“Forever chemicals” that don’t break down naturally pose a serious pollution problem to both humans and the environment. Northwestern University, University of California at Los Angeles, and Tianjin University scientists have developed a promising new method to decompose these chemicals (perfluorocarboxylic acids) into benign products.
By using pixel analysis and magnification, National Taiwan University researchers can use a smartphone to detect narrowed arteries in the neck which are a risk factor for strokes. The team analyzed videos taken with a smartphone to look at changes in the pulse rate in the neck arteries which can identify blockages.
