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 “两材”旗下9家上市公司昨临停.
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.
Quite a few students were disillusioned by UK visa regulations. “A lot of people saw the programme as a gateway to employment in Europe,” says one. “If this was the objective, then a lot of them would have gone away unfulfilled.”

The developer behind Kinect Disneyland Adventures and Elite: Dangerous is taking the theme park business to the extreme in ScreamRide. The game lets players build outrageous roller coasters, thrill rides and attractions from the ground up and then take them for a test run. The game offers three ways to play: Engineers can construct elaborate rides that test the boundaries of physics and g-forces; Scream Riders get on these rides and experience the thrills and spills first-hand – sometimes resulting in untimely deaths; and Demolition Experts can use any means necessary to tear down an entire amusement park. With classic PC games like Roller Coaster Tycoon now playable on smartphones, this next generation of thrill-ride creator is a welcome interactive experience. It’s always fun to build, ride and destroy roller coasters – and ScreamRide offers plenty of ways to share the thrills with your friends.
Mr. Lyons took a casting of Ms. Swinton’s mouth and designed teeth to fit. Those were clipped on over Ms. Swinton’s real teeth. For Minister Mason, he came up with a quirky look but didn’t quite want it to be comical. He was, however, interested in adding a little bling. “There’s a little bit of gold on the left-hand side,” he said. “We used real gold to make the filling of one tooth. We did it to put more character into the character.”
