Illustration of fat cells. Nuclear power offers an efficient, reliable way to provide energy to large populations — as long as all goes well. Accidents involving nuclear reactors such as those that took place in 1986 at Chernobyl and at Fukushima Daiichi after the March 2011 tsunami raise major concerns […]

The Martian surface is a radiation hot zone. But these lava tubes might offer safety. Curiosity can handle the harsh radiation on the Martian surface. But people can’t. (Image: © NASA/JPL/MSSS/Marco Di Lorenzo/Ken Kremer) There’s no safe place to camp out on Mars. But a team of researchers has identified […]

Credit: Kristina Kvashnina An international team of scientists, led by the Helmholtz Zentrum Dresden-Rossendorf (HZDR), have found a new compound of plutonium with an unexpected, pentavalent oxidation state, using the ESRF, the European Synchrotron, Grenoble, France. This […]

They focussed their efforts on workers employed at the start of plutonium operations at the Sellafield (formerly Windscale) […]

Seven years later, traces of the disaster were found half a world away — in California’s wine. A group of French nuclear physicists tested 18 bottles of California’s rosé and […]
