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 人民时评：让居住证安定那些漂泊的心.
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.
《广告狂人》对时装的影响体现在品牌的发展当中，例如香蕉共和国(Banana Republic)就推出了《广告狂人》系列（这个系列是与该剧的服装主管贾妮·布赖恩特[Janie Bryant]联合设计的），而且很多心照不宣的地方在设计中更加随处可见：裁剪和印花，褶边和接缝；它的影响渗入了在秀台上普遍存在的一种鲜明理念：如果你缺乏灵感或者产生了审美怀疑，就去回顾60年代吧。

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.
In a bid to curb capital outflows and ease downward pressure on the renminbi, Chinese regulators have imposed a series of new restrictions on outbound dealmaking in recent months. The new curbs came after outbound investment in non-financial assets surged by 44 per cent in 2016 to a record $170bn.

o Battery power may turn out to be a transition technology. Cost reductions have been slow in coming, and Tesla needs a 30% improvement in order to build the $35,000 Model 3 it has promised for 2017. Toyota’s recent move was eye-opening. It is allowing a battery-supply deal with Tesla to expire and instead will redouble its work on hydrogen fuel cells. The cost of fuel cells is coming down faster than batteries and fuel cell proponents believe drivers will prefer a relatively rapid refuel with hydrogen to waiting hours to recharge their batteries.
