Researchers uncover earliest tobacco use in the Pacific Northwest
(Phys.org)—Native American hunter-gatherers living more than a thousand years ago in what is now northwestern California ate salmon, acorns and other foods, and now we know they also smoked tobacco—the earliest known usage in the Pacific Northwest, according to a new University of California, Davis, study.
"The study demonstrates that tobacco smoking was part of the northwestern California culture very early ... shortly after the earliest documented Pacific Northwest Coast plank house villages," said the study, published in the 欧司朗CEO提议拓展通用LED照明市场 遭西门子抨击.
Testing organic residues extracted from pipes, researchers from the UC Davis Department of Anthropology and the Fiehn Metabolomics Laboratory of the UC Davis Genome Center confirmed tobacco was smoked, and likely grown in the region, by at least A.D. 860.
Perhaps more importantly, the researchers say that additional studies may help them better understand the origins of nicotine addiction and the human management, geographic range extension and cultivation of tobacco. Indeed, as part of a second study, the authors have recently detected nicotine in ancient pipes from an 800-year-old site in the modern city of Pleasanton, Calif.

That even at a lower profit margin (say, 40%) and a 1/3 cannibalization rate (i.e. customers buy one third fewer full-priced iPhones), the cheaper iPhone would increase Apple'srevenue and gross profits (see her spreadsheet above).
Prior to this recent testing, which used sensitive gas chromatography/mass spectrometry, researchers were unsure of the historical use of tobacco on the Pacific Northwest Coast. It was unclear, for example, whether European traders had brought tobacco to the area much later, or if some other plant had been smoked in the pipes, Tushingham said.

Taken together, these events and strategic initiatives highlight the Chinese aerospace industry’s realization that, in order to become a globally competitive player, it will need depth as much as breadth. After getting their hands on both ends of the value chain—aircraft design and final assembly—the Chinese now understand that what will make or break their industry over the long term is what happens in the middle of the value chain, at the component and subsystem levels. And that is why China’s ambition to compete with Boeing and Airbus, as well as with GE and Rolls-Royce for aircraft engines, is now more credible than ever.
In the meantime, the sheer total of bitcoin-related startups that launched in 2014 demonstrates bitcoin’s momentum. There is no definitive listing of every single bitcoin startup, but 2014 almost certainly saw the launch of more of them than in any year prior. Data that AngelList sent to Fortune confirms that. In 2011, five bitcoin startups listed themselves on AngelList. In 2012 that number grew to 13. In 2013 it jumped to 193, and last year it exploded to 566. (But not all startups register on AngelList immediately, if at all.) In addition, on January 8 the total number of daily bitcoin transactions hit an all-time high, as Barry Silbert eagerly tweeted.
