Some asteroids have measured densities higher than those of any elements known to exist on Earth. This suggests that they are at least partly composed of unknown types of "ultradense" matter that ...

The first-ever discovery of an extraterrestrial radioactive isotope on Earth has scientists rethinking the origins of the elements on our planet. The tiny traces of plutonium-244 were found in ocean ...

Since element 99—einsteinium—was discovered in 1952 at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) from the debris of the first hydrogen bomb, scientists have ...

Feb. 3 (UPI) --Scientists have, for the first time, measured the bond distance of einsteinium, one of the most radioactive and difficult to make elements on the periodic table. Researchers detailed ...

Researchers from Australian National University have discovered the first ever extraterrestrial radioactive isotope on Earth. The discovery is causing some to reconsider the origins of elements on ...

The nuclear accident in Fukushima remains etched into people's memories. It was a catastrophe that caused huge amounts of radioactively contaminated water to be released, which the operators of the ...

Polly Arnold is drawn to challenging problems at the far reaches of the periodic table. “It’s all about the f block,” she says of the work in her group, which is split between the University of ...

Japanese scientists have made a new (nu?) periodic table organized by the number of protons in the nucleus instead of the element’s number of electrons. They call it the Nucletouch table, and where ...

Since element 99 -- einsteinium -- was discovered in 1952 from the debris of the first hydrogen bomb, scientists have performed very few experiments with it because it is so hard to create and is ...
