Thom Graves MediaThe audience, several hundred biophysicists strong, was not expecting a James Brown impersonation. But there he was: Physiologist Yale Goldman, keynote speaker on motility at the Biophysical Society's annual meeting, doing his "asymmetric hand-over-hand motility dance with a limp" to tinny strains of "Papa's Got a Brand New Bag." And while Goldman, who eschewed Brown's trademark, over-the-top couture for understated, Ivy League-issue khakis and blue blazer, won't star on MTV any
