Artists Impression of "Inuk" Nuka Godfredsen

Scientists have sequenced the genome of an ancient human for the first time. An international team extracted DNA from 4,000-year-old hair found in Greenland's permafrost. They were able to sequence an impressive 79 percent of the genetic material and shared a thing or two about this ancient Homo sapiens in this week's issue of the journal Nature.

For starters, it's a dude, and they nicknamed him "Inuk." His DNA indicates that his ancestors left Siberia to travel to the new world before the ancestors of current natives of North America did. He also had brown eyes, thick hair, and darker skin.

And, of course, other key traits we were just dying to know: he had dry earwax (common in Asians and Native Americans), a propensity to baldness, and type A+ blood.

He was also inbred. Inbred to the same degree as someone whose parents were first cousins. And, if we are according to an artist's impression from Nature, a fondness for the most fabulous hairstyle in all of human history: the mullet. Go ancient human.

But in all seriousness, this effort shows that with just the tiniest, damaged-by-the-sands-of-time artifact, scientists can now produce a genome almost as good as they do for modern people. And this ability could be an invaluable tool for learning more about how our old, old ancestors lived.

[My Opinion] TOYOTA

Toyota temporarily halts sales of eight models The carmaker took the unprecedented action because the vehicles' gas pedals can get stuck and cause unwanted acceleration. Toyota will also stop making the cars and trucks Monday. http://www.latimes.com/business/la-fi-toyota-sales27-2010jan27,0,5888108,full.story According to press reports, the German automobile company, Volkswagen is likely to take an opportunity which may conquer the automobile field. In the bottom line, TOYOTA company seems to be frustrated by the makeshift way of management. In my personal view, I feel so sorry and sad. Whatever else might be said, TOYOTA is the main company in terms of automobile business. Success comes and gone. I hope TOYOTA will be reformed by this bitter lesson.

[ENVIRONMENT] Big Food vw. Big Insurance

Big Food vs. Big Insurance By MICHAEL POLLANPublished: September 9, 2009 TO listen to President Obama’s speech on Wednesday night, or to just about anyone else in the health care debate, you would think that the biggest problem with health care in America is the system itself — perverse incentives, inefficiencies, unnecessary tests and procedures, lack of competition, and greed. No one disputes that the $2.3 trillion we devote to the health care industry is often spent unwisely, but the fact that the United States spends twice as much per person as most European countries on health care can be substantially explained, as a study released last month says, by our being fatter. Even the most efficient health care system that the administration could hope to devise would still confront a rising tide of chronic disease linked to diet. That’s why our success in bringing health care costs under control ultimately depends on whether Washington can summon the political will to take on ...
