Japan to be nuclear-free as last reactor switched off
Japan on Sunday began switching off its last operating nuclear reactor for an inspection, with no date scheduled for a restart amid strong public hostility towards atomic power.
World solar power capacity exceeds 100 gigawatts
World solar power capacity passed the 100 gigawatt mark for the first time to 101 GW, the European Photovoltaic Industry Association (EPIA) said on Monday.
Japan extracts 'fire ice' gas from seabed
Japan said Tuesday it had successfully extracted methane hydrate, known as "fire ice", from its seabed, possibly unlocking many years' worth of gas for the resource-starved country.
Search for element 113 concluded at last
The most unambiguous data to date on the elusive 113th atomic element has been obtained by researchers at the RIKEN Nishina Center for Accelerator-based Science (RNC). A chain of six consecutive alpha decays, ...

Mug handles could help hot plasma give lower-cost, controllable fusion energy
(Phys.org)—New hardware lets engineers maintain the plasma used in fusion reactors in an energy-efficient, stable manner, making the system potentially attractive for use in fusion power plants.
Probability of contamination from severe nuclear reactor accidents is higher than expected: study
Catastrophic nuclear accidents such as the core meltdowns in Chernobyl and Fukushima are more likely to happen than previously assumed. Based on the operating hours of all civil nuclear reactors and the number ...
Invention could make spent nuclear fuel useful for irradiation purposes
A researcher at Oregon State University has invented a way to use spent nuclear fuel to produce the gamma rays needed to irradiate medical supplies, food and other products – an advance that could change ...
Major cuts to surging CO2 emissions are needed now, not down the road, study finds
In 2004 a very popular study aimed to address climate change by deploying wedges of different existing energy technologies or approaches. According to the study by Robert Socolow and Stephen Pacala, each wedge would avoid ...
