'Tornadoes' are transferred from light to sodium atoms
For the first time, tornado-like rotational motions have been transferred from light to atoms in a controlled way at the National Institute of Standards and Technology (NIST). view more (2006-11-10)
Lasers Generate Underwater Sound
Scientists at the Naval Research Laboratory are developing a new technology for use in underwater acoustics. The new technology uses flashes of laser light to remotely create underwater sound. view more (2009-09-08)
Physicist makes new high-res panorama of Milky Way
Cobbling together 3000 individual photographs, a physicist has made a new high-resolution panoramic image of the full night sky, with the Milky Way galaxy as its centerpiece. view more (2009-10-29)
Luminescence shines new light on proteins
A chance discovery by a team of scientists using optical probes means that changes in cells in the human body could now be seen in a completely different light. view more (2008-11-12)
Measuring the smallest particles
When someone says: "Everything flows - nothing stays the same", he seldomly refers to toothpaste, ointment or paint. However, manufacturers are immensely interested in the way in which such products "flow" in daily use. For example, wall paint should be thin in consistency, easy to work with and still adhere to walls after application. The amount... view more... (2001-06-25)
Polarizing filter allows astronomers to see disks surrounding black holes
For the first time, a team of international researchers has found a way to view the accretion disks surrounding black holes and verify that their true electromagnetic spectra match what astronomers have long predicted they would be. view more (2008-07-24)
Perfect image without metamaterials ... and a reprieve for silicon chips
Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image - images with perfect resolution that can stem from light being moved in odd directions to create, among other tricks of the light, the illusion of invisibility. view more (2009-09-29)
Important role of groundwater springs in shaping Mars
Data and images from Mars Express suggest that several Light Toned Deposits, some of the least understood features on Mars, were formed when large amounts of groundwater burst on to the surface. view more (2008-12-12)
Flat-pack loudspeakers
IMAGINE the din. Every cardboard-packed item in a supermarket could soon be blaring out reduced-price messages or playing advertising jingles. It`s just one of the uses being touted for a build-it-yourself, flat-pack loudspeaker developed by British company NXT. The Cambridge-based firm`s... view more... (2002-02-13)
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)
Light-protection for food packaging
Oxygen and light can alter the taste of foodstuffs. Manufacturers of packaging materials therefore try to protect contents from their influence. The latest approach is to use natural dyes in transparent plastic wrappers that selectively filter light. view more (2002-02-01)
New lens device will shrink huge light waves to pinpoints
Manipulating light waves, or electromagnetic radiation, has led to many technologies, from cameras to lasers to medical imaging machines that can see inside the human body. view more (2007-07-13)
Sticky surfaces turn slippery with the flip of a molecular light switch
Changing a surface from sticky to slippery could now be as easy as flipping a molecular light switch. view more (2006-06-20)
The science of hammering
When it comes to something as simple as hammering a nail, some people are naturals and get the job done after a few clean, sharp strokes of the hammer, whereas for the rest of us a similar challenge is likely to end up with the nail bent in the middle, a sore thumb and a wounded pride. view more (2009-06-29)
Rice researchers gain new insight into nanoscale optics
New research from Rice University has demonstrated an important analogy between electronics and optics that will enable light waves to be coupled efficiently to nanoscale structures and devices. view more (2005-09-15)
Polarized light guides cholera-carrying midges that contaminate water supplies
Cholera is a major killer and since the first pandemic in the early 19th century it has claimed millions of lives. According to Amit Lerner from The Hebrew University of Jerusalem, Israel, the lethal infection is harboured by an equally infamous insect: chironomids (midges). view more (2008-10-31)
Physicists meet to discuss $170 million neutrinos project
Physicists from all over the world will meet this week at the University of Sussex to discuss the latest developments in a $170 million project called MINOS. view more (2002-09-09)
TU Delft demonstrates for the first time how light squeezes through small holes
How does light pass through a tiny hole" For the first time, Dr Aurele Adam and Prof. Paul Planken of Delft University of Technology, in conjunction with two South Korean and one German research groups, have succeeded in mapping this process properly. view more (2008-05-09)
How white is a paper?
Whiter paper and better color reproduction are examples of important competitive advantages on an international market. view more (2009-10-23)
High-tech textiles pave the way for glowing garments
Researchers at The University of Manchester have developed high-tech battery-powered textile yarns that can be used to make clothing glow in the dark. view more (2007-10-29)
