(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.

戛纳电影节素以质问与嘲笑著名。在本届电影节上,《青木原树海》(Sea of Trees)成为第一部遭遇观众挑剔的电影。该片由格斯?范?桑特Gus Van Sant指导。在媒体放映场,《青木原树海》遭遇嘲弄的风暴,陷入了嘘声之海。由于这些发生在首映红毯前,恶评迅速传播,使得盛典蒙上阴影。娜奥米?沃茨(Naomi Watts )和 马修?麦康纳(Matthew McConaughey)走上红毯时,《每日电讯报》(Daily Telegraph)形容此场景为“极其糟糕却又引人瞩目的羞辱之途”。但是在随后的新闻发布会上,马修?麦康纳,这位来自德克萨斯的演员表情坦然,“每个人都有权倒喝彩,正如他们有权喝彩一样,”他说道。我相信我们都知道他的意思。

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.

但是我们波士士顿波士顿咨询集团不认为中国本次改革会导致中国经济不稳定。我们相信中国经济在习主席的领导下会持续高速增长。我们相信上个星期的改革(三中全会)会确保中国经济从现在一直增长到(至少)2020年。根据我们已掌握的资料,我们预测中国经济在未来10年会增加4万亿美金(而书中说是6.4万亿。2012中国GDP为8.3万亿美金)。如果加上印度,亚洲两大国未来的增长总量会达到10万亿美金。在此期间,中产阶级会迅速膨胀,进而增强对经济增长的乐观态度。当然,没有人能完美地预测未来,在我们的近期的一本关于中国和印度经济发展的书中(《Trillion Prize:Captivating the Newly Affluent in China and India》),我们也描述了一些经济增长缓慢的例子。不过总体上我们还是对中国的未来保持乐观态度。

If Mr Cook is guilty of missing the rapid growth of subscription services such as Spotify, he has moved swiftly to compensate for it — though for a high price.
