...this leaves Null's believers with a decidedly mixed message. For those willing to go panning through his books looking for the gold mixed in with the sediment, there's a lot to be had. For many consumers, particularly seriously ill ones, that may simply be too much to ask. Null himself acknowledges that staying healthy can be a difficult business, requiring people to rip out the very foundation of their beliefs about health care. The problem is, some of what he's replacing it with feels a little wobbly...
UCLA geochemist Frank Kyte thinks he may have found not just the answer but also a piece of the thing itself: a tiny meteorite fragment, a tenth of an inch across, that was extracted from a 65-million-year-old geological layer under more than 50 yds. of sediment at the bottom of the Northern Pacific. In a report in the current issue of Nature, Kyte notes that the little chunk contains concentrations of metals (such as iridium and nickel) and mineral textures that clearly show that it is extraterrestrial and that it probably was once part of a much...
...down (it really is--you can track it across the sky), causing colors to punch out and deepen. I'm fly-fishing in peerless blue water--yellow sunlight bounces off the surface--and fat lunkers lurk below. When one at last strikes at the red-feathered lure, lake-floor sediment swirls like a dust cloud...
...effective wildlife habitat for murrelets, Pacific giant salamanders and the spotted owls that loggers love to hate. In particular, they offer little protection for coho salmon, listed as threatened in the state. Salmon need cool, shaded, clear streams for spawning. Aggressive, steep-slope logging cuts shade and pours down sediment. This is no secret, but the state has not enforced regulations to protect salmon streams, and the new Headwaters legislation, say critics, stipulates buffer zones too narrow to be effective...
...Jobs notes, "Look, you work on a technical product, and if you're really lucky, it ships. If you're really, really lucky, it's a hit and lasts a year. If you're in the pantheon of products it lasts a decade, then it rapidly becomes a sediment layer on which the next layer of technology is built. I don't think you'll be able to boot up any computer today in 20 years...
