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 ...

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 ...
Avoiding fracking earthquakes: expensive venture

NEW YORK, Jan. 3, 2012 (Reuters) — With mounting evidence linking hundreds of small earthquakes from Oklahoma to Ohio to the energy industry's growing use of fracking technology, scientists say there is one way to minimize risks of even minor temblors. Only, it costs about $10 million a pop. A thorough seismic survey to assess tracts of rock below where oil and gas drilling fluid is disposed of could help detect quake prone areas. But that would be far more costly than the traditional method of drilling a bore hole, which takes a limited sample of a rock formation but gives no hint of faults lines or plates. The more expensive method will be a hard sell as long as irrefutable ...

A Universe Designed for Life (Chapter 10 of "Human Devolution - A Vedic Alternative To Darwin's Theory" by Michael Cremo)

A Universe Designed for Life The universe itself appears designed for life. Certain fundamental constants of nature, certain ratios between the forces of nature, appear to be very finely tuned. If their numerical values were even slightly different, the universe as we know it would not exist. Stable atoms, stars, and galaxies could not form (Barrow and Tipler 1996, p. 20). And thus, life itself, as we know it, could not exist.The values of the constants and ratios appear to be entirely arbitrary. In other words, as far as scientists today can tell, the values are not determined by any law of nature or property of matter. It is as if the values had been set by chance. But the odds ...

Top ten tech predictions for 2012 … and how to interpret them
Post Date: 2012-01-05 06:41:49 by Tatarewicz

Around this time of year you see plenty of articles (such as this one) reflecting on notable technologies and events of the year now gone. Such pieces will also attempt to predict the events of the year just started. When reading these articles, it’s worth considering how the technologies being described are never taken in isolation. Instead, these technologies always need to be seen in terms of how they interact with and impact our personal and social lives. How technology does this, however, can be subtle and extremely complex. In fact, there is a significant amount of research – past and present – that focuses on why we do or don’t use software and technology. Most ...

ScienceDaily (Jan. 3, 2012) — Mice bred to age too quickly seemed to have sipped from the fountain of youth after scientists at the University of Pittsburgh School of Medicine injected them with stem cell-like progenitor cells derived from the muscle of young, healthy animals. Instead of becoming infirm and dying early as untreated mice did, animals that got the stem/progenitor cells improved their health and lived two to three times longer than expected, according to findings published in the Jan. 3 edition of Nature Communications. Previous research has revealed stem cell dysfunction, such as poor replication and differentiation, in a variety of tissues in old age, but it's not ...
Fly parasite turns honeybees into zom-bees

Some bees leaving their hives, then dying after wandering about in a stupor If deadly viruses and fungi weren't enough, honeybees in North America now must also deal with a fly parasite that causes them to leave their hive and die after wandering about in a zombie-like stupor, a new study shows. Scientists previously found that the parasitic fly, Apocephalus borealis, infects and ultimately kills bumblebees and paper wasps, while the "decapitating fly," an insect in the same genus, implants its eggs in ants, whose heads then pop off after the fly larvae devour the ants' brains and dissolve their connective tissues. Now researchers have discovered honeybees parasitized ...

Japan developing cyber weapon: report Japan has been developing a virus that could track down the source of a cyber attack and neutralise its programme, the daily Yomiuri Shimbun reported Sunday. The weapon is the culmination of a 179 million yen ($2.3 million) three-year project entrusted by the government to technology maker Fujitsu Ltd to develop a virus and equipment to monitor and analyse attacks, the daily said. The United States and China are reported to have put so-called cyber weapons into practical use, Yomiuri said. Japan will have to make legal amendments to use a cyber weapon as it could violate the country's law against the manufacture of a computer virus, the daily said. ...
