New sets adjust the color themselves whenever the light changes

To give you a perfect picture no matter how your room is lit, new TVs automatically tweak their on-screen colors to complement say, the orange glow of incandescent lights in the evening or the bluish tint of midday sunshine. We sat with two new self-adjusting screens by day and night to see if we could notice the changes.
Cheap, power-sipping sensors do everything from tracking global warming to keeping your house warm

The ability to scatter lots of wireless sensors over a wide area has tremendous potential, whether it's tracking the melting of a glacier, the stress on a bridge span or the temperature in your home. The trick? Making them cheap enough so you can use plenty, and having them last long enough so you don't break the bank or your back changing batteries (those trips to the glacier add up). This week, Microsoft showed us a prototype version of a wireless sensor that tackles both challenges.

Car engines have been governed by computers for years, but Honda’s iGX440 (honda.com) is the first power-equipment engine with a microchip. The electronically regulated iGX440which will show up in lawn mowers, water pumps and pressure washers later this yearruns at a constant engine speed even under changing loads. Thick grass usually causes mower engines to slow, bogging down whomever's pushing the machine, but the iGX440 maintains speed, and thus power, by giving the engine more gas and manipulating ignition timing.
