University of Washington developers are working on vocal joystick software that can direct a mouse pointer on a computer screen, making for a hands-free voice controlled mouse. Check it out in this short article and accompanying video in Science Daily.
If you didn't feel guilty about your TV habits already, here's a new reason: a chemical used in making flat-screen televisions has been found to be a potent greenhouse gas, 17,000 times stronger than carbon dioxide. In a study published in the journal Geophysical Research Letters, atmospheric chemist Michael Prather called nitrogen trifluoride, or NF3, "the missing greenhouse gas," and warned that the climate could suffer as the chemical is produced in ever greater amounts to meet soaring demand for LCD displays. If all of the NF3 produced in 2008 were released into the atmosphere, it would have as much warming effect as 67 million metric tons of carbon dioxide. NF3 isn't covered by the Kyoto Protocol because it was only being produced in tiny amounts in 1997 when the treaty was negotiated. Ironically, NF3 was developed as an alternative to perfluorocarbons, greenhouse gases that are governed by Kyoto.

Professor Rima Taher, a civil/structural engineer, teaches at the New Jersey Institute of Technology and New Jersey School of Architecture. She says building design and construction can be significantly improved to reduce wind pressures on building surfaces and to help better resist high winds and hurricanes in residential or commercial construction.

Located at Carnegie Mellon, the Green Design Institute is a "major interdisciplinary education and research effort to make an impact on environmental quality through green design." The primary goal of the Institute is to form partnerships with industry, government, and other foundations in order to develop processes that "can improve environmental quality and product quality while enhancing economic development."
Visitors to the site may wish to begin by reading the "About Us" section to learn a bit more about the Institute. Perhaps the most useful section of the site can be found by clicking on "Education" where courses and course materials on environmental issues are available.
This series of lectures is provided by Cambridge University's Applied Superconductivity and Cryoscience Group. They feature contributions from leading world experts in academia and industry and are available free of charge.
As the project continues, there are plans to add supporting text, questions, and links to further reading for each lecture. Each lecture includes several chapters, each with an accompanying video. In addition to the video lectures, the site includes links to other related educational resources, an image gallery, and a bibliography of papers and publications related to the lectures.
