This is fascinating new technology, Ann. I would imagine one of the applications could be targeting chemotherapy to the cancer instead of having to broadcast it to healthy cells as well as cancerous cells.
Isn't this amazing? Targeted drug delivery is definitely one of the possible apps the researchers have in mind, and if that could be done for chemotherapy it would make a lot of people healthier and happier.
Thanks williamlweaver, glad you liked the article. Self-assembled devices is becoming quite an an active area of research. I have read Crichton's PREY: pretty scary stuff, in fact I found it his scariest so far because it's so believable, perhaps even inevitable. Thanks for the link to your swarms article--another area of research that's getting a lot of play, especially in robotics.
University of Southampton researchers have come up with a way to 3D print transparent optical fibers like those used in fiber-optic telecommunications cables, potentially boosting frequency and reducing loss.
The first ASME Additive Manufacturing + 3D Printing Conference (AM3D) will be co-located with the organization's International Design and Engineering Technical Conferences (IDETC) and Computers & Information in Engineering Conference (CIE), Aug 2-5 in Boston.
