When small is big: Tinier chips demand less energy and could produce a cellphone that needs a battery charge only once a month.
The global high-tech industry is suffering significant production losses as Japan's dominant semiconductor manufacturers struggle to resume operations. South Korean firms are moving to fill the void.
A Massachusetts Institute of Technology student tweezes a silicon wafer that, under high heat, will grow carbon nanotubes, some of the smallest conductors yet invented.
Nuclear experts told Congress Wednesday that spent-fuel pools at US nuclear power plants are fuller than safety suggests they should be. They say the entire US spent-fuel policy should be overhauled in light of the nuclear crisis at Japan's Fukushima plant.
Nobody expected that a tsunami would affect Japan's nuclear plants. And climate change will raise the possibility of such awful, unlikely happenings around the world.
The devastated Fukushima Daiichi nuclear power plant has become the latest poster child for long-standing issues surrounding nuclear energy – issues that need to be resolved to reduce the risk of a similar nuclear crisis in the United States. These range from the seemingly eternal conundrum over dealing with highly radioactive spent fuel, to fire hazards, plant design, and emergency plans, say nuclear engineers and nuclear-safety watchdogs.
An NRC report finds that 28 percent of US nuclear power plant operators did not share information on defective parts with federal regulators. 'Confusion' over reporting rules is blamed.
New York Gov. Andrew Cuomo calls the Indian Point nuclear power plant near New York City a 'catastrophe waiting to happen.' Federal nuclear power regulators promise to make Indian Point, which sits near a fault, a top priority in their review of seismic hazards.
State and federal legislators voice concerns about the earthquake risk at two California nuclear power plants – as well as the adequacy of safety protocols in place there.
