...realistic assessment. Globally, up to 3.7 million of such vehicles could be sold annually within the next few years, mostly in fast-growing markets like Brazil, China, India and Russia, says Abdul Majeed, a partner at PricewaterhouseCoopers in Chennai (formerly Madras). "It's all about affordability and fuel efficiency," says Majeed. "The very cheap car is a trend big manufacturers can't miss...
...might look like. But, "We should remove this perception of something that's going to be a dinky car," says Ravi Kant, managing director of Tata Motors. "It's a regular, wholesome car that will be a joy to drive and of course it will have very good fuel efficiency." Will that be enough to convince India's aspiring classes? Tata at the outset expects to sell 20,000 of its cheap cars a month in India, partly because consumers will see them as safer than motorbikes on India's chaotic roads. Ved Pal, 38, who works...
Fifty-eight seconds after launch, a fragment of ice or insulating foam once again broke away from the shuttle's external fuel tank and - once again - left a deep divot in the ship's insulating tiles. It was foam damage that killed the shuttle Columbia in February 2003, when superheated gases generated during reentry entered the ship through a breach in the insulation. Ever since then, astronauts have given their spacecraft a close visual inspection upon reaching orbit to look for any troublesome chips. On Sunday, a 3D laser imager attached to Endeavour's robotic arm revealed what could...
...activity as regulating sugar. Over a period of three years, Karsenty's team conducted a series of experiments with eight strains of mice, including some genetically altered to lack osteocalcin and some engineered to overeat. He found that osteocalcin significantly impacts how the body handles glucose, its primary fuel, in three ways: by raising the number of insulin-producing beta cells in the pancreas, by directly boosting the output of those cells, and by raising the body's sensitivity to insulin...
...work hints that a more basic, biological mechanism may be at work. The animals in his study were able to predict the amount of calories in a food based on taste, demonstrating that the body uses cues like taste and texture to make sure it's getting enough fuel. Just as Pierce's rats were fooled into thinking they hadn't absorbed enough calories after eating diet chow, people are preprogrammed to anticipate sugary, high-calorie fulfillment when drinking a soda or noshing on a sweet-tasting snack. So, the diet versions of these foods may leave them unsatisfied, driving...
