    On this month??s cover is an image from April 1972: astronaut John Young jumps as he salutes the US flag (which, we worked out, is why he appears to have no shadow, you conspiracy theorists). It??s the Apollo 16 mission to the Descartes region of the Moon, in which Young and fellow astronaut Charles Duke made three excursions in a 71 hour visit. They covered 26km in their Lunar Roving Vehicle, which is parked in front of the Lunar Module. In the background is Stone Mountain. View full abstract»

    The article discusses how well UK manufacturing can weather the gathering economic storms.UK industry had enjoyed a three-year run of monthly growth in production, and there was hope that it could prove to be resilient to recession as long as manufacturers could continue to pass on the ever-increasing costs of raw materials to their customers. But this long-term trend appeared to hit the buffers when the Chartered Institute of Purchasing and Supply reported flat growth and pointed out that it was the emerging picture across a range of manufacturing sectors.

  • Back to the moon [space NASA anniversary]

    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (228 KB)  

    This year marks NASA's 50th anniversary. Piers Bizony looks at the venerable space agency's plans for a return to the Moon. Can old glories be revived? From now on, Nasa's principal task is to "undertake extended human missions to the Moon, with the goal of living and working there. With the experience and knowledge gained on the Moon, we will then be ready to take the next steps of space exploration: human missions to Mars and to worlds beyond". The ageing space shuttle system will be retired from flight in the year 2010, and a new spacecraft, the Crew Exploration Vehicle (CEV), known as Orion, will take centre stage. View full abstract»

    The article presents the Lunar Boom Town, a virtual reality game endorsed and funded by NASA. Lunar Boom Town is an interdisciplinary concept that promotes the exchange of open information in an effort to understand the details of successful space colonisation in terms of technology, business, environmental sustainability, and policy. It was created by the participants of Wikiversity - a project developed by Wikimedia. View full abstract»

    I am saddened that the usually excellent E&T should include a rant against pro-lifers and the Catholic Church regarding the use of embryos (`Cloning cures??, Vol 3, #11). I am a `pro-lifer?? and a Catholic and I take exception to Philip Hunter??s disparaging remarks about my views on when human and spiritual life begin. View full abstract»

    We¿re very good at making things go extinct ¿ dodos being perhaps our most famous victim, although contrary to popular belief, we didn¿t eat them to oblivion, in fact they tasted horrible. But this loss was, at least in our modern minds, an `accident¿, and we didn¿t mean it to happen. But what about deliberately engineering an extinction? View full abstract»

    The history of science must necessarily be a chronicle of overthrows, with one explanation replacing another. One of the greatest overthrows was the displacement of Ptolemy??s geocentered cosmology with the Copernican solar-centered system. One prime disruptor, Galileo, was later put under house arrest for propounding a world view too much at odds with canonical ideas. View full abstract»

  • Powered down [electronics low-power

    Low-power design involves so many design tweaks, it needs a verification approach all to itself. Just about every analysis of chip design claims verification consumes more than half of the time needed today to bring a semiconductor system to market. How much more varies depending on the target application, though it is also m probably fair to say that one area & feeling greater pain is mobile communications. View full abstract»

  • Design freedom gets the brush-off [electronics design]

    Various techniques have been used to push processes this far past the point where diffraction effects kick in. These have included using phase-shift masking to turn diffraction to the designers' advantage, and optical proximity correction (OPC) techniques, such as adding 'ears' to the corners of layout elements so that they are printed as right angles. The problem is that chipmakers are applying ever more Byzantine combinations of these techniques to keep up with shrinking process dimensions, and getting diminishing returns. Device characteristics are varying wildly as more aggressive OPC techniques are pressed into action. The chip equipment industry has been working to solve this for years, but couldn't persuade its customers that moving to 157nm illumination sources was worth the development costs given the marginal advantages it would bring over 193nm light. Unfortunately, the development of EUV lithography is fraught with difficulties. The solution to the 65 nm and 45 nm design for manufacture is new DFM routers. As they are DFM-aware they can run the rule-based checks and ensure that around 80 percent of the DFM problems are avoided. The layout team can then use model- based DFM to take care of the remaining 20 percent. View full abstract»

  • Hi robot! [control robotics]

    Microsoft founder Bill Gates likens the challenge of putting robots in every home to that faced by the PC pioneers, as they attempted to put a computer in every home. Despite the difficulties, the level of excitement and expectation reminds the author of the time during the convergence of new technology when one dreamed of the day when a computer would be on every desk.

    Drax is one of the largest power stations in the UK, supplying around 7 per cent of the UK??s electricity with six generator sets, each rated at 660MW. Construction of the plant began in the mid 1960s, with the first phase coming on line in the 1970s and the second phase in the 1980s, with it being in continuous operation ever since.

    A controlled experiment, perhaps: divide a country in two, and feed only one half properly. One way to see the importance of good nutrition is to look at the countries on each side of the Demilitarised Zone on the Korean peninsula. In North Korea, plagued by endemic food shortages for decades, average heights are 18cm shorter than in richer, better fed South Korea. View full abstract»

    There are many good reasons for pursuing renewable energy, quite apart from climate change. The first and obvious reason for interest in renewable energy is that it is renewable. Thirty-five years ago, it was thought that almost everything was about to run out. View full abstract»

    Spam accounts for around 95 per cent of all business email sent by most estimations, so the occasional piece of junk mail is bound to slip by the filters. More often than not, the message seems to be so obviously spam that users can only conclude that they could do a better job than the technology; but, in truth, the human mind is too susceptible to outside influences to ever beat the machine.

    This article discusses about 'the server virtualization project'. The project started in 2007, at that time there is around about 50 physical servers and there was a consideration to reduce server footprint. Eventually it was decided on a partner to be used that was the best fit for Nuttall, and this was FoundationlT. The project gave a very satisfactory result into a production environment, and assured to be a sound and secure system. The project achieved to be cost saving and shown commitment to being 'green' too. View full abstract»

    A flash of lightning is being unleashed at motor shows this summer. Designed and developed by The Lightning Car Company in Peterborough, UK, the Lightning GT electric car has impressive engineering roots. It also created the Ronart series of Jaguar-powered racers and Vanwall high-performance sports cars. The vehicle's chassis has recently been re-designed mainly to accommodate the all-important battery pack. View full abstract»
