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.

Now Chinese investment in western economies is back on track to break a further record this year: during the first six weeks this year Chinese groups have announced $70bn in potential deals, although the number is highly provisional and not all such acquisitions will be completed.

所以我不知道2014会发生什么——谁也不知道。但在我的想象中,它会是这样的:

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.

Recent initiatives to support two-way tourism between the two countries include the trial of the 10-year visitor visa; the open aviation market services arrangement which removes all capacity restrictions for airlines on both sides; and a new Beijing to Sydney service by Qantas Airways which was launched in January.

This is not to take anything away from Tesla, which has demonstrated that it can create and manufacture a complex and sophisticated product with demonstrated customer appeal. But its own internal forecasts, as well as the swelling of its share price, are based on the expectation that the future will unspool in an orderly fashion identical to the recent past. That’s a dangerous assumption to make – for several reasons:

Economists say that both the residential and commercial markets in Hong Kong will be hurt by the same factors: slower growth in China, the depreciation of the renminbi, a crackdown on corruption on the mainland, and predictions that the US’s low interest-rate environment is due to end. However, government cooling measures introduced in 2012 to reduce speculative investment in Hong Kong property are an additional damper on the residential sector.
你可能觉得我们对于列清单的爱好是从“十诫”继承而来,但安伯托·艾柯( Umberto Eco)的说法却正相反,“清单是文化的起源”,他写过一本书,《无限的清单》(The Infinity of Lists),书中在讨论自己熟悉的东西时这样说道。而且,文化希望“让无限变得可以理解”,并且“创造秩序——不是永远如此,但通常都是这样”,所以才有了荷马在《伊利亚特》中的人名清单,以及你冰箱上贴着的,永远做不完的家务清单。“我们喜欢清单,因为我们不想死,”艾柯还说,这可能是对“清单体”(listicle)的最佳解释了。
