Engineers ride 'rogue' laser waves to build better light sources
A freak wave at sea is a terrifying sight. Seven stories tall, wildly unpredictable, and incredibly destructive, such waves have been known to emerge from calm waters and swallow ships whole. view more (2009-03-06)
Discovery at UAB brings us nearer to making the dream of invisibility true
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light - very low frequency electromagnetic waves - by making the inside of the magnetic field zero but not altering the exterior field. view more (2009-07-08)
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 RC-LEDs compared with conventional LEDs include a... 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 UK kills around 6500 people every year. 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 film which increases the display brightness by 100... 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 a clearer and brighter light than conventional... 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 eliminating the need for major surgery. A review of... 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 from fewer wafers. view more (2005-07-15)
Darwin's greatest challenge tackled: the mystery of eye evolution
When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye evolved through spontaneous mutation and natural selection. Scientists at the European Molecular Biology Laboratory (EMBL) have now tackled Darwin's major challenge in an... view more... (2004-10-26)
Plants tell caterpillars when it's safe to forage
The world is filled with cues that could influence the daily feeding patterns of an organism. Many plants, for example, respond to foraging damage by releasing specialized chemical signals-volatile organic compounds that evaporate in the air-that attract the forager's natural enemies. view more (2006-05-16)
High in sodium: Highly charged tungsten ions may diagnose fusion energy reactors
Just as health-food manufacturers work on developing the best possible sodium substitutes for low-salt diets, physicists at the National Institute of Standards and Technology (NIST) have acquired new knowledge on a promising sodium alternative of their own. view more (2009-09-10)
NIST atom interferometry displays new quantum tricks
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a novel way of making atoms interfere with each other, recreating a famous experiment originally done with light while also making the atoms do things that light just won't do. view more (2007-05-29)
The crew will soon be able to watch you from the cockpit
AIRBUS, the European jet manufacturer, is planning to build concealed cameras into the light fittings above the seats in its aircraft. The idea is to let the crew monitor passengers and spot hijackers before they strike. The cameras also work in the dark. The move is part of an attempt to reassure... view more... (2002-05-08)
Lighting the Way: Measuring Surface Tension Just Got Easier
Inventors at Oxford University have developed a new method to indirectly measure the surface tension of liquid by tracking reflected light intensity to assess the surface configuration. The procedure is reliable, repeatable, quick to set-up and use, contact-less and non-destructive. Surface tension measurement is an important tool in the... view more... (2003-09-05)
