INCOMING CME: Active sunspot 1401 erupted yesterday, Jan. 19th around 16:30 UT, producing an M3-class solar flare and a full-halo (coronal mass ejection CME). The Solar and Heliospheric Observatory recorded the cloud expanding almost directly toward Earth: Analysts at the Goddard Space Weather Lab say strong geomagnetic storms are possible when the cloud arrives this weekend. Their animated forecast track predicts an impact on Jan. 21st at 22:30 UT (+/- 7 hrs). Aurora alerts: text, voice. The cloud is also heading for Mars, due to hit the Red Planet on Jan. 24th. NASA's Curiosity rover, en route to Mars now, is equipped to study solar storms and might be able to detect a change in the ...
Mind can control allergic response

You – or more accurately, your brain – has control over how allergic your skin is, suggests new research. A team of neuroscientists have found that if someone has a lesser sense of ownership over a part of their body, their immune system also responds differently to that body part, treating it as 'non-self' rather than 'self'. These findings have direct implications for understanding autoimmune disorders such as multiple sclerosis and a range of neurological and psychiatric conditions characterised by a disrupted sense of ownership over one’s body, such as stroke, schizophrenia, autism, epilepsy, neuropathic pain, anorexia nervosa and bulimia. In two ...

The advance could lead to tiny hard drives able to store 200 to 300 times more information than they can today. The tip of a scanning tunneling microscope precisely assembles atoms onto a surface to make the world's smallest hard drive. Click to enlarge this image. Hard drives could one day be the size of rice grains, powering music players so small they would fit inside your ear. Scientists at IBM and the German Center for Free-Electron Laser Science have built the world's smallest unit of magnetic storage, using just 96 atoms to create one byte of data. Conventional drives require a half a billion atoms for each byte. The advance could lead to tiny hard drives able to store ...
Earth’s acid coming from nature

Satellites showing that nature is responsible for 90 per cent of the earth’s atmospheric acidity shocked researchers from the Belgian Institute for Space Aeronomy, whose findings have just been published in the journal Nature Geoscience. Stunned, the scientists approached a team from the University of Wollongong’s Centre of Atmospheric Chemistry (CAC) to confirm what satellite readings were telling them. By providing data from a ground-based solar Fourier transform spectrometer instrument at the University, CAC used 15-years worth of information to verify the satellite’s story: all existing global models had substantially misjudged the main source of formic acid levels on ...

NEW YORK (Reuters) Jan 16 - From Darwinian evolution to the idea that personality is largely shaped by chance, the favorite theories of the world's most eminent thinkers are as eclectic as science itself. Every January, John Brockman, the impresario and literary agent who presides over the online salon Edge.org, asks his circle of scientists, digerati and humanities scholars to tackle one question. In previous years, they have included "how is the Internet changing the way you think?" and "what is the most important invention in the last 2,000 years?" This year, he posed the open-ended question "what is your favorite deep, elegant or beautiful ...

Space, “the final frontier,” has long been the exclusive domain of the State because they were the only organization that had both the tremendous resources necessary to get there and the willingness to waste those resources with no foreseeable economic purpose. As a child I was enamored with Star Trek, but once I became familiarized with the ideas of liberty it was obvious that the Federation described by Gene Roddenberry was essentially just a fascist military regime that happened to be slightly more egalitarian than all the other fascist military regimes. But recent events seem to indicate that the future of space may be more like Fire Fly, where the frontier is the domain of ...
Internet users 'should check for blackout virus'

The German government says all internet users should check their computers for a virus which could stop them going online from March 8. The “DNS-Changer” program infects up to 33,000 computers in Germany each day, according to authorities who arrested those behind the scheme in November. A “DNS-Changer” infection means a computer connects to a fake version of the Domain Name System – the service which enables access to websites, the Office for Information Technology Security (BSI) said on its website on Wednesday. Rather than connecting to the normal DNS, an infected computer is instead re-routed to websites which criminals have manipulated and use for fraudulent ...

Cheap LED Lighting Races Ahead with OSRAM Breakthrough JANUARY 14, 2012 BY TINA CASEY LEAVE A COMMENT International lighting industry giant OSRAM has just announced a research breakthrough that will make the cost of high-efficiency LED light bulbs sink like a stone. Considering the volume of hay that certain politicians have made this year fighting against LEDs and other new technologies, that should cause more than a few faces to start glowing beet red. After all, who could be against a simple, easy-to-install household device that saves money every time you flip a switch? While OSRAM’s new LEDs still might not become quite cheap as conventional incandescent bulbs, this new ...

