...hole anxiety has in fact bubbled up into the public consciousness.) But while such scenarios have been ruled out, the machine does pose a small threat to the scientists overseeing it: There's a constant risk of a helium leak, high concentrations of which quickly depletes the tunnels of oxygen...
There's a furious argument over whether shorts hastened the demise of Lehman and AIG, cutting the off their oxygen when it was desperately needed. And some have laid the blame at the feet of SEC commissioner Cox. "Chris Cox is responsible for the largest destruction of wealth in U.S. history," hissed Mad Money maestro Jim Cramer on his CNBC show on Tuesday. "Because of Cox, the shorts won." (Republican nominee John McCain called Thursday for Cox to be fired - the same Cox some conservatives touted as a possible running mate earlier this year. President Bush said he fully supports...
...having just given birth to her second child. She had started bleeding from a tear in her cervix, the blood forming a pool on the floor below. Two doctors ran in and stitched her up, relatives found blood supplies, and nurses struggled to connect a generator to the oxygen tank. One nurse jammed an intravenous needle into Conteh's arm, while another hooked a bag of blood to a rusted stand, and a third slapped an oxygen mask over her face. In the corner of the room, a tiny baby--3 hours old--lay on a bed, wailing, swaddled...
...simply improved versions of the average Sunday runner. They are physiologically different. For example, a typical human has in his skeletal muscles an equal balance of "fast-twitch" muscle fibers (quick contracting, easily fatigued muscle tissue that generates high power) and "slow-twitch" fibers (the muscle mass that uses oxygen - aerobic, rather than anaerobic), on which endurance runners rely. Slow-twitch muscle can contract for long periods of time with less fatigue, which helps some distance athletes run up to 60 mi. per day. Sprinters legs are genetically blessed with 70% fast-twitch and 30% slow-twitch muscles, which...
...Ocean Living with Dead Zones According to a report published in the journal Science, the number of dead zones--areas of the ocean with oxygen levels so low that marine life can barely survive--has doubled every 10 years since the 1960s as a result of a runoff polluted with nitrogen-rich crop fertilizer. There are now more than 400 such zones--from the Gulf of Mexico to the Black Sea (see map above)--which, the report's authors say, pose as great a threat to coastal ecosystems as overfishing and habitat loss...
