Two or three times a year most of us go through the
misery of the common cold.
That's not even counting the stomach bug and other
Todd Rider, a scientist at the Draper laboratory in
Massachusetts, is working on a way to cure viruses
by getting virus-infected cells to commit suicide
while keeping a person's healthy cells intact.
He calls it Draco.
DRACO is looking for this particular type of RNA that
is only made by a very broad spectrum of viruses and
it finds that and knows that the cell is infected.
He created draco by combining three molecules.
One invades cells in the body.
Another detects viral RNA, and a third causes the
infected cells to self-destruct.
Without the infected cells the virus cannot replicate.
Think about a burglar alarm inside every house.
Draco works by rewiring certain parts of that burglar
alarm to make them more effective.
