    Scientists have recreated a temperature not seen since the first microsecond of the birth of the universe and found that the event did not unfold quite the way they expected, according to a recent paper in Physical Review Letters. The interaction of energy, matter, and the strong nuclear force in the ultra-hot experiments conducted at the Relativistic Heavy Ion Collider (RHIC) was thought to be well understood, but a lengthy investigation has revealed that physicists are missing something in their model of how the universe works. "It's the things you weren't expecting that are really trying to tell you something...

    stronomers have gazed out at the universe for centuries, asking why it is the way it is. But lately a growing number of them are dreaming of universes that never were and asking, why not? Why, they ask, do we live in 3 dimensions of space and not 2, 10 or 25? Why is a light ray so fast and a whisper so slow? Why are atoms so tiny and stars so big? Why is the universe so old? Does it have to be that way, or are there places, other universes, where things are different? Once upon a time...

    Exclusive from New Scientist Hidden extra dimensions are causing measurements of the strength of gravity at different locations on Earth to be affected by the planet's magnetic field, French researchers say. This is a controversial claim because no one has ever provided experimental evidence to support either the existence of extra dimensions or any interaction between gravity and electromagnetism. But lab measurements of Newton's gravitational constant G suggest that both are real. Newton's constant, which describes the strength of the gravitational pull that bodies exert on each other, is the most poorly determined of the constants of nature. The two...

    Scientists claim antimatter breakthrough Scientists have announced the first large-scale production of antimatter. A team based at the European Organisation for Nuclear Research in Geneva say they have developed a large amount of the substance. Antimatter is a reverse form of ordinary matter. When the two kinds of matter meet they annihilate each other in an enormous burst of energy. It's this process which provides the power source for Starship Enterprise in its film and TV space adventures. Physicists have made only very small quantities of antimatter before. But the CERN team say they have made at least 50,000 atoms...

    The recent discovery that the universe is expanding at an ever-increasing rate has led many astronomers to forecast a dark and lonely future for our galaxy. According to some predictions, the rapidly accelerating universe will cause all galaxies to run away from each other until they are no longer visible. In this widely accepted scenario, our own Milky Way will become an isolated island adrift in a sea of totally black space 150 billion years from now. But two new studies by Stanford University cosmologists suggest that it may be time to rethink this popular view of a "runaway universe."...

    Electric signals can be transmitted at least four times faster than the speed of light using only basic equipment that would be found in virtually any college science department. Scientists have sent light signals at faster-than-light speeds over the distances of a few metres for the last two decades - but only with the aid of complicated, expensive equipment. Now physicists at Middle Tennessee State University have broken that speed limit over distances of nearly 120 metres, using off-the-shelf equipment costing just $500. Jeremy Munday and Bill Robertson made a 120-metre-long cable by alternating six- to eight-metre-long lengths of two...

    Lasers now work at new wavelengths FROM a human point of view, the terahertz frequencies are a curiously barren region of the electromagnetic spectrum. They lie, unexploited, between microwaves at long wavelengths and infra-red at short. They are neglected because no one has developed a convenient source of terahertz radiation. Not yet, anyway. But a laser unveiled by Alessandro Tredicucci of the Scuola Normale Superiore in Pisa, Italy, at the recent International Conference on the Physics of Semiconductors, in Edinburgh, lights the way to the future. Research into terahertz sources has been driven hard by demand from industry. Terahertz frequencies...

But it doesn't mean E=mc2 will be consigned to the dustbin, writes David Wroe. In October, 1971, American physicists took four super-accurate atomic clocks, kept two on the ground and put two on commercial jets flying at 1000 kmh in opposite directions around Earth. When the planes landed, the scientists found what they were hoping for: The clocks on the high-speed journeys were ticking a few billionths of a second behind their stationary friends. Motion,...

    If the speed of light can slow down, as new findings suggest, scientists may have to think again about some other laws of nature. John Webb writes. Is it outrageous to ask whether the laws of nature have remained the same since the Big Bang created our universe about 14 billion years ago? The great British physicist, Paul Dirac, didn't think so when he suggested the idea in 1927. And he still thought that way when he lectured on the topic at the University of NSW in 1975. However, the reasons for asking the same question today are very different...

    Australian researchers have experimentally shown that microscopic systems (a nano-machine) may spontaneously become more orderly for short periods of time--a development that would be tantamount to violating the second law of thermodynamics, if it happened in a larger system. Don't worry, nature still rigorously enforces the venerable second law in macroscopic systems, but engineers will want to keep limits to the second law in mind when designing nanoscale machines. The new experiment also potentially has important ramifications for an understanding of the mechanics of life on the scale of microbes and cells. There are numerous ways to summarize the second...

    Pairs of photons linked by the weird quantum effect of entanglement can pass through sheets of metal without the entanglement being destroyed. The finding means the quantum linking of particles is far more robust than scientists thought and could help them develop new ways of making quantum computers. Scientists think quantum computers could be hugely powerful because of their ability to perform many calculations at once, instead of doing one after another like regular computers. When photons are entangled, the physical properties of one are intimately linked to the other. Measuring the properties of one will instantly tell you the...

