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 安置房3号楼不到俩月土方过半.
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.
We will promote coordinated urban development above and below the ground, and begin construction on at least another 2,000 kilometers of underground utility tunnels in cities. A three-year initiative will be launched to remove the risk of flooding in highly vulnerable urban areas; and further progress will be made in the development of sponge cities. All these efforts will make our cities more attractive and function better.
Rios is no stranger to hard work. She moved to the U.S. from El Salvador when she was a child. She graduated at the top of her high school class and raised a family while putting herself through college. She was not intimidated when she started Nation Waste Inc. At just 22, months after graduating from the University of Houston, she took out loans and purchased two trucks, jumping into the male-dominated waste-removal industry. Today, her Houston-based company has 24 full-time employees. "It is pretty amazing when I look back and see, I started as a little girl entering the United States with my parents and now I am truly living the American dream," says Rios.
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.
Her subjects felt like they were waiting in a long line to reach the top of a hill where the American dream was waiting for them. But the line’s uphill progress had slowed, even stopped. And immigrants, black people and other “outsiders” seemed to be cutting the line.

When he was offered the role of "Will" on Fresh Prince, he had 70% of his wages garnished for the first three seasons. After three years, he was able to take home his full salary. Basically, the first line of the theme song could have been written about Will Smith's real life: "This is a story all about how/My life got flip-turned upside down." Except in real life, the "guys making trouble in his neighborhood" was the IRS.
But the UK courts may land a heavy blow on ride-hailing app Uber. In 2017, the California-based company failed to persuade an appeal judge that two of its London drivers are independent contractors. In 2018, the test case will go to the Court of Appeal and possibly to the Supreme Court. If Uber loses the case and is told to assume the responsibilities of an employer, the implications will ripple far and wide.
As institutions are brought under dictatorial control, the opposition is driven into rebellion or acquiescence.
