Networking sites boost privacy
2009-12-13 17:24:00 Did you notice that resently Facebook took a step towards opening up parts of its site to outsiders by introducing more options for user’s privacy settings. The changes will make it easier for Facebook’s more than 350 million users to limit who sees their musings, videos, photos and other personal information, but will also give them the opportunity to expose a wider swathe of their information to a broader internet audience. The move comes as internet search engines like Google and Microsoft are showing interest in incorporating the growing trove of user-generated content from social media websites into their search results. Schrage, Facebook Vice President of Global Communications and Public Policy said Facebook users will be greeted with a message on Wednesday presenting them with new options to customise privacy settings and directing them to a new, simplified overview page of all their personal privacy settings.

Paper and Cloth Batteries
2009-12-11 19:09:00 If a team of researchers at Stanford University are to be believed, Batteries made from plain copier paper could make for future energy storage that is truly paper thin.These guys started with off-the-shelf copier paper, painting it with an "ink" made of carbon nanotubes-tiny cylinders of carbon - to collect electric charge..The coated paper is then dipped in lithium-containing solutions and an electrolyte to provide the chemical reaction that generates a battery's electric current.The paper acts to collect the electric charge from the reaction. Using paper in this way could reduce the weight of batteries, typically made with metal current collectors, by 20%.The team's batteries are also capable of releasing their stored energy quickly. That is a valuable characteristic for applications that need quick bursts of energy, such as electric vehicles - although the team has no immediate plans to develop vehicle batteries.The team says that adaptations to the technique in the future cou...

Rydberg Molecule--strange first
2009-04-23 19:29:00 Back in 1934 Enrico Fermi predicted that if another atom were to "find" that lone, wandering electron, it might interact with it but he never imagined that molecules could be formed.Recently Vera Bendkowsky and his team from the University of Stuttgart created such a molucle known as a Rydberg molecule; this is formed through an elusive and extremely weak chemical bond between two atoms.The Rydberg molecules in question were formed from two atoms of rubidium - one a Rydberg atom, and one a "normal" atom.The movement and position of electrons within an atom can be described as orbiting around a central nucleus - with each shell of orbiting electrons further from the centre.A Rydberg atom is special because it has one electron alone in an outermost orbit - very far, in atomic terms, from its nucleus.Unimaginably cold temperatures are needed to create the molecules.At temperatures very close to absolute zero - minus 273C - this "critical distance" of about 100nm (nanometres - 1nm = one...

The Large Hadron Collider experiment has stoped
2008-09-20 18:03:00 CERN announced on Thursday that it had shut down the collider a week ago after a successful start-up that had beams of protons circling in both clockwise and counterclockwise directions in the collider.It was at first thought the failure of an electrical transformer that handles part of the cooling was the problem, CERN said. That transformer was replaced last weekend and the machine was lowered back to operating temperature to prepare for a resumption of operations.But later it turned out to be a much serious problem. A faulty electrical connection between two magnets that stopped superconducting, melted and led to a mechanical failure and let the helium out and this will keep it out of commission for at least two months.

Say No to Bottled Water
2008-09-16 20:57:00 That bottled water is not only hurting your pockets and the environment but also giving you diabetes and heart disease. An ubiquitous ingredient in plastics known as Bisphenol-A or BPA. BPA is the chemical once studied as a synthetic form of estrogen, but more recently known to leach out of some plastic water bottles and baby bottles, and that is found in all kinds of plastic products.A resent JAMA (Journal of American Medical Association) study has found a connection between BPA and diabetes and heart disease in adults. Scientists reviewed the health of 1,455 American adults and found that people with higher concentrations of BPA in their urine were slightly more likely to have heart disease and diabetes.This study was one of the largest BPA studies done in humans; it could only provide convincing circumstantial evidence that, where high levels of BPA lurked, so do diabetes and poor heart health. The study's authors wrote that their work could not definitively prove that BPA had ... More About: Water
The Large Hadron Collider experiment is on
2008-09-10 21:24:00 The first - clockwise - proton beam completed its first circuit of the underground tunnel at just before 0930 GMT. The second - anti-clockwise - proton beam successfully circled the ring after 1400 GMT. The beams have not yet been run continuously. So far, they have been stopped, or "dumped", after just a few circuits.Cern has not yet announced when it plans to carry out the first collisions, but some low-energy collisions could happen in the next few days. This will allow engineers to calibrate instruments, but will not produce data of scientific interest.The vast circular tunnel - the "ring" - which runs under the French-Swiss border contains more than 1,000 cylindrical magnets arranged end-to-end.The magnets are there to steer the proton beam around this 27km-long ring.In order to get both beams to circulate continuously around the LHC, engineers have to "close the orbit". The beams themselves are made up of several "packets" - each about a metre long - containing billions of pro... More About: Experiment
End of the world or unveiling the mysteries of universe
2008-09-10 04:27:00 Tomorrow the Large Hadron Collider is set to be fired up and everybody is wondering will it bring about the end of the world or provide the answers to the beginning of the universe .Built by the European Organization for Nuclear Research -- known by its French acronym CERN ,the Large Hadron Collider (LHC) buried deep underground along the border of Geneva and France is expected to reveal the secrets of Universe . The collider fires particles into accelerator until they almost acquire the speed of light.

