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 红星美凯龙：首个财年利润65亿 筹建中商场还有466个！.
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.

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.
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).
The line of prescriptive frames and sunglasses, named “DVF | Made for Glass,” costs upwards of $1,600. Google has already partnered with Luxottica, the eyewear conglomerate behind Ray-Ban and several high-fashion eyewear offerings such as Prada.

The big question is what oil prices will do in 2015. Oil prices are unsustainably low right now – many high-cost oil producers and oil-producing regions are currently operating in the red. That may work in the short-term, but over the medium and long-term, companies will be forced out of the market, precipitating a price rise. The big question is when they will rise, and by how much.
