Scientists in Japan design first optical pacemaker for laboratory research
The world's first optical pacemaker is described in an article published today in Optics Express, the Optical Society's open-access journal. A team of scientists at Osaka University in Japan show that powerful, but very short, laser pulses can help control the beating of heart muscle cells. view more (2008-05-28)
Dual-focus lenses cut thick metal fastest
V&S Scientific, the UK company that licenses the technology from the Force Institute in Denmark, says that demand for the dual focus lenses is beyond expectation, even though they cost much more than conventional optics for laser cutting. The company exceeded its 1999 sales projections for the lenses by the Spring, reports the July issue of Opto... view more... (1999-06-30)

Laser Therapy Offers Hope For Acne Sufferers (pp 1342, 1347)
UK research in this week's issue of THE LANCET suggests that single-dose laser therapy could dramatically reduce inflammatory facial acne for up to 3 months. Effective new treatments are required for people with acne; this common skin disease can be associated with social isolation, employment difficulties, and occasionally suicide. At present... view more... (2003-10-22)
MR-Guided Laser Effective in Treating Liver Tumors
A large-scale, 12-year study has found that laser ablation with magnetic resonance (MR) guidance is as effective as traditional surgery in the treatment of liver tumors in some patients. view more (2005-11-30)
Breakthrough in computer chip design eliminates wires in data transmission
Research slated to appear in the October 2 edition of the Optical Society of America's (OSA) Optics Express will unveil that researchers have created a new laser-silicon hybrid computer chip that can produce laser beams that will make it possible to use laser light rather than wires to send data between chips, removing the most significant... view more...

Highlights from Opto and Laser Europe, July 2000
Consultants and suppliers question train signal claims Claims made by the UK's rail operator Railtrack that its signal lights conform to the International Commission on Illumination's (CIE) recommendations have been questioned by its signal suppliers and external technical consultants. The allegations follow a story in last month's issue (OLE June... view more... (2000-06-23)
Cancer diagnosis - the Star Trek way
A small portable optical tool that can simply be pointed at the body to detect cancerous cells or reveal how body tissue is being affected by laser or cryogenic therapy could one day be the result of research being carried out by laser physicists at Imperial College. view more (2000-03-21)
Perforating aircraft wings with minute holes could make for more efficient flying.
One way to make aeroplanes fly more efficiently is to drill millions of tiny holes in the leading edges of the wings. Like the dimples on a golf ball this has the effect of reducing drag. However, producing these holes on a manufacturing scale is not yet commercially feasible. Researchers at Heriot-Watt University, funded by the Engineering and... view more... (2002-01-14)
