white is so 2003

scientists have discovered a positive correlation between the amount of gray matter (ie somas, the bodies of neurons) in one's brain to his/her intelligence!

i wonder the impact of this study, if results are replicated and confirmed. finding such a direct link seems like it obviates the need for IQ tests in a way - MENSA can now recruit based on soma count. exclusive schools and competitive companies may someday make decisions in part based on your brain scan.

now we need to answer why some people have more gray matter and others have less, and if there's any way to increase that.

another fascinating outcome: it's related to gray matter levels all over the brain, not just in one particular "smart spot." so... intelligence is distributed, making it harder to damage, which is good news.
