IBM and the Institute of Bioengineering and Nanotechnology in Shanghai have designed a new type of polymer that can detect and destroy antibiotic-resistant bacteria such as MRSA. The polymer nanostructures also prevent bacteria from developing drug resistance. Moreover, because of the mechanism by which the nanostructures work, they don’t affect circulating blood cells, and, unlike most traditional antimicrobial agents, the nanostructures are biodegradable, naturally eliminated from the body rather than remaining behind and accumulating in tissues.

After the computer known as Watson easily dispatched of the best two human Jeopardy! contestants in history, IBM announced that one of the first applications of their artificial intelligence technology would be in the medical field. We should soon expect virtual physician assistants in the exam room. At least one of my friends even speculated that the days of human doctors are numbered.
Is it possible that machines will replace humans in the doctor-patient relationship? I doubt it. According to a study done by the Mayo Clinic in 2006, the most important characteristics patients feel a good doctor must possess are entirely human. According to the study, the ideal physician is confident, empathetic, humane, personal, forthright, respectful, and thorough. Watson may have proved his cognitive superiority, but can a computer ever be taught these human attributes needed to negotiate through patient fear, anxiety, and confusion? Could such a computer ever come across as sincere?
I’m afraid some major calibrations might be needed to substitute artificial intelligence for an “ideal” physician. What do you think? Here’s an artist’s conception (read: farce) of how such an application in the examining room might play out. Click HERE to watch the medical cartoon.
If you’ve been watching Jeopardy! over the past couple days, you probably know that IBM’s highly-advanced artificial intelligence software, Watson, has been competing against Jeopardy!’s most successful contestants (and as of Tuesday night, took a commanding lead over the humans, despite having some trouble with United States geography).
Besides the amazing ability to power through “Daily Doubles” and answer random trivia in the form of a question, IBM researchers believe that Watson could revolutionize the healthcare industry. From diagnostics to informatics, Watson could quickly search through medical records, clinical documents, and research information for precise answers that would benefit both doctors and patients.
Check out the video below to see physicians explain how Watson’s technology could transform medicine.
Also watch the TED.com webcast of Dr. David Ferrucci (Principal Investigator of the DeepQA/Watson project at IBM), Dr. Herbert Chase (Professor of Clinical Medicine at Columbia University School of Physicians and Surgeons), and others discussing the Jeopardy! challenge and the impact the technology behind Watson could have on society.
It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
