An experiment to recreate the extreme conditions of the centre of the Earth was officially opened on Thursday. The ID24 beam line at the European Synchrotron Radiation Facility (ESRF) will use X-ray beams to subject iron and other materials to extraordinary temperatures and pressures. How the X-rays are absorbed should give insight into the mysterious processes going on at and near the Earth's core. For example, the work could unravel why the Earth's magnetic field can "flip". The Earth's core, some 3,000km (1,900 miles) below sea level, will never be reached directly by scientists. In fact, research continues in an attempt to drill through the Earth's ...
Fossils From Animals And Plants Are Not Necessary For Crude Oil And Natural Gas, Swedish Researchers Find

ScienceDaily (Sep. 10, 2009) — Researchers at the Royal Institute of Technology (KTH) in Stockholm have managed to prove that fossils from animals and plants are not necessary for crude oil and natural gas to be generated. The findings are revolutionary since this means, on the one hand, that it will be much easier to find these sources of energy and, on the other hand, that they can be found all over the globe. “Using our research we can even say where oil could be found in Sweden,” says Vladimir Kutcherov, a professor at the Division of Energy Technology at KTH. Together with two research colleagues, Vladimir Kutcherov has simulated the process involving pressure and heat ...
World has five years to avoid severe warming: IEA

The world has just five years to avoid being trapped in a scenario of perilous climate change and extreme weather events, the International Energy Agency (IEA) warned on Wednesday. On current trends, "rising fossil energy use will lead to irreversible and potentially catastrophic climate change," the IEA concluded in its annual World Energy Outlook report. "The door to 2.0 C is closing," it said, referring to the 2.0 Celsius (3.6 Fahrenheit) cap on global warming widely accepted by scientists and governments as the ceiling for averting unmanageable climate damage. Without further action, by 2017 the total CO2 emissions compatible with the 2.0 C goal will be ...
Thirty Years of Misleading the Public on Iranian Nuclear Capabilities

The Christian Science Monitor has a brilliant timeline up covering warnings of Iranian nuclear weapons capability for over thirty years. According to western intelligence, they’ve pretty much always been on the verge of having the bomb. Below is a summary. 1984: West German intelligence sources say Iran’s production of a bomb “is entering its final stages.” 1992: Israeli parliamentarian Benjamin Netanyahu tells his colleagues that Iran is 3 to 5 years from being able to produce a nuclear weapon. Foreign Minister Shimon Peres tells French TV that Iran was set to have nuclear warheads by 1999. 1995: New York Times reports US and Israeli concerns that ”Iran is much ...

This Brilliant Tool Could Be The Ultimate Safe Computing Environment Updated 31. October 2011 - 10:33 by r.schifreen There are lots of software products around which claim to provide a safe computing environment by preventing malware and viruses from ever accessing your hard disk. If you like the idea of such a product, then here's a great one to try. LPS, as it's called, stands for Lightweight Portable Security. It's actually produced by the US Department of Defense for use by military personnel, but the licence explicitly states that it's also for use by the public. LPS comes in the form of a CD image. Download it, burn it to disc, then reboot your computer. After a ...

Autism and possible intellectual advantages
Post Date: 2011-11-07 01:17:34 by Tatarewicz

I was struck by a commentary published last week in the journal Nature that put forth the idea that autism, when it occurs with high intelligence, provides some individuals with certain intellectual advantages over those who do not have the disorder. The commentary author, Dr. Laurent Mottron, a professor of psychiatry and autism researcher at the University of Montreal, bases his conclusions on his own research as well as his experience working with an autistic researcher in his lab and several autistic research assistants. “Everyone knows stories of autistics with extraordinary savant abilities. None of my lab members is a savant,’’ Mottron wrote. “They are ...

If you like puzzles you might try to figure this one out. If you install a Yahoo toolbar into Mozilla’s Firefox you’ll discover that it hijacks Firefox’s new tab page. If you click the new tab button on Firefox you should get a blank and untitled page. But once you’ve installed the Yahoo toolbar instead of a blank page you’ll find that a new tab defaults to Yahoo’s search page. This appears to be part of Firefox forever, until the end of recorded time, or at least until you figure out how to get rid of it. You can disable the Yahoo toolbar – no luck. A new tab still goes to Yahoo search. You can uninstall the Yahoo toolbar. Nope, you’re still going ...

Science gets short shrift in California elementary schools, study finds By Diana Lambert dlambert@sacbee.com Published: Saturday, Nov. 5, 2011 - 11:00 pm | Page 1B Few local educators are surprised by a recent UC Berkeley study that says most California children aren't getting a decent science education. Gretchen Bly, a first-grade teacher at Rancho Cordova Elementary School, generally teaches about 90 minutes of science a week, integrating it into the curriculum as much as possible. "If I had my druthers, we'd do it three or four hours a week," said Bly, who coordinates the school's annual Science Night and other science programs. "With 32 students and less ...

Biggest jump ever seen in global warming gases By SETH BORENSTEIN, AP Thu Nov 3, 7:05 PM EDT WASHINGTON — The global output of heat-trapping carbon dioxide jumped by the biggest amount on record, the U.S. Department of Energy calculated, a sign of how feeble the world's efforts are at slowing man-made global warming. The new figures for 2010 mean that levels of greenhouse gases are higher than the worst case scenario outlined by climate experts just four years ago. "The more we talk about the need to control emissions, the more they are growing," said John Reilly, co-director of MIT's Joint Program on the Science and Policy of Global Change. The world pumped ...

