UC Davis 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 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 .

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 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 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.

Prior to this recent testing, which used sensitive gas chromatography/mass spectrometry, researchers were unsure of the historical use of tobacco on the 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.

As a measure of that fall, 10 works have sold at auction for more than $100 million since 2004, and all of them were made by modern or contemporary artists in the past 120 years. Older paintings have seen their value, in relative terms, level off or decline. The trend was plain to see in recent weeks, as London’s auction houses tried to find buyers for their latest tranche of old masters. As has been the case in recent years, there were few works by major names.

Participants in the study were between the ages of 18 and 44 and were asked to run twice – with and without shoes. After completing their quick runs, researchers found that the heart rate and overall run speed of each participant had no effect on memory, but the presence of shoes or bare feet did. The researchers have hypothesized that the need to engage the mind while running barefoot to avoid pebbles or other impediments could have a positive impact on a person's ability to remember things. If you're an adventurous person, you might try taking a barefoot jog around the block before your next test or before you need to remember something important.

BABYLON (Sundance, Thursday) James Nesbitt, recently seen as the obsessed father of a long-vanished child in “The Missing,” shows up here in a very different role: as a calculating old-school police commissioner who hires an American public-relations expert (Brit Marling) to update the image of Scotland Yard. Danny Boyle (“Slumdog Millionaire”) created this satirical drama, which bears some resemblance to Armando Iannucci’s political comedy film “In the Loop.”

There are, of course, complicated contours to 2016’s unusual politics. In Britain, immigrants from South Asia voted heavily to leave the European Union, citing hopes that curtailing European migration might open space for more people from Asia. In the United States, frustration with and alienation from status quo politics have helped drive Mr. Trump’s rise.
