Give Angela Belcher's viruses a hard hat...because the MIT materials engineer is putting them to work in construction.  Evolution has taught biological creatures how to build the most complex chemical structures on Earth, and to efficiently piece them together atom by atom in an environmentally-friendly way.  Humans can't match such precision engineering.  So Belcher is handing the viruses genetically engineered DNA blueprints she hopes will instruct them on how to self-assemble finely-crafted computer wires, and even clothing threads, that could repair themselves.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
