Top 10 Medical Breakthroughs

March 16, 2012 2 comments

Sorry for the delay between posts; life ambushed me for a few weeks there.

I haven’t talked about general breakthroughs in medicine recently, and I have a considerable backlog of cool stories on the topic, so let’s explore that a bit today. These breakthroughs aren’t necessarily transhumanist in nature, but they certainly all contribute to the general goal of better healthcare and are but a few steps away from some truly amazing technologies. So, without further ado, the Top 10 Medical Stories in My Queue:

10) The explosion of personalized medicine. The Wall Street Journal wrote a piece earlier this year about the idea of a “doctor in your pocket.” The idea is to have cheap, quick, accurate medical screening on a device that people can carry with them. Daniel Kraft has been very vocal about the explosion of this sort of technology in a limited sense, and Peter Diamandis recently announced an X-Prize for essentially the same concept; a lab on a chip that can diagnose a patient better than a group of board certified physicians. While diagnosis itself is not necessarily transhuman, clearly other transhumanists are interested in the idea, and if successful this sort of technology ought to keep people healthier for longer. With a $10 Million prize pool, there ought to be plenty of incentive to stuff Watson into a cell phone and make med students everywhere cry crocodile tears. The next step: An AI doctor in every house.

9) Likely to be included in these new personalized medicine machines: A cancer sniffing sensor for early detection. Gizmodo has a great article detailing what NASA’s been up to recently, including sensors that can detect toxins in the air and cancer. The really cool thing about this sensor is that it’s virtually production ready and can be attached to a cell phone right out of the box; that is, this isn’t a theoretical device, it’s all but here. Despite all the grumping about the government that frequently goes on, two federal programs (the Department of Homeland Security is the other) are pushing hard to get this technology into circulation. DHS, however, is mostly interested in the toxin and bomb chemical detecting properties while, for our purposes, the cancer detecting ability is probably more interesting (although if bomb making chemicals -are- detected near my cell phone, I sure wouldn’t mind a heads-up!) I don’t know what technology this sensor is using exactly, but it seems reasonable to include the sensor that MIT recently reported on that detects lung cancer through a breath test at an astounding 83% accuracy. There is room for improvement, as trained dogs can detect lung cancer with 98% accuracy, but as Gizmodo quipped, at least you won’t have to carry a Labrador around in your pocket.

8) Intelligent pills. Nature ran a story about them earlier this year, and both Scientific American and Pop Bioethics picked up the story long before I got around to it. The pills will have included along with the medicine a placebo that houses a small sensor. When the sensor interacts with stomach acid, the current will transmit information a very short distance; ideally to a Band-Aid-like device that can be worn on the skin and will measure heart rate, respiration, temperature and the like. This skin sensor, in turn, could wirelessly transmit health information to your doctor, allowing them to check in on your vitals without you needing to visit the office. If you frequently forget to take your pills, (a “problem area” in current medicine) your doctor (or, more likely, a digital secretary) can give you a quick call to remind you. Other pills that include cameras and other sensors are also in development, though those probably wouldn’t be used outside of particular contexts.

7) Wirelessly controlled ‘pills’. Science Daily posted an article about a month ago claiming that MicroCHIPS Inc. successfully tested a device that, once implanted into a patient, can deliver medication when it receives a wireless signal to dispense the drug. The device delivered amounts of the drug comparable to an injection (without needles, which I’m a fan of). Like the pills that alert the doctor when they’ve been taken, these devices help to ensure patient compliance with the doctor’s proscribed drug regimen. Unlike those pills, these devices can automatically deliver the proper drug dose, requiring the patient to neither swallow pills nor suffer injections. Although the initial device only carried 20 doses of the drugs, the final product ought to have hundreds. Further clinical trials will follow.

6) Continuing the pill trend, scientists are working on a special type of aspirin that doesn’t cause ulcers. Oh yeah, and it seems to fight cancer, too. In mice, at least, the drug fights colon, lung, breast, prostate, pancreas and blood cancers. Although the drug seems years away from human clinical trials, the lack of side effects and the bolstered cancer fighting properties show a lot of promise for the future.

5) Rounding out the pill discussion, researchers at Oxford University have discovered something curious about common beta-blockers, normally used to treat heart disease. They seem to also lesson racist associations. Although the sample size was small (18 white college students) the results occurred at a “statistically significant” rate as compared to those who received the placebo. The current theory is that the beta blockers affect the portion of the central nervous system that regulates fear and emotional responses. If the study is repeatable, interesting ethical questions arise about medicating out racist beliefs.

