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 集体土地建租赁房需分好蛋糕 保护农民利益.
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.
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.
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.
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.
Maybe not a supernova player, but a good one who could get them right back on solid footing more quickly than these other teams we're discussing. Play out the season, pay off your debt, and move forward without that hanging over your head.

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:

当你听说今年3月份，一个17岁的学生把自己设计的一款软件以3,000万美元卖给雅虎公司(Yahoo! Inc., YHOO)的时候。对于这孩子的形貌，你脑海里或许已勾画出一个搞笑的形象了吧：不用说，肯定是个极客。一个除了一行一行写代码之外对什么也不感兴趣的学霸。一个不敢正眼瞧人还老小声儿嘀咕着什么的神经质。
Wardrobe malfunctions was another common theme. Some hapless interviewees “showed up in sweatpants,” one “was wearing mismatched shoes,” and another “didn’t realize his zipper was down.”
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。
