Researchers have developed a faster, cheaper and simpler alternative to typical DNA origami fabrication, increasing the technique's accessibility and potential impact in industry and clinical settings.  Two physicists working out of the University of Florida and Pacific Northwest National Laboratory, Paul Johns and Juan Nino, conducted research to enhance global nuclear security by improving radiation detectors.  Hybrid organic-inorganic perovskites are especially successful, and they have been used in optoelectronic devices including solar cells, photodetectors, light-emitting diodes and lasers.  A new microscope breaks a long-standing speed limit, recording footage of brain activity 15 times faster than scientists once believed possible.  Engineers at Duke University have developed a method for extracting a color image from a single exposure of light scattered through a mostly opaque material.  Physicists from Nanyang Technological University, Singapore (NTU Singapore) and the Niels Bohr Institute in Copenhagen, Denmark, have devised a method to turn a non-magnetic metal into a magnet using laser light.  Physicists at EPFL propose a new "quantum simulator": a laser-based device that can be used to study a wide range of quantum systems.  The DESY accelerator facility in Hamburg, Germany, goes on for miles to host a particle making kilometer-long laps at almost the speed of light. Now researchers have shrunk such a facility to the size of a computer chip.  University of Michigan physicists have led the development of a device the size of a match head that can bend light inside a crystal to generate synchrotron radiation in a lab.  A new advance by researchers at MIT could make it possible to produce tiny spectrometers that are just as accurate and powerful but could be mass produced using standard chip-making processes.
