France's global nuclear fusion device a puzzle of huge parts

A hugely ambitious project to replicate the energy of the sun is entering a critical phase, as scientists and technicians in southern France begin assembling giant parts of a nuclear fusion device, an international experiment ...

How seawater could corrode nuclear fuel

Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 -- and that was probably the best action to take at the time, says Professor Alexandra Navrotsky of ...

Quantum dots visualize tiny vibrational resonances

In the late 18th century, Ernst Chladni, a scientist and musician, discovered that the vibrations of a rigid plate could be visualized by covering it with a thin layer of sand and drawing a bow across its edge. With the bow ...

New technique could improve detection of concealed nuclear materials

Researchers have demonstrated proof of concept for a novel low-energy nuclear reaction imaging technique designed to detect the presence of "special nuclear materials"—weapons-grade uranium and plutonium—in cargo containers ...
