French president Emmanuel Macron recently announced that Leonardo da Vinci’s famous Mona Lisa painting will be moved to her very own room at the Louvre, as part of a plan to renovate the iconic museum. And that got us thinking. Once the crowds have gone home every night, the Mona Lisa will be all by herself, with no other paintings to smile at enigmatically across the room. So this week, we are talking all things isolation. We start things off by finding out about a key cognitive skill that may ...
