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.

几年前,有人发明了一辆会飞的自行车,叫做"Paravelo"。称一辆自行车会飞,并不是开玩笑,而是这辆自行车真的会飞(车头有一个巨大的降落伞)。它在陆地和空中的时速分别为25千米(15英里)和40千米(25英里),可飞至1200米(4000英尺)高空。最棒的地方是什么呢?那就是你不需要有飞行驾照。Paravelo号称世界上第一辆会飞的自行车,但我们必须指出它并不是第一辆会飞的自行车。

"Moreover, most Chinese families only have one child, so many of us return to China because we want to stay close to our family and friends," said a student surnamed Su, who gave up his job in the UK and returned to take care of his mother in China.

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.

排放量去年的增幅比过去十年中2.5%的平均增长率略低,而且排放量增幅之所以下降,很大程度上是由中国经济增长放缓所引起的。中国是世界上最大的温室气体排放国。可能还需要再花一到两年时间,才能弄清楚中国排放量的增长究竟有没有放缓,还是最近数年那种极高的增速仍会持续。

今年3月,福特以16亿美元将沃尔沃卖给中国吉利汽车,从此退出豪华汽车市场。虽然这是一个巨大损失——福特11年前购买沃尔沃这家瑞典汽车制造商花了60亿美元——但2009年福特实现了27亿美元的利润,是2005年以来首次盈利。受惠于“旧车换现金”计划(更不要说丰田的加速器问题了),今年2月福特重新占据了美国最大汽车制造商的宝座。这也是为什么福特首席执行官阿兰?穆拉里能够将目光投向国外,如印度这样的大市场,在印度推出了紧凑车型Figo。

3.Pay no attention to those bow-tied etiquette experts you sometimes see on CNN International, telling you how to behave while in Britain. These people are generally of dubious provenance, normally live in California and tend to peddle advice that is either irrelevant or out of date. For example, they will often say that Britons love queuing and are so fond of apologising that they will often say "sorry" even when something isn't their fault. In reality, Britons are just as likely to jump to the front of a queue and then punch the person behind them for coughing. It all depends on how muggy it is.
