This article describes attaching a drug molecule to a molecule from the rabies virus that enables the drug to cross the blood-brain barrier. This suggests a possible danger if the ability to produce the molecule could be transferred to the genomes of disease organisms in the wild. If the field of genetic engineering for drug […]
