    Dec. 7, 2012 – By Steven B. Krivit – Researchers from Toyota Central Research and Development Laboratories performed an independent replication of a Mitsubishi low-energy nuclear reaction transmutation experiment, according to a physicist from Mitsubishi Heavy Industries speaking at the American Nuclear Society LENR session on Nov. 14 in San Diego, Calif. The physicist, Yasuhiro Iwamura, told the ANS audience that the Toyota researchers confirmed that nuclear changes from one element to another took place without the use of high-energy nuclear physics. Most scientists who have not followed this field closely consider such profound claims inconceivable. Toyota used a LENR...

    Cold Fusion Pioneer says LENR is not Fusion Published November 20, 2012. | By jennifer. The man who invented the term “cold fusion” now says that the effect popularly described as cold fusion or low energy nuclear reaction (LENR) is not fusion. Professor Emeritus Steven E. Jones told Sterling D. Allan of Pure Energy Systems that he’s not sure what to call the effect. Jones is the man who came up with the term cold fusion in a Scientific American article in July 1987. Jones was actually researching the phenomenon two full years before Pons and Fleischmann put it on...

    While the year 2011 will be remembered for the remarkable progress in cold fusion achieved in Italy and more particularly by the E-cat reactors of Andrea Rossi, the year 2012 will be remembered for the slow progress of its recognition by the mainstream establishments. Cold fusion, known also as LENR, is a new and safer type of nuclear energy that will rival the currently used unsafe nuclear power. Its advantages are unparalleled: a lack of radioactive waste and byproducts that could be used for a weapon; abundance of fuel (nickel) without the need for mining of radioactive uranium with the...

    A new galaxy class has been identified using observations from ESO’s Very Large Telescope (VLT), the Gemini South telescope, and the Canada-France-Hawaii Telescope (CFHT). Nicknamed “green bean galaxies” because of their unusual appearance, these galaxies glow in the intense light emitted from the surroundings of monster black holes and are amongst the rarest objects in the Universe. Many galaxies have a giant black hole at their center that causes the gas around it to glow. However, in the case of green bean galaxies, the entire galaxy is glowing, not just the centre. These new observations reveal the largest and brightest...

Hoffmann, a computational chemist, and his colleagues Tryve Helgaker, a well-known Norwegian scientist, and co-authors E.I. Tellgren and K. Lange, also working in Norway, have discovered a molecular-level interaction that science had puzzled over for decades but had never seen. That discovery, it turns out, may redefine how science views chemical compound formation. It also answers questions about what goes on in places like white dwarfs, the super dense cores of stars nearing the end...

    A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions based on the fundamental theory of electromagnetism—one of the four fundamental forces in the universe, and harnessed in all electronic devices—may not accurately account for the behavior of atoms in exotic, highly charged states. The theory in question is known as quantum electrodynamics, or QED, which physicists have held in high regard for decades because of its excellent track record describing electromagnetism's effects on matter. In particular, QED has been especially...

    Calling chemistry ‘molecular architecture’ is even more apt than it might seem. There was a time when architectural engineering was largely about getting buildings to stay up: to withstand the stresses and forces that act on them. But today’s architecture is responsive, mutable, adaptive and dynamic. Likewise, chemistry could appear in its first flush to be about making bonds that will last, but today’s chemistry is just as concerned with breaking as it is with making. The dynamic role of weak hydrogen bonding, for example, was illustrated with the discovery of DNA’s structure: to template replication and transcription, the molecule...

    The first steps towards interstellar travel have been taken, but the stars are very far away. Voyager 1 is about 17 light-hours distant from Earth and is traveling with a velocity of 0.006 percent of light speed, meaning it will take about 17,000 years to travel one light-year. Fortunately, the elusive "warp drive" now appears to be evolving past difficulties with new theoretical advances and a NASA test rig under development to measure artificially generated warping of space-time. The warp drive broke away from being a wholly fictional concept in 1994, when physicist Miguel Alcubierre suggested that faster-than-light (FTL) travel...

    LONDON (Reuters) - An international team of astronomers has produced the first map of the universe as it was 11 billion years ago, filling a gap between the Big Bang and the rapid expansion that followed. The study, published in the journal Astronomy & Astrophysics, shows the universe went through a phase roughly three billion years after the Big Bang when expansion actually started to slow, before the force of so-called 'dark energy' kicked in and sent galaxies accelerating away from each other. Much is known about the immediate aftermath of the Big Bang from studies of its afterglow in...

    A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once thought, scientists say. A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre, however subsequent calculations found that such a device would require prohibitive amounts of energy. Now physicists say that adjustments can be made to the proposed warp drive that would...