Rossi: First E-Cats Will Now Cost $50 per kW January 13, 2012 Andrea Rossi is full of surprises. He recently announced that he would never be undersold by his competitors and said that a domestic E-Cat delivering 10-20 kW of power would cost between $1000-1500 USD. Today he has slashed that price by up to two thirds. In a comment on his JONP site he writes: The big science, after trying to ridiculize us, now has understood that the E- Cat works, so now they are trying to copy and make patents to overcome us, discourage us and trying with this sophysticated way to stop us under a disguise of an indirect vindication. Is a smart move, but they are underevaluating us. I will never stop, ...
Hotter homes produce smarter babies

A hotter home appears to produce babies with better cognitive abilities - but before you turn up the home heater to make your baby brainier, the research was conducted on the Australian lizard Bassiana duperreyi by researchers from the University of Sydney. Many traits in young reptiles are determined by the temperature of the nest, so Joshua Amiel, a PhD student in the School of Biological Sciences, and his supervisor, Professor Rick Shine, looked at how incubation temperature would affect the learning performance of these lizards. Published in the UK's Royal Society journal Biology Letters, the research found that lizard eggs incubated at higher temperatures resulted in baby lizards ...

Mystery of Car Battery's Large Current Solved

ScienceDaily (Dec. 20, 2011) — Chemists have solved the 150 year-old mystery of what gives the lead-acid battery, found under the hood of most cars, its unique ability to deliver a surge of current. Lead-acid batteries are able to deliver the very large currents needed to start a car engine because of the exceptionally high electrical conductivity of the battery anode material, lead dioxide. However, even though this type of battery was invented in 1859, up until now the fundamental reason for the high conductivity of lead dioxide has eluded scientists. A team of researchers from Oxford University, the University of Bath, Trinity College Dublin, and the ISIS neutron spallation ...
Autistic children have a different gut bacteria

The underlying reason autism is often associated with gastrointestinal problems is an unknown, but new results to be published in the online journal mBio® on January 10 reveal that the guts of autistic children differ from other children in at least one important way: many children with autism harbor a type of bacteria in their guts that non-autistic children do not. The study was conducted by Brent Williams and colleagues at the Mailman School of Public Health at Columbia University. Earlier work has revealed that autistic individuals with gastrointestinal symptoms often exhibit inflammation and other abnormalities in their upper and lower intestinal tracts. However, scientists do ...

Comprehensive Picture of the Fate of Oil from Deepwater Horizon Spill
Post Date: 2012-01-11 06:37:02 by Tatarewicz
0 Comments
When combined, the data tell a story about the fate of the oil and gas in the air, on the surface and in the ocean and enabled a new chemistry-based spill rate estimate of an average of 11,130 tons of gas and oil compounds per day -- close to the official average leak rate estimate of about 11,350 tons of gas and oil per day (equal to about 59,200 barrels of liquid oil per day). In total, approximately 4.2 million barrels of oil were released from the well. Ryerson and his colleagues determined that the visible surface slick represented about 15 percent of the total leaked gas and oil; the airborne plume accounted for about another 7 percent. About 36 percent remained in an underwater ...

BEIJING Jan. 10 (Xinhuanet) -- Scientists have found a plant in Brazil using leaves to capture the tiny worms in the soil, according to Monday's Proceedings of the National Academy of Sciences in the U.S. The plant, named Philcoxia, was found in the tropical grassland of Brazil, where the biodiversity is well conserved. As the scientists searching for the answer of why the plant grows the leaves underground, they found the 1.5 millimeters-wide leaves can trap the worms and produce a digestive enzyme to help its roots to absorb the nutrition. Although it is not the first meat-eating plant to be discovered, the finding has still "broaden up our perception about plants," ...

Canadian scientists probing ancient chemical deposits on the shores of a High Arctic lake have shed new light on the greatest mass extinction in Earth history — the "Great Dying" that wiped out about 90 per cent of the planet's species 250 million years ago. Sampling layers of sediment on Nunavut's Axel Heiberg Island that contain fallout from a series of colossal volcanic eruptions in Siberia during that time, researchers with the University of Calgary and Geological Survey of Canada found evidence of enough mercury pollution to have "overwhelmed" marine ecosystems and contributed to the massive global die-off at the end the Permian age.

Waves at the Wedge are legendary for hurling bodysurfers into the air and sweeping tourists off their feet. But the walls of water that rise up at the end of the Balboa Peninsula in Newport Beach also could serve a far more utilitarian purpose: producing electricity. A pair of Newport Beach entrepreneurs have been testing a wave-powered turbine near the famed bodysurfing spot for years and have now approached city officials for permission to set up a more permanent prototype, possibly off one of the city's two piers. But because of strict regulations and high costs, Mark Holmes and David New, partners in Green Wave Energy Corp., say it will be a long time before their generators can ...
