Chameleons display beautiful colors that result from the way light diffracts off billions of tiny nanoparticles in the skin. These animals need only to stretch their skin to trigger a color change in situations such as blending in with the surroundings, signaling to a potential mate, or adjusting to changes in temperature (1). Creating materials with such adaptive response has been a far-reaching goal for fundamental and applied sciences (2). Metamaterials—artificial materials with structure-dependent properties—have been particularly successful toward this goal. However, modulating multiple functionalities in such materials has remained largely unexplored. On page 1031 of this issue, Smart et al. (3) report a robot the size of a cell (~10 ?m) that can simultaneously change its shape, locomote, and manipulate light through diffraction just like a chameleon. These robots may one day be deployed into complex environments to perform detection and sensing tasks.
期刊介绍:
Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research.
Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated.
Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
