In this episode, visit with Spencer Benson, Ph.D., and Yuan Lin, Ph.D., who are working with an herb called Rubricine to develop an herbal medication to treat infections. The benefit appears to be that the herb’s properties make it more difficult for bacteria to build resistance to the medications. In the second half of the program, meet Siba Samal, Ph.D., who is using a cutting-edge method called "reverse genetics" to develop a vaccine for Newcastle disease, an illness that effects poultry. His research is also providing a model to fight the human diseases, mumps and measles. From the Series:Researching Maryland
