iPhone Powered By Viruses? Berkeley Scientists Move Closer Image credit: Berkeley Lab Viruses might eventually be able to power the very phone, computer or tablet you're reading this article on. And we're not talking about those digital viruses or infestations - trojans, worms, and whatnot. Scientists at the U.S. Department of Energy's Berkeley Lab have found a way to generate power using human viruses. "In near future, we believe that we can develop personal electric generators. So how does it all work? And that force is critical to the equation. But the scientists are picturing even broader uses. However, this is still a ways out. "We are currently working on enhancing the power output of the virus-based piezoelectric generators," Lee told us. EnvironmentNature & EnvironmentBerkeley Lab
Transition Culture Cost of Solar Energy Plummets - Renewable Energy If you’re thinking about switching to solar energy, now’s the time. Prices have never been lower, and in some areas, PV systems can now produce electricity at a cost that’s competitive with — or even lower than — conventional electricity from coal, nuclear or natural gas. That’s right — the day we’ve all been waiting for has finally arrived. The cost of solar energy rivals electricity produced by much less environmentally friendly sources. What’s more, the cost of solar power will continue to fall while the price of conventional fuels spirals upward. The cost of a residential solar power system has dropped about 40 percent in just the last two years. Families in many major cities are paying 10 to 12 cents per kwh for conventional power, and soon, many in the Midwest will pay up to 15 cents/kwh for conventional power. Rebates that are available from some utilities lower the price even more. Businesses throughout the country receive even more financial incentives.

When LSD Was Legal (And Cary Grant Was Tripping) Forget 420. In honor of the latest lysergic episode of MAD MEN, a look back at the time before LSD was outlawed. In the latest episode of Mad Men Roger Sterling, the silver-haired drunkard rascal of SCDP, attends a high society LSD party. LSD was first synthesized in 1938 by Dr. Everybody knows that the CIA seized on acid as a possible mind control drug, using it in their MKULTRA experiments. But acid wasn't just being used for sinister purposes. Grant swore by the drug. Clare Booth Luce was such a major fan of acid that she got Henry to drop it (she later said it saved their marriage), and he liked it so much he had Life publish a number of laudatory articles about the drug through the 50s and 60s. But of course the strange thing about acid is that it was anything BUT counterculture... until Timothy Leary came along. Even with the Luces as advocates, there was a backlash to LSD. Acid never got a fair shake therapeutically. * some of the experiments were pretty wild.
Petra: Lost City of Stone Deep within the deserts of Jordan lies the ancient city of Petra. Through a narrow gorge it emerges into view, revealing awe-inspiring monuments cut into the surrounding cliffs. What is this astonishing city?

Today archaeologists are discovering clues to Petra's past. In New York, Petra: Lost City of Stone was made possible by Banc of America Securities and Con Edison.
