(Phys.org)—A team of researchers with members from several institutions in Japan has found a way to allow for using scanning electron microscopes (ESM) on living insects—encase them in a nanosuit. In their paper published ...
Inspired by the paper-folding art of origami, chemists at The University of Texas at Austin have developed a 3-D paper sensor that may be able to test for diseases such as malaria and HIV for less than 10 cents a pop.
