Crippled by multiple sclerosis, the lab mice's hind legs and tails were limp with paralysis, but Lisa Tostanoski had an idea about how she could treat them.
With a tiny needle, the doctoral student at the University of Maryland, College Park injected the mice with a dose of time-released medicine. Two weeks later the mice were scampering around their cages.
