From zero to a billion electron volts in 3.3 centimeters EurekAlert! BERKELEY, CA -- In a precedent-shattering demonstration of the potential of laser-wakefield acceleration, scientists at the Department of Energy's Lawrence Berkeley National Laboratory, working with colleagues at the University of Oxford, have accelerated electron beams to energies exceeding a billion electron volts (1 GeV) in a distance of just 3.3 centimeters. CITE Calibration Lab meet ISO 17025:2000 standard Sun Star THE Center for Industrial Technology and Enterprise (CITE) Electrical Standards and Testing Laboratory or CITE Calibration Laboratory has been validated to conform to the requirements of the Philippine National Standard/International Standard Organization/International Electrotechnical Committee (PNS ISO/IEC) 17025:2000.

The researchers report their results in the Japan launches Sun 'microscope' Central Chronicle Japan, Sept 24: Scientists have high hopes for Japan's Solar-B mission which has been launched from the Uchinoura spaceport. The spacecraft will investigate the colossal explosions in the Sun's atmosphere known as solar flares. NASA Cassini Significant Events for 09/14/06 - 09/20/06 SpaceRef The most recent spacecraft telemetry was acquired Wednesday, September 20, from the Goldstone tracking stations. The Cassini spacecraft is in an excellent state of health and is operating normally.

Walker remembers the day her memories vanished. Eyes on the future Lawrence Journal-World I look up, squinting across the room. “Katy, what did he get?” That’s right: My daughter and I are watching ABC-TV’s “Dancing with the Stars.” And as I work on my laptop, I overhear the announcer say Emmitt Smith, the legendary NFL running back, had just performed a “quick step” routine. Emmitt Smith, dancing? I’ve got to see this. New Device Tests Uncertainty Principle With New Precision Science Daily Keith Schwab, Cornell associate professor of physics, has created a device that approaches the quantum mechanical limit with the greatest precision ever relative to its size. And surprisingly, it also has shown how researchers can lower the temperature of an object -- just by watching it. Hard-wiring The Fruit Fly's Visual System Science Daily It is generally thought that the part of the brain in vertebrates that uses nerve cells to represent the outside world cannot only be genetically programmed but also requires activity by neurons or nerve cells in the brain. However, a study in fruit flies shows that this neuronal activity is not required for the formation of such visual maps.
