Pinpointing the origins of SARS-CoV-2, and making vortex beams of atoms

Staff Writer Jon Cohen joins host Sarah Crespi to discuss the many theories circulating about the origins of SARS-CoV-2 and why finding the right one is important. Next, Ed Narevicius, a professor in the chemical and biological physics department at the Weizmann Institute of Science, talks with Sarah about creating vortex beams of atoms—a quantum state in which the phase of the matter wave of an atom rotates around its path, like a spiral staircase. This week’s episode was produced with help from Podigy.
