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.

For the first time, it’s a blend of two colors: Rose Quartz (a kind of mineral pink) and Serenity (a light blue). On the company’s website, the colors flow seamlessly into each other so that it’s impossible to tell where one begins and the other ends.

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.

希萨柯既是一位不可或缺的政治导演,也是当代电影中的伟大诗人之一。他为北部马里圣战者管辖之下的生活所绘的图像既残酷又惊人,但也温柔、慷慨儿惊人的有趣。希萨柯并没有把暴力极端分子人性化,而是展示出,他们已经成了这种人,也反映出我们身上普遍的、悲剧的天性。但他的影片还坚持认为,反对狂热主义,唯一有效而且道德的方式就是人道主义。他以反讽而正直的方式言说了这一观点,或许最重要的是,以艺术的方式言说了这一观点。

"This is a hard one for people to understand how they're doing it, but it's an easy one for managers to pick up," Kay says. In many cases, you're disengaged, or as Kay describes it: "not being totally mentally present." Maybe you used to chime in a lot during meetings, and now you're quiet. Maybe you're not producing as much as you used to. Maybe you're not excited about a new project you've been asked to manage。

One of the most discussed potential use cases of the block chain is as a decentralized Uber. Instead of using an app, customers could order a car and pay the driver directly, cutting out the middleman. (Sorry, Travis Kalanick.) The block chain can be utilized for everything from the storage of secure documents (that is, a decentralized Dropbox, too) to “watermarking,” in which a specific coin could contain, say, the deed to your house. “The block chain is going to spawn decades of innovation,” says Ryan Selkis, director of investments at the Digital Currency Group, created by former SecondMarket founder Barry Silbert. “It could lead to things like frictionless share issuance, title transfers, smart contracts. Collectively these things make up the backbone of the economy. If you wanted to create a decentralized Uber, Dropbox, Facebook, you could reinvent the Internet.”
