Light powered platinum more targeted & 80 times more powerful than similar cancer treatments
Researchers from the Universities of Warwick, Edinburgh, Dundee and the Czech Republic's Institute of Biophysics have discovered a new light-activated platinum-based compound that is up to 80 times more powerful than other platinum-based anti-cancer drugs and which can use "light activation" to kill cancer cells in much more targeted way... view more...

Guiding light - CMD19/CMMP with The Physics Congress 2002
A new type of optical material has been developed by physicists that could replace the electronics used to route the light signals through optical fibre telecommunications networks. It could even provide the basis for future `optical computers` working on light pulses instead of electric signals. At the Condensed Matter conference on Monday 8... view more... (2002-03-26)

Novel nano-etched cavity makes leds 7 times brighter
Researchers at the National Institute of Standards and Technology (NIST) have made semiconductor light-emitting diodes (LEDs) more than seven times brighter by etching nanoscale grooves in a surrounding cavity to guide scattered light in one direction.   view more (2006-07-24)

Scientists create world's most efficient light-bulb
Scientists have successfully produced the most efficient light bulb ever - but on the microscopic scale. Researchers at Trinity College, Dublin have discovered a technique which significantly improves the output of light from quantum dots, and also allows their light to be focussed and manipulated easily. Their findings are published today in the... view more... (2003-08-27)

Light, photosynthesis help bacteria invade fresh produce
Exposure to light and possibly photosynthesis itself could be helping disease-causing bacteria to be internalized by lettuce leaves, making them impervious to washing, according to research published in the October issue of the journal Applied and Environmental Microbiology.   view more (2009-09-29)

New NIST method improves accuracy of spectrometers
Measurements of the intensity of light at different wavelengths can be made more accurately now, thanks to a new, simple method for correcting common instrument errors.   view more (2005-06-17)

Measure the speed of light using Milky Way Stars®
Nothing travels faster than light - it only takes 8 minutes for it to reach the Earth from the nearest star, the Sun, which is 150 million kilometres away. Now anyone can measure this speed - with chocolate stars and a microwave oven! The experiment is described on a new Institute of Physics web resource for teachers about fun physics... view more...

Light activated anticancer drug targeted to DNA using cisplatin like sub-units
One of the most effective chemotherapy drugs against cancer is cisplatin because it attaches to cancer DNA and disrupts repair.   view more (2006-03-27)

Highways Agency congratulated for environmentally friendly lighting
Lighting that shines in a controlled manner rather than skywards, has resulted in the Highways Agency being congratulated by the House of Commons Science and Technology Committee recently. The Committee praised the Agency for forward thinking, and believes the high pressure sodium lanterns are a step in the right direction to reducing light... view more... (2003-12-01)

U of Minnesota researcher discovers the starting point of sun-induced skin cancer
According to a new study from the University of Minnesota, the earliest event in the development of sun-induced skin cancer may have been identified.   view more (2008-05-15)

Firefly Light Helps Destroy Cancer Cells
Could the gentle firefly turn out to be a potent weapon against cancer? In a new study, researchers from London inserted the firefly gene that activates bioluminescent light into modified cancer cells, hoping to set off a chain of events that has a proven track record at fighting the disease. This light source, known as Luciferin, caused the... view more... (2003-04-11)

Studying the fate of drugs in wastewater
Researchers at the National Institute of Standards and Technology (NIST) have published an interesting study that sheds light on the fate of a familiar pharmaceutical as it enters the waste stream.   view more (2005-12-27)

Next-generation microcapsules deliver 'chemicals on demand'
Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen.   view more (2009-10-29)

Light turns liquid
LIGHT can be turned into a glowing stream of liquid that splits into droplets and splatters off surfaces just like water. The researchers who`ve worked out how to do this say "liquid light" would be the ideal lifeblood for optical computing, where chips send light around optical "circuits" to process data. Liquid light sounds like a... view more... (2002-07-03)

Sunlight exposure plus low antioxidant levels may place older adults at risk for eye disease
A European study suggests that the combination of low plasma levels of antioxidants and blue light exposure from the sun is associated with certain forms of the eye disease age-related macular degeneration (AMD), according to a report in the October issue of Archives of Ophthalmology, one of the JAMA/Archives journals.   view more (2008-10-14)

'Tunable' network features coordinated frequency combs
A super stable fiber-optic network that can be tuned across a range of visible and near-infrared frequencies while synchronizing the oscillations of light waves from different sources has been demonstrated at the National Institute of Standards and Technology (NIST).   view more (2007-05-14)

Nano surfaces could slash cost of solar energy
Nanotechnologies which can artificially change the optical properties of materials to allow light to be trapped in solar cells could greatly reduce the cost of solar energy.   view more (2005-02-03)

Physics World Digest: August 2002 edition
Physicists see eye to eye with opthamologists Glaucoma is one of the leading causes of blindness in adults - yet over half of us who have the disease do not realise that we are suffering from the condition. While the disease can be treated if caught soon enough, early diagnosis relies on regular screening programmes that can be expensive and... view more... (2002-08-01)

Muffling noisy central heating systems
Droning noises generated by central heating boilers can aggravate good neighborly relations. Fraunhofer scientists have developed a compact sound attenuator for boiler exhaust vents. The active silencer employs electronics to damp noise emission. During the cold season, the droning sound of the central heating is just one of an assortment of... view more... (2002-03-05)
