In addition to explaining the process of growing bioengineered organs, valves, and tissues, he also demonstrates how he’s using printing technology to fabricate body parts and even print skin tissue directly onto a patient’s wound. Other highlights of the talk include a live demo of a kidney-shaped mold being printed on the TED stage, and a reunion with a young patient who was one of the first recipients of a bioengineered bladder from Dr. Atala’s lab. Be sure to also check out Dr. Atala’s talk from TEDMED 2009… Additional...

Following human testing and FDA approval, devices such as these could replace similar systems that are external to the body with a needle attachment that pierces the skin to take measures. Combined with potential transdermal or intranasal insulin administration, this technology could lead to less sticking and poking of people with diabetes.

Their method makes use of nanopatches, which are fingernail-sized dermal patches with microscopic projections on their surface that hand vaccine off directly to the antigen-presenting cells just below the surface of the skin. The scientists’ recent work in mice has shown that an immune response equivalent to that achievable by needle and syringe can be reached using 100 times less vaccine. Not only does the nanopatch appear to be a more effective delivery method, it’s also cheaper to produce and doesn’t require refrigeration, adjuvants or multiple doses.

This is what I would call a faith-based initiative, in this case, faith in the technological fix. DHS could certainly use some help. It's one of the most clueless and incompetent agency in the federal government. But I don't think the answer to the problem is going to be found in nanotechnology, computer science or micrcomputer circuitry: The DHS noted that the cooperation between its departments and the science community has already resulted in major innovations in developing state-of-the-art screening, bio-threat detection and other technologies.

One of the many things that is exciting about this century’s palpable heartbeat is a noticeable and rightfully unabashed effort by providers of medical and health care (and many others concerned) to wear their sneakers once again, run around, jump up and down, and explore further how patient care is delivered. The resulting new and wiser approach includes the actual patient in the team—having a more active role in the process.

Sometimes it's obvious -- sort of. I remember having to make a daily trip from New York to Bellevue Hospitals in New York down FDR Drive. At one spot the three southbound lanes suddenly widened into five lanes because of some construction and then, after about 100 yards, narrowed again to three lanes. If you didn't know better you'd think the extra capacity of the roadway wouldn't be a problem but in your mind's eye you can see exactly what happened. All those cars that filled up the extra space had to reconverge to three lanes. The roodway aneurysm caused a terrible mess. More often, though, the cause isn't so clear.

If attacked, the swarm splits, merges and splits again, then comes back together. They don't just scatter, literally to the four winds. This kind of emergent behavior -- where local interactions produce global patterns -- has attracted scientists. Statistical physicists have been particularly interested, as this behavior mirrors what goes on when liquids boil or ice melts. Well, maybe not actually mirrors it.
