With a headline like "Yoga Like Nanotechnology," I figured the article had to be a bad joke. But no: While addressing an organization in India, Baba Ramdev, reportedly a world-renowned yoga expert and self-described spiritual guru, gave a talk entitled "Bridging the Nanogap." In his presentation, he said, "Using yoga to treat a disease is just another example of using nanotechnology in medicine."

According to this report, Ramdev explained that "[j]ust as nanotechnology has the potential to send nanoparticles within the body system to seek out and treat afflicted parts; pranayam in yoga sends oxygen to the remotest parts inside the body which need oxygen for cure."

Now, I've never done yoga, and for all I know, certain yoga positions do help oxygen travel to various organs and help the body restore itself. That said, I do know a thing or two about nanotechnology. If you'd like to follow the swami's advice and invest in a few companies working to pit nanotechnology against human illnesses, I'd encourage you to begin with Harris & Harris (NASDAQ:TINY) and Arrowhead Research (NASDAQ:ARWR).

Harris & Harris, a Motley Fool Rule Breakers recommendation, has invested in handful of promising nanotechnology start-ups pursuing innovative health-care applications.
