Open Wide: Photonics Lights Up Endodontics
Photonics is making waves among the dental specialists known as endodontists – think root canals – finding success in the critical canal disinfection process and spawning a new opportunity for laser Raman spectroscopy. The goal of endodontic treatment is to save a damaged or infected tooth through a systematic process of shaping, cleansing and sealing designed to kill bacteria in the...
A Coherent Plan for Dental Health
Lasers are not by any means ubiquitous in dentists’ offices in the US, but their acceptance is growing in the States and beyond as they become more refined, as new applications are found, and...

Editorial
Make It So, Already
If the volume of words written and spoken about the development of a medical tricorder-type device is any indication of its imminent arrival, I’d say it’s only a matter of time before we can order one on Amazon. Such devices would save critical time in so many medical trauma situations – from accident and disaster scenes to the battlefield – it’s no wonder so much...

Blue seas at night, sea creatures’ delight
One-celled plankton have long been known to produce blue flashes in the sea at night, but no one has known quite how they do it – until now. The plankton, called dinoflagellates (Karlodinium veneficum), bioluminesce through a mechanism involving voltage-gated proton channels within their membranes, according to a study that showed that chemical or electrical events can open or close these...
