LESSONS FROM BJORK(S): Robert Bjork, director of UCLA's Learning and Forgetting Lab, thinks locking yourself up in a room to cram is a bad way to store knowledge. Instead, he recommends a strategy called "interweaving"--a mix of exercises related to the core task at hand, and studying in different locations--as a better way to recall those pieces of info in different scenarios in the future. (Meanwhile, the Icelandic Bjork is embarking on an educational tour of her own to teach science and music while promoting her latest album.)
