Polymer film could be used in artificial muscle and to power micro- and nanoelectronic devices. MIT engineers have created a new polymer film that can generate electricity by drawing on a ubiquitous source: water vapor. The new material changes its shape after absorbing tiny amounts of evaporated water, allowing it to repeatedly curl up and... Read more »

New sensor can detect four different molecules, could be used to program cells to precisely monitor their environments. Using genes as interchangeable parts, synthetic biologists design cellular circuits that can perform new functions, such as sensing environmental conditions. However, the complexity that can be achieved in such circuits has been limited by a critical bottleneck:... Read more »
