This week, as we've watched news and trends on brain matters, we've seen some fascinating studies and perspectives about how to bolster memory, make mundane tasks more fun, and improve decision-making. Here's a sampling:

Fonts of remembrance
You may think you like reading in easy-to-read fonts, such as Arial, but it turns out that people remember information better if they have to think about it harder.
