With a little practice on a computer or iPad—25 minutes a day, 4 days a week, for 2 months—our brains can learn to see better, according to a study of University of California, Riverside baseball players reported in the Cell Press journal Current Biology on February 17. The new evidence also shows that a visual training program can sometimes make the difference between winning and losing.

Epigenetic regulation required to ensure correct number of chromosomes
