Associated Press/NSIDC, University of Colorado - This handout photo provided by NSIDC, University of Colorado, taken in Oct. 2003, shows the Antarctic sunlight illuminating the surface of the sea ice, intensifying the effect of the fracture lines. The ice goes on seemingly forever in a white pancake-flat landscape, stretching so far it just set a record. And yet in this confounding region of the world, that spreading ice may be a cock- eyed signal of man-made climate change, scientists say. (AP Photo/NSIDC, University of Colorado WASHINGTON (AP) — The ice goes on seemingly forever in a white pancake-flat landscape, stretching farther than ever before. And yet in this confounding ...

Whenever a new technology is created that has the potential to offer more opportunity and freedom to the average human being, we must listen to the "concerns" generated by major industry and governments. With the Internet, we hear the propaganda that what we know to be a level playing field of the free market of ideas is perceived by those in power as a "potential terrorist recruiting source." In this way, there is a full spectrum of excuses that can be employed for overt suppression, or de facto suppression through regulation, which inevitably results in the hoarding of technology by corporations and governments. The latest technology that is increasing its footprint ...

ScienceDaily (Oct. 5, 2012) — Every year several millions of tons of building rubble are produced. An efficient way of recycling concrete -- the building material of the 20th and 21st century -- does not yet exist. Researchers are working on new recycling methods, and with the aid of lightning bolts, they can break down the mixture of cement and aggregate into its components. Whether the Pantheon in Rome or the German concrete canoe regatta, whether ultra-light or decorative: concrete is unbelievably versatile and is the world's most widely used material -- next to water. It is made of cement, water and aggregate, a mixture of stone particles such as gravel or limestone grit in ...

ScienceDaily (Sep. 12, 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 ...

ScienceDaily (Oct. 5, 2012) — A quick pit-stop at the gas station is enough to put a good dent in your wallet. New technology is set to lower the high cost of filling up your car, by enabling combustion engines to consume two to three percent less gas and signifi cantly less oil, while eliminating a step in engine production. An engine without oil will not survive for very long. Pistons need plenty of lubricant in order to be able to move within the cylindrical sleeves in the engine block. Two things are known to raise the resultant level of friction. The first is attributed to distortion of the cylindrical bore hole when the cylinder head is attached, which is known as static ...

Discovery of Gatekeeper Nerve Cells Explains the Effect of Nicotine On Learning and Memory ScienceDaily (Oct. 7, 2012) — Researchers at Uppsala University have, together with Brazilian collaborators, discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can explain our ability to remember and sort information. The discovery of the gatekeeper cells, which are part of a memory network together with several other nerve cells in the hippocampus, reveal new fundamental knowledge about learning and memory. The study is published today in Nature Neuroscience. The hippocampus is an area ...

October 4, 2012 Solar Cataclysms: On Wednesday's show, journalist and science consultant Lawrence E. Joseph discussed how fluctuations in the sun's behavior provoke shifts not only in the climate, but also in our personal lives. He explained why he believes it's time for human beings to stop taking the sun for granted by assuming it will shine with unwavering intensity until it burns out billions of years from now. A landmark report by the National Academy of Sciences called Severe Space Weather Events concluded that if a solar blast hit, such as the ones from 1859 or 1921, "up to 130 million Americans could be without electrical power for months, or years," he ...

LONDON, Oct. 3, 2012 (Reuters) — The discovery by NASA rover Curiosity of evidence that water once flowed on Mars - the most Earth-like planet in the solar system - should intensify interest in what the future could hold for mankind. The only thing stopping Earth having a lifeless environment like Mars is the magnetic field that shields us from deadly solar radiation and helps some animals migrate, and it may be a lot more fragile and febrile than one might think. Scientists say earth's magnetic field is weakening and could all but disappear in as little as 500 years as a precursor to flipping upside down. It has happened before - the geological record suggests the magnetic ...
Eltanin meteor may have led to Ice Age

When a huge meteor collided with Earth about 2.5 million years ago in the southern Pacific Ocean it not only likely generated a massive tsunami but also may have plunged the world into the Ice Ages, a new study suggests. A team of Australian researchers says that because the Eltanin meteor – which was up to two kilometres across - crashed into deep water, most scientists have not adequately considered either its potential for immediate catastrophic impacts on coastlines around the Pacific rim or its capacity to destabilise the entire planet’s climate system. “This is the only known deep-ocean impact event on the planet and it’s largely been forgotten because ...

