Heidi Bell, assistant professor in the Department of Human Performance Studies, was selected to discuss her research regarding tongue strength with Ira Flatow, host of NPR's Science Friday, from 2:06 to 2:19 p.m. tomorrow (Friday, Sept. 8). Bell's research suggests that tongue muscles (there are eight of them) can be strengthened just as any other muscles in the body, an important consideration as people age. Science Friday, a weekly science radio show is broadcast starting at 1 p.m. each Friday on KMUW 89.1.