How Albert-László Barabási went from mapping systems to controlling them In 1736 the Swiss mathematician Leonhard Euler ended a debate among the citizens of Königsberg, Prussia, by drawing a graph. The Pregel River divided the city, now Kaliningrad, Russia, into four sections. Seven bridges connected them. Could a person cross all seven without walking over the same one twice? Euler began with a map that cleared away everything—the homes and streets and coffeehouses—irrelevant to the question at hand. Then he translated that map into something even more abstract, a depiction not of a physical place but of an interconnected system. The four sections ...

Never mind the recent spate of satellite showers. An asteroid the size of an aircraft carrier is sailing toward Earth, NASA says. Never fear, however. The space agency says that although next week's flyby of Asteroid 2005 YU55 will bring the rock closer to our home planet than even the moon gets, the asteroid will cruise safely past, leaving in its wake not destruction but data. The agency has already begun using radio waves to scan the 1,300-foot-wide space rock, which will get closest to Earth on Tuesday at about 3:30 p.m. PT. With antennas at its Deep Space Network at Goldstone, Calif., and the Arecibo Planetary Radar Facility in Puerto Rico, NASA hopes to gather a wealth of detail ...
Removing Old Cells Could Extend Human Life

Removal of specific cells that accumulate with age can delay or prevent the onset of age-related disorders, new research suggests. If adapted for humans, this intervention may represent an avenue for treating or delaying age-related diseases and improving healthy lifespan in humans. The old adage "Out with the old and in with the new" could help prevent age-related diseases if applied to certain cells, new research on mice suggests. By removing the body's worn-out cells, called senescent cells, several times during the lifetime of aging-accelerated mice, researchers were able to spare the mice of cataracts, aging skin and muscle loss. "We started treating animals ...

9,000 year old Caucasian mummy found in Nevada [Full Thread]

"> Poster Comment:I suspect that the real reason that the Paiute's do not want the mummy DNA tested is because if it is Caucasoid, as is "Kennewick Man" it provides another data point showing that the Indians were NOT the first inhabitants of the North American Continent. So, the real reason is ethnic politics. Of course there will be narrow parochial assertions made by the "White is Right" crowd as though this proves anything beyond the established evidence suggesting that North America has been inhabited much longer than the Lamestream Archaeologists wish to put forth and by more than one group having disparate geographical origins. Both groups are likely ...

The so-called fine-structure constant, denoted by the symbol ‘alpha' - seems to vary across the Universe. One of the laws of nature may vary across the Universe, according to a study published today in the journal Physical Review Letters. One of the most cherished principles in science - the constancy of physics - may not be true, according to research carried out at the University of New South Wales (UNSW), Swinburne University of Technology and the University of Cambridge. The study found that one of the four known fundamental forces, electromagnetism - measured by the so-called fine-structure constant and denoted by the symbol ‘alpha' - seems to vary across the ...

New research on brain cells could shed more light on neurological diseases, scientists have discovered. Researchers from The Roslin Institute at the University of Edinburgh have found brain cells alter their genetic make-up during a person's lifetime. They have identified genes - known as retrotransposons - responsible for thousands of tiny changes in the DNA of brain tissue. Researchers, whose work is published in the journal Nature, found that the genes were particularly active in areas of the brain linked to cell renewal. By mapping the locations of these genes in the human genome, scientists could identify mutations that impact on brain function and that may cause diseases to ...

With its unique properties, the applications for the metal appeared so vast and revolutionary that, at the time, they bordered science fiction: Half the weight of titanium and twice as stiff Transparent to X-rays Doesn't spark Non-magnetic Doesn't rust Extremely low neutron absorption rate Owning the atomic number 4, it's the lightest metal on the planet next to its unpredictable neighbor, lithium. These scientists knew combining it as an alloy wouldn't just make an extremely light material, but a phenomenally stiff one as well... lighter and stronger than anything they could imagine. The team also observed that beryllium is an excellent absorber and conductor of heat, ...
Scientist who said climate change sceptics had been proved wrong accused of hiding truth by colleague

It was hailed as the scientific study that ended the global warming debate once and for all – the research that, in the words of its director, ‘proved you should not be a sceptic, at least not any longer’. Professor Richard Muller, of Berkeley University in California, and his colleagues from the Berkeley Earth Surface Temperatures project team (BEST) claimed to have shown that the planet has warmed by almost a degree centigrade since 1950 and is warming continually. Published last week ahead of a major United Nations climate summit in Durban, South Africa, next month, their work was cited around the world as irrefutable evidence that only the most stringent measures to ...

In this Friday, Oct. 28, 2011 photo, Richard Muller, left, and his daughter, Elizabeth Muller, hold a globe as they talk about their study on climate at their home in Berkeley, Calif. A new study of Earth’s temperatures going back more than 200 years finds the same old story: It’s gotten hotter in the last 60 years. What’s different is the scientist behind the latest study - Richard Muller. The California physicist was doubtful of what climate scientists have been saying - until he did his own research, partly funded by climate change skeptics. Elizabeth Muller, co-founder and executive director of the Berkeley Earth Surface Temperature Study, ran the study. WASHINGTON ...
