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 按8月成交速度 上海新房去库存时间仅为4.6个月.
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.
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 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.
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.
Joakim Noah, meanwhile, proved to be so untradeable that he couldn't even generate a rumor.
Shipments of cellphones made by Chinese companies reached 498 million in 2016, accounting for 88.9% of the country's total shipments, according to the report from the China Academy of Information and Communication Technology.
“An employee bragged to all his colleagues that it was his last day, but failed to let his boss or the HR manager know.”
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.
'Don't ever do this again,' she said to herself. 'It's so scary.'
有趣的是，“真诚的问候”(unfeigned regards)又重回我们的视野——人们现在可以在印度服务中心的邮件上见到这一18世纪末的流行语。而更胜一筹的是这个签名，一个周五我收到了一则消息，末尾处写到：“周末好”(weekend well)。我差点将最佳名词使动用法奖也颁给它，不料最后一刻却杀出一匹黑马，一位顾问无意中说了句：“我们能把那件事冷毛巾一下吗？”(Can we cold towel that?)
