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.

Next year will be the 60th anniversary of the beloved talking bear. And to mark the occasion, Paul King, who directed 2014’s critical and commercial smash, simply titled Paddington, is back for this sequel. In a time where even children’s entertainments are suffused with darkness and violence, this quiet celebration of the everyday English is needed more than ever. The plot of this film? Well, not much really: following the events of the last film, Paddington is quite comfortably installed with the Brown family of Windsor Gardens. He wants to buy a pop-up book for his aunt from a local bookseller, but finding himself a few quid short he puts on his wellies and duffel coat and finds employment in various odd jobs – only to have the book stolen from the shop! A (not so serious) mystery begins. Expect many more jokes about Paddington’s love of marmalade. Released in the UK November 10, November 23 in Germany and November 30 in Cambodia and Malaysia.

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.

We will ensure that foreign trade continues to pick up and register steady growth.
'Cutie and the Boxer' was hardly noticed by the movie-going public, but a list of fine films isn't a rundown of box-office triumphs. The reach of Zachary Heinzerling's debut feature-length documentary is equaled by its grasp. On the surface it's about nothing more-or less-than a troubled marriage that has somehow managed to last 40 years. Beneath the surface, then startlingly out in the open, is a history of rivalry (both husband and wife are artists), enmity, reluctant devotion and, most startling of all, enduring love.

Remedy: Make a budget. If you don’t know how much money you need to live the lifestyle you feel comfortable with, you can’t accurately project whether switching jobs for a $10K pay bump is actually a good deal. Making a pros and cons list when comparing your current job with a new opportunity is also helpful. If the only advantage a job offers is a bigger pay check, you can weigh that against longer hours, a more onerous commute and increased reporting responsibilities. Keep in mind that research shows that increases in happiness based on earnings peak at about $75K. Incomes above this level don’t increase your feeling of well-being on a day-to-day basis. So, if you think a jump up to $85 or $90K will make you feel less morose when your alarm goes off, you might want to look at addressing some of the non-monetary factors in your life that are contributing to your dissatisfaction.
