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.

A Honda executive privately attributed much of its troubles on “bad luck,” as opposed to shoddy business practices or deliberate misbehavior on anyone’s part. Perhaps.

本地社交媒体广告,即那些恰好出现在你的Twitter和Facebook信息流之中的广告,在2013年爆炸式增长。2014年,无论你爱也好,恨也罢,这类广告的规模只会变得越来越大。,尽管听起来有点让人毛骨悚然,但特定位置定位技术预计将在来年出现显著改进。Twitter刚刚推出了一项面向特定邮政编码区域发送有偿消息的功能。比如,当你走进一个社区,当地酒吧、干洗店和麦当劳(McDonald's)发布的“推广消息”就会突然闪现在你的Twitter信息流之中。自2011年来,Facebook一直在采用这种“地理围栏”技术。它能够让商家招揽临近的客户,这些客户实际上可能也想获得提供特别优惠和特价商品的广告信息。好处是,你可以获得更多相关的广告和推销信息。缺点同样是,更多的广告。

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.

Remedy: The tricky aspect of this regret is that it’s typically rooted in hindsight. Only after you’ve left the job and have moved on to something better, do you start beating yourself up for not making the leap sooner, even if it hadn’t been practical or possible. What you can do is to identify the factors that kept you in your former position as red flags to be aware of in the future and work to line up supports that will allow you to more quickly capitalize on other opportunities as they may present themselves. This could include reviewing and updating your resume with new accomplishments on a monthly or quarterly basis, keeping your LinkedIn account current, building up a contingency fund to allow you to feel less tethered to your current pay check and staying in the loop on industry news and gossip to be aware of where your skills and experience could be of value.
