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 中安民生“以房养老”骗局：涉非法集资 88人被刑拘.
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.
The U.S. Veterans Day holiday also coincides with other World War One-era holidays around the world, including Remembrance Day in Britain and the Commonwealth nations of Australia and Canada.
In 2016, we've seen a whole lot of new gadgets join the Internet of Things (unfortunately, we've also seen them harnessed by hackers to bring downhuge swaths of the internet). From appliances to clothing, companies really want to sell you the tech that'll make your life "smarter," but sometimes it just makes it slower and dumber. Let's look back on some of the most ridiculous and useless internet-connected gadgets that were produced in the past 12 months.
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.
Sounds like Taylor Swift—but, in fact, it’s her frequent competitor, Katy Perry. Largely because of her Prismatic World Tour, which is now winding down, Perry pulled in $135 million this year. She grossed more than $2 million per city over the course of 126 shows in our scoring period, and added to her total through deals with Coty, Claire’s and Covergirl.
在针对已拥有金融业工作经验的学员开设的金融课程的排行榜上，伦敦商学院(London Business School)重新夺回在2011年至2015年占据的冠军宝座，同时英国剑桥大学(University of Cambridge)佳奇管理学院(Judge Business School)跌回第二名。
从一开始，社交网络就被有效地隔离在互联网之外。比如，Facebook的海量内容通常不会显示在谷歌( Google )搜索结果之中。但是否非得是这种情形？比方说，Twitter搜索结果自动出现在一个标准的谷歌搜索显示页面，岂不是更方便？再比如，当你搜索Yelp时，为什么关于某家餐厅的最新Twitter消息没有显现出来呢？由于利益相悖，不同社交网络往往把各自的内容封锁在专利保护墙之内，但也有不少工具致力于创造性地弥合这道鸿沟。需要说明的是，本文作者的公司已经开发出了这样一种工具。
Here are five things consumers and investors can count on (probably) in 2015:
It is the first time since 2001 that an athlete other than Mayweather Jnr or golfer Tiger Woods topped the earning league.
If you have been out of work for a long time, it may be time to consider taking a job you wouldn't have looked at before.
The year’s most compelling makeup and hair designs have been almost characters themselves (and are certainly more dynamic than some of those who appear on-screen). But while physical features are obvious right away, they can also give shape and nuance to the performances of those who assume them. Sometimes, a big nose creates a window of understanding.
