OSLO (Reuters) - Large tracts of ice on the Arctic Ocean have halved in thickness to just 1 meter (3 ft) since 2001, making the region more accessible to ships, a researcher said on Tuesday.
"There was loose ice everywhere we went," Ursula Schauer, leader of a scientific expedition aboard the Polarstern ice-breaker, told Reuters by telephone from the Arctic Ocean north of Siberia.
"All of these areas have previously had two meters of ice," said Schauer, who works at the Alfred Wegener Institute in Germany, of a trip from Norway around the North Pole and back towards Russia. The last major survey was in 2001.

Should organics be tested for GMOs?
A recent disturbing incident of GMO contamination of organic soybeans raises the question of whether organic foods should be tested for genetically modified material. The US National Organic Program (NOP) rules prohibit GMOs in organics but don’t require methods to prohibit GMO contamination or establish thresholds for adventitious GM presence. The Organic & Non-GMO Report asked organic industry experts if organics should be tested for GMOs.

New Fingerprinting Method Tracks Mercury in Environment
September 16, 2007 12:10 PM - Paul Schaefer, ENN
ANN ARBOR, Mich.—With mercury polluting our air, soil and water and becoming concentrated in fish and wildlife as it is passed up the food chain, understanding how the potent nerve toxin travels through the environment is crucial. A new method developed at the University of Michigan uses natural "fingerprints" to track mercury and the chemical transformations it undergoes. A report on the work is published today in Science Express.

Knee arthritis may be sign of early lung cancer
September 16, 2007 11:34 AM - Anthony J. Brown, MD, Reuters
NEW YORK (Reuters Health) - Having isolated arthritis in one knee could be an early warning sign for lung cancer, Italian researchers suggest. "Knee monoarthritis as an early manifestation of lung cancer has never been described previously," Dr. Fabrizio Cantini, from the Hospital of Prato, told Reuters Health. He noted that the knee trouble in such cases appears very early, "with the consequent possibility of surgical removal of the cancer." The researchers reviewed the medical records of everyone with isolated knee arthritis seen at their center over a 6-year period, and report their findings in the Annals of the Rheumatic Diseases.
