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)

Internal Clock, External Light Regulate Plant Growth
Most plants and animals show changes in activity over a 24-hour cycle. Now, for the first time, researchers have shown how a plant combines signals from its internal clock with those from the environment to show a daily rhythm of growth.   view more (2007-07-10)

Light-activated compound silences nerves, may one day help epileptics
Brain activity has been compared to a light bulb turning on in the head. Scientists at Washington University School of Medicine in St. Louis have reversed this notion, creating a drug that stops brain activity when a light shines on it.   view more (2007-03-07)

Hard shell, glowing core
Tiny semiconductor crystals can be prompted to give off light - brighter than conventional dyes and in wavelength ranges that these only produce under certain conditions. Israeli chemist Uri Banin and his coworker Yun-Wie Cao demonstrated this with several core/shell nanocrystals made of the... view more (1999-12-09)

Laser experiments reveal strange properties of superfluids
Princeton University electrical engineers are using lasers to shed light on the behavior of superfluids - strange, frictionless liquids that are difficult to create and study.   view more (2006-12-26)

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)

New Research could benefit drivers who are sensitive to night-time glare conditions
A new technique to measure the effect of bright light on the human eye could result in safer and more user-friendly lighting conditions. The technique, which records the electrical activity of a major muscle surrounding the eye, opens the way to measuring the discomfort of the eye in conditions of... view more (2001-09-26)

New study: Why solar cells lose potency
Commercial products such as laptop computer monitors and solar-powered calculators are constructed from a light-sensitive material with a peculiar problem: When exposed to intense light, it forms defects, reducing the efficiency of the solar cells by 10 to 15 percent.   view more (2005-06-20)

Structuring polymers by laser
Microstructured polymer components are often used to direct light in optical devices. As an alternative to mechanical processes, laser light can also be used to produce the microscopic relief structures, and even to remove them without contact. With a flash of blue-green light, the show begins.... view more (2004-05-14)

U of MN study finds health education helps African American light smokers kick the habit
The first clinical trial to focus on light smokers shows that African Americans are motivated to quit more by completing health education than by using nicotine gum.   view more (2006-05-31)

Viagra®, unlikely tool for vision research, slows the visual response to flickering light
Therapeutic doses of Viagra¬Æ have been shown to influence the rate at which visual signals are integrated by the brain, affecting the way quick, repeated events, such as flickering light, are perceived.   view more (2006-01-24)

Experimental atomic clock uses ytterbium 'pancakes'
Scientists at the National Institute of Standards and Technology (NIST) working with Russian colleagues have significantly improved the design of optical atomic clocks that hold thousands of atoms in a lattice made of intersecting laser beams.   view more (2006-03-07)

Revamped experiment could detect elusive particle, physicists say
An experiment called "shining light through walls" would seem hard to improve upon. But University of Florida physicists have proposed a way to do just that, a step they say considerably improves the chance of detecting one of the universe's most elusive particles, a candidate for the... view more (2007-04-26)

RC-LEDs - Super-fast light sources suitable for data transfer
Resonance-cavity light-emitting diodes (RC-LEDs) are a new type of light source which produces very intense light from quantum wells located in a microcavity. As light sources, RC-LEDs are classified as something between laser diodes and conventional light-emitting diodes (LEDs). The advantages of... view more (2000-02-25)

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)

Laser analyses fuel flame
In a project from the Technology Foundation STW, researcher Roger Evertsen has introduced a new method for measuring the composition of fuel flames. The technique makes use of laser light and is not only quick but also extremely sensitive.   view more (2002-11-15)

Light therapy could be a new approach to treating patients with pancreatic cancer
Pancreatic cancer is notoriously difficult to treat, largely because of the location of the pancreas close to major arteries and vital organs, and the effects of a poorly functioning pancreas on the rest of the body. It is one of the top 10 leading causes of death from cancer worldwide, and in the... view more (2002-03-11)

European light research opens door for optical storage and computing
The goal of replacing electronics with optics for processing data in computers is coming closer through cutting edge European research into the mysterious properties of "fast and slow" light.   view more (2008-04-25)

Tiny holes offer surprising insights
Researchers from Berlin and Seoul store light in plasmonic crystals   view more (2005-03-04)

Diode laser could be vital for safeguarding aircraft
Terrorists can strike anywhere, at any time, and aircraft, both military and civilian, are targets for heat-seeking missiles, one of many tactics in use by groups hostile to the United States.   view more (2006-09-01)

Pyramids give batteries a longer life
A way of increasing battery life in devices such as laptop computers, personal TVs and camcorders is reported today in the Institute of Physics Journal, Journal of Micromechanics and Microengineering. Researchers at the University of Michigan and the National Taiwan University, have developed a... view more (2000-06-22)

Transparent sinter alumina
The efficiency of halogen lamps could be increased by using pure sinter alumina instead of quartz glass. But the presently available types of this ceramic material diffuse the light. New and transparent ceramics for parts in almost any shape are highly pressure-resistant. Halogen plasma lamps emit... view more (2002-03-05)

Laser Therapy Offers Alternative to Surgery for Liver Tumours
Research News in the British Journal of Surgery 11 September 2003: Laser light can be delivered in a controlled and predictable manner to destroy tumours. By inserting fibre optic cables through needles, doctors can direct the powerful laser light onto liver tumours - killing the cells and thus... view more (2003-09-11)

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)

New infrared tool measures silicon wafer thickness
In the last few years, semiconductor circuit features have shrunk to sub-100 nanometer (nm) dimensions, while the size of the thin silicon wafers that these circuits are constructed on has grown from 200 millimeters (mm) to 300 mm (about 12 inches). The payoff is a higher yield of finished devices... view more (2005-07-15)
