Heavy water is not just heavier. Swapping each H in H2O with a D — hydrogen’s isotope deuterium — changes many of water’s properties. Heavy water is poisonous, and its freezing point is 4° Celsius, ...

A material that is a hundred thousand times heavier than water and more dense than the core of the Sun is being produced at a university. The scientists working with this material are aiming for an ...

Scientists have long felt that the ideal source of energy would have to be nuclear fusion. It's the same process that powers the sun, and there's something elegant about the notion of two atomic ...

Selective process Deuterium molecules (shown in grey) can change the structures of the DUT-8 pores and pass through the material. The orange molecules of normal hydrogen cannot pass through. (Courtesy ...

Nuclear physicists at the Argonne National Laboratory in the US have obtained the first results from a new spectrometer that contains the magnet from a mothballed MRI machine. They used the Helical ...

Scientists who strive toward achieving thermonuclear power—the controlled fusion of hydrogen—have fooled themselves so many times that they are reluctant to claim success. But last week in Washington, ...

To most of the U.S. public the hydrogen bomb was still a direful novelty last week, but to scientists there was little new about it. Long before the discovery of uranium fission they had known that ...
