Fireflies' glow helps UT Southwestern researchers track cancer drug's effectiveness
DALLAS May 29, 2008 The gene that allows fireflies to flash is helping researchers track the effectiveness of anti-cancer drugs over time. UT Southwestern Medical Center researchers are among the first to show that a technique called bioluminescence imaging (BLI) can be used to determine the ...Sandia's microencapsulation project gives local entrepreneur warm glow
ALBUQUERQUE, N.M. Microencapsulation isn't a new technology, but it's always finding new applications.
