Quasar light variability linked to black hole mass
Quasars are some of the most luminous and distant objects in the universe - and appear to have something in common with ordinary light bulbs. view more (2007-01-09)
Are we trading energy conservation for toxic air emissions?
A team of Yale scientists has found that certain countries and some U.S. states stand to benefit from the use of compact fluorescent lighting more than others in the fight against global warming. Some places may even produce more mercury emissions by switching from incandescent light bulbs to compact fluorescent lighting. view more (2008-10-01)
Cheap and efficient white light LEDs new design described in AIP's Journal of Applied Physics
Roughly 20 percent of the electricity consumed worldwide is used to light homes, businesses, and other private and public spaces. Though this consumption represents a large drain on resources, it also presents a tremendous opportunity for savings. view more (2009-04-08)
The Green (and blue, red, and white) lights of the future
A revolution in energy-efficient, environmentally-sound, and powerfully-flexible lighting is coming to businesses and homes, according to a paper in latest special energy issue of Optics Express, the Optical Society's (OSA) open-access journal. view more (2008-12-17)
Researchers lay out vision for lighting 'revolution'
A "revolution" in the way we illuminate our world is imminent, according to a paper published this week by two professors at Rensselaer Polytechnic Institute. view more (2008-12-19)
New materials for high efficiency organic solid state lighting
A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting devices which can be far more efficient than... view more... (2006-03-30)
Freeing light shines promise on energy-efficient lighting
The latest bright idea in energy-efficient lighting for homes and offices uses big science in nano-small packages to dim the future Edison's light bulb. view more (2008-07-16)
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)
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)
New coating is virtual black hole for reflections
Researchers have created an anti-reflective coating that allows light to travel through it, but lets almost none bounce off its surface. At least 10 times more effective than the coating on sunglasses or computer monitors, the material, which is made of silica nanorods, may be used to channel light into solar cells or allow more photons to surge... view more...

Sustainably grown garlic
Consumer interest in new and diverse types of garlic is on the rise. Fueled by factors including the growth of the "local foods" movement, interest in world cuisines, and widespread reports touting its numerous health benefits, demand for high-quality, locally grown garlic is increasing throughout the U.S. view more (2009-11-04)
Electronic displays that fit on clothing could power revolution in lighting
A thin film of plastic which conducts electricity and produces solar power could be the basis for a revolution in the way we light our homes and design clothes. view more (2007-04-19)
UCLA physicists create world's smallest incandescent lamp
In an effort to explore the boundary between thermodynamics and quantum mechanics - two fundamental yet seemingly incompatible theories of physics - a team from the UCLA Department of Physics and Astronomy has created the world's smallest incandescent lamp. view more (2009-05-07)
Optical wireless and broadband over power lines: High speed, secure Wi-Fi alternative
Penn State engineers have shown that a white-LED system for lighting and high data-rate indoor wireless communications, coupled with broadband over either medium- or low-voltage power line grids (BPL), can offer transmission capacities that exceed DSL or cable and are more secure than RF. view more (2006-01-12)
Carbon-based quantum dots could mean 'greener' safer technology in medicine and biology
Chemists at Clemson University say they have developed a new type of quantum dot that is the first to be made from carbon. view more (2006-05-24)
Mystery Of Sterility Of The Garlic Plant Solved By Hebrw University Researchers
Restoration of fertility to the now-sterile garlic plant has been accomplished by Israeli researchers, thus opening the way to wide-ranging scientific research that could lead to improved yields and quality. view more (2004-09-02)
Ambient light influences the evolution of colour signals
In light-contrasted ecosystems, ambient light and background colours influence the evolution of animal coloration. Because maximal conspicuousness is achieved for signals which are rich in the colours of ambient light but poorly reflected by background, different signals will be cryptic or conspicuous at different heights in tropical rainforest.... view more...

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)
High efficiency flat light source invented
Scientists studying organic light-emitting devices (OLEDs) have made a critical leap from single-color displays to a highly efficient and long-lived natural light source. view more (2006-04-13)
Cash Boost For UK High-tech Businesses With Bright Ideas
Improved mobile phone screens and new super-concrete are amongst the research projects sharing £5.4million, the largest DTI payout in recent years to EUREKA projects. 36 UK companies involved in 17 research projects are to benefit from funding through their involvement in EUREKA, the Europe-wide, government-funded initiative, Science... view more...
