Single-stranded tiles (SSTs) made of short strands of interlocking DNA can be programmed to assemble themselves into precisely designed shapes, including letters, numbers, and emoticons. (Source: Wyss Institute at Harvard University)
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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
