"LOS ANGELES — After a five-year delay, an Earth-observing satellite will be launched to test new technologies aimed at improving weather forecasts and monitoring climate change."

"A breakthrough in oil cleanup technology allows crews to skim spilled oil off the water's surface at a much faster rate. The new device wasn't developed by Exxon, BP or any of the major oil companies — it's the work of Elastec/American Marine, based in Illinois. And the design won the company a rich prize from the X Prize Foundation.

Oil is attracted to plastic. And water is not. That, in essence, is the basis of Elastec's new skimmer.

"For more than half a century, International Molasses Corp. has sold its product to bakeries and manufacturers that use the sticky syrup in cookies and candy.  But recently, the Saddle Brook company found a new and unexpected market — at contaminated industrial sites, where the molasses literally gets pumped into the soil."

"RECYCLING refrigerators — especially those made more than 15 years ago — is a tricky job. The coolant in old appliances (now banned from newer versions) can cause serious trouble, warming the atmosphere and depleting the ozone layer."

"A defunct NASA satellite the size of a bus that is expected to fall to Earth on Friday will likely miss North America, NASA said.

The agency's 13,000-pound (5,900 kg) Upper Atmosphere Research Satellite, or UARS, has been slowly tumbling from orbit since its mission ended in 2005. It is expected to re-enter Earth's atmosphere and break apart on Friday."

The UARS satellite played a historic role in investigating the atmospheric chemistry behind the stratospheric ozone hole, and has been replaced by more advanced instruments gathering additional data.
