Compact, wavelength-on-demand Quantum Cascade Laser chip offers ultra-sensitive chemical sensing
Engineers from Harvard University have demonstrated a highly versatile, compact and portable Quantum Cascade Laser sensor for the fast detection of a large number of chemicals, ranging from infinitesimal traces of gases to liquids, by broad tuning of the emission wavelength. view more (2007-12-04)
Peptic ulcer surgery increases the risk of pancreatic cancer
Peptic ulcer surgery seems to increase the risk of developing pancreatic cancer, finds research in the Journal of Clinical Pathology. view more (2002-04-25)
New laser research could improve oil exploration success
CSIRO Petroleum and German-based research centre Laser Zentrum Hannover eV (LZH) are collaborating in a project that could save millions of dollars in oil exploration and introduce new Australian geochemical and petroleum analysis techniques to Europe. view more (2005-02-06)
Controversial "beating heart" method proves better than standard procedure
Patients needing second-time or "re-do" heart surgery have a new safer alternative. New findings show that an "off-pump" surgical procedure is performed safely and has improved outcomes for patients than traditional methods. view more (2004-09-26)
Scientists at the University of the Basque Country succeed in cooling solid material with laser
A team of researchers at the University of the Basque Country (UPV/EHU) have experimentally demonstrated something that other scientists have been trying to achieve for decades: the cooling of erbium-doped materials with laser light. view more (2006-07-27)
LIGHTNING PROTECTION ... JAMES BOND-SYLE
A leading expert from Staffordshire University is helping to produce a James Bond-style device which will protect people and buildings from lightning strikes - using a laser beam and a mirror. view more (1999-12-16)
German Science Council Recommends International Accelerator Project TESLA
The German Science Council, an agency of the German government, assessed the TESLA project planned by the research center DESY in cooperation with international partners to, be worthy of support under certain conditions. The assessments of nine appraised large scale facilities for basic research in the natural sciences have been published today.... view more... (2002-11-18)
World's fastest camera relies on an entirely new type of imaging
Ultrafast, light-sensitive video cameras are needed for observing high-speed events such as shockwaves, communication between living cells, neural activity, laser surgery and elements of blood analysis. view more (2009-04-30)
Lasers spark new paths in radio-isotope transmutation - Scientific breakthrough in the transmutation of isotopes
Collaboration between the European Commission's Joint Research Centre (JRC) DG, the University of Jena (Germany), the University of Strathclyde (UK), Imperial College (UK), and the Rutherford Appleton Laboratory (UK) has led to the transmutation of long-lived radioactive iodine-129 into short-lived iodine-128 using very high intensity laser... view more...

Informed Consent Does Not Seem to Influence Decision-Making Process For Cataract Surgery
Informing patients of the risks of cataract surgery as part of the informed consent procedure one day before surgery does not seem to influence patients' decisions to have the procedure, according to an article in the January issue of The Archives of Ophthalmology, one of the JAMA/Archives journals. Cataract surgery is the most frequently... view more... (2004-01-08)
K-State physics lab becoming a frontrunner in ultrafast laser research
For decades, the J.R. Macdonald Laboratory at Kansas State University has been known worldwide as a center for atomic collision physics using particle accelerators. Now, researchers at the lab are working toward making it known for ultrafast laser science. view more (2008-10-29)
Women with cosmetic breast implants more likely to commit suicide
Women who undergo cosmetic surgery for breast augmentation are more likely to commit suicide than women from the general population, finds a study in this week's BMJ. Researchers identified 3,521 Swedish women aged 15-69 years who had had breast implants between 1965 and 1993. They compared the observed number of deaths with the expected number of... view more...

Research Paper Illuminates How Light Pushes Atoms
A research paper published in the 18 August edition of the journal Physical Review Letters reveals a new effect in the fundamental way that laser light interacts with atoms. view more (2006-08-21)
Laser etching safe alternative for labeling grapefruit
Laser labeling of fruit and vegetables is a new, patented technology in which a low-energy carbon dioxide laser beam is used to label, or "etch" information on produce, thereby eliminating the need for common sticker-type labels. view more (2009-11-04)
Beating Heart Bypass Surgery Reduces Postoperative Complications...
Results of a study in this week's issue of THE LANCET suggest that coronary artery bypass graft (CABG) surgery done on the beating heart reduces the risk of short-term complications compared with conventional bypass surgery. CABG surgery on the beating heart (off-pump surgery) is increasingly being used when restoring coronary artery blood flow as... view more... (2002-04-04)
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)
Radiation after surgery doubles survival time for some lung cancer patients
Patients with lung cancer that has spread to mediastinal lymph nodes - located between the chest, breastbone and spine - who receive radiation after surgery and chemotherapy live twice as long as patients who do not receive radiation after surgery. view more (2006-11-07)
Use of hydrocortisone reduces incidence of atrial fibrillation after cardiac surgery
Patients who receive corticosteroids after cardiac surgery have a significantly lower risk of atrial fibrillation in the days following the surgery. view more (2007-04-11)
NASA Goddard Shoots the Moon to Track LRO
On certain nights, an arresting green line pierces the sky above NASA's Goddard Space Flight Center in Greenbelt, Md. It's a laser directed at the moon, visible when the air is humid. No, we're not repelling an invasion. Instead, we're tracking our own spacecraft. view more (2009-09-25)
Surgery remans an option for advanced lung cancer
In recent years, oncologists have debated whether patients with a certain type of advanced lung cancer would benefit from surgery. view more (2009-07-27)
