LONDON, June 7, 2012 (Reuters) — Parasitic mites have turbo-charged the spread of a virus responsible for a rise in honey bee deaths around the world, scientists said on Thursday. Bee populations have been falling rapidly in many countries, fuelled by a phenomenon known as colony collapse disorder. Its cause is unclear but the Varroa mite is a prime suspect, since it spreads viruses while feeding on hemolymph, or bee's "blood". To clarify the link between mites and viruses, a team led by Stephen Martin of Britain's University of Sheffield studied the impact of Varroa in Hawaii, which the mites have only recently invaded. They found the arrival of Varroa increased ...

ScienceDaily (June 4, 2012) — A new Purdue University-developed process for creating biofuels has shown potential to be cost-effective for production scale, opening the door for moving beyond the laboratory setting. A Purdue economic analysis shows that the cost of the thermo-chemical H2Bioil method is competitive when crude oil is about $100 per barrel when using certain energy methods to create hydrogen needed for the process. If a federal carbon tax were implemented, the biofuel would become even more economical. H2Bioil is created when biomass, such as switchgrass or corn stover, is heated rapidly to about 500 degrees Celcius in the presence of pressurized hydrogen. Resulting ...

The Peak Oil Crisis: The Edisonian Approach By Tom Whipple Wednesday, May 30 2012 12:50:29 PM While waiting to see if Greece leaves the Eurozone, Spain collapses, and the Iranians can get their act together, it is a good time to discuss some of the recent developments on the Low Energy Nuclear Reactions (LENR) front. There is still no definitive word on whether commercial scale production of cheap and clean energy will be available in time to save us from unaffordable fossil fuels, global warming, economic collapse and whatever else seems destined to make life on earth rather uncomfortable, but claims of progress and circumstantial evidence that the phenomenon is for real continues to ...

Digital Divide 2.0 Remember the worrying over “the digital divide”? During the “concern’s” heyday, I was more than a tad skeptical, as were many others. There’s only so much hand-wringing that a balanced, working person can stand. Now we learn that all the yammering “inspired many efforts to get the latest computing tools into the hands of all Americans, particularly low-income families.” I’m not aware of any government programs to accomplish this, but then I don’t follow the handouts economy as closely as I could. But I do know that some charities got involved, putting computers into rural libraries and computer centers, for instance. (The ...

He says private drone use is more worrisome. That's because he's never adequately understood the need to restrain the state. Reuters As a Bush Administration lawyer, John Yoo employed flawed legal reasoning to facilitate torture and a view of executive power that would make the U.S. Constitution worthless if it were widely adopted. Despite his history of caring more about checks and balances when a Democrat is in the White House, he's been mostly comfortable with the excesses of the Obama era. And a recent item he published at Ricochet is yet another example of why he can't be trusted on questions concerning the federal government and the importance of restraining it to ...

The Department of Energy will spend $452 million—with a match from industry—over the next five years to guide two small modular reactor designs through the nuclear regulatory process by 2022. But cheap natural gas could freeze even small nuclear plants out of the energy market well beyond that date. DOE accepted bids through Monday for companies to participate in the Small Modular Reactor program. A number of reactor manufacturers submitted bids, including NuScale Power and a collaboration that includes Westinghouse and General Dynamic. “This would allow SMR technology to overcome the hurdle of NRC certification – the ‘gold standard’ of the ...
