Containers made from plastics are used in most traditional greenhouse operations. While plastic containers are practical, strong, and can be formed to any size, shape, or color, the extensive use of these petroleum-based containers creates significant waste disposal problems for the greenhouse industry and consumers. One example: a 2008 report found that a typical greenhouse operation in California discards over 3560 pounds of plastic trays, flats, and containers annually.

Transparency builds trust. The phrase has become so axiomatic in corporate relations that it's inching perilously close to cliché. And while virtues of openness and transparency are well-established in the corporate world, they're even more essential when applied to the operation of city governments. A recent Knight Foundation/Pew Research study shows how important, demonstrating that if citizens believe their city governments behave in a transparent manner and make information easily accessible, they tend to think more highly about their town and its civic institutions.

The Deakin University invention uses waste heat to reduce friction by warming the engine oil. A prototype has been built and tested and the inventors are now talking to the car manufacturers and developing an aftermarket conversion kit. The system, which can be retrofitted, works by diverting waste heat to bring engine oil up to its optimal operating temperature. It was developed by researchers at Deakin University led by Mr Frank Will of the School of Engineering during his PhD project.

A carefully executed operation to validate data from CryoSat has shown what can be accomplished when ESA, NASA and others join forces to further our understanding of how the fragile polar environment is responding to climate change.

As manufacturers and other businesses step up efforts to cut waste, reduce energy use and improve the overall sustainability of their products and processes, the number of planet-friendly standards and regulations also is increasing at a rapid clip, creating a sometimes-confusing array of options for "going green." National Institute of Standards and Technology (NIST) researchers have prototyped a framework to help organizations of all types sort through the welter of choices and evaluate and implement sustainability standards most appropriate for their operations and interests.

An oil pipeline in northwestern US state Montana has ruptured and spilled crude oil into the Yellowstone River, a key tourist attraction in the region that runs through a famed national park, the pipeline operator acknowledged late Saturday.

University of Utah scientists used invisible infrared light to make rat heart cells contract and toadfish inner-ear cells send signals to the brain. The discovery someday might improve cochlear implants for deafness and lead to devices to restore vision, maintain balance and treat movement disorders like Parkinson's
