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.

简言之,无叶风扇就是没有叶片的风扇。它的工作原理是先将空气吸入风扇基座内部,然后通过扇头环形上的洞将空气吹出。这款风扇据说是詹姆斯·戴森发明的,并命名为"气流倍增器"。就像可以飞行的喷气背包一样,无叶风扇被《时代周刊》评为"2009年度伟大发明"之一,同样它也不是世界上第一个无叶风扇。实际上,第一个无叶风扇于1981年被日本的东京芝区电力公司获得专利。尽管东京芝区电力公司的无叶风扇并没有用于生产制造,但詹姆斯的无叶风扇的原始设计与其设计相似,所以专利局拒绝授予詹姆斯这个专利。尽管授予东京芝区电力公司的专利已经过期,但在授予詹姆斯这项新专利之前,专利局需要他提供该设计的创新之处。詹姆斯的经理吉尔·斯密斯并没有否认这两种无叶风扇间的相似性,只是说两者间的差异在于所用"科技"不同。

New employees at the company's Tulsa headquarters have little time to be shy: on their first days, they're seated at desks with a tub of candy. Colleagues often stop by and introduce themselves while grabbing a snack.

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.

But I know your generation, unlike any other generation in the past, is most eager to look at life differently. So as you leave school, I offer you a list of some obvious-yet-vastly-ignored truths that may help you look at life a little differently than just a series of paychecks:
Domain name registrar GoDaddy, which is based in Scottsdale, Ariz., broke ground in May on its new Global Technology Center in Tempe. GoDaddy already employs 2, 600 people in the Greater Phoenix area and the new facility is expected to add 300 more. Other companies expanding in Arizona include Asurion, a leader in technology protection services. They opened a new technical support center in Phoenix and want to fill 500 jobs by the end of the year. Energy provider Direct Energy opened a new call center in Tempe this year and is looking to fill as many as 300 openings.

His first coding effort resulted in an app that played audio snippets from speeches by his idol, Steve Jobs, whose unauthorized biography he'd recently devoured. 'It was rejected by Apple for every reason,' D'Aloisio says now, laughing. 'Copyrighted audio, poor functionality, too simple.' Another early design allowed users to touch a picture of wood, producing a knocking sound. A third transformed a smartphone screen into a treadmill for your fingers. That one earned about $120 in sales on its first day.

The biggest story of the festival had nothing to do with films. It was about shoes. On Tuesday trade magazine Screen reported that a group of women had been denied access to a screening of Todd Haynes' Carol because their footwear – flat shoes with rhinestones – was unsuitable for the red carpet. Further tales came tumbling forth, social media erupted in indignation and soon enough we were soon dealing with a fully fledgedscandale. The Cannes press office rushed out a garbled statement: “Rules have not changed throughout the years (Tuxedo, formal dress for Gala screenings) and there is no specific mention about the height of the women's heels as well as for men's. Thus, in order to make sure that this rule is respected, the festival's hosts and hostesses were reminded of it.” Well, that cleared that up. Perhaps wisely, press screenings are exempt from any dress code: scruffy journalists are free to ascend the Palais' steps in flip flops and trainers.
