A microbiologist who supervised the work of accused anthrax killer Bruce E. Ivins explained to a National Academy of Sciences panel Thursday why the arithmetic of growing anthrax didn't add up to Ivins' mailing deadly spores in fall 2001. "Impossible," said Dr. Henry S. Heine of a scenario in which Ivins, another civilian microbiologist working for the Army, allegedly prepared the anthrax spores at an Army lab at Fort Detrick. Heine told the 16-member panel that Ivins would have had to grow as many as 10 trillion spores, an astronomical amount that couldn't have gone unnoticed by his colleagues. According to FBI calculations, Ivins accomplished this working ...

Don’t talk to aliens, warns Stephen Hawking Hawking has depicted what kinds of alien could be out there Jonathan Leake 5 COMMENTS RECOMMEND? (11) THE aliens are out there and Earth had better watch out, at least according to Stephen Hawking. He has suggested that extraterrestrials are almost certain to exist — but that instead of seeking them out, humanity should be doing all it that can to avoid any contact. The suggestions come in a new documentary series in which Hawking, one of the world’s leading scientists, will set out his latest thinking on some of the universe’s greatest mysteries. Alien life, he will suggest, is almost certain to exist in many other parts of ...

NASA's best-recognized, longest-lived, and most prolific space observatory zooms past a threshold of 20 years of operation this month. On April 24, 1990, the space shuttle and crew of STS-31 were launched to deploy the Hubble Space Telescope into a low Earth orbit. What followed was one of the most remarkable sagas of the space age. Hubble's unprecedented capabilities made it one of the most powerful science instruments ever conceived by humans, and certainly the one most embraced by the public. Hubble discoveries revolutionized nearly all areas of current astronomical research, from planetary science to cosmology. And, its pictures were unmistakably out of this world. At times ...

It may be time for the United Nations' climate-studies scientists to go back to school. A group of 40 auditors -- including scientists and public policy experts from across the globe -- have released a shocking report card on the U.N.'s landmark climate-change research report. And they gave 21 of the report's 44 chapters a grade of "F." The team, recruited by the climate-change skeptics behind the website NoConsensus.org, found that 5,600 of the 18,500 sources in the Intergovernmental Panel on Climate Change's ...
Virus modified to split water - energy sourse
Post Date: 2010-04-19 07:20:04 by Tatarewicz

PhysOrg.com) -- A team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth. In this case, the team used a modified virus as a kind of biological scaffold that can assemble the nanoscale components needed to split a water molecule into hydrogen and oxygen atoms. Splitting water is one way to solve the basic problem of solar energy: It's only available when the sun shines. By using sunlight to make hydrogen from water, the hydrogen can then be stored and used at any time to generate electricity using a fuel cell, or to make liquid fuels (or be used directly) for cars and ...
Coldest weather in 30 years marks the start of a series of extreme winters

After enduring the coldest winter for 30 years, you might have been hoping for some respite from the cold weather. However, scientists are now warning that Britain can expect to endure a series of extreme winters - the like of which have not seen for more than 300 years. Researchers have found that low solar activity - marked by a decrease in the sun's magnetic field - influences the weather conditions across northern Europe. The last time the sun showed similar behaviour, between 1650 and 1700, temperatures dropped so low that Londoners were able to skate and hold fairs on the iced-over River Thames. According to a study published today, we are moving into "an era of low ...

Periods of low sunspot activity are associated with changes in the winds that tear though the upper atmosphere, bringing unusually cold winters to northern Europe, a new study finds. The study, published today in Environmental Research Letters1, analysed 350 years of temperature data recorded in central England since 1659, comparing it to astronomical observations of sunspots. The research team, led by Mike Lockwood, a solar-terrestrial physicist at the University of Reading, UK, found that after allowing for global climate change, European winters tended to be 0.5 °C colder than average during low-solar-activity years. The effect is pronounced enough, he says, that the winter of 2009 ...

Who Cares About Global Warming? Jackie Gingrich Cushman Thursday, April 15, 2010 In 1971, I joined my parents and older sister in the second annual Earth Day by picking up litter in Carrollton, Ga. Dozens of us turned out in jeans and sneakers on that sunny April day, walking along the side of the road, picking up trash, putting it into garbage bags. The most memorable piece of trash we picked up was a toilet seat. Why someone had thrown it out on the side of the road, I have no idea, but when we were done, it was gone. After we filled each bag, we tied a knot in the top and left it to be picked up by a truck. At the end of the day, I looked back and saw the roadside, once covered with ...

CHICAGO – A nurse may soon be your doctor. With a looming shortage of primary care doctors, 28 states are considering expanding the authority of nurse practitioners. These nurses with advanced degrees want the right to practice without a doctor's watchful eye and to prescribe narcotics. And if they hold a doctorate, they want to be called "Doctor." For years, nurse practitioners have been playing a bigger role in the nation's health care, especially in regions with few doctors. With 32 million more Americans gaining health insurance within a few years, the health care overhaul is putting more money into nurse-managed clinics. Those newly insured patients will be ...

THE decline in the US bee population, first observed in 2006, is continuing, a phenomenon that still baffles researchers and beekeepers. Data from the US Department of Agriculture showed a 29 per cent drop in beehives in 2009, following a 36 per cent decline in 2008 and a 32 per cent fall in 2007. This affected not only honey production but around $15 billion worth of crops that depended on bees for pollination. Scientists call the phenomenon "colony collapse disorder", and it has led to the disappearance of millions of adult bees and beehives and occurred elsewhere in the world, including in Europe. Researchers have looked at viruses, parasites, insecticides, malnutrition and ...
