Protein fishing in America: The movie
Proteins pass messages to other proteins much like fly-fishermen flicker their lines against water, or so a current leading theory holds. This vital exchange between single molecules has defied direct observation because that line-flicking and message-passing happen randomly at such a small scale. An instrument at the Pacific Northwest National Laboratory can reveal real-time interactions of single proteins, and its new results support the fly-fishing theory of protein communication.

Study shows that fluorescence spectroscopy can distinguish brain tumor from normal tissue
When neurosurgeons attempt to remove the deadliest type of brain tumor, glioblastoma multiforme (GBM) nothing is more important - or more challenging - than distinguishing normal tissue from tumor.
