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)
Locusts' built-in 'surface analysis' ability directs them to fly overland
Swarms of millions of locusts have, since Biblical times and until our very own day, been considered a "plague" of major proportions, with the creatures destroying every growing thing in their path. view more (2005-08-12)
Advance by chemists may lead to better displays on laptop computers, cell phones
UCLA chemists working at the nanoscale have developed a new, inexpensive means of forcing luminescent polymers to give off polarized light and of confining that light to produce polymer-based lasers. view more (2007-09-18)
Squid Skin Reveals Hidden Messages
In the animal world, squid are masters of disguise. Pigmented skin cells enable them to camouflage themselves-almost instantaneously-from predators. view more (2006-09-22)
Mantis shrimps could show us the way to a better DVD
The remarkable eyes of a marine crustacean could inspire the next generation of DVD and CD players, according to a new study from the University of Bristol published today in Nature Photonics. view more (2009-10-26)
Polarized light pollution leads animals astray
Human-made light sources can alter natural light cycles, causing animals that rely on light cues to make mistakes when moving through their environment. view more (2009-01-07)
Northern lights glimmer with unexpected trait
An international team of scientists has detected that some of the glow of Earth's aurora is polarized, an unexpected state for such emissions. view more (2008-04-28)
Dictyostelium cells shown to lay 'breadcrumb trail' as first step in multicellular formation
When starved of their food source and then presented with a chemoattractant signal like cAMP, individual Dictyostelium cells acquire a polarized morphology and aggregate to form a migrating stream. view more (2008-12-01)
Light guides flight of migratory birds
Songbirds use multiple sources of directional cues to guide their seasonal migrations, including the Sun, star patterns, the earth's magnetic field, and sky polarized light patterns. view more (2006-08-11)
Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)
Scientists demonstrate laser with controlled polarization
Applied scientists at the Harvard School of Engineering and Applied Sciences (SEAS) in collaboration with researchers from Hamamatsu Photonics in Hamamatsu City, Japan, have demonstrated, for the first time, lasers in which the direction of oscillation of the emitted radiation, known as polarization, can be designed and controlled at will. view more (2009-04-13)
Polarizers may enhance remote chemical detection
Chemists can analyze the composition of a suspected bomb -- without actually touching and possibly detonating it -- using a technique called laser-induced breakdown spectroscopy, or LIBS. view more (2009-03-12)
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)
Meteorites delivered the 'seeds' of Earth's left-hand life
Flash back three or four billion years - Earth is a hot, dry and lifeless place. All is still. Without warning, a meteor slams into the desert plains at over ten thousand miles per hour. With it, this violent collision may have planted the chemical seeds of life on Earth. view more (2008-04-07)
MIT 'optics on a chip' may revolutionize telecom, computing
In work that could lead to completely new devices, systems and applications in computing and telecommunications, MIT researchers are bringing the long-sought goal of "optics on a chip" one step closer to market. view more (2007-02-06)
New aerosol observing technique turns gray skies to blue
Tiny, ubiquitous particles in the atmosphere may play a profound role in regulating global climate. But the scientists who study these particles -- called aerosols -- have long struggled to accurately measure their composition, size, and global distribution. view more (2009-03-13)
RIT scientist fine-tunes Hubble Space Telescope
A scientist at Rochester Institute of Technology has expanded the Hubble Space Telescope's capability without the need for new instruments or billions of dollars. view more (2009-03-26)
Physicists find way to control individual bits in quantum computers
Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised* a viable way to manipulate a single "bit" in a quantum processor without disturbing the information stored in its neighbors. view more (2009-07-08)
Loopy photons clarify 'spookiness' of quantum physics
Researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have developed a new method for creating pairs of entangled photons, particles of light whose properties are interlinked in a very unusual way dictated by the rules of quantum physics. view more (2008-03-19)
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)
