(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.

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.

比特币发展势头强劲的另一个指标是,接受比特币的主流企业数量增加。2014年,微软、贝宝、戴尔以及Dish Network等企业宣布,自身一系列产品接受比特币付款。此前已有塔吉特(该公司接受能以比特币购买的Gyft)、Overstock.com以及WordPress等公司接受比特币。就连《财富》出版商——时代公司,也开始接受比特币杂志订阅。去年,雅虎还将比特币加入其雅虎财经跟踪网站,令比特币更显正统。谷歌财经也很快依样画葫芦。雅虎发言人向CoinDesk网站表示:“接受比特币越来越普遍,我们觉得这与我们行业、我们用户切身相关。”假如雅虎很快更大力押宝比特币——不论是收购比特币新创企业,还是宣布其他动作——都别太惊讶,因为雅虎首席执行官玛丽莎o梅耶尔正努力使这家止步不前的搜索巨头变得更时髦。
