ScienceDaily (Oct. 19, 2012) — New neuroscience research is confirming an old adage about the power of a handshake: strangers do form a better impression of those who proffer their hand in greeting. Share This: A firm, friendly handshake has long been recommended in the business world as a way to make a good first impression, and the greeting is thought to date to ancient times as a way of showing a stranger you had no weapons. Now, a paper published online and for the December print issue of the Journal of Cognitive Neuroscience on a study of the neural correlates of a handshake is giving insight into just how important the practice is to the evaluations we make of subsequent ...

London: A small British company has developed a way to create petrol from air and water, technology it hopes may one day contribute to large-scale production of green fuels. Engineers at Air Fuel Synthesis (AFS) in Teeside, northern England, say they have produced 5 litres of synthetic petrol over a period of three months. The technique involves extracting carbon dioxide from air and hydrogen from water, and combining them in a reactor with a catalyst to make methanol. The methanol is then converted into petrol. By using renewable energy to power the process, it is possible to create carbon-neutral fuel that can be used in an identical way to standard petrol, scientists behind the ...

A typical operating theatre Experts say it can be difficult to upgrade old software on medical devices due to regulatory restrictions High-risk medical technology has been found to be infected by computer viruses and malware, health and security experts have said. They fear that the virus infections could become so severe that a patient may end up getting harmed. Out-dated computer systems which were not able to be changed were to blame for the vulnerabilities, the experts said. One US hospital is said to be deleting viruses from up to two machines a week. The warnings were given as part of a panel discussion in Washington DC, as reported by Technology Review from the Massachusetts ...

ScienceDaily (Oct. 16, 2012) — European astronomers have discovered a planet with about the mass of Earth orbiting a star in the Alpha Centauri system -- the nearest to Earth. It is also the lightest exoplanet ever discovered around a star like the Sun. The planet was detected using the HARPS instrument on the 3.6-metre telescope at ESO's La Silla Observatory in Chile. The results will appear online in the journal Nature on Oct. 17, 2012. Alpha Centauri is one of the brightest stars in the southern skies and is the nearest stellar system to our Solar System -- only 4.3 light-years away. It is actually a triple star -- a system consisting of two stars similar to the Sun orbiting ...

The figures reveal that from the beginning of 1997 until August 2012 there was no discernible rise in aggregate global temperatures This means that the ‘pause’ in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996 The world stopped getting warmer almost 16 years ago, according to new data released last week. The figures, which have triggered debate among climate scientists, reveal that from the beginning of 1997 until August 2012, there was no discernible rise in aggregate global temperatures. This means that the ‘plateau’ or ‘pause’ in global warming has now lasted for about the same time as ...

Sightings of ball lightning have been made for centuries around the world – usually the size of a grapefruit and lasting up to twenty seconds – but no explanation of how it occurs has been universally accepted by science. In a paper published in the Journal of Geophysical Research Atmospheres entitled "The Birth of Ball Lightning" CSIRO and Australia National University scientists present a new mathematical theory which explains how and why it occurs. The new theory focuses on how ball lightning occurs in houses and aeroplanes – and how it can pass through glass. Previous competing theories have cited microwave radiation from thunderclouds, oxidising aerosols, ...

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 ...

Could Lightning Strikes Be Used to Break Down Rubble Into Useful Components of Cement and Aggregate?
Post Date: 2012-10-07 23:56:44 by Tatarewicz
2 Comments
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 ...

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 ...
