The Manhattan Project that built the atomic bomb wasn't without its own dangers. Experiments on a so-called "demon core" of plutonium caused the deaths of two Manhattan Project physicists. Both ...

I think we can all agree that the physicists, engineers, and chemists who worked on the Manhattan Project -- which ultimately ended World War II -- were consummate geniuses and paragons of ...

Have you heard of the Demon Core? Though it sounds like some kind of a superstitious group, rest assured that is not what it is. Instead it refers to the time in which scientists at the Los Alamos ...

After these two incidents, the demon core was eventually melted down, as the second criticality accident had made it not ready for use in Operation Crossroads, the 1946 Bikini Atoll tests. It was ...

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 so-called Demon Core was a cursed object, a 6.2 kilogram mass of plutonium intended to be installed in a nuclear weapon. Instead, slapdash experimental techniques saw it feature in several tragic ...

Plutonium is a radioactive, silver metal that can be used to create or destroy. While it was used for destruction soon after it was made, today the element is used mostly for creating energy ...

The U.S. has nearly 4,000 stockpiled nuclear weapons, and Scientific American wonders what will happen to all of their aging plutonium cores. Experts have said the plutonium will last at least 100 ...

Of all the abductions, this one is different.
