Spin current on topological insulator detected electrically at room temperature
This image shows the schematics of the spin current on a topological insulator surface, with the spin direction (S) perpendicular to the current direction (kx). The zoom in schematic shows the electronic band structure on the surface of the topological insulator. The spin polarization on topological insulator surface is electrically probed by a ferromagnetic tunnel contact (FM).

Guided ultrasound plus nanoparticle chemotherapy cures tumors in mice
MRgFUS combines an ultrasound beam that heats and destroys tissue with a magnetic resonance imaging to guide the beam and monitor the effects of treatment. The effectiveness of the treatment can be limited by the need to spare normal tissue or critical structures on the tumor margins, as well as the need to eliminate micrometastases.
