When genetically modified (GM) crops were first introduced, they were met with quite a lot of skepticism, not only in regards to their unproven long-term safety and efficacy but to their potential to be high-yield super crops. A three-year University of Kansas study has now confirmed the findings of a previous University of Nebraska study as to the yield abilities of the GM soybean from Monsanto: not only is the crop not a super-yield producer, it actually produces less than conventional yields, even under optimal conditions.

We slogged through the rain and traffic all the way across town to the Javits Center for the 2009 New York Auto Show. No, it’s not Detroit or Geneva; but the show still has a fair share of announcements, plus a chance to see up close those cars that recently debuted in other cities.

So far, it’s really been an American show—with big debuts by GM and Chrysler. It was also the year of retro design and nostalgia. Pontiac brought out three new models, including a yet-to-be-named revival of its former El Camino car/truck hybrid—extolled by rapper 50 Cent. Dodge took us back to the seventies, introducing three versions of its revived Charger model. And Mercedes waxed poetic about the glory days of the 80’s, when its belching diesel sedans ruled the upper-class subdivisions. It also introduced SUVs using its new BlueTec clean diesel technology.

When General Motors rolled out its "skateboard" vision for a fuel cell car at the 2002 Detroit auto show in January, there was buzz, and there was a big question. The skateboard concept, called Auto-nomy, was the product of GM's Design and Technology Fusion Group, and it radically reordered automobile physiology: Fuel cells, hydrogen, motor, and brakes were all crammed into a 15-foot-long, 6-inch-thick chassis onto which modular car bodies could be snapped. Drive-by-wire controls would plug into the skateboard's computer brain through a docking port.

Super-efficient light-truck engines are coming, but don't expect to notice.

That's the impression we came away with after driving General Motors' latest light truck concepts. The reason: something engineers call transparency, an effort to make new technology do its thing without anyone noticing.
