In the future, sufferers of chronic pain may simply need to sip petunia tea or pop a petunia seed pill in order to alleviate their symptoms. These petunias would have been genetically modified to produce small, circular peptides very similar to conotoxins, produced in the wild by a family of marine molluscs called cone snails. (more…)
