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 不动产登记跑出“孝感速度”.
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.

The pair came out with a spree of punch lines, dishing them around the Beverly Hills Hilton, much to the delight of its starry audience. Mr. Damon, Meryl Streep and, naturally, Mr. Clooney were among the targets. Ms. Fey particularly had the crowd roaring with a description of 'Gravity,' which stars Sandra Bullock and Mr. Clooney.
Yunge from the Desert is based on an online novel with the same title by Tong Hua. It is about love triangle of a girl named Yunge, a nobleman, and the emperor in the Han (206BC-220AD). Nearly premiering in the same month as Nirvana in Fire, Yunge was much outflanked by the latter. It was criticized for its poor knowledge of history. To some audiences, charming Angela Baby herself became the only appeal of the adaptation.
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.

7. Flying Lotus “You’re Dead” (Warp) The new fusion makes no apologies for the old fusion, just a series of upgrades. As a producer, Flying Lotus values continuity as much as disruption, hazy beauty as well as jump-cut clamor. His suitelike reflection on death leaves room for irreverent wit — and, on “Never Catch Me,” one of the year’s best verses by Kendrick Lamar.
We need to ensure that our consumers will have access to good options, benefit from such consumption, and most importantly that Chinese companies will be able to win over the consumers with their commitment to high quality and workmanship.
Atlas Wearables founder Peter Li says battery technology and user retention are two more obstacles facing the wearables market. Some use cases require significant improvements to battery technology for a compelling experience, he says, and there’s always a balance to be struck between wear time between charges and processing power and features.
'Nebraska' gets to the heart of Bruce Dern's prickly old geezer, Woody Grant, by way of a road trip across Montana and Nebraska, shot in radiant black-and-white. (Here again one of the movie's stars is its cinematographer, Phedon Papamichael.) Alexander Payne directed, flawlessly, from Bob Nelson's stellar script, which is all about thwarted love, and reconciliation, between Woody and his son Will; he's played with painfully quiet eloquence by Will Forte. Here's the American heartland as it's seldom portrayed on screen, with humor and almost palpable fondness.
