Laser cancer treatment and Martian imaging
Can laser light be used to treat cancer patients? Why is the search for Martian water so important? These questions may appear to be unconnected, but they actually have more in common than you might think. Both subjects will be tackled at free public talks held at Cardiff International Arena on Tuesday 3 and Wednesday 4 September. The talks show... view more... (2002-08-21)
A sonic boom in the world of lasers
It was an idea born out of curiosity in the physics lab, but now a new type of 'laser' for generating ultra-high frequency sound waves instead of light has taken a major step towards becoming a unique and highly useful 21st century technology. view more (2009-06-18)
Fine-tuning lasers to destroy blood-borne diseases like AIDS
Physicists in Arizona State University have designed a revolutionary laser technique which can destroy viruses and bacteria such as AIDS without damaging human cells and may also help reduce the spread of hospital infections such as MRSA. view more (2007-11-01)
Dangerous printer particles identified
The identity and origin of tiny, potentially hazardous particles emitted from common laser printers have been revealed by a new study at Queensland University of Technology. view more (2009-02-11)
Ultrafast lasers take 'snapshots' as atoms collide
Using laser pulses that last just 70 femtoseconds (quadrillionths of a second), physicists have observed in greater detail than ever before what happens when atoms collide. view more (2005-10-21)
Helia Wraps-up Optical Coatings
A new Scottish multi-million pound photonics company is geared up for the future of telecommunications after securing a seven figure private investment deal. The investment has allowed Helia Photonics Ltd, a Heriot-Watt University spin-out to purchase the coatings division of Terahertz Photonics in a technology transfer deal, and say they are... view more...

Topical Papers in Biochemical Journal - Selective determination of mitochandrial chelatable iron in viable cells with a new fluorescent sensor
This paper by Petrat and colleagues marks an important advance in our understanding of the regulation of iron in the human body. Real-time changes in the concentration of the ionized form of iron (Fe2+) can now be monitored within the mitochondria of living cells for the first time, thanks to the technique described in this article. For some... view more... (2002-02-08)
Photodynamic therapy: an effective treatment for head and neck cancers
A therapy that activates light sensitive drugs represents a major advance in the treatment of head and neck cancer, a consultant surgeon said today. (Monday 22 October 2001) Known as Foscan photodynamic therapy (PDT) 1, it is an "effective and well tolerated treatment" and can be administered without surgery, said Mr Colin Hopper of the National... view more...

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)
Should children undergo surgery without a long period of fasting after feeding?
Blood glucose levels in a lot of patients fed normal liquid food (NLF) and a high calorie diet (HCD) were high. view more (2009-10-29)
Thermometer For Plasma
St. Petersburg researchers have designed an original thermometer for fast-moving electrons in thermonuclear reactors. The laser beam in this device is used to instantly determine the temperature of burning hot plasma, at frequencies required for precise diagnostics. This device is a further step forward to controlled nuclear fusion. The device... view more... (2003-09-05)
Nine Countries Plan to Participate in the XFEL
An important milestone has been reached on the way towards the realization of the European X-ray laser XFEL: With France, Germany, Great Britain, Greece, Italy, Poland, Spain, Sweden, and Switzerland, nine countries have signed a Memorandum of Understanding in which they agree to jointly prepare the foundation of the facility. "Even if this... view more... (2005-01-24)
Improved planning and perfomance of surgery - caesar research center at the Medica in Düsseldorf
Bonn research center caesar is presenting current medical technology projects at the "Medica 2004" in Düsseldorf (Hall 13, Stand C12) from November 24 - 27, 2004. Scientists support surgeons with innovative computer and laser technology in the planning and performance of operations. At the trade fair they are demonstrating a laser... view more... (2004-11-22)
Astronomers use laser to take clearest images of the center of the Milky Way
UCLA astronomers and colleagues have taken the first clear picture of the center of our Milky Way galaxy, including the area surrounding the supermassive black hole, using a new laser virtual star at the W.M. Keck observatory in Hawaii. view more (2005-12-21)
NIST releases new standard for semiconductor industry
A wide range of optical electronic devices, from laser disk players to traffic lights, may be improved in the future thanks to a small piece of semiconductor, about the size of a button, coated with aluminum, gallium, and arsenic (AlGaAs). view more (2006-10-13)
Million pound study to help prevent blindness
A one million pound award to Cardiff University from the Medical Research Council is enabling researchers to conduct the world's most wide-ranging study into one of the body's most intriguing components - the cornea of the eye. At the front of the eyeball, the cornea is the transparent 'window' through which we see the coloured iris and the pupil.... view more... (2001-07-05)
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)
Lasers in car manufacture
Lasers play a key role in modern production - for such tasks as cutting sheet metal to size, welding containers and trimming circuit . But their potential is far from exhausted. The automobile industry is playing a pioneering role in the introduction of new laser types and machining processes. The Fraunhofer Institute for Laser Technology ILT in... view more... (1999-07-01)
New Quantum Cascade Lasers Emit More Light Than Heat
Northwestern University researchers have developed compact, mid-infrared laser diodes that generate more light than heat - a breakthroughs in quantum cascade laser efficiency. view more (2010-01-12)
SUBSTANTIAL INCREASE IN DEATH RATE AFTER BYPASS SURGERY FOR PEOPLE WITH ANAEMIA (p 1749)
Anaemic patients undergoing coronary artery bypass surgery could have up to a five-fold increased risk of death in the days after surgery compared with patients who have normal haemoglobin concentrations, suggest authors of a research letter in this week's issue of THE LANCET. People with anaemia (individuals with a haemoglobin concentration of... view more... (2002-05-15)
