Rewriting Desktop Printer Can Erase and Reuse Documents


Figuring out how to recycle TPS reports and office printouts appears to have become a passion for Japanese engineers, as DigInfo News has discovered in recent days. If the "White Goat" machine that converts paper sheets into toilet paper failed to appeal, consider this supposedly eco-friendly printer that can erase old documents and reuse them up to 1,000 times per special page.

Green Dream: Swappable Switches

A wireless lighting system makes electrical switches portable

Most houses require hundreds of feet of electrical wire to connect light switches to a main power source, but not my eco-friendly dream home. I’ve installed a wireless lighting system called Verve that uses radio waves instead of copper wiring to command all the lights and outlets in my house. The system not only saves copper (imagine the savings in a skyscraper) but also lets me put switches wherever I want—beside the kids’ beds, in my pocket or even on the dash of my car—without the need to pull out wires or rip up walls.

Green Dream: Installing a Rooftop Garden

Rooftop greenery guards against water damage and bland meals

What’s a green home without actual greenery? I wanted my eco-friendly house to feel more connected to nature, so I turned the flat stretches of roof into gardens. Rooftop flora is not only scenic, but it can also protect a home against temperature extremes, absorb carbon dioxide, and triple the life span of a roof.

EPA Proposes Tighter Restrictions On Smog-Causing Emissions

The changes could cost industry $90 billion, and substantially improve Americans' health

In a move to curb smog, the Environmental Protection Agency (EPA) has proposed the tightest regulations ever on ground-ozone-causing emissions. The new standards would replace 2008 ozone regulations implemented by the Bush administration that allowed so much smog emission that environmental advocates took the EPA to court, arguing that the weak emissions regulation didn't actually protect people's health.

Scientists and Spies Team Up On Global Warming


In a break from their usual business of overthrowing South American governments, covering up alien landings, and broadcasting coded messages through my fillings, the CIA has revived a program that teams up spies and scientists for the study of climate change. Through the program, scientists get access classified images of the polar ice caps, as well as the chance to pick the targets of off-duty spy satellites.

Video: Wild Grouses Enticed into Mating With Sexy Fembot

It could happen to you

Oh, behave!:  Science Nation/National Science Foundation
One of America's strangest mating rituals, the chest-puffing, squeaking dance of the sage grouse, is getting closer attention, thanks to a pretty little fembot.

The sage grouse, which is sort of like a more interesting type of chicken, has long captivated scientists as well as tourists because, of its elaborate mating habits. A group of researchers have infiltrated the grouse world using a custom-designed "fembot" -- a robotic bird on wheels with a camera nestled in her breast.

Largest Iceberg Seen in a Century Now Floating Toward Australia


A massive iceberg twice the size of Manhattan is headed for Australia's southwestern coast, threatening shipping lanes in the Pacific.

The "superberg," called B17B, is roughly 1,000 miles off the coast of Australia and headed for warmer waters, where it will likely break up into many small pieces.

EPA Officially Declares Greenhouse Gases a Danger as Copenhagen Conference Begins

The U.S. signals its readiness to regulate carbon dioxide emissions; world leaders begin Copenhagen discussions on climate change

Today's symbolic but politically crucial move by the Environmental Protection Agency (EPA) recognizes greenhouse gases as a danger for humans and Earth alike. That would open the doors for new regulations on carbon dioxide emissions from vehicles, power plants and factories, according to the New York Times.

Human Blood May Hold the Secret to Clean Coal


As geologists probe the world's rocky sediments for spots to safely store carbon dioxide underground, engineers are working on the first step of the process: separating pure CO2 from noxious smokestack emissions. An enzyme in our blood already has the trick down, however, and it captures two pounds of CO2 every day. Now a New Jersey company is trying to replicate the method.

Study Finds Ozone Hole Repair Contributes To Global Warming, Sea Ice Melt

The 20th century's biggest environmental success may exacerbate the 21st century's biggest environmental crisis

In 1985, scientists from the British Antarctic Survey found a giant hole in the ozone layer of Earth's atmosphere over the South Pole. This discovery prompted a largely successful international effort to ban CFCs, the chemicals largely responsible for man-made thinning of the ozone layer.
