It has long been known that certain psychoactive chemicals, found in such plants as the peyote cactus and diviner’s sage, enhance access to other planes of awareness. (Hence the old saw, “Reality is for people who can’t handle drugs.” Needless to say this comes with risks as well.) More recently, pills have revolutionized brain function among the mentally ill, beginning with the discovery of chlorpromazine in 1950. Now, drugs that enhance mental functioning in healthy people are becoming known and - increasingly - used. We are in the midst of a series of discoveries that will progressively enhance mental abilities. Alpha-CaM kinase II causes remembering a bad memory to erase it, at least in mice. Credible evidence exists for other biomolecular approaches to cognitive enhancement, some listed in the table. Join discussion...

Virtual Reality (VR) has advanced to incredible heights. For those who haven’t kept up with the gaming scene, the newest game renowned for impressive graphics is Fallout 3.

This past week, Stephen Oesterle, an executive at Medtronic gave a sobering keynote speech on the future of medical devices—and, if you’re in the medical device industry, the news wasn’t good. According to the Wall Street Journal’s Health Blog, Oesterle was quoted as saying, “When biotechnology gets it right we’re finished. Because it’s restorative, not palliative as device are.” If the message still wasn’t clear to his audience, he then added, “It’s done. [Medical] devices ultimately are done.” Join discussion...
