'LouseBuster' Instrument Shown to Kill Head Lice

University of Utah biologist Dale Clayton demonstrates the the latest prototype of the LouseBuster -- which he invented with students -- on his daughter, Miriam Clayton. The new, chemical-free treatment kills almost all louse eggs and enough hatched lice to prevent them from reproducing, effectively ending an infestation, according to a study in the November issue of the journal Pediatrics.