Now a microscopic tungsten lattice — in effect, a tungsten filament fabricated with an internal crystalline pattern — developed at the Department of Energy’s Sandia National Laboratories has been shown to have potential to transmute the majority of this wasted infrared energy (commonly called heat) into the frequencies of visible light. This would raise the efficiency of an incandescent electric bulb from 5 percent to greater than 60...

    The Chandra orbiting X-ray telescope has found two bizarre objects that may form a new star class and are perhaps filled with a new form of matter --findings that may challenge fundamental theories of particle physics and astronomy. The pulsar in 3C58, shown in two magnifications, suggests that the matter in this collapsed star is even denser than nuclear matter, the most dense matter found on Earth. Observations of 3C58, the remnant of a supernova noted on Earth in AD 1181, reveal that the pulsar in the core has a temperature much lower than expected. This suggests that an...

    Scientists have reported that by bombarding a liquid with sound they were able to produce nuclear fusion in a tabletop apparatus. But their colleagues doubt it. Donald Kennedy, editor of the prestigious journal Science, knew he was in for a row if he published the paper. It’s not that the work was shoddy or came out of left field. On the contrary, the experiments had been performed with great care by well-respected senior scientists at Oak Ridge National Laboratory (ORNL), Rensselaer Polytechnic Institute (RPI) and the Russian Academy of Sciences. But what the authors were claiming was just so extraordinary:...

    An endangered monkey has given scientists new insights into evolution. The leaf-eating douc langur, native to East and Southeast Asia, has a quot;duplicatedquot; gene that started as an extra copy of a gene for a particular enzyme but mutated into a gene for another enzyme with a different purpose. By recreating the gene's path from one enzyme to the other, scientists have addressed an important debate over how natural selection shapes such duplications. Throughout evolutionary history, extra copies of genes have popped up spontaneously in the genomes of many organisms. This gene duplication is thought to be a major source...

    Research could have weapons implicationsBy Frank Munger, News-Sentinel senior writer OAK RIDGE - If bubble fusion works, will a bubble bomb be far behind?Rusi Taleyarkhan, lead scientist on the Oak Ridge research project, acknowledged this week that his work with collapsing bubbles is funded by the Defense Advanced Research Projects Agency - the central research arm of the Defense Department - because of its potential military applications. "The energy density of a reaction such as this is about a million times more than any known conventional explosive," Taleyarkhan said. "So if you can tap this and make it work, you've ...

    Table-top fusion Here we go again Mar 7th 2002 From The Economist print editionIs the world about to witness a repetition of the cold-fusion fiasco? AS PARENTS scare their children with stories of ghosts and ogres, so professors scare their students with stories of Pons and Fleischmann. In 1989 Stanley Pons and Martin Fleischmann, then researchers at Southampton University, in England, announced to an astonished world that they had performed nuclear fusion in apparatus built on a laboratory bench. For a few weeks people dreamed of limitless clean power. But other researchers failed to replicate their results and it ...

    OAK RIDGE - Rusi Taleyarkhan is 49 years old, suddenly famous and emotionally spent."It's been a pressure-cooker for the past one year," said the senior scientist at Oak Ridge National Laboratory who has attracted worldwide attention this week regarding his research on "bubble fusion."In January 2001, after four years of study and experimentation, Taleyarkhan started seeing "interesting results" in his research with sono-luminescence - a phenomenon in which sound waves produce bubbles that collapse explosively and release energy in the form of light flashes. The feedback gave him confidence that the tabletop experiment might achieve nuclear fusion - the fusing ...

    WASHINGTON: An Indian-American scientist with the IIT imprimatur has, along with several American colleagues, caused a stir in the world scientific community by claiming to have achieved nuclear fusion in a small table top experiment.If it is proved right and authenticated by peers, such a fusion – the same principle that fuels the sun – could be the source of cheap, clean and limitless energy, and could change the world. Scientists have worked for decades in this direction and the possibility that a team might have cracked the problem is considered so remote that the announcement, to be reported in ...

    Gravity's quantum leaps detected &nbsp; 19:00&nbsp;16&nbsp;January&nbsp;02 Hazel Muir &nbsp; Gravity's subtle influence in the quantum world has been directly observed for the first time. On tiny scales, nature makes particles behave according to curiously rigid rules. For instance, negatively charged electrons trapped around a positive nucleus under the pull of the electromagnetic force cannot have any energy they want -they have to fall into a set of distinct energy levels. In the same way, the pull of gravity should make particles fall into discrete energy levels. But because gravity is extremely weak on small scales, the effect has been ...

    Once upon a time -- a bit more than 100 years ago -- many scientists believed that seemingly empty space wasn't empty at all, but was filled with a substance called luminous ether. This mysterious stuff, never seen in any laboratory on Earth, was thought to explain how gravity from one celestial body could affect another. By the end of the 19th century, though, luminous ether had gone the way of countless other scientific misconceptions. Today, another mysterious substance beguiles astronomers, and this one isn't going away. In fact, it's been at the forefront of cosmological theories for decades. It's ...
