...they are. It's accepted, based on various studies, that between 4% and 18% of people who are resuscitated after cardiac arrest have an NDE. Researchers tend to fall into one of two camps. The first argues that an NDE is a purely physiological phenomenon that occurs within an oxygen-starved brain. "There's nothing mysterious about NDEs," says Mark Mahowald, director of the Minnesota Regional Sleep Disorders Center. "Many people want it to be a religious, paranormal or supernatural phenomenon. The fact that NDEs can be explained scientifically detracts from the mystique...
...profile, medications, religion and previous knowledge about NDEs all appeared to be irrelevant. To this day, Van Lommel can't explain why some people have NDEs and most don't. But the fact the experience isn't universal undermines, to his mind, a purely physiological explanation: if lack of oxygen were the cause of NDEs, then all survivors of cardiac arrest should have...
...Science is trying to solidify the brain-based theory of NDEs, which goes something like this: Survival is our most powerful instinct. When the heart stops and oxygen is cut, the brain goes into all-out defense. Torrents of neurotransmitters are randomly generated, releasing countless fragmentary images and feelings from the memory-storing temporal lobes. Perhaps the life review is the brain frantically scanning its memory banks for a way out of this crisis. The images of a bright light and tunnel could be due to impairment at the rear and sides of the brain respectively, while the euphoria...
Screwcap proponents would argue that cork?s unpredictability has driven this trend. Taint is part of this, but so is another factor: oxygen. A typical wine cork contains millions of air-filled cells, but because every cork is different, some winemakers think they cause inconsistent aging of the wine. Screwcaps let in less air, and since their cellular composition is man-made, adopters like Bonny Doon say the caps offer a more controlled oxidation process that allows wine to age as the winemaker intended. (Plastic corks, meanwhile, still control a larger corner of the alternative-stopper market than screwcaps...
...aftermath of that tragedy, federal law was rewritten to require miners to have wireless communication systems, and to provide them with respirators containing more than the one hour of oxygen the Sago miners had. But the law hasn't gone into effect yet, and it wouldn't have speeded up the rescue effort in this case. The rescuers had only gone about 800 ft. by yesterday evening - and there's no reason to believe the trapped miners are alive, or that they even survived the first collapse. Boreholes drilled from above into the chambers where the miners might have found...
