Researchers uncover earliest tobacco use in the Pacific Northwest

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.

The PR industry excelled itself with increasingly fancy descriptions for the basic activities of emailing, talking and meeting. Entrants included: “I want to jump on your radar” (a bad idea, as if you jump on radars they break) and “let’s find a time to connect to mutually update”. My favourite came from a PR man named Michael who wrote: “I hope you don’t mind the outreach.” Alas, I do mind. To reach out has always been hateful, but making it a noun, and reversing the word order, does not help. Michael, you’ve won the Communications cup.
1.中国经济。中国是世界上第二大石油消费国,并且已经在2013年底超过美国,成为全球最大液体燃料进口国。对于油价来说,更重要的一点取决于中国石油消费量在今后几年的增长态势。美国能源情报署预计,2020年中国的日均原油消费量将比2012年高出300万桶,约占这段时间内全球新增需求的四分之一。尽管还存在很多不确定因素,但中国经济刚刚送走了令人失望的第四季度。最终,中国2014年全年经济增长率跌至逾25年来的最低点。中国经济能否停止减速,这一点我们难以得知,但它的走势将对2015年的油价产生巨大影响。

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.

So with such a strong South American contingent, where will the main challenge come from ? Well, the big guns from Europe is the obvious answer. And where else could you look for a team of Champions than Spain. Having won the last World Cup, sandwiched between two European Championship triumphs, this is a team that not only knows how to play fantastic football, but that knows how to win. So whilst Messi and Ronaldo get all the annual plaudits and player of the year titles, the likes of Xavi and Iniesta go about winning all the major trophies. So will they be as string this year ? Well, worryingly for the rest of the world, yes. Not only are most of the old guard still there but talented youngsters such as Koke and Thiago Alcantara have joined the ranks. Not only that, but they've managed to grab a prolific striker, Diego Costa, from under the noses of the host nation, with the Atletico Madrid forward opting to play for Spain, rather than the nation of his birth.

“Selling out!” “Pandering to the Americans!” The cries went up immediately when the official selection was announced. The list of directors crossing over to make films in English was a long one including the Italians Matteo Garrone and Paolo Sorrentino, Yorgos Lanthimos of Greece, Norway's Joachim Trier and even Guillaume Nicloux of France, a country whose cultural establishment is highly sensitive to the creeping Anglophone menace. The argument goes that Cannes is supposed to be a haven for world cinema; for English, there is Hollywood. But does it really matter? Films at Cannes in languages other than French or English play with subtitles in both languages – and that's a lot of text to deal with.
