Nature: Judging by the torrent of papers on the arXiv preprint server, topological insulators have become one of the hottest topics in physics—and not just in condensed-matter physics. Not only do these novel materials have potential applications in electronics, but they also harbor deep connections to particle physics. Nature‘s Geoff Brumfiel reports on the excitement surrounding this new field. For a more technical review, click on the cover image.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
