Spying on a cellular director in the cutting room
Like a film director cutting out extraneous footage to create a blockbuster, the cellular machine called the spliceosome snips out unwanted stretches of genetic material and joins the remaining pieces to fashion a template for protein production.

Caltech-led team provides proof in humans of RNA interference using targeted nanoparticles
A Caltech-led team of researchers and clinicians has published the first proof that a targeted nanoparticle -- used as an experimental therapeutic and injected directly into a patient's bloodstream -- can traffic into tumors, deliver double-stranded small interfering RNAs, and turn off an important cancer gene using a mechanism known as RNA interference.