    Astroboffins have spotted a galaxy cluster that's breaking all the cosmic rules, including coming back to life to spawn stars at an enormous rate. The Phoenix cluster is spewing out the celestial bodies at the highest rate ever observed for the middle of a galaxy cluster; it's the most powerful producer of X-rays of any known cluster; it's one of the most massive of its kind; and the rate of hot gas cooling in the central regions is the largest ever observed. According to the scientists, the cluster is "experiencing a massive starburst" that's forming the equivalent of 740 Suns...

    Scientists at CERN's Large Hadron Collider say they just temporarily created the hottest man-made temperature by colliding two lead ions. According to a source working on the project, the collision sprung loose a plasma "soup" of sub-atomic gluons and quarks at an estimated temperature of 5.5-trillion-degrees Celsius. We won't know just how hot the plasma was for at least a few weeks because the measurements are very delicate and have to be converted to degrees. The consensus seems to be that it will shatter the previous record, which was about 4 trillion degrees.The craziest thing is that this might not...

    A group of physicists at the University of Glasgow is claiming a first: taking photos of entangled photons. In this paper in Nature (hooray for free access!), they explain that their 201 x 201 pixel images captured around 2,500 different entangled quantum states. The entangled photons were imaged using different lens configurations to capture correlations of position and momentum – the characteristics (to shorthand Heisenberg’s uncertainty principle) that mutually preclude excessive knowledge about a given quantum system. From the 100,000 images taken by their setup (pictured*), the scientists say they were able to observe 2,500 states which they described as...

    ANN ARBOR — Astrophysicists have detected, for the first time, the oscillating signal that heralds the last gasps of a star falling victim to a previously dormant supermassive black hole. Led by researchers at the University of Michigan, the team documented the event with the Suzaku and XMM-Newton orbiting X-ray telescopes. These instruments picked up semi-regular blips in the light from a numerically-named galaxy 3.9 billion light years away in the northern constellation Draco the dragon. The blips, scientifically known as “quasiperiodic oscillations,” occurred steadily every 200 seconds, but occasionally disappeared. Such signals have often been detected at smaller black...

    The matter-eating beast at the center of the Milky Way may actually account for Earth's existence and habitabilityAdapted from Gravity’s Engines: How Bubble-Blowing Black Holes Rule Galaxies, Stars, and Life in the Cosmos, by Caleb ScharfOur existence in this place, this microscopic corner of the cosmos, is fleeting. with utter disregard for our wants and needs, nature plays out its grand acts on scales of space and time that are truly hard to grasp. Perhaps all that we can look to for real solace is our endless capacity to ask questions and seek answers about the place we find ourselves...

    In 1964, physicist Peter Higgs of the University of Edinburgh proposed that the infant universe (as in, perhaps a trillionth of a second old) experienced... a phase transition. In much the way an iron bar can suddenly become a magnet when cooled below a certain temperature, space itself acquired a new feature. Instead of a magnetic field, space was filled with a new forcelike field -- since named for Higgs. Other physicists worked out similar scenarios at about the same time, and later work showed how the Higgs phase transition could explain the distinct identities of two of nature's basic...

    Notes from a parallel universe Inside the X-files at the University of California at Berkeley, the line between theory and fantasy, science and supposition, starts to dissolve. The authors of these dissertations are obsessed—and scientists are nearly as obsessed with them Eleven years ago Eugene Sittampalam was sitting in a hotel room on the Libyan coast when he stumbled, as if by fate, on the unified field theory of physics. "I was on an engineering project at the time, with hardly any social life," he says. "I would retire to my room after dinner. I would switch on the radio,...

    Inside the world of Grigory Perelman: the man who solved the world's toughest maths problem proves to be a puzzle himself. He has been called "the cleverest man in the world" and shook academia to its foundations when he announced he had solved a fiendish mathematical problem that had baffled the planet's best brains for a century. Yet Grigory Perelman, a 43-year-old Russian mathematician, has consciously spurned plaudits and wealth to subsist like a hermit. He lives in a 2-bedroom flat with his elderly mother in a dilapidated Soviet-era tower block in St. Petersburg, while neighbours complain that his own...

    Baffled by the expansion of the universe? You're not alone. Even astronomers frequently get it wrong. The expansion of the universe may be the most important fact we have ever discovered about our origins. You would not be reading this article if the universe had not expanded. Human beings would not exist. Cold molecular things such as life-forms and terrestrial planets could not have come into existence unless the universe, starting from a hot big bang, had expanded and cooled. The formation of all the structures in the universe, from galaxies and stars to planets and Scientific American articles, has...
