Countdown begins for China’s first spacewalk: Shenzhou-7 spaceship launches into orbit with 3 Chinese astronauts
(quote)
After three decades of hoping, 10 years of training, and at least 12 hours preparing his spacesuit, Zhai Zhigang is expected to make history in just 20 minutes tomorrow as the first Chinese astronaut to do a space walk. The 42-year-old former fighter pilot will don a £2m, ten-layered Chinese-designed suit, weighing 120kg (265lb), to exit the Shenzhou VII module.
The Chinese Shenzhou VII spacecraft blasted off at 9:07 p.m. Thursday, carrying three Chinese astronauts into space on this country’s third manned space mission in five years. The Chinese government has spent billions of dollars in recent years building up a space program that it hopes will help China establish a space station by 2020 and eventually will put a man on the moon, accomplishments that would certainly bring the country international prestige.
Large Hadron Collider hibernates after wrong sort of big bang caused by hellion leak, to re-awaken in Spring'09
(quote)
Two weeks ago, the most powerful atom smasher to be built had been switched on to global acclaim and scientists were ready to begin experiments that could unlock many of the enduring mysteries of the Universe. They are going to have to wait a little longer. On Friday the Large Hadron Collider (LHC) created the wrong sort of big bang - a fault so serious that CERN, the European Organization for Nuclear Research, announced last night that the particle accelerator would have to be shut down until next spring for repairs.
Preliminary investigations into the incident, in which a huge quantity of helium leaked from the LHC’s cooling system, have suggested that it was caused by a faulty electrical connection between two of its superconducting magnets. The fault affected a part of the accelerator that is kept chilled to within 1.9C of absolute zero, and it will have to be warmed up to room temperature before the problem can be understood fully and resolved. It will take at least three to four weeks to warm the affected sector and then to open the damaged magnets for inspection, and then another month to re-chill them to their operating temperature. read more »
"Do I really want that CT scan?" Study shows increased radiation exposure, cancer risks, tests often unnecessary
(quote)
CT scans can be better medicine for doctors than for patients - they provide detailed views of internal organs, but the price is increased doses of radiation. A chest CT scan is equivalent to about 100 X-rays.
When Maureen Scanlan had a painful kidney stone episode four years ago, she was pleased that her doctor ordered an annual regimen of CT scans to monitor her condition. The scans involved hundreds of razor-thin X-rays of her innards stitched together by a computer into stunningly detailed 3-D images showing the size and location of the stone, down to the millimeter. What she didn't realize was that the perfection of the images was a result of a radiation dose equivalent to more than a dozen standard abdominal X-rays -- all for a condition that though painful is relatively mundane.
All-electric car, 240+ miles per charge, 0 to 60 mph in under six seconds, to be built in San Jose Tesla factory
(quote)
The specs for Tesla Motor's new car are in: an all-electric, four-door, five-seat sedan that gets in excess of 240 miles per charge and accelerates from 0 to 60 mph in under six seconds. It will be built in what the company is calling the "greenest auto manufacturing plant in the world" on the outskirts of San Jose, Calif., the self-proclaimed world headquarters of clean technology. In other words, the car of the future is on its way here. Eventually.
Winning a $250m (£139m) deal with electric car maker Tesla to base its new factory there, the city beat other contenders to secure a project that will bring more than 1,000 jobs to the area. "This is a big step toward being the center of world cleantech innovation," said San Jose Mayor Chuck Reed. Tesla boss Ze'ev Drori said that "this is proof the time has come for the electric car."
The company plans to produce an all-electric luxury sedan, called the Model S, at the plant with a retail price of around $60,000 (£33,000.) It already manufactures a two seater zero emission Roadster which sells for $109,000 (£61,000) and is built by Lotus in England. read more »
World first fuel-saving carbon-cutting program: Air New Zealand passengers take a ride on the 'perfect flight'
(quote)
Air New Zealand's "perfect flight" using optimal flying conditions and the co-operation of US, New Zealand and Australian aviation authorities, was hailed as a success in San Francisco on Friday. Using new technologies and procedures on a flight from Auckland, Air New Zealand cut waiting time, trimmed flying time, saved 1,200 gallons of fuel (around 4% less fuel than normally used), eliminated 30,000 pounds of harmful carbon emissions and took a quieter approach on arrival at San Francisco International Airport.
The normal commercial flight NZ8, dubbed ASPIRE 1 (Asia and South Pacific Initiative to Reduce Emissions) is the first tailored test flight on the Pacific using technology and cleared gates at each end, eliminating air traffic congestion to test flight and fuel efficiency. It is part of a worldwide drive to make the aviation industry more environmentally friendly. read more »
Biggest physics experiment in history underway: Large Hadron Collider passes operational test, fires first beam

There was screaming and whistling in physics labs and auditoriums outside Geneva - and around the world - Wednesday, as scientists whooped it up out of sheer joy.
Electric tank-car of the future? The Hinterland 1 Concept Car - an electric minivan with Prius-like aerodynamics
(quote)
It has the profile of a Toyota Prius interpreted by the late Maxime Faget, designer of the Space Shuttle. It's the Hinterland 1, a conceptual all-electric minivan with a drag coefficient of less than 0.25 (the Prius's is 0.26). And if its designers get their way, it'll become a Canadian icon on par with the CN Tower, Geddy Lee and Poutine. Existing purely as sketches, renderings, and specs at this point, the Hinterland 1 electric car looks like one part tank, one part VW bus with a pinch of bullet train added for flavor.
Chief designer of the Hinterland 1 is Matin Aube of Creative Unit, a veteran of Québec- based Bombardier Recreational Products, maker of the Sea-Doo watercraft, who says the project "combines sources of artistic, technical and scientific expertise" from recreational vehicles, electric motors and batteries, aeronautics, aluminium, plastics processing and video games. In theory, the sculpted body would comprise an aeronautical-style aluminum monocoque, fashioned by the same hydroforming process GM uses to create body panels for its curvy Pontiac Solstice roadster. A drive system proposed by electric-car startup Higgins-Aubé would involve a 43 kW-max motor (14kW continuous) powered by Li-ion or Zebra (Sodium Nickel Chloride) batteries with a maximum power of 37,000 kilowatts. Designers envision two models built on the same platform, a two-seater "Mini" and the six-person "Van." read more »
