# gst: deep, super-resolution vistas through tiny tornadoes of magnetized plasma

<< To get the extremely high-resolution images vital to study new materials, microbes, and more, scientists often build microscopes based on optical vortices. >>

AA << devised a way to make optical vortices with 1000 times more power than previous methods. Their design uses strong, nonuniform magnetic fields to control plasmas, or ionized gases, to create the vortices. >>
