The search for new applications for laser light beams
Light can blind or distort colours, or confuse one with chiaroscuros. But it can have greater usefulness if its properties, characteristics, how it is created, etcetera are better understood. view more (2006-05-30)
New magnets with 99% air content
Researchers from the Physics Department at the Universitat Autònoma de Barcelona (UAB), the Institut de Cie'nca de Materials de Barcelona (ICMAB-CSIC), and the Universidad de Zaragoza have created a new ultra-light transparent magnetic material. Thanks to its properties, the new material could have interesting technological applications,... view more... (2003-11-25)
Children with autism show slower pupil responses, MU study finds
Autism affects 1 in 150 children today, making it more common than childhood cancer, juvenile diabetes and pediatric AIDS combined. view more (2009-11-11)
Calm before the spawn: Climate change and coral spawning
What's the point of setting up marine reserves to protect coral reefs from pollution, ship groundings and overfishing if climate change could cause far more damage? A study published this week in London in Proceedings of the Royal Society B provides the answer. view more (2009-11-04)
Engineering the road to safer streetlighting
An innovative engineering project could lead to fewer night-time accidents on badly lit roads. It is developing a revolutionary way of assessing whether roads are equipped with appropriate levels of streetlighting. The new assessment system is quicker, cheaper and more comprehensive than methods previously used. It can also help local... view more... (2002-12-09)
Microbes use sunscreens too
Microbes can withstand extreme levels of atmospheric ultraviolet light (UV) by producing their own sunscreens. Unlike humans, some bugs may even be able to survive without any help from the ozone layer scientists heard today (Thursday 19 September) at the Society for General Microbiology autumn meeting at Loughborough University. "A group of... view more... (2002-08-28)
Scientists discover 'light echoes' of ancient supernovae
Astronomers have found "light echoes" from three ancient supernovae by detecting their faint, centuries-old light reflected in the clouds of interstellar dust. view more (2005-12-23)
'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)
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)
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)
Varnish measures pressure and vibrations
Despite the use of computer simulation, wind tunnel testing is still required to measure pressure changes and airflow speeds on the surfaces of new aircraft and automobile prototypes. Such testing is now done less with smoke visualization and threads but more frequently with high-tech sensors which have the least influence on air flows. Film... view more... (2003-02-20)
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)
