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 2017年商品房销售量价创新高 房地产行业整合加速.
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.
This slide in the dollar value of exports has entirely been a price effect, driven by lower commodity prices. In volume terms, emerging market exports have continued to rise since 2014, even if volume growth in year-on-year terms has moderated to around 2 per cent, a fraction of the double-digit rates witnessed either side of the global financial crisis, as the second chart shows.

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 Baltic Dry index, a measure of the trade in bulk commodities, has been touching historic lows. China, which in 2014 overtook the US as the biggest trading nation, this month reported double-digit falls in both exports and imports in January. In Brazil, which is experiencing its worst recession in more than a century, imports from China have collapsed.

It was a confident, high-powered investment firm with credit lines at top financial institutions. It made big bets using borrowed money to buy assets and generate higher returns. But when the market for those assets went south, lenders demanded more collateral until the firm suddenly collapsed.
