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 高端进口家具市场冷热不均 惨淡市场淘出真金.
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.

Suspecting that the water had been mixed with something harmful, Tang reported the incident to the class monitor and teachers.
In the field of the best 85 business schools in Europe, HEC Paris remains in second place behind LBS, while Insead, the international school based in Fontainebleau, France, climbs two places to third.
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:
Sport dominated the trending searches, with Euro 2012 and Olympic tickets showing the biggest rises in interest ahead of Houston and the Duchess of Cambridge.
Mr Yao, 46, is based in the southern Chinese city of Shenzhen and first made his fortune in real estate. But it was his Baoneng Group’s foray into insurance and subsequent raid on Vanke, a cross-city property rival, that fuelled the estimated ninefold increase in his net worth in the space of a year.

It's almost TOO good. Soulful and aching and grand, Adele's theme to Skyfall is stunningly performed, and gives the distinct impression that someone tried to make the ultimate James Bond theme and had the talent to back it up. History and sensuousness have elevated two songs higher than Adele's contribution, at least in our eyes, but not by much.

Similar to quick LinkedIn overhauling, Foss says employers will likely notice if you abruptly go from tweeting cat GIFs and "Game of Thrones" spoilers to posting thoughtful, industry-focused content and participating in job-search Twitter chats. These are generally good moves for your job search, but bad ones for keeping it under wraps, so again, take it slow。
Were you late to work yesterday because you couldn't remember where you put your car keys? Did you completely forget about a coffee date last week with a friend and only remember when you got a text asking, "where are you?" Can you no longer remember the name of your favorite elementary school teacher? Memory problems impact just about everyone to a certain degree, but science suggests you might be able to improve your memory, as well as reduce the likelihood of Alzheimer's and dementia, by engaging in certain activities, eating specific foods, and using certain mnemonic devices.
