Submission + - Nuclear Nose Cones Mistakenly Shipped to Taiwan

Submitted by
Reservoir Hill
Reservoir Hill writes: "The Pentagon announced that the United States had mistakenly shipped to Taiwan four electrical fuses designed for use on intercontinental ballistic missiles, but has since recovered them. The mistaken shipment to Taiwan did not include nuclear materials, although the fuses are linked to the triggering mechanism in the nose cone of a Minuteman nuclear missile. Taiwanese authorities notified U.S. officials of the mistake, but it was not clear when the notification was made. An examination of the site in Taiwan where the components had been stored after delivery indicated that they had not been tampered with. The fuses had been in four shipping containers sent in March 2005 from F.E. Warren Air Force Base, Wyo., to a Defense Logisitics Agency warehouse at Hill Air Force Base, Utah. It was then in the logistics agency's control and was shipped to Taiwan "on or around" August 2006, according to a memo from Defense Secretary Robert Gates ordering Navy Adm. Kirkland H. Donald to investigate the incident."

Submission + - Suspended Animation Produced without Freezing

Submitted by
Predictions Market
Predictions Market writes: "Low doses of hydrogen sulfide, the toxic gas responsible for the unpleasant odor of rotten eggs, can safely and reversibly depress both metabolism and aspects of cardiovascular function in mice, producing a suspended-animation-like state that does not depend on a reduction in body temperature and include a substantial decrease in heart rate without a drop in blood pressure. The researchers measured factors such as heart rate, blood pressure, body temperature, respiration and physical activity in normal mice exposed to low-dose (80 ppm) hydrogen sulfide for several hours. In all the mice, metabolic measurements such as consumption of oxygen and production of carbon dioxide dropped in as little as 10 minutes after they began inhaling hydrogen sulfide, remained low as long as the gas was administered, and returned to normal within 30 minutes of the resumption of a normal air supply."Producing a reversible hypometabolic state could allow organ function to be preserved when oxygen supply is limited, such as after a traumatic injury," says Gian Paolo Volpato, MD, MGH Anesthesiology research fellow and lead author of the study. "We don't know yet if these results will be transferable to humans, so our next step will be to study the use of hydrogen sulfide in larger mammals." The full report is available online."
