Last month, as expected, the four partners in the International Thermonuclear Experimental Reactor (ITER) project announced a three-year extension of the ITER engineering design activity. Detailed design work on the next-generation fusion-energy device started in 1992 and has cost about $1 bn so far. A decision to build the device, once scheduled to be taken […]
The results show that the limited quality of conventional X-ray images can be dramatically improved by exploiting synchrotron light (D Chapman et al. 1997 Phys. Med. Biol. 42 2015). Moreover, there is no need for a high radiation dose. Ineffective radiology has a big impact on society. Relatively high X-ray doses can overcome the limitations […]

The laws of quantum mechanics can be used to process and transmit information in ways that are not possible with existing systems, Anton Zeilinger says
There is more to information than a string of ones and zeroes - the ability of "quantum bits" to be in two states at the same time could revolutionize information technology
China is one of the fastest growing nuclear energy markets in the world. Only one per cent of China’s energy needs presently comes from nuclear power and over the next fifteen years China will spend $60 billion on nuclear reactors. To keep costs down China is pushing hard for foreign investment in its nuclear programmme, […]
HAARP is a facility to study upper atmospheric and solar terrestrial physics. The programme is paid for by the US Air Force and Navy and has already cost hundreds of million dollars. Opponents of the project believe that the defence department is studying ways of improving communications with the US submarine fleet. The array acts […]
Plessey will join Mitel’s semiconductor division to form one of the world’s top ten manufacturers of communication semiconductors. Plessey is the 11th company that GEC has sold since September 1996, as it tries to focus on its core businesses of defence and aerospace, telecommunications and industrial electronics. Plessey is renowned for its application-specific integrated circuits […]
The growth of virtual reality has increased demand for more realistic video displays, but existing head-up display helmets are expensive and difficult to use. Gerard de Wit and Joseph Braat at Delft have developed a retinal scanning display (RSD) which uses less power and offers higher resolution than current models. RSD works by adapting the […]
The committee was set up by Newt Gingrich, speaker of the House of Representatives, to update the famous 1945 report by Vannevar Bush, The Endless Frontier, that has formed the basis of US science policy for the past 50 years. Ehlers is vice-chairman of the House of Representatives science committee. Remarkably, Gingrich has given the […]
The broken promise has led to disagreements between the government and the utilities companies that operate nuclear power plants. Underlying the conflict is the fact that the DOE has charged electricity users literally billions of dollars to cover the costs of building a site for the burial of radioactive waste. More than 40 000 tons […]
