...fiasco has been autopsied many times--it is the stuff of books and business-school case studies--and yet I can't help reaching for the rib spreader one more time. Here was an early and definitive illustration of message revenge, the kind of fierce consumer blowback that can occur in markets when a product or service (or military occupation) fails to live up to its hype. Consumers, it turns out, regard their passive absorption of mass advertising as an investment of psychic space; to the extent that they allow themselves to become aroused with anticipation, they consider their credulity...
...football field, to borrow a phrase from sports-injury researchers, is an impact-rich environment. Players frequently knock heads, but it's hard to predict which of the many hits will result in brain-rattling concussions, which are relatively few in number and--contrary to popular belief--often occur without loss of consciousness. Eight colleges, including three Big Ten schools, are using the team version of Riddell's high-tech helmets, which wirelessly relay real-time data--gleaned from the same sensors found in car air bags--to a sideline computer that can send a pager alert if a player...
...least partially driven by the fact that global warming has emerged as a top concern among voters in Australia, which has suffered through years of extreme drought. The opposition Labor Party, which has pledged to sign the Kyoto Protocol, is leading in most opinion polls, and an election will occur before the end of the year. "Environmental issues have moved to the center of mainstream politics here," says Cook...
...what theory? REM (rapid eye movement) sleep is the relatively active brain state in which most dreaming is thought to occur. REM intrusion is a disorder in which the sleeping person's mind wakes up before his body does. He feels awake, yet the muscle paralysis of REM can remain; he may also hallucinate until mind and body get back in sync. "Lay people think you're either awake or asleep," says Nelson, "but you needn't go directly from one to the other...
...Nelson's theory goes some way toward explaining how NDEs can seem to occur when the brain is down. The sleep/wake switch is in the brainstem, which helps control the body's most basic functions and stays active for longer than the higher brain in cardiac arrest. "It's likely that the transition to brain death is, in fact, gradual," says Mahowald, "and NDEs occur during this transition." As for people reporting accurately on events that went on around them while they were apparently unconscious, Nelson says "they may be seemingly out of it but still processing in a very...
