There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Winter is coming, and if you tend to feel sluggish or sad during those dark, dreary days of the season, it could be Seasonal Affective Disorder (SAD) to blame. The symptoms mimic those of regular depression. Shorter days and a lack of sunlight can cause a dramatic dip in serotonin, the body's natural mood stabilizer. Paul Verhaeghen, professor in the School of Psychology, suggests light therapy by using a light box or lamp with 2,500-10,000 lux. Using it one hour a day, preferably first thing in the morning, simulates natural sunlight and can increase energy.
