A sub-femtosecond stop watch for 'photon finish' races
Using a system that can compare the travel times of two photons with sub-femtosecond precision, scientists at the Joint Quantum Institute (a partnership of the National Institute of Standards and Technology (NIST) and the University of Maryland) and Georgetown University have found a remarkably... view more (2008-03-14)

Astronomers find grains of sand around distant stars
In a find that sheds light on how Earth-like planets may form, astronomers this week reported finding the first evidence of small, sandy particles orbiting a newborn solar system at about the same distance as the Earth orbits the sun. The report will be published online this week by the journal... view more (2008-03-13)

New NIST detector can 'see' single neutrons over broad range
Researchers at the National Institute of Standards and Technology (NIST) and the University of Maryland have developed a new optical method that can detect individual neutrons and record them over a range of intensities at least a hundred times greater than existing detectors.   view more (2008-03-11)

Physics breakthrough much ado about 'nothing'
How do scientists store nothing? It may sound like the beginning of a bad joke, but the answer is causing a stir in the realm of quantum physics after two research teams, including one from the University of Calgary, have independently proven it's possible to store a special kind of vacuum in a... view more (2008-03-06)

Large binocular telescope achieves first binocular light
The Large Binocular Telescope on Mount Graham, Ariz., has taken celestial images using its twin side-by-side, 8.4-meter (27.6 foot) primary mirrors together, achieving first "binocular" light.   view more (2008-03-06)

Bright lights: Mystery of glowing antibody solved by Scripps research scientists
Now, a group of Scripps Research scientists have shown that EP2-19G2, one of a panel of fluorescent monoclonal antibodies that were first reported in 2000, produces its distinctive bright blue glow through a rare and highly complex recombination of electrical charge.   view more (2008-02-29)

NASA's Swift satellite images a galaxy ablaze with starbirth
Combining 39 individual frames taken over 11 hours of exposure time, NASA astronomers have created this ultraviolet mosaic of the nearby "Triangulum Galaxy."   view more (2008-02-26)

Electron filmed for first time ever
Now it is possible to see a movie of an electron. The movie shows how an electron rides on a light wave after just having been pulled away from an atom.   view more (2008-02-25)

Astronomers discover largest-ever dark matter structures spanning 270M light-years
A University of British Columbia astronomer with an international team has discovered the largest structures of dark matter ever seen. Measuring 270 million light-years across, these dark matter structures criss-cross the night sky, each spanning an area that is eight times larger than the full... view more (2008-02-22)

Researcher investigates new developments in laser and sensor technology
Scientists hope that research being conducted in Binghamton University's Department of Physics, Applied Physics and Astronomy will create lasers that work at wavelengths currently inaccessible.   view more (2008-02-22)

Optical 'frequency comb' can detect the breath of disease
Exhale on a cold winter day and you will see the water vapor coming out of your mouth. Light up your breath with a Nobel-Prize-related tool, and you could potentially detect trace amounts of over 1,000 compounds, some of which provide early warning signs of disease.   view more (2008-02-20)

Chemists measure copper levels in zinc oxide nanowires
Chemists at the National Institute of Standards and Technology (NIST) have been the first to measure significant amounts of copper incorporated into zinc oxide (ZnO) nanowires during fabrication.   view more (2008-02-20)

Laser light may be able to detect diseases on the breath
A team of scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) at Boulder, has shown that by sampling a person's breath with laser light they can detect molecules in the breath that may be markers for diseases like... view more (2008-02-19)

Scientists using laser light to detect potential diseases via breath samples, says new study
By blasting a person's breath with laser light, scientists from the National Institute of Standards and Technology and the University of Colorado at Boulder have shown that they can detect molecules that may be markers for diseases like asthma or cancer.   view more (2008-02-19)

Researchers decode genetics of rare photosynthetic bacterium
A bacterium that harvests far-red light by making a rare form of chlorophyll (chlorophyll d) has revealed its genetic secrets, according to a team of researchers who recently sequenced the bacteria's genome.   view more (2008-02-11)

Light echoes whisper the distance to a star
Taking advantage of the presence of light echoes, a team of astronomers have used an ESO telescope to measure, at the 1% precision level, the distance of a Cepheid - a class of variable stars that constitutes one of the first steps in the cosmic distance ladder.   view more (2008-02-11)

Optical Atomic Clock: A long look at the captured atoms
Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light.   view more (2008-02-06)

Bacterium sequenced makes rare form of chlorophyll
Researchers at Washington University in St. Louis and Arizona State University have sequenced the genome of a rare bacterium that harvests light energy by making an even rarer form of chlorophyll, chlorophyll d. Chlorophyll d absorbs "red edge," near infrared, long wave length light,... view more (2008-02-05)

'Smart' holograms help patients help themselves
Patients with diabetes, cardiac problems, kidney disorders or high blood pressure could benefit from the development of new hologram technology.   view more (2008-02-04)

Separate signals through optical fibres for ultrafast home network
Dutch-sponsored researcher Christos Tsekrekos has investigated how a small network for at home or in a company can function optimally. His research analyses the MGDM technique (Mode Group Diversity Multiplexing) of the Eindhoven University of Technology.   view more (2008-01-25)

JILA solves problem of quantum dot 'blinking'
Quantum dots-tiny, intense, tunable sources of colorful light-are illuminating new opportunities in biomedical research, cryptography and other fields. But these semiconductor nanocrystals also have a secret problem, a kind of nervous tic. They mysteriously tend to "blink" on and off like... view more (2008-01-24)
