Their findings led them to conclude that the Earth' mantle history is more complex than previously thought. The researchers were astonished to find rocks that had not been remixed inside the mantle for two billion years. The rocks found beneath Gakkel Ridge, a 1,000-mile-long underwater mountain range between Greenland and Siberia, were precisely dated because of the presence of isotopes of osmium. As said the lead researcher, 'I just about fell off my chair. We can't exaggerate how important these rocks are — they're a window into that deep part of the Earth.' But read more for additional details and pictures, including a beautiful section of one of these 2 billion-year-old peridotite rocks."

Previously there was an older petition in 2005 which attracted over 11 thousand signatures, and both petition letters to IBM Corp can be seen at OS2World.com library. The End of Support period for OS/2 passed by in December 2006, and the given IBM's response the future for OS/2 doesn't look bright, except if re-implementation projects such as the Voyager or osFree attract the necessary critical mass of operating system developers."
