Scientists have designed a laser diode that emits what they say is the shortest-wavelength ultraviolet light achieved to-date, with potential applications in disinfection, dermatology, and the analysis of gas and DNA
Researchers have developed a new method to better model human stroke which uses artery-targeted photothrombosis. This shows a clear improvement on traditional methods by creating a larger penumbra for a longer amount of time while maintaining the practical results of the traditional model.
