Western Antartica's immense glaciers are melting fast and giving up ice to the sea at a rate that is considered already past "the point of no return," according to recent research work done by two different groups of scientists. The resulting scenario is compelling: an increase in the world sea levels of 4 feet or more in the next centuries, according to findings announced Monday by scientists from the University of Washington, the University of California-Irvine and the Jet Propulsion Laboratory at NASA. "It truly is a startlingly disturbing situation," says Pennsylvania State University glaciologist Sridhar Anandakrishnan, who was not associated with any of the research studies. "This is a big part of West Antarctica, and it appears to have been pushed violently over the edge." The researchers claim the glaciers are most certainly bound to be lost. One study confirms that a river of ice named Thwaites Glacier is possibly starting to collapse and that complete collapse is likely to occur. A second research illustrates that six glaciers are giving up ice into the sea at an ever-increasing rate. At that rate, there will be a 4-feet increase in the sea-level, states study author Eric Rignot, a glaciologist at the University of California-Irvine, and NASA's Jet Propulsion Laboratory.

Researcher studies crystal growth that may lead to biomaterials for both and tooth repair In nature, some organisms create their own mineralized body parts--such as bone, teeth and shells--from sources they find readily available in their environment. Certain sea creatures, for example, construct their shells from calcium carbonate crystals they build from ions found in the ocean. "The organism takes brittle carbonate and turns it into a structural shape that protects it from predators, and from being bashed against the rocks," says Lara Estroff, an associate professor of materials science and engineering at Cornell University. "There is much scientific interest in how the organism controls the crystal growth, and what mechanisms are involved in strengthening and toughening the shells, especially in comparison to their components, which are brittle."
