This issue highlights the design of localizable implantable magnetic microdevices, and also includes advances in cancer-cell detection via lasing, in tumour therapy with a non-toxic dendrimer, and in the amplification of rare DNA-sequence variants.
The cover illustrates the concept of implantable microdevices that broadcast their location when in a magnetic-field gradient by emitting a magnetic-field-dependent radiofrequency signal (Article).

Causing nanoscale vibrations in bone-marrow stromal cells embedded in a soft collagen gel induces the cells to undergo osteogenic differentiation and mineralization via mechanosensitive signalling pathways.
