Dr Alain Carpentier's new artificial heart look very real expect for the colour and texture.The device is designed to be as similar as possible to the human heart The device beats almost exactly like the real thing using electronic sensors to regulate heart rate and blood flow. Developers Carmat now need approval from the French authorities before pushing ahead with clinical trials. Several teams from around the world have been working to develop the perfect artificial heart that could be fitted into the 20,000 patients worldwide unable to receive a life-saving heart transplant because of a shortage of donor organs. The new heart is covered with specially treated tissue to avoid rejection by the body's immune system and the formation of blood clots. However, the power supply for the heart remains a significant hurdle. Carmat, the company founded by Professor Carpentier and Europe's aerospace and defence giant EADS, says the battery could last for between five and 16 hours a...

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.

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 ha...

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...

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. They gain enormous amount of energy as 2 beams of light travel in opposite directions, circling the structure 11,000 times per second. Scientists hope to put under the scanner the existing laws of physics describing the fundamental nature of matter. Giant detectors are placed inside huge caverns to record data. With 600 million collisions taking place per second, there is huge amount of data generated, which will be recorded in special computing system called the Grid. Some of the scien...

Kate McAlpine the 23-year-old Michigan State University graduate and science writer raps about the Large Hadron Collider, the groundbreaking particle accelerator that has been built in a 17-mile circular tunnel at the CERN laboratory near Geneva, Switzerland. A must see on the YouTube.

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 co...
