Researchers create a broadband light amplifier on a chip
Cornell researchers have created a broadband light amplifier on a silicon chip, a major breakthrough in the quest to create photonic microchips. In such microchips, beams of light traveling through microscopic waveguides will replace electric currents traveling through microscopic wires.   view more (2006-07-07)

Gold nanostars outshine the competition
Novel nanoparticles being tested at the National Institute of Standards and Technology (NIST) have researchers seeing stars. In a recent paper, NIST scientists used surface-enhanced Raman spectroscopy (SERS) to demonstrate that gold nanostars exhibit optical qualities that make them superior for... view more (2008-10-16)

Magnet Lab researchers make observing cell functions easier
Now that the genome (DNA) of humans and many other organisms have been sequenced, biologists are turning their attention to discovering how the many thousands of structural and control genes -- the "worker bees" of living cells that can turn genes on and off -- function.   view more (2008-05-09)

Hydrogen tank lighter than battery
Dutch-sponsored researcher Robin Gremaud has shown that an alloy of the metals magnesium, titanium and nickel is excellent at absorbing hydrogen.   view more (2008-11-05)

Bringing astronomy into sharper focus
Scientists from the University of Cambridge's Astrophysics Group have today (21 June 2002) announced a collaboration with teams based in New Mexico, Puerto Rico and at the Naval Research Laboratory in Washington DC to design, install and operate a novel type of astronomical telescope for ultra-high... view more (2002-06-21)

Cancer diagnosis - the Star Trek way
A small portable optical tool that can simply be pointed at the body to detect cancerous cells or reveal how body tissue is being affected by laser or cryogenic therapy could one day be the result of research being carried out by laser physicists at Imperial College.   view more (2000-03-21)

Metal-organic frameworks feel the pressure of Argonne scientists
Scientists at U.S. Department of Energy's Argonne National laboratory are putting the pressure on metal-organic frameworks (MOF).   view more (2008-09-26)

Scientists demonstrate high-performing room-temperature nanolaser
Scientists at Yokohama National University in Japan have built a highly efficient room-temperature nanometer-scale laser that produces stable, continuous streams of near-infrared laser light.   view more (2007-06-21)

MIT develops 'tractor beam' for cells, more
In a feat that seems like something out of a microscopic version of Star Trek, MIT researchers have found a way to use a "tractor beam" of light to pick up, hold, and move around individual cells and other objects on the surface of a microchip.   view more (2007-10-31)

Pioneering research could make UK a world leader
Speculative research being pioneered at Northumbria University could make major medical advances in screening patients in the future. Dr David Smith from the School of Engineering and Technology is developing a microwave imaging system which would replace X-rays. The work, currently under patent,... view more (2003-11-13)

Cooling with tiny crystals
Refrigeration equipment prevents sweaty brows in the summer and also keeps our food fresh for longer periods. With CryoSol®, a new and easily pumpable liquid ice suspension, space requirements for cold storage are much lower than with conventional coolants.   view more (2004-08-27)

Metabolic syndrome -- don't blame the belly fat
Abdominal fat, the spare tire that many of us carry, has long been implicated as a primary suspect in causing the metabolic syndrome, a cluster of conditions that includes the most dangerous heart attack risk factors: prediabetes, diabetes, high blood pressure, and changes in cholesterol.   view more (2007-07-17)

Tiny spectrometer offers precision laser calibration
A tiny device for calibrating or stabilizing precision lasers has been designed and demonstrated at the National Institute of Standards and Technology (NIST).   view more (2007-05-14)

Primitive Visitor From Space Arrives In UK
Scientists from the Natural History Museum (NHM) in London, working with colleagues from the Open University (OU) in Milton Keynes, have been examining an intriguing arrival from outer space. The Tagish Lake meteorite, which fell in the Yukon region of northern Canada on the morning of 18 January... view more (2001-03-31)

The accretion disks around super-massive black holes: do they really exist?
Active Galactic Nuclei (AGN) and quasars (QSO) are the most luminous objects in the sky. These are powered by accretion of interstellar gas onto a supermassive black hole (BH) of about 100 millions solar masses which stands at the center of galaxies. For Seyfert galaxies, a few tenths of solar... view more (2001-04-17)

Researchers use light to detect Alzheimer's
A team of researchers in Bedford, Mass. has developed a way of examining brain tissue with near-infrared light to detect signs of Alzheimer's disease.   view more (2008-03-17)

Bon MOT: Innovative atom trap catches highly magnetic atoms
A research team from the National Institute of Standards and Technology (NIST) and the University of Maryland has succeeded in cooling atoms of a rare-earth element, erbium, to within two millionths of a degree of absolute zero using a novel trapping and laser cooling technique.   view more (2008-04-03)

Tiny fuel cell might replace batteries in laptop computers, portable electronics
If you're frustrated by frequently losing battery power in your laptop computer, digital camera or portable music player, then take heart: A better source of "juice" is in the works.   view more (2006-09-13)

Resilient form of plant carbon gives new meaning to term 'older than dirt'
A particularly resilient type of carbon from the first plants to regrow after the last ice age - and that same type of carbon from all the plants since - appears to have been accumulating for 11,000 years in the forests of British Columbia, Canada.   view more (2006-11-27)

Beyond batteries: Storing power in a sheet of paper
Researchers at Rensselaer Polytechnic Institute have developed a new energy storage device that easily could be mistaken for a simple sheet of black paper.   view more (2007-08-14)
