At TED Rachel Armstrong researches construction materials that can be "manipulated to 'grow' architecture. In the future, cities may be able to replace the energy they draw from the environment and respond to the needs of populations." She says: "Scientists need to work outside their own areas of expertise to make new technologies that are pertinent to the 21st century and to collaborate, both with other scientific disciplines and the arts and humanities." S.K.I.N. couldn't agree more. Is this trend growing in science and the arts?
