High Speed Laser Kills Virus Without Damaging Healthy Cells

A new high speed pulsing laser developed by Arizona State physics professor Kong-Thon Tsen and his son Shaw-Wei Tsen, a pathology student at Johns Hopkins, has succeeded in killing a common virus without damaging the healthy surrounding cells. The laser utilizes the principle of "forced resonance" by vibrating the shell of a virus to "crack" it. Plus, tests have proven that it is possible to break down the shells at energies far lower than those needed to damage surrounding T-cells.

Since these ultrashort-pulse lasers or USPs don't generate a lot of heat, they are far gentler than conventional lasers, which may open up the possibility of using them to eradicate viruses in stored blood. The duo is currently testing the laser on HIV and hepatitis, which could be truly groundbreaking if successful. Will this physics professor and his biologist son restore my faith in medical science? Only time will tell.

TechFaith Launches "World's First WCDMA/GSM Dual Mode Phone"

China's TechFaith Wireless Communication Company has developed what they are calling the "World's first WCDMA/GSM dual mode phone." The "Twins" phone, as it has been dubbed, allows users the option of loading one WCDMA card and one GSM or loading dual GSM SIM cards. That means it would no longer be necessary to switch out SIM cards or carry around two phones for calls on both business and personal lines.

Other features include: a 2.0 megapixel camera, 2.8" touch sensitive TFT-LCD display, 256MB/64MB ROM memory, MP3 and MPEG4 player, WCDMA modem, Bluetooth, and video call capabilities. Two models will be available the "Dragonfly" and "OMAP' with the latter having a faster CPU and tri-band network support instead of quad-band. Naturally, no pricing information has been released, which is just as well seeing as how this product is unlikely to make its way to the states anytime soon.
