New sensor for detecting plastic explosives
Zinc complexes are naturally fluorescent, but they lose this ability when exposed to chemicals contained in plastic explosives, a phenomenon called quenching; since zinc complexes react by losing different amounts of their fluorescent ability, they can be used to create sensor arrays that produce a different visual display when exposed to different explosives

Nuclear proliferation looms, I
Owing to rising oil prices and worries about climate change, there is a growing interest in nuclear power generation; forty countries have told the UN nuclear agency of plans to develop nuclear power generation capability; experts worry that this interest in nuclear technology is fueled at least in part by interest in nuclear weapons - especially in Middle Eastern countries terrified about the rise of a nuclear-armed Iran

Next-generation nuclear fuel may be too hot to handle: report
It sounded like a good idea: Enrich the uranium used to power nuclear reactors further so that operators will be able to extract more electricity from a given amount of fuel; trouble is, burn-up rates above a certain point would violate U.S. Nuclear Regulatory Commission’s safety standards unless new methods were devised for packaging the fuel
