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 名贵木种价格回落 红木家具利润缩水5%-8%.
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.
In this 1998 swashbuckler classic, Antonio Banderas plays the protege of a boring nobleman who moonlights as a masked outlaw, saving the Mexican commoners of California from corrupt leaders. While Zorro might sound like a regular old-timey superhero, the story upon which The Mask of Zorro is based pulls heavily from legends surrounding a real-life desperado named Joaquin Murietta.
?All the Bond actors have been tall. This isn't a coincidence. A man who is five foot six needs to earn $175,000 a year more a year to be as attractive as a man who is six feet tall. A lot of people commented on Daniel Craig's buff physique in Casino Royale. Once again the depiction clicks with the research: muscular men have more one night stands and you can tell how many women a guy has slept with by the size of his arms. That chiseled torso may mean he's a better lover.
Iron Man 3 is the highest-grossing movie of 2013 so far with $1.2 billion. But that’s not enough to put its star, Robert Downey Jr., on top of our list of the top-grossing actors. Dwayne “The Rock” Johnson beat him this year by working more.

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.

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.
While newcomer to the list Ariel Foxman, who was appointed managing editor at Time Inc.’s In Style in September 2008, isn’t a regular on a television show as of yet, his fashion director Hal Rubenstein is now a judge onLifetime’s Blush: The Search for the Next Great Make-up Artist. And Foxman’s publication led the way in number of advertising pages, boasting over 1,000 during the first half of 2009.
Shapley made early theoretical inroads into the subject, using game theory to analyze different matching methods in the 1950s and 1960s. Together with US economist David Gale, he developed a mathematical formula for how 10 men and 10 women could be coupled in a way so that no one would benefit from trading partners. While that may have had little impact on marriages and divorces, the algorithm they developed has been used to better understand many different markets.

If managers suspect you're looking elsewhere, your LinkedIn profile is often the first place they'll snoop, says Jenny Foss, founder of the career blog JobJenny.com and author of "Ridiculously Awesome Job Search Kit." "It's where a lot of people tend to get busted," she adds。
Domestically, an increasingly active middle class is generating pressure for more accountable governance. Mounting inequalities have nurtured a sense of injustice; 200m migrant workers remain second-class citizens and corruption is worsening. Tackling these problems is urgent, but China's economic successes have fostered an unwarranted self-confidence. Instead, motivated by the Arab spring, the system has moved aggressively to contain any social discontent that might spark more politically sensitive movements.
