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 公积金贷款释疑：2015年首月月供可能不降反增.
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.
Goldie Hawn’s award for best supporting actress in the 1970 film Cactus Flower rests somewhere altogether more zen – in the “India Room” in which she likes to meditate. Hers isn’t the only award to apparently emit good vibes – Russell Crowe’s award for best actor, which he won for his role as the bang-on-trend, leather miniskirt clad Maximus Decimus Meridius in Ridley Scott’s 2000 film Gladiator, is kept in a chicken coop on the actor’s Australian ranch. Crowe apparently thinks it helps the hens lay bigger eggs.
"The average salary level of employees grew by about 6.3 percent year on year in the first three quarters of last year, while China's annual GDP growth stood at 6.7 percent in 2016, both slowing from a year earlier," Jin added.
The remarks by Recep Tayyip Erdogan come less than 24 hours before Dutch voters go to the polls in a national election that has been coloured by a heated debate about the role of Islam in Dutch society, spurred by anti-Islam candidate Geert Wilders. Mr Wilders’ Freedom party (PVV) is polling second in the race.

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.
Employees of state-owned firms also expressed more satisfaction with their bonuses than those at private companies – and little wonder, as the average payout at the former was Rmb17,318, or about Rmb6,000 more than what their private-sector counterparts could expect.
10. Neuroscientists have discovered a whole new role for the brain's cerebellum. It's long been assumed that the cerebellum functions largely outside the realm of conscious awareness, coordinating basic physical activities like standing and breathing, but it could actually play a key role in shaping human behaviour.
