In recent studies at Purdue Universtiy, researches have found that molecular machines could be used to treat diseases. For example, molecular machines could be used to treat cancer and HIV. The researches will watch to see how the molecular machines bind and interact with other molecules. Eventually, they may be able to manipulate the machine so that it can remove the "malfunctioning gene." These molecular machines are called Group 1 introns. I think these molecular machines are particularly interesting since they can be used to treat diseases that affect a huge percent of the population.
