NASA Satellite Tracks Movement of Pollution from East Asia to North America
It turns out our Chinese imports aren't limited to just cheaper goods - pollution accounts for a fairly hefty slice. In fact, that pollution may be equivalent to a not trivial 15% of local emissions in Canada and the U.S. This is

Luna Gaia: The Green Side of the Moon
Here's one for the apocalyptic, techno-nerdy and ecological design enthusiast alike: "Luna Gaia," a lunar habitat designed international team of scientists, engineers and grad students that'll make dwelling on the moon not only almost entirely

Where Does all the Carbon Dioxide End Up?
We imagine most of you, upon reading the post's title, will have already (and accurately) guessed the short answer: the atmosphere and the oceans (for the most part). But, to delve further into the matter, where exactly in the atmosphere or the oceans

Palau and Pentagon Looking to Harness Solar Energy from Space
Reprising a topic we've covered before - the harnessing of solar energy from space - we bring you the latest on a joint venture between the U.S. Department of Defense and Palau to test the feasibility of using satellites to beam

Searching for the Planet's Sunniest Spots
Wouldn't it be great if there were a technology or database in place to locate the world's sunniest spots? Not only could it help spur further investment in solar energy technologies by giving businesses or governments the best bang for their buck; it

Arctic: Ice-Free by 2013?
The passage of time has not been kind to the Arctic's fortunes: Where scientists once predicted the Arctic would be ice-free by the end of the century, they revised their estimates in recent months to 2030 and now - stunningly - to 2013. Presenting the

A Sunburnt Country's Embarrassment of Energy Riches
We've mentioned before that Australia's cup runneth over when it comes to energy sources. The world's largest uranium reserves (40%), and the world's largest coal exporter (30%). But now the good news. A 2001 CSIRO study apparently found that

A Picture is Worth... A High-Definition Antarctica
This new map of Antarctica, deemed the "most geographically accurate, true-color, high-resolution views of Antarctica to date" (and 10 times more detailed than previous views, to boot), was constructed by a team of researchers from the British

Katrina and Rita Responsible for Nation's Worst Ever Forestry Disaster
As devastating as Hurricanes Katrina and Rita may have been, the amount of pain and destruction they inflicted on Louisiana and Mississippi may have just been a prelude to the larger ecological disaster they now

Create the Future: Entries to NASA's Design Contest
Electricity-producing roads, a zero-energy home and a smart rainwater collector (the last two are pictured above) are just a few of the cool sustainable designs entered in NASA's Create the Future Design Contest. The contest, which tasks entrants to

Fancy an Inflatable Car?
You'd certainly be hard-pressed to find a more lightweight car than XP Vehicle Systems' Whisper this year - or one that could also withstand a 25-foot fall. Yes, while some of their lofty claims may seem dubious (safest car "ever"?) and some of their

Checking Out the Sun's Surface with a Solar Telescope
Scientists are planning to send a balloon-borne solar telescope on expeditions in the polar regions to gather an unprecedented amount of data on the sun's surface. Following a successful test flight earlier this month during which the telescope -

NASA Satellite Pictures Capture Wildfires' Breadth
NASA's Terra and Aqua satellites have been busily recording the breathtaking scope and speed with which the Southern California wildfires have been spreading over the past few days, abetted in large part by strong, dry Santa Ana winds. The image, which

Carbon Dioxide Production Much Faster than Originally Anticipated
About all that carbon dioxide we've been spewing into the atmosphere - yeah, it's worse than we thought. That seems to be the main take-away message of a new study by an international team of researchers that found that current carbon dioxide

Earth Elevator Technologies are so Last Year
The fact that nobody has ever won the 2007 Space Elevator Games - which seeks to find the best elevator technology to easily shuttle supplies and people to and from a space station (or hotel) in orbit around Earth - did little to dampen the excitement

PolarPalooza Is Coming To Town
Look out Al Gore, the PolarPalooza is bringing the good word on climate change to communities all across the US, and it hits San Diego this weekend. The event is dubbed the PolarPalooza because, "like the rock tour, we hope to be a little out of the

Downloading Designs: How NASA Uses This Technology
On August 8, 2007, 58 seconds after the space shuttle lifted off, falling foam struck the heat tiles near the right main landing gear door. Not interested in having a repeat of the Columbia disaster, NASA had sent up a laser camera system from Neptec,

Tin Whiskers Out With The Claws, Bricking Satellites and Pacemakers
There's something sprouting in every electronic device that you own, and it's not in the oh-happy-garden-let's-pick-the-fruit kind of way. In fact, this little something could very well end up bricking your device. They are called tin whiskers, and