63,000-Year-Old Modern Human Skull Found in Laos Published: Aug 21st, 2012 Anthropology | By John Shanks According to an international team of anthropologists, an ancient skull collected from a cave in the Annamite Mountains in northern Laos is the oldest modern human fossil found in Southeast Asia. The skull pushes back the clock on modern human migration through the region by as much as 20,000 years and indicates that ancient humans out of Africa left the coast and inhabited diverse habitats much earlier than previously appreciated. The scientists, who found the skull in 2009, were likely the first to dig for ancient bones in Laos since the early 1900s, when a team found 16,000 ...

You are being watched. The control freaks that hold power in the United States have become absolutely obsessed with surveillance. They are constantly attempting to convince the American people that we are all "safer" when virtually everything that we do is watched, monitored, tracked and recorded. Our country is being systematically transformed into a giant surveillance grid far more comprehensive than anything George Orwell ever dreamed of. If you still believe that there is such a thing as "privacy" in this day and age, you are being delusional. Every single piece of electronic communication is monitored and stored. In fact, they know that you are reading this article ...

Buddhist ‘Iron Man’ found by Nazis is from space 26 Sep 2012 | 17:39 BST | Posted by Daniel Cressey A Buddhist statue brought to Germany from Tibet by a Nazi-backed expedition has been confirmed as having an extraterrestrial origin. Known as the ‘iron man’, the 24-cm high sculpture may represent the god Vai[ravaṇa and was likely created from a piece of the Chinga meteorite that was strewn across the border region between Russia and Mongolia between 10,000 and 20,000 years ago, according to Elmar Buchner of the University of Stuttgart, and his colleagues. In a paper published in Metoritics & Planetary Science, the team reports their analysis of the iron, ...

California has become the third state to welcome driverless cars with open arms. Governor Jerry Brown signed a bill into law today that officially legalized self-driving vehicles, following in the footsteps of Nevada and Florida. The signing event was held at the Google complex in Mountain View, Calif. where engineers have been working on driverless car concepts for years and employees routinely use them to commute to and from work. Such vehicles weren't technically illegal to operate before passage of the bill, but Google and others working on similar technology hope that by making their use explicitly legal it will clear up any confusion on the part of law enforcement and limit the ...

ScienceDaily (Sep. 24, 2012) — Europe accounted for two thirds of the world-wide newly installed photovoltaic (PV) capacity in 2011, with 18.5 GW. Its overall PV capacity totalled 52 GW. The yearly electricity produced by PV could power a country with the electricity demand of Austria, which corresponds to 2% of the EU's electricity needs. These are some of the highlights of the 2012 Photovoltaics Status Report published September 24 by the European Commission's Joint Research Centre. The study summarises and evaluates the current activities regarding manufacturing, policies and market implementation world-wide. Over the past ten years, the PV industry grew in Europe by an ...
Two Cheers for Heresy on Global Warming

Climate change is a cycle—of faddish opinions, I first encountered the strong case for global warming in the early 1970s in an Isaac Asimov science column. As an elementary school student, I merely nodded my head, assumed that America’s political leadership would address the danger, and moved on to an explanation of quarks. Even in those days, the subject was hardly new. The Asimov column had originally run in the late 1950s, before I was even born, and the possibility that burning fossil fuels might raise the Earth’s temperature via the “Greenhouse Effect” had already been around for many decades, going back to the late 19th century. Whether it occurred in the ...
