The image shows the exoplanet HIP 65426 b in varying infrared light, revealing that it is a gas giant, contains no rocky surface and is thus uninhabitable. From the image, astronomers were also able to discern that the exoplanet is about six to …

Muhammad Samizadeh Nikoo—an electrical engineering PhD student at Ecole Polytechnique Fédérale de Lausanne’s POWERlab—recently discovered a brain-like learning ability in vanadium dioxide (VO2). When observing how long VO2 (an inorganic compound) takes to transition from one state to another, Nikoo found that it has “volatile memory.” To investigate, he administered electric currents through the material, noting how it changed phases while the current passed through …
