...

President Donald Trump has ordered preparations to resume U.S. nuclear weapons testing, citing alleged Russian and Chinese violations. Moscow and Beijing deny conducting explosive nuclear tests but ...