4) Chips for humans. MSNBC reports that the FDA recently approved an RFID chip for humans. Although similar technology has been used for years in pets to help reunite lost pets and their owners, human trials go rather a lot more slowly. There’s also some security issues to work out; RFID isn’t the most secure technology in the world (though it does take someone with some know-how to get to the data, and they need to be in fairly close proximity.) Ultimately, I imagine these sorts of chips will carry a lot more than patient information; credit card info, for instance, has been tried elsewhere in the world and offers a unique way to pay. Either the cost will have to come down from its $150-$200 price point, or the functionality is going to have to drastically increase to justify the costs.

3) Someday, we might be able to replace limbs with bionic equivalents that don’t break, in the meantime we’re stuck with the bones we have. Well, that and some new fracture putty if the Department of Defense has their way (those pesky government types again!) The DoD has commissioned research that already is beginning to bear fruit; the fractures bones of rats healed enough within two weeks that they were up and running around again. Next step; pigs and sheep (sheep bones have already been restored within a month.) Following those trials, the putty may be farmed out to the university veterinarian clinic and, if that goes well, to human trials afterwards. It’s not quite the nutrient bath from the movie Wanted, but it’s better than a cast for months.

2) While your bones are being healed by putty, the doctors might as well patch up your internal organs with some new gummy adhesive. Researchers from UCSD have developed a self-healing gummy (meaning the gummy repairs itself when it’s torn or broken) that becomes super adhesive when it comes into contact with acid; acid like that, say, that resides within the stomach. Perhaps the gummy will be useful for organs other than the stomach, but it seems well suited already to help treat stomach wounds.

1) Finally, for the poor sap that’s -really- undergone some punishment, there’s one last piece of tech that’ll help put Humpty Dumpty back together again. San Diego start-up company Organovo is printing muscles, layer by layer, and then placing it into a mold that allows the muscle to grow into something just like that which comes out of a human being. So far, Organovo has printed cardiac muscle, blood vessels, and lung tissue. Right now the company is focusing on creating tissue identical to natural human tissue so that scientists can experiment on the tissue without having to experiment on attached humans, but it hopes to use the same technology to print whole organs for transplant in the future. Between these last three technologies, then, even the worst accident victim ought to be in pretty good shape in the near(ish) future.

Thanks for sticking with me through the hiatus; the next post ought to be coming more quickly next time.


Some Quick Thoughts (And A New Format)

December 24, 2011 10 comments

After an extended absence, I’m pleased to bring boydfuturist back in a new format. Like many other bloggers, I struggle with finding a nice balance between content and regular publishing; the more in depth the post, the more time it takes to write something worth reading. The amount of time that it takes me to come up with a lengthy, thoughtful post would work great for adding to a technology site that has multiple contributors, but makes it difficult to sustain a regular publishing schedule when I’m the only author. Up until now I’ve had something of a dual online identity; here at boydfuturist I’d publish lengthy thoughts on technology, legal issues, and transhumanism generally and on my personal Facebook account I’d publish links or short comments to a handful of technology articles every day. Sometimes it feels like I’m spamming my friends with links and quick comments about tech articles.

It occurs to me that these two problems can solve each other. On on hand, I have too little content and on the other, too much. So, for the new year, I’m going to try posting multiple times per week in a digest format; the most interesting articles I’ve read during the last day or few days along with some short commentary. Since I push through boydfuturist updates to Facebook, this should reduce my Facebook posts to once per day (plus the non-tech stuff I post) and dramatically increase my posts here. When inspiration strikes me, I’ll post more lengthy updates on here as well. Best of all, this will give me (and my readers) a searchable index of articles for later access.

I was on the road for the holidays yesterday, so I didn’t get a chance to read many articles. Here’s a few from this morning:

TechEBlog has a great article about the world’s first gaming laptop. Of course, many of us have gamed on laptops before (I use my Gateway for small stuff right now) but the hardware packed by this little guy is truly impressive. It’s certainly not the cheapest option, but if you really must be the 1337est dude(ette) on the net, this laptop should provide a lag-free experience. People who really know their Hollywood geek roots might appreciate that this Razer Blade shares a name with two of the characters from Hackers, who undoubtedly would have loved to have this piece of equipment.

The Johns Hopkins Bloomberg School of Public Health has demonstrated that it’s possible to genetically engineer mosquitoes such that they’re immune to malaria. As the article says, roughly 800,000 people per year, many of them children in Africa, die from malaria each year. This is another great example bleeding edge of technology helping to cure problems, and not just for the wealthy.

Finally, Gizmodo pushes through an article that I (as perpetually terrified dental patient) really appreciate: University of Missouri affiliated scientists have created a plasma toothbrush that is supposed to painlessly clean cavities in roughly 30 seconds, and improves the surface for the filling that goes in afterward. With some luck, by 2013 going to the dentist for routine cleanings and (the hopefully rarer) cavity fillings will be a much less traumatic experience.

Happy Holidays, everyone!
