Hammed Aljohani, 5, shares what he’s discovered about fruit flies with his older brother, Ruwwad Aljohani, 8, with the help of Vanderbilt neuroscience graduate student Nicholas Smith on Saturday during the annual “Brain Blast,” a half-day of free, hands-on activities for children and adults co-sponsored by the Vanderbilt Brain Institute and Tennessee State University and held this year on the TSU campus. Brain Blast is part of Brain Awareness Month, which continues through March 29.
