The battle to reduce carbon emissions is at the heart of many eco-friendly efforts, and researchers from the University of Missouri have discovered that nature has been lending a hand. Researchers at the Missouri Tree Ring Laboratory in the Department of Forestry discovered that trees submerged in freshwater aquatic systems store carbon for thousands of years, a significantly longer period of time than trees that fall in a forest, thus keeping carbon out of the atmosphere.

You may think penguins all look the same, but a computer system on a South African island knows better. It can identify individual birds from subtle differences in their plumage.

The technology could help researchers monitor threatened populations without using more invasive methods that can distress or harm the birds.

After last year's thin ice cover, the North Pole is poised to vanish due to global warming in a short time

DailyTech has previously covered the frantic pace of melt in Greenland, which is accelerating, dumping vast amounts of water into the sea. Meanwhile, the North Pole has been steadily melting away as well. Fortunately, the North Pole ice is floating, and thus will not affect sea levels, but its dissolution is an important indicator of warming.

The U.S. Green Building Council (USGBC) first released LEED for Existing Buildings: Operations and Maintenance (LEED-EB) in November 2007. The reference guide for the system is due out in June 2008, and, as of July 1, all projects seeking certification must register under the new version.
