Roland Piquepaille writes "Researchers at UC Santa Barbara (UCSB) have built the world's first mode-locked silicon evanescent laser. But what is an 'evanescent' laser? It is a step toward 'combining lasers and other key optical components with the existing electronic capabilities in silicon.' In other words, this research work will provide a way to integrate optical and electronic functions on a single chip. As these evanescent lasers can produce stable short pulses of laser light, they will be useful for many optical applications, such as high-speed data transmission or highly accurate optical clocks."

brajesh writes to tell us that Skype has blamed its outage over the last week on Microsoft's Patch Tuesday. Apparently the huge numbers of computers rebooting (and the resulting flood of login requests) revealed a problem with the network allocation algorithm resulting in a couple days of downtime. Skype further stressed that there was no malicious activity and user security was never in any danger.

Roland Piquepaille writes "According to BusinessWeek, an Israeli startup, aptly named Deep Breeze, has developed a high-tech replacement for the 200-year-old stethoscope. This noninvasive device can draw, in seconds, an image of your lungs by listening to its vibrations. The Vibration Response Imaging (VRI) system could already be used in Israel, Europe and South Korea. Last month, the US Food and Drug Administration approved its introduction in the US. But don't expect to see one of these systems used by your local physician anytime soon. This VRI system will carry a price tag of over $40K."
