P: Streptomycin still looks like the most promising foe of tuberculosis, but Dr. Alfred Marshak of the U.S. Public Health Service found another likely-looking one: a yellow crystal extracted from California Spanish moss (not to be confused with the lacy Spanish moss that hangs from trees). It checks T.B. in guinea pigs, has still to be tested on man.
