unemployment and IT
The future of work in America September 4, 2012 [image: 800px-Cubicle_land]Technology and the Web are destroying far more jobs than they create. We will need to develop a “Third Way” based on community rather than the Market or the State to adapt to this reality, novelist and economic commentator Charles Hugh Smith writes on Business Insider. “The Internet is destroying vast income streams that once …more…
Wireless power system
Wireless power system replaces batteries in implants A breakthrough for miniaturizing implanted devices September 5, 2012 Wireless power transmission to a device in the human heart. Red indicates greatest power; blue is least. (Credit: John Ho, Stanford Engineering) Stanford University engineers have demonstrated the feasibility of a super-small, implantable cardiac device that gets its power from radio waves transmitted from a small transmitter on the surface of the body. This is an impressive achievement that may lead to replacing bulky batteries in implants. That means the implant... mais »

Healthcare System Waste
Healthcare System Wasted $750 Billion in 2009, IOM Says Robert Lowes September 6, 2012 — An inefficient, extraordinarily complex, and slow-to-change US healthcare system wasted more than $750 billion in 2009, according to a new studyfrom the Institute of Medicine (IOM) that calls for a drastic overhaul. Excessive administrative costs on the part of insurers explain some of those squandered dollars, but unnecessary and inefficiently delivered services on the part of physicians, hospitals, and other providers account for the lion's share of the $750 billion, said the report, which was ... mais »
Organic?
The Organic Fable Cristóbal Schmal By ROGER COHENPublished: September 6, 2012 3 Comments LONDON — At some point — perhaps it was gazing at a Le Pain Quotidien menu offering an “organic baker’s basket served with organic butter, organic jam and organic spread” as well as seasonally organic orange juice — I found I just could not stomach the “O” word or what it stood for any longer. Organic has long since become an ideology, the romantic back-to-nature obsession of an upper middle class able to afford it and oblivious, in their affluent narcissism, to the challenge of feeding a planet w... mais »

How Fungi Create the Amazon’s Clouds By VERONIQUE GREENWOOD | September 5, 2012 ADALBERTO RIOS LANZ/SEXTO SOL Mist and clouds above the Amazon are formed in part by the vegetation below en you mess with the Amazon rainforest you mess with a lot of things — 2.5 million species of insects, 40,000 species of plants, 1,300 species of birds, and those are only the known ones. The 1.4 billion of acres of thriving, sprawling biology that cover the Amazon help drive the very metabolism of a continent. And now it appears that the rainforest is at least partly responsible for something else: th... mais »
NGC 5033
Uma galáxia de braços abertos Os braços espirais da galáxia são muito abertos, o que é comum. Mas os externos são surpreendentemente grandes, e se estendem por mais de 100 mil anos-luz. O tamanho é semelhante aos braços da Via Láctea, que também é uma galáxia em espiral.A galáxia NGC 5033 tem braços gigantescos, que podemos observar com ricos detalhes nesse fantástico retrato telescópico. Ela está localizada a cerca de 40 milhões de anos-luz da Terra, na constelação de Canes Venatici, os Cães de Caça, no hemisfério celestial norte./.../

Mortality
Why We Die [Interactive] With global life expectancy rising, many causes of death are dropping off. What still fells us? By Katherine Harmon | September 4, 2012 | 5 - Share - Email A baby born in the U.S. this year is likely to live to blow out 78 birthday candles—a far longer average life span than someone born even in the 1960s. Heart disease is still the biggest killer but it, along with fatal infectious diseases and infant mortality have all fallen to much lower levels in the past half century. Researchers are now hard at work tackling the growing afflictions, such as ... mais »

Also known as M42, the nebula's glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1,500 light-years away. The Orion Nebula offers one of the best opportunities to study how stars are born partly because it is the nearest large star-forming region, but also because the nebula's energetic stars have blown away obscuring gas and dust clouds that would otherwise block our v... mais »
Want to Live Longer? Don’t Try Caloric Restriction The latest research on caloric restrictions shows that near-starvation diets may not be the Fountain of Youth By MAIA SZALAVITZ | @maiasz | August 29, 2012 Decades ago, in the 1930s, researchers working with lab rats made an interesting discovery. Animals that had been deprived of food seemed to live longer than rodents that were fed to satisfaction, raising the intriguing idea that maybe near-starvation was a good, rather than bad thing, for health. Follow up studies, particularly in yeast, confirmed the trend and some forward-thin... mais »
