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 无主房产七成产权收归国有， 如何回应“与民争产”之问？.
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.
While people in first-tier cities are under more pressure, smaller cities may not be the ideal place to live either, according to the 2016 Annual Report on Social Mentality of China by the Chinese Academy of Social Sciences.
An earlier plan by activists and the US-based Human Rights Foundation to send 100,000 copies of the film in January was postponed until after last month's Lunar New Year.

I experienced this pessimism personally in Davos in January 2014. Several leading western intellectuals asked me whether war would break out between China and Japan. I was so confident that there would be no war in east Asia that I offered to take bets with ten-to-one odds against myself with eminent western journalists. Two took up my bets. And I will be collecting on these bets when I return to Davos in January.
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.
"Students are not suited for starting businesses on their own," said Zhang, adding that vocational students are more eager to start businesses than university undergraduates.
It took almost 45 years for this 13-hour shaggy-dog experiment to reach American screens, but the timing turned out to be perfect. Mr. Rivette’s mischievous ramble through Paris, French literature and a handful of perennial philosophical puzzles (What is the nature of reality? How do we know what we know? What is the relation of effect to cause?) is both a charming, newly rediscovered artifact of its hectic time and a bulletin from the cinematic future. Everything has already been done, and everything is still possible.

Here are the 10 winners of the 2012 Ig Nobel Prizes given to scientists, writers, and peacemakers who make silly but thoughtful contributions to the world, or as the Annals of Improbable Research puts it, "first make people laugh, and then make them think." I can vouch for them making us laugh!
There's often an option to post your résumé anonymously, so do that, Foss says. "Or forgo that option and stick with LinkedIn," she adds. "You're way more likely to be found by recruiters and hiring managers there anyway."
Businesses can benefit in other ways too. Craig Rollason, business analysis manager at National Grid, says he has improved his coaching skills by mentoring a Teach Firster.
The captain must steer the ship. If leadership doesn’t know where a project or company is headed, how can the company know? This isn’t just about steps or deliverables, either, but a clear vision of the department or company’s future that he or she can communicate to the employees。
