Astronomers use laser to take clearest images of the center of the Milky Way
UCLA astronomers and colleagues have taken the first clear picture of the center of our Milky Way galaxy, including the area surrounding the supermassive black hole, using a new laser virtual star at the W.M. Keck observatory in Hawaii. view more (2005-12-21)
Holograms make for better vision tests
A new paper published in the July 1 issue of OSA's Optics Letters shows that researchers in Australia have created a new one-step test that uses holograms to diagnose the astigmatic error of the human eye, a key measurement in determining the appropriate prescriptions for eye glasses in patients. view more (2007-07-09)
Engineering algae to make fuel instead of sugar
In pursuing cleaner energy there is such a thing as being too green. Unicellular microalgae, for instance, can be considered too green. view more (2008-12-17)
World's fastest and most sensitive astronomical camera
The next generation of instruments for ground-based telescopes took a leap forward with the development of a new ultra-fast camera that can take 1500 finely exposed images per second even when observing extremely faint objects. view more (2009-06-19)
First Bose-Einstein condensation of strontium
In an international first, scientists from the Institute of Quantum Optics and Quantum Information (IQOQI) produced a Bose-Einstein condensate of the alkaline-earth element strontium, thus narrowly winning an international competition between many first-rate scientific groups view more (2009-11-10)
Two-drug treatment may block source of asthma and chronic bronchitis
Current treatments for asthma and chronic bronchitis aren't able to address the ultimate source of the problem-they can only alleviate symptoms. view more (2006-02-02)
An aerial for light
Austrian physicists report unusual light-metal interaction A team under Professor Franz Aussenegg at the University of Graz in Austria is looking into unusual interactions between light and submicroscopic metal particles. The physicists' findings represent a major advance towards the development of improved data storage media and optical sensors.... view more... (2003-02-17)
Titanic Weather Forecasting: New Detailed VLT Images of the Largest Moon in the Solar System
Optimizing space missions Titan, the largest moon of Saturn was discovered by Dutch astronomer Christian Huygens in 1655 and certainly deserves its name. With a diameter of no less than 5,150 km, it is larger than Mercury and twice as large as Pluto. It is unique in having a hazy atmosphere of nitrogen, methane and oily hydrocarbons. Although it... view more... (2004-04-01)
Precision optics hot off the press
Optical lenses have already become a mass product. They focus the bar code laser at the supermarket checkout, record pictures in cameras and mobile phones and control the transmission of data along fiber optic telecommunications cables. Automated production processes help to meet this ever-increasing demand for lenses. While simple plastic lenses... view more... (2003-04-24)
Experts from University of Leicester in Beagle 2 project
The University of Leicester Department of Physics and Astronomy has one of the largest space research centres of its kind in Europe. The University was co-founder of the £52million National Space Centre and is one of the principal partners in the Beagle 2 Project. For background information related to the Beagle 2 mission, the University is... view more... (2003-12-23)
Berkeley researchers create first hyperlens for sound waves
Ultrasound and underwater sonar devices could "see" a big improvement thanks to development of the world's first acoustic hyperlens. Created by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab), the acoustic hyperlens provides an eightfold boost in the magnification power of sound-based... view more...

A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. view more (2005-12-01)
Regular Light Bulbs Made Super-Efficient with Ultra-Fast Laser
An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. view more (2009-06-01)
University of Texas at Austin physicists slow and control supersonic helium beam
The speed of a beam of helium atoms can be controlled and slowed using an "atomic paddle" much as a tennis player uses a racquet to control tennis balls, physicists at The University of Texas at Austin have discovered. view more (2007-03-09)
Breath or Urine Analysis May Detect Cancer, Diabetes
A future sensor may take away a patient's breath while simultaneously determining whether the patient has breast cancer, lung cancer, diabetes or asthma. A University of Missouri researcher is developing a device that will analyze breath or urine samples for volatile markers inside the body that indicate disease. view more (2009-03-11)
