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 房企上半年业绩分化：七成销售上涨 五成净利下滑.
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.
Hartz started Eventbrite, an online ticketing platform, with her now-husband Kevin in 2006. Since its founding, the company has raised $140 million from firms like Sequoia Capital and Tiger Global Management and reached $2 billion in gross ticket sales this September. Entrepreneurship forced Hartz to appreciate candid and collaborative conversations. "I had to learn how to ask for help," she says. "Everyone always thinks it's brave to go out alone, but I think it's even braver to put yourself out there in front of others, and to figure out how to work together."
Canadian schools continue to lose ground. Only three remain in the ranking compared with five last year and all fall about six places.

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.

They will get more creative in 2018, including on non-cash benefits. Bank of America, for example, has just introduced a programme allowing employees of the global banking and markets unit to take a sabbatical — on full pay — for up to six weeks in a year. There are conditions: people must have been with the bank for at least a decade, and can request the time once every five years, to a maximum of three. But in a memo circulated this week, seen by the Financial Times, chief operating officer Tom Montag urged eligible employees to consider it.
