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 各陶瓷产区政府频繁“零点出击”查环保.
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.
But because I can’t help but hope that with the end of “Mad Men” comes the end of a period in fashion that has seen designers become trapped in the past to an almost stifling degree. At least the past as it looked in the 1960s (which in the beginning, let us not forget, looked a lot like the late 1950s) and early ’70s.
While D'Aloisio spends 80 percent of his work time retooling and improving Summly (which has already been integrated into Yahoo!'s iPhone app), the other 20 percent is devoted to imagining the expansive challenges he'll take on next. He predicts there will be summarization programs that do for video what Summly does for the written word. He has grand thoughts about using technology to aid learning and would like to help fellow autodidacts while disrupting the old educational models.
Shanghai Pudong International Airport reported the lowest punctuality rate last year. Only 52.4% of flights took off on time, with delays averaging 48 minutes.
It is based on a survey of business schools and another of their alumni who graduated in 2013.
However, this may be balanced by a decline in European and Chinese investment, with the impact of the latter on global trade heightened if China was to engineer a partial switch from investment in resource-heavy construction to forms of infrastructure spending such as water purification that are not very commodity intensive.

The company is hardly alone in its efforts to woo talent of a different sort. Earlier this year Intel announced a collaboration with the Council of Fashion Designers of America, or CFDA, kicking off a partnership with the high-concept retailer Opening Ceremony to design its smart bracelet. Tory Burch partnered with Fitbit to design pendants and bracelets akin to the Shine Tracker by Misfit Wearables. And Apple AAPL -1.03% has tapped a diverse group of people, including former Burberry chief executive Angela Ahrendts (to lead its retail efforts), former Yves Saint Laurent CEO Paul Deneve, and former Nike NKE -0.71% design director Ben Shaffer.

That partly explains why actuaries have the best job in the United States, according to a new survey by CareerCast.com that will be released Tuesday. Biomedical engineer was No. 2 and software engineer, the top job of 2012, came in at No.3. Careers that ranked the lowest included enlisted military personnel, lumberjack and newspaper reporter.
