As PC use declines, infecting them with viruses just won't be as much fun any more. I'd expect to see malware, worms and viruses jump onto tablets and phones. As a consequence, we will all have to start protecting our devices more assiduously.
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 精装房日渐风行 卫浴企业行情悲喜交加.
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.

Companies are always looking to save money, and outsourcing some roles to freelancers can help. Virtual assistants can perform many of the duties of full-time staffers, but with less commitment. These workers could help expand a business, or just encourage things to run more smoothly.
They are beginning to fret far more about insecure contracts, precarious scheduling, low wages and new forms of work via online gig economy platforms such as Uber. The OECD, the influential Paris-based club for rich countries, will publish a “jobs strategy” in 2018 that is likely to put much more emphasis on the quality and inclusiveness of work.
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.
A party of 108 pandas – performers dressed in costumes – descended on London streets today to promote the plight of the cuddly black and white endangered species.
The invulnerable singer broadened into a wider emotional palette – musical too, with guitars and brass lacing through synthetic beats and dub effects. It could recall art-rock godmother Kate Bush (see the single "Green Light").
The new data released yesterday represent the first snapshot of global trade for 2015. But the figures also come amid growing concerns that 2016 is already shaping up to be more fraught with dangers for the global economy than previously expected.
The theory that exercise boosts your intelligence might have some basis in fact according to a study conducted at Georgia Tech. Even if you don't like lifting weights, and the inside of a gym makes you want to run for the nearest doughnut shop, it might take just 20 minutes to enhance your memory, according to the 2014 study. Researchers asked participants to work out for 20 minutes in an intense manner and found that just 20 minutes of activity could help improve "episodic memory" by as much as 10% in young adults.
Aspiring young leaders already place more emphasis on using their influence, rather than trying to exert power through the embedded authority of their position or their assigned title. Many are already gaining leadership experience, not through promotion at established institutions but by running bottom-up movements and voluntary groups, or by shaping their own start-ups.

Finance is one of top school Edhec’s core strengths, both in terms of teaching and research. The school in 2001 established the Edhec-Risk Institute to produce and distribute research on areas such as asset and risk management.
Anna comes from a mob family and her hair, sometimes matched with large sunglasses or wide-lapel Armani trench coats, indicates both a degree of class and no-nonsense power.
It is up to other institutions — notably, Congress, courts and media — and the citizens at large now to do so.
