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)
Lasers Penetrate Cancer's Gene Secrets
LIGHT SABRES and phaser guns may be the stuff of science fiction, but laser technology has brought an important step forward in our present-day understanding of cancer, a study reveals this week.* By using miniature lasers to probe pancreatic tumours, Cancer Research UK scientists have implicated three new genes in the development of the disease.... view more...

Laser Image Aimed at Achieving 85 Percent Reduction in Costs
An innovative laser imaging technique, developed with funding from the Office of Naval Research (ONR), could cut more than 7,700 man hours from the manufacturing cycle of the VIRGINA-Class Submarine (VCS). view more (2009-07-31)
NIST method may help optimize light-emitting semiconductors
Physicists at JILA have demonstrated an ultrafast laser technique for "seeing" once-hidden electronic behavior in semiconductors, which eventually could be useful in more predictable design of optoelectronic devices, including semiconductor lasers and white light-emitting diodes. view more (2006-02-17)
Laser Surgery Probe Targets Individual Cancer Cells
Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases. view more (2008-06-25)
First demonstration of new laser-driven accelerator technology
A team of UK scientists has used, for the first time, an extremely short-pulse laser to accelerate high-energy electrons over an incredibly short distance. Current accelerators can be hundreds of metres long, this is just a millimetre long. view more (2004-09-28)

Tiny infrared laser holds promise as weapon against terror
The difficulty of detecting the presence of explosives and chemical warfare agents (CWAs) is once again all too apparent in the news about the London bombings. view more (2005-08-08)
Scientists create metal that pumps liquid uphill
In nature, trees pull vast amounts of water from their roots up to their leaves hundreds of feet above the ground through capillary action, but now scientists at the University of Rochester have created a simple slab of metal that lifts liquid using the same principle-but does so at a speed that would make nature envious. view more (2009-06-03)
Laser treatment not effective in preventing vision loss for people with early AMD
According to a study that appears in the November 2006 issue of the journal Ophthalmology, researchers at the University of Pennsylvania School of Medicine and 21 other clinical centers have found that low-intensity laser treatment-thought to be potentially beneficial in slowing or preventing the loss of vision from age-related macular... view more...

Lasers, Tomatoes and Blood
The monitoring of blood flow in the skin is an important diagnostic tool in many areas of medicine. These include the diagnosis of diabetes and of various dermatological conditions, the assessment of burn and other wound damage, and the response of the vascular system to smoking and other drugs. view more (1998-09-01)
Smoking linked to blindness
Smokers are up to four times as likely to become blind in later life from age related macular degeneration (AMD) than non-smokers, but many remain largely unaware of this risk, warn researchers in this week's BMJ. AMD is the most common cause of adult blindness, which results in severe irreversible loss of central vision. One in five cases of AMD... view more... (2004-03-03)
Tiny spectrometer offers precision laser calibration
A tiny device for calibrating or stabilizing precision lasers has been designed and demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-05-14)
Holography and Laser Technology in Medicine
Bonn, 2002-11-18. From the 20th to the 23rd of November 2002 the caesar research center presents new medical applications for laser technologies at the MEDICA Trade Fair in Dusseldorf (Hall 12, Stand C32, Science Region Bonn). The scientists present a rapid method for three-dimensional facial topometry. Additionally, they introduce a C02 laser... view more... (2002-11-18)
CD player can process more information
The current application of CD-ROM techniques demands faster and better CD-players that can process more information. PhD Student Marco Dettori’s degree ceremony is on Tuesday 10 April. His research project resulted in a greatly improved controller for CD drives. “The large amount of information on for example a DVD, demands a much... view more... (2001-04-06)
Benchmark fetal surgery study finds timeliness to be critical factor in success of treatment
It's one of the biggest controversies in fetal surgery and the cause of heated debate among surgeons and maternal-fetal medicine physicians around the world: What's the best way to treat twin-twin transfusion syndrome (TTTS), one of the most common conditions requiring fetal surgery and the leading cause of mortality in twins? view more (2007-02-12)

Researchers measure field strength and density of ICF implosions
Scientists have identified for the first time two distinctly different types of electromagnetic configurations in inertial confinement fusion implosions that have substantial effects on implosion dynamics and diagnosis. view more (2008-02-29)
Have scanner, will travel
No train will travel where safe passage is not guaranteed. Shifted rails or a tree growing too close to the track is an accident waiting to happen. To clear the way for safer travel, a rapid laser scanner measures the clearance profile surrounding the train. We all need our own space - even a locomotive with cars. For this reason, rail operators... view more... (2004-02-03)
