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 2016年LED产业现微增长趋势.
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.
"How to tie a tie" was the No. 1 question in 2010, followed by "how to lose weight", "how to kiss" and "how to write a resume."
A lot of the best James Bond theme songs sound like they belong in a lounge act. That's not a complaint, just an observation. For whatever reason, the English new wave act Duran Duran was given free reign to provide A View to a Kill with a new and exciting sound all its own. "A View to a Kill" was a hit song, and it probably would have been a success even without the James Bond connection. It's entertaining and cool and energetic, and it promises one hell of a good time. (Whether or not the movie actually lives up to that promise is a matter of some debate.)

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.
The private Facebook group chat that led to offers of admission being rescinded was named, at one point, "Harvard memes for horny bourgeois teens", the Crimson reported.

In contrast to last year when the vast majority of economists expected the ECB to launch full-scale quantitative easing, just under half of the 33 respondents thought the ECB would do nothing this year. The rest said the ECB would expand QE or cut interest rates, although some of those who expected more easing stressed that the central bank was unlikely to radically reshape its existing policy response.
The 5.5-percent increase this year is reasonable given a less anticipated consumer price index (CPI) as well as slower salary and GDP growth, said Jin Weigang, head of the social security research institute under the MOHRSS.
Dealers: Car dealers work toward reducing the paperwork involved in buying a car and the hours it takes to fill it out. That will give them more time to devote to upselling add-ons such as extended warranties, paint and fabric protection, and rust-proofing.
