(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.

'Increased production in the U.S. meant that spot prices weren't reacting quite as much as in previous geopolitical incidents,' Mr. Hansen said. There is so much supply that threats to it have less impact than previously, and 2014 will be 'the first year in a while when supply growth is going to outpace demand growth,' Mr. Hansen said.

为什么我如此有信心东亚不会爆发战争,无论在东中国海还是南中国海?答案很简单,因为我了解推动亚洲变化的力量。虽然许多亚洲邻国会发出愤怒的民族主义声明(他们必须这样做来应对普遍的民族主义情绪),但他们的行动是谨慎和务实的。

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.

为了尝试遏制煤炭消耗量的增长,中国正在可再生能源和核能领域投入巨资,但尽管付出了这些努力,中国迄今为止依然是最大的温室气体排放国。中国每年因化石燃料燃烧和水泥生产排放100亿吨二氧化碳,几乎是美国的两倍,但美国的人均排放量依然远远高于中国。

She never finished high school, and says she “could write before she could read.” Now, she is invited to places like Stanford University and fends off comparisons to Emily Dickinson.
