In the current climate of rising gas and food prices, it should stand to reason that people would find ways to change their most wasteful habits. According to new research from the UK, we need look no further than our own refrigerators. Fully 18 percent of all food purchased for household use in England and Wales is thrown away. The number is even higher for families with children at 27 percent. A now four year-old study of similar measure in the U.S. puts the American number around 14 percent, with nearly half of all food readied for harvest never making it to a dinner table.

Flowers are known to attract pollinating insects through a variety of means, from alluring fragrances and nectar to vibrant colors and shapes. According to a new study in the Read Full Story ]

Bioplastics, like biofuels, are on the rise as consumers demand alternatives to fossil fuel-based plastics and big business take their wants seriously. Everything from shopping bags to clamshell containers are being reengineered out of bio-based packaging in the hope of finding a truly disposable container; one that, instead of ending up floating in the ocean, will quickly decompose underground. That ideal, as you might expect, is not quite so simple. And already, our two leading alternative bag types are falling short of the hype.

The small airplane is too dirty for an environmentally threatened world. That’s not the view from eco-activists, but from some of the leading lights in general aviation—the category encompassing small planes such as Cessnas flown by citizen pilots. “At some point, some environmental group is going to figure out that small aircraft fly leaded fuel,” said Mark Moore, NASA’s personal air vehicle program manager, to a meeting of engineers, aviation advocates and a billionaire corporate titan with his own private jet. Their goal, however, is not to bury private aviation, but to remake it as the greenest form of personal transit.

There is an element of "why did it take so long?" in reports surfacing of the zero-watt monitor from Fujitsu Siemens. It's a flat panel LCD which contains a relay switch that automatically interrupts the power supply when the video signal from an attached PC subsides. Instead of going into standby when idle and consuming a low voltage, the monitor consumes none at all. When the video signal returns, the relay switches the other way and electricity is returned to power up the monitor.

If technology were a religion, the Xerox Palo Alto Research Center would be one of the holiest shrines on any pilgrimage. So much of our modern computer world was invented at this freewheeling innovation lab (and largely given away). Prefer your mouse and point-and-click graphical interface to a UNIX-style command line? Thanks PARC. Think laser prints look better than dot-matrix scrawl? Thanks again.

Some say the glory days have passed. PARC today is a more-focused operation that has to turn quick profits (no more open funding from it’s owner Xerox). But it’s still a well-staffed corporate research lab in an era with ever-fewer of those creatures. On Monday, its staff opened the doors to the press to show off the latest gizmos.

In a slow-motion shock to environmentalists worldwide, European countries are turning back to coal to fire new power plants. At a time when India and China are ramping up production in their outdated coal-burning facilities, the last place anyone expected to see a coal resurgence was in the generally progressive nations of Western Europe. Most turning again to coal are hamstrung by record oil and natural gas prices; Italy and Germany have the added stress of having banned new nuclear plants as an alternative.

I've seen hand-held solar chargers before—the Solio immediately comes to mind—but I've yet to see a functional wind-powered hand-held charger. Enter the HYmini. It's palm-sized, comes in three colors, costs 50 bucks, and can charge your gadgets with nothing but a stiff breeze. Well, almost. While it's a welcome idea, on closer inspection, the feature set isn't all we'd like it to be.

People around the world guzzle about 50 billion gallons of bottled water a year, and then toss billions of those plastic bottles into the trash heap instead of the recycling bin. Matt Naples and Peter Zummo think they can take this lemon of a fact and turn it into lemonade—or rather, take those discarded water bottles and turn them into chairs, shelves, or houses for the world’s poor.

In 2007, registrations of new hybrid vehicles jumped by 38 percent to 350,289 vehicles, according to a new report from R.L. Polk & Company. Gee, I wonder why? Maybe it's got something to do with rising prices at the pump, or climate change. Or maybe there's something bigger at play.
