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 北京东城首开居家养老共享厨房.
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.
Accepting the award, he enthused: 'First off, I want to start off by saying that I'm not really sure how I got this because I've had my album out a few years, but I've got one coming,' before thanking his fans and MTV.

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 Harvard article suggests that protecting the brain with a heart-healthy diet could be the key to warding off dementia and keeping your memory intact well into your golden years. Some studies have suggested certain foods have a positive impact on memory, but no study thus far has revealed the existence of a miracle food. The idea that a heart-healthy diet could also prove beneficial to the brain and memory has become popular with doctors studying Alzheimer's disease and dementia. Some of the risk factors associated with heart disease are similar to those associated with dementia and Alzheimer's. Foods recommended for a heart-healthy diet include fruits, vegetables, and whole-grain bread, as well as beans, nuts, and olive oil. If you can't use every one of these 10 scientific secrets to a perfect memory, a healthy diet might help you avoid losing it!

The number was 34 percent higher during the same period last year, the report said.
