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 南京2020年蓝天率要达72% 新型环保涂料将得到重用.
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.

The People’s Bank of China has long intervened in foreign-exchange markets to hedge against excessive volatility. Since August, however, such intervention has expanded from the domestic spot market, which covers daily transactions, to include the offshore renminbi market in Hong Kong, as well as both onshore and offshore futures markets, traders say.

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.
Strachan says that he believes that the IP-BOX uses the same method employed by the FBI to unlock the iPhone 5c used by Syed Farook, without Apple's help. The FBI is now offering to help other law enforcement agencies seeking to unlock an iPhone, iPad or Apple iPod touch. Apple is trying to discover how the FBI unlocked the phone so that it can issue a software update to close the vulnerability.
World's Most International Universities Ranking 2016 by The Times Higher Education included 200 universities from 28 countries. It employed indicators such as the proportion of international staff, the number of international students and research papers published with at least one co-author from another country of each institution.
Alfonso Cuaron and his colleagues, most notably the cinematographer Emmanuel Lubezki, the production designer Andy Nicholson and the filmmaker's co-writer, Jonas Cuaron, have made a motion picture that expands the way motion pictures will be made. Readers with an interest in technology can get a sense of their extraordinary achievements from last month's cover story of American Cinematographer, which is available online. But the emotional essence of the film is already known to anyone who has seen it, and has been swept away by it-into the outer space of silence and menace, into an inner space of deep delight.

I like a miniskirt and maxi-dress as much as the next woman; they are, generally, flattering and easy to wear. And there’s no question that seeing them on Megan and Company was a potent reminder.
