Re: BIODEGRADEABLE

Thanks, bobjengr, glad you like the story. This has just been announced in R&D, so I doubt if they've gotten any sort of medical approvals yet, or it would have been mentioned. More details about Tufts' work may be available on their website, or in the (unfortunately for-pay) research article we give a link to in the article. Let us know if you find out!

BIODEGRADEABLE

Great post Ann.  To me, the most fascinating part is fact that the material is biodegradable.  It does its job then goes away—absorbed into the human "system".  Do you know how long Tuffs University worked on the project and whether or not necessary medical approvals have been awarded?  I would love to know what length of time was needed to develop this marvelous application.  Again, great post.

You're right, Ann, the emerging economies are young. But the mature economies have the medical needs, and the mature economies also have the development dollars. The againg population will create a growing need that will support medical developments.

Rob, I agree. I think there are a few factors driving developments like this, including an aging population (at least in the US, Japan and Europe, although the opposite trend is occurring in the ROW and it, in fact, trumps the aging trend in these three areas).

Thanks, Dave. I also noticed that the silk scaffold strength doesn't match up to the strength of bone, which was, after all, designed to do something silk was not. I often suspect that we may have to learn how to design new materials at the molecular level in order to make what we need out of non-original materials.

Interesting research

@Ann: Wow, another fascinating article.  Not only did the Tufts research group use a biological material, but they also used a bio-inspired principle of combining large fibers with microfibers.  It's also interesting that the fiber scaffolds that were most bone-like (i.e. the most rigid) were the most effective in promoting differentiation of stem cells into bone cells.  In other words, not only are they strong, but they also help the body repair itself.

On the other hand, it's a little humbling that the best scaffold material still had a compressive strength that is nearly an order of magnitude less than that of bone (13 MPa vs. 100 MPa).  Clearly, we have a long way to go before we can improve on what nature has, after all, taken billions of years to develop.

Nadine, there was no information about whether larvae are removed before the cocoons are boiled. It would be interesting to know if, when that is not done, that's for expediency or because it produces a better silk fiber.

Good point, Ann. We're going to see tons of these developments in the coming decade. The timing is perfect given the approaching medical needs of aging boomers.

TJ, this is designed to dissolve inside the body, as it is bio-compatible and biodegradable.

Thanks, Rob, I agree. I was really happy to see this. I especially like the cross-application aspect: silk has been used for years in sutures because it's biocompatible and biodegradable.

Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team 100 to make (about $161 US).
At Medical Design & Manufacturing Midwest, Joe Wascow told Design News how Optimal Design prototyped a machine that captures the wing-beat of a duck.
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
