Researchers uncover earliest tobacco use in the Pacific Northwest

UC Davis 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 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 .

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 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 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.

Belgium, for example, has less than a tenth of the population of Russia, its rival in the group stage, but is regarded as a far greater threat. And then there is Uruguay, which despite fewer than 4 million citizens -- barely a sixth of the population of greater S?o Paulo -- is one of the teams Brazil would least like to meet on its way to the final. How is this so?
Texas was one of the first states to emerge from the recession and it continues to attract companies on the basis of its low tax burden, predictable regulatory environment and skilled labor force. Texas employment is expected to expand 3% annually through 2017, according to Moody’s. (Arizona’s forecasted rate is a microscopic 0.04% better). Texas has attracted a lot of attention from California companies and Governor Rick Perry has not been shy about contrasting the business climates of the two states. California firms EBay and Electronic Arts have both chosen Texas for large expansions in recent years. Austin has been a hotbed of activity this year with Accenture

Prior to this recent testing, which used sensitive gas chromatography/mass spectrometry, researchers were unsure of the historical use of tobacco on the 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.

Uruguay owes much of its success not just to its passion for football but also to the early inclusiveness of its culture. In that 1950 tournament, at a time when neighboring Brazil still regarded its black players with suspicion, Uruguay boasted a black captain, the brilliant Obdulio Varela. Moreover, Uruguay's victories in the World Cup's formative years established a pedigree that endures to this day, with many of its footballers -- such as Liverpool's Luis Suárez and Paris Saint-Germain's Edinson Cavani -- playing abroad for some of the world's biggest clubs.

The ranking includes schools from 26 countries, including 35 in the US, 10in the UK and nine in China. Renmin University of China School of Business in Beijing rose furthest, climbing 18 places to 43rd. Four schools made it into the ranking for the first time. These are led by Cambridge Judge Business School at 36th. France’s Grenoble Business School is ranked 70th, Turkey’s Sabanci University School of Management is at99th, and Brazil’s Coppead is at 100th.

A jailed con artist who falls in love with another inmate and escapes prison multiple times could only be the work of fiction, but this is more or less the real story of Steven Jay Russel. Much like his film counterpart, played by Jim Carrey, Russell was originally sent to prison for fraud. He escaped his first sentence to be with his partner Jim Kemple, who at the time was dying from AIDS. Russell was found two years later and returned to prison. Kemple died soon after.
Slow growth around the world won't hurt the U.S. all that much. American exports might flatten out or even dip, but that would be offset by lower imports of petroleum because of sinking oil prices. So the trade deficit is unlikely to get further out of whack.
The report also shows that despite the rising pension insurance balance since 2012, the payable number of months fell to 17.7 months last year from 19.7 months in 2012.
