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 “拍地盖楼”难以为继 房地产走向2.0时代.
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.

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.

在本届戛纳电影节上，女性电影制作人以及相关女性话题曾广受关注成为宣传主题。28年来，戛纳首次以女导演拍摄的电影拉开序幕，伊莎贝拉?罗西里尼(Isabella Rossellini)成为“一种关注”单元评审团主席，莎尔玛?海雅克(Salma Hayek)主持讨论会高调探讨女性角色在电影中的意义。可以讨论的话题有许多，但是真的有何改变吗？数字似乎更能说明问题，主竞赛单元的19部入围作品仅有2部来自女性导演。而后发生的“高跟鞋门”，更有.....面对外界对于影展涉嫌性别歧视的负面消息，艺术总监蒂埃里?弗雷莫(Thierry Frémaux)一点儿反应都没。他只是说，戛纳电影节的举办有着及其不公平的高标准，参展影片不能申请其他诸如威尼斯或柏林电影节。这难道是建议人们去“攻击奥斯卡”？
Latest ECB projections predict the eurozone, which has struggled to grow as strongly as the US or UK, will grow 1.7 per cent in 2016 after hitting 1.5 per cent growth this year as QE bolsters the economy.
Indeed. That's an understated benefit of Philly tanking so hard in recent years: they are so bad it disincentives other clubs from tanking because they'll struggle to be as bad as the Sixers. The Mavericks are in the mix, at least.
The ability of customers to air their dirty laundry to the world via Twitter and Facebook has already changed the customer service game. A 2012 Nielsen survey shows more than half of all customers now turn to social media for redress; meanwhile, some 81% of Twitter users expect a same-day response to questions and complaints. But this fall, things got even more interesting: On Sept. 2, British Airways passenger Hasan Syed spent an estimated $1,000 to purchase several promoted Tweets blasting the company for losing luggage. With paid social media now in customers' arsenal, 2014 may mark the beginning of the end of abysmal customer service at major airlines, credit card companies, banks, and other repeat offenders, characterized by endless phone wait times and those automated "phone trees" (i.e., "Press 1 for English, 2 for Spanish, 3 to waste your entire afternoon on hold ...").
I used to go fishing in Vancouver with my dad until just a few years ago we found the fish full of cancers. And now we hear about animals and plants going extinct every day -- vanishing forever. 以前和我爸爸经常在vancouver钓鱼，但在近几年却发现鱼的身上到处是癌细胞。我们每天都会听说有的动物和植物绝种，那是永远消失的事情。
