By TOM BEAL Energy expert Nate Lewis says nuclear fusion will solve our energy problems. Fusion occurring on our nearest star, 93 million miles away, produces enough energy in an hour to power our world for a year, says Lewis. We just need to find better ways to cheaply capture it and store it. Lewis is the George L. Argyros Professor of Chemistry at CalTech, the California Institute of Technology. He has studied energy worldwide and recently co-authored a study on Arizona's energy...

Scientists are currently seeking to develop new stronger steel in light of recent findings that show weakness in steel due to its magnetic properties. Dr Sergei Dudarev, principal scientist at the United Kingdom Atomic Energy Authority (UKAEA) told the British Association Science Festival that the Twin Towers in New York City fell because their steel backbones lost strength in the fires that resulted from the plane impacts. Their discovery marks the first time that experts have identified...

FOUR DOLLARS is more than just the current price for a gallon of gas. It's also the cost of getting Americans to pay attention to national energy policy. Unfortunately, $4 a gallon is still not enough to get politicians to shift beyond tired platitudes and political divisions. Perhaps after a few more months of paying history's highest prices for gas, heating oil and electricity, and with an election looming, voters will force Washington to do the right thing. In the meantime, U.S. Rep....

Using observations from NASA's Rossi X-ray Timing Explorer (RXTE), an international team of astronomers has discovered a timing mechanism that allows them to predict exactly when a superdense star will unleash incredibly powerful explosions. "We found a clock that ticks slower and slower, and when it slows down too much, boom! The bomb explodes," says lead author Diego Altamirano of the University of Amsterdam in the Netherlands. The bursts occur on a neutron star, which is the collapsed...

One of the great ongoing challenges of astrophysics, to find out how stars evolve and die, is to be tackled in an ambitious European research program. This will involve studying in the laboratory over 25 critical nuclear reactions using low-energy stable beams of ions, in order to understand stellar evolution. "This program will enhance the ongoing effort to understand the lifecycle of stars, together with the structure and processes of stellar evolution," said the workshop's convenor...

For about six months of the year, bursts of a hot, electrically charged gas, or plasma, swirl around a donut-shaped tube in a special MIT reactor, helping scientists learn more about a potential future energy source: nuclear fusion. During downtimes when the reactor is offline, as it is right now, engineers make upgrades that will help them achieve their goal of making fusion a viable energy source--a long-standing mission that will likely continue for decades. MIT's reactor, known as...

TEHRAN (Reuters) - Iran is pressing ahead with research tests on nuclear fusion, a type of atomic reaction which has yet to be developed for commercial power generation, a senior Iranian official said on Monday. Iran said in the 1990s it was working on nuclear fusion research but this is the first mention in years that the work is continuing and comes at a time of heightened tension over Iran's nuclear program. Iran has been hauled before the U.N. Security Council for failing to...

ALBUQUERQUE, N.M. -- A particle accelerator at Sandia National Laboratories has heated a swarm of charged particles to a record 2 billion degrees Kelvin, a temperature beyond that of a star's interior. Scientists working with Sandia's Z machine said the feat also revealed a new phenomenon that could eventually make future nuclear fusion power plants smaller and cheaper to operate than if the plants relied on previously known physics. "At first, we were disbelieving," said Chris Deeney, head...

INDIANAPOLIS -- Purdue University is investigating allegations that a scientist thwarted his colleagues' efforts to test his claims of producing nuclear fusion in tabletop experiments, even going so far as to remove high-tech equipment from a shared lab. Several Purdue researchers said Rusi Taleyarkhan, a Purdue professor of nuclear engineering, has stymied their attempts to verify - or refute - aspects of his controversial "bubble fusion" experiments since late 2003, when he joined Purdue's...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Purdue University is investigating complaints about a scientist who claimed to have achieved "cold fusion" using sound waves to make bubbles in a test tube, the university said on Wednesday. Nuclear engineer Rusi Taleyarkhan's work has been controversial since he published a study in 2002 claiming to have achieved the Holy Grail of energy production -- nuclear fusion at room temperature. Nuclear fusion is the...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
