...machines have come a long way from the first karts pieced together from steel tubing and lawnmower engines in late 1950s California. Sure, karts typically lack gears, and there's no suspension to speak of. But there's often a push-button starter, a hydraulic disk brake, and a tiny onboard computer that measures everything from average speed to G-force. In the cadet class for the youngest competitive drivers like Nelson, the karts' 60-cc engines clock speeds of around 50 m.p.h. (80 km/h). The junior classes - open to racers from around 12 - have...
...interior also features heat-deflecting leather so the seat won't scorch you when you leave the top down. The six-speed manual transmission is buttery, particularly on the downshift. In town, a new feature prevents the car from rolling backward when you take your foot off the brake to accelerate after you've stopped at a light. The automatic has optional shift paddles. The 328i has a more than healthy 230-h.p. engine, although the turbo 335i model ($50,000) gets you to 300 h.p. These same power plants will be packed into new 128i and 135i coupes...

If dopamine receptors are the gas, the brain's own inhibitory systems act as the brakes. In addicts, this natural damping circuit, called GABA (gamma-aminobutyric acid), appears to be faulty. Without a proper chemical check on excitatory messages set off by drugs, the brain never appreciates that it's been satiated...
...number of accidents occurring on the shop floor because laborers could not read warning signs. More than just the workers' safety and Petrobras' productivity is at stake. The woeful state of education in Brazil, the world's fifth largest country, is compromising productivity and competitiveness and acting as a brake on the country's development, according to economists, businesspeople and educators. With the economies of China and India surging ahead, thanks in part to their large pools of educated workers, the issue has become an urgent one for Brazilian business...
...Fashion week is sponsored by Mercedes-Benz, so there were concept cars littered all over the tents. I would always say this as a last resort in my despair—I hate cars and have gotten into six accidents where I confused the gas and the brake, hitting inanimate objects, such as poles.“No!” Felicia would say, prying the cosmo from my hand. “You didn’t come here to see Anna Wintour, you came here to view a collection. Get to work...