What is on your mind?
2008-08-18 04:13:00 The US military is paying scientists to study ways to read people's thoughts. The research could someday lead to a gadget capable of translating the thoughts of soldiers who suffered brain injuries in combat or even stroke patients in hospitals.Armed with a $ 4-million grant from the army, scientists are studying brain signals to try to decipher what a person is thinking and to whom the person wants to direct the message.The project is a collaboration among the researchers at the University of California, Irvine; Carnegie Mellon University; and the University of Maryland. The scientists use brain wave-reading technology known as electroencephalography, which measures the brain's electrical activity through electrodes placed on the scalp.It works like this: volunteers wear an electrode cap and are asked to think of a word chosen by the researchers, who then analyse the brain activity. In the future, scientists hope to develop thought-recognition software that would allow a computer... More About: Mind

Can water remember a thing or two?
2008-07-26 22:59:00 When we think of memory, most of us think of only living things but believe it or not some inanimate things like water can remember a thing or two.Twenty years ago, in the summer of 1988, the science world was rocked by one of the most controversial research papers ever published in the highly-respected journal Nature.According to a charismatic French scientist named Jacques Benveniste, pure water could somehow remember what it had previously contained.Benveniste had started with a substance that caused an allergic reaction, he diluted it over and over again until there was nothing left except water, and then he observed that the pure water still managed to trigger an allergic reaction when it was added to living cells.If the experiment was correct then it would mean rewriting the laws of physics and chemistry.Moreover, the research would have a major impact on the credibility of homeopathy, because it is a form of alternative medicine that relies on remedies made by diluting the ke...

Universe as a Super Hologram
2008-03-25 15:30:00 You may have heard about the startling parallels between recent discoveries in quantum physics and ancient beliefs of Taoism, Buddhism, and Hinduism through Books such as The Tao of Physics by Fritjof Capra in 1975 and The Dancing Wu Li Masters by Gary Zukav’s in 1979.“Holographic Paradigm” is a continuation of this shiny happy alliance with a particular model of the universe that seemed to explain not only puzzling scientific phenomena but psychic experiences as well. The holographic paradigm was so named because of certain very unusual feature of holograms.In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect discovered that under certain circumstances subatomic particles such as electrons are able to instantaneously communicate with each other regardless of the distance separating them. It doesn't matter whether they are 10 feet or 10 billion miles apart.Somehow each particle always seems to know what the other is d... More About: Universe , Super
Google Bomb

Apprently this attack was a result of Google Bomb .A Google bomb (also referred to as a 'link bomb') is Internet slang for a certain kind of attempt to influence the ranking of a given page in results returned by the Google search engine, often with humorous or political intentionsThe process of manipulating the results of Google by placing a link to a single webpage on several domains. The other most famous incident of Google bombing was when around 32 webmasters put the text “miserable failure” on their websites and placed a link under this text to George Bush’s autobiography. Causing this webpage to rank #1 in Google for the search term “miserable failure.”
origin of antimatter surrounding the galactic center
2008-01-24 19:35:00 New research based on the four years of observations from the European Space Agency’s Integral (INTErnational Gamma-Ray Astrophysics Laboratory) satellite may have cleared up one of the most vexing mysteries in our Milky Way: the origin of a giant cloud of antimatter surrounding the galactic center.Integral found that the cloud extends farther on the western side of the galactic center than it does on the eastern side. This imbalance matches the distribution of a population of binary star systems that contain black holes or neutron stars, strongly suggesting that these binaries are churning out at least half of the antimatter, and perhaps all of it.The cloud itself is roughly 10,000 light-years across, and generates the energy of about 10,000 Suns. The cloud shines brightly in gamma rays due to a reaction governed by Einstein’s famous equation E=mc^2. Negatively charged subatomic particles known as electrons collide with their antimatter counterparts, positively charged positron... More About: Center , Galactic , Antimatter , Origin

Making Anti-Matter
2008-01-17 20:32:00 Antimatter is the mirror image of ordinary matter and both should have been created in equal quantities at the birth of the Universe. That everything around is predominantly ordinary matter is therefore a major puzzle.For years researchers have wanted to create significant amounts of antimatter to test the so-called Standard Model, which describes fundamental particles and their interactions. Antimatter is destroyed whenever it collides with matter, turning both into bursts of radiation. Today, the Universe consists of predominantly one form of matter and scientists are not sure why this is so.Physicists say they have mass produced antimatter, a crucial first step towards precision studies of its properties that may help solve one of the greatest mysteries of the Universe.Antihydrogen has been made before, but only a few atoms at a time.

Technology in Massage Chairs
2008-01-17 00:53:00 Every time one visits to a store like Brookstone or The Sharper Image, one is amazed at the range and features of the Massage Chairs they have to offer . Even more amazing is the technology that goes into making these gadgets; I calling them gadgets because they are no more a piece of furniture. Most of them have an in-built computer now and they will follow you instruction as if you working with a masseur.With Robotic motors and rotors inside, you can choose your massage type from Kneading, Rhythmic Pressure, Tapping, Rolling, and Kneading and Tapping together. With options like Airbag and vibration seat massage where seat air bags exert firm lateral pressure at the outer buttocks and upper thigh to stimulate circulation, while vibration massage soothes your tailbone region.If you compare with a $40 or 50 forty minute session with a masseur, it is great investment to go and buy one of these chairs.My thanks to human touch for sponsoring this post.
