New Technology To Help Early Skin Cancer Diagnosis
Computer scientists in the UK have invented a new technology to help doctors diagnose skin cancer while it is still in its early stages, greatly improving the chances of successful treatment. The work has been carried out by a team led by Dr Ela Claridge in the University of Birmingham's School of... view more (2000-04-11)

Researchers generate high-speed pulses of laser light on silicon, speeding data transmission
In the Sept. 3 issue of Optical Society of America's Optics Express, published online today, researchers announce that they have built the world's first "mode-locked silicon evanescent laser."   view more (2007-08-22)

Common algae helps illustrate mammalian brain electrical circuitry
Mice whose brain cells respond to a flash of light are providing insight into the complexities of the sense of smell and may ultimately yield a better understanding of how the human brain works.   view more (2007-04-19)

Action Replay of Powerful Stellar Explosion
Astronomers have made the best ever determination of the power of a supernova explosion that was visible from Earth long ago. By observing the remnant of a supernova and a light echo from the initial outburst, they have established the validity of a powerful new method for studying supernovas.   view more (2008-03-24)

Lighter gas reduces damage to optics in extreme ultraviolet lithography
Researchers at the University of Illinois have discovered a way to generate light and reduce damage in a leading candidate for next-generation microelectronics lithography. The technique could help pack more power into smaller computer chips.   view more (2007-09-13)

Nanoparticle technique could lead to improved semiconductors
Devices made from plastic semiconductors, like solar cells and light-emitting diodes (LEDs), could be improved based on information gained using a new nanoparticle technique developed at The University of Texas at Austin.   view more (2007-08-07)

Laser Goes Tubing for Faster Body-Fluid Tests
University of Rochester researchers announce in the current issue of Applied Optics a technique that in 60 seconds or less measures multiple chemicals in body fluids, using a laser, white light, and a reflective tube.   view more (2007-04-03)

Nasty bacteria need sunlight to do their worst
Certain types of bacteria have sunlight-sensing molecules similar to those found in plants, according to a new study. Surprisingly, at least one species-responsible for causing the flu-like disorder Brucellosis-needs light to maximize its virulence. The work suggests an entirely new model for... view more (2007-08-24)

Tethered Molecules Act as Light-Driven Reversible Nanoswitches
The ability to see is based on molecules in the eye that flip from one conformation to another when exposed to visible light.   view more (2008-06-24)

Different Processes Govern Sight, Light Detection
A Johns Hopkins University biologist, in research with implications for people suffering from seasonal affective disorder and insomnia, has determined that the eye uses light to reset the biological clock through a mechanism separate from the ability to see.   view more (2008-04-28)

Photonic Crystals in 3-D - The Physics Congress 2003
Telecoms systems contain an awkward mixture of optics and electronics. A purely optical system would permit the very high data rates needed by the Internet, but at the moment the switching and routing, as well as the "last mile" to the customer, still depend on slower electronic... view more (2003-03-17)

heic0812: The Antennae Galaxies move closer
New research on the Antennae Galaxies using the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope shows that this benchmark pair of interacting galaxies is in fact much closer than previously thought - 45 million light-years instead of 65 million light-years   view more (2008-05-12)

Orphan stars found in long galaxy tail
Astronomers have found evidence that stars have been forming in a long tail of gas that extends well outside its parent galaxy. This discovery suggests that such "orphan" stars may be much more prevalent than previously thought.   view more (2007-09-21)

UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the... view more (2007-06-01)

Starburst Galaxy Showers The Universe
When a galaxy known as M82 had a near-miss with its neighbour, it set off an explosive burst of star formation that sent plumes of hot gas tens of thousands of light years into space. Now a team of UK and American astronomers has discovered that these gas clouds are like the jets from a high... view more (2004-05-21)

It`s wet out there
TANTALISING signs of water have been found in the atmospheres of planets orbiting distant stars. If the discovery is confirmed, it will fuel speculation that the Galaxy is teeming with life. "This would be a historic discovery- the first detection of a prebiotic molecule in an extrasolar planet,"... view more (2002-09-20)

Nano-sized Electronic Circuit Promises Bright View of Early Universe
A newly developed nano-sized electronic device is an important step toward helping astronomers see invisible light dating from the creation of the universe. This invisible light makes up 98% of the light emitted since the "big bang," and may provide insights into the earliest stages of... view more (2008-07-11)

Researchers create a broadband light amplifier on a chip
Cornell researchers have created a broadband light amplifier on a silicon chip, a major breakthrough in the quest to create photonic microchips. In such microchips, beams of light traveling through microscopic waveguides will replace electric currents traveling through microscopic wires.   view more (2006-07-07)

Despite darkness, nocturnal bees learn visual landmarks while foraging at night
Day-active bees, such as the honeybee, are well known for using visual landmarks to locate a favoured patch of flowers, and to find their way home again to their hive. Researchers have now found that nocturnal bees can do the same thing, despite experiencing light intensities that are more than 100... view more (2004-08-10)

Ready to go: mobile terahertz devices
Terahertz waves, which until now have barely found their way out of the laboratory, could soon be in use as a versatile tool. Researchers have mobilized the transmitting and receiving devices so that they can be used anywhere with ease.   view more (2008-04-09)

NYU scientists set stage for understanding how color vision is processed
New York University biologists have mapped the medulla circuitry in fruit flies, setting the stage for subsequent research on how color vision is processed.   view more (2008-03-26)

UK researchers aim to create black holes in the lab
Physicists in the UK are planning pioneering experiments to create tiny, artificial black holes in the laboratory which will be able to suck in light or sound waves. The researchers hope that the desk-top black holes will provide important information about the fundamental behaviour of matter and... view more (2001-01-19)
