Chris Toumey explains why the actions on science policy taken so far by the current US administration are cause for concern.

One-dimensional microwave Bragg gratings make it possible to coherently control donor nuclear spins in silicon by purely electrical means.

The unique photoresponse of a porous silicon nanowire can be harnessed to make a highly efficient photon-gated transistor with an on–off ratio comparable to that of a conventional electronic switch.

A thermally activated micromechanical switch delivers an electrical readout signal only when irradiated by a narrowband mid-infrared light, thanks to a metamaterial element that converts light into heat.

The use of time-resolved X-ray microscopy allows a direct visualization of the magnetization switching for nanomagnets under the effect of spin–orbit torques.

Phase-coherent caloritronics is an emerging field of nanoscience based on the possibility to control and manipulate heat currents thanks to the long-range phase coherence of the superconducting condensate

The electric field generated by a gate electrode is exploited to trigger a reversible ferromagnetic–paramagnetic phase transition in a magnetic topological insulator close to a quantum critical point.

Coplanar photonic bandgap resonators are used to implement an all-electrical method for controlling neutral ³¹P and ⁷⁵As donor nuclear spins in silicon.

Porous silicon nanowires enable optical switching and electrical current amplification in a photon-triggered transistor.

Infrared light of specific wavelength triggers a passive microsystem capable of producing a digitized output bit.

Arrayed nanochannels can be used to controllably transfect and reprogram tissues in vivo for applications in regenerative medicine and cell-based therapies.

Time-resolved X-ray microscopy reveals the mechanism and speed of current-induced magnetization switching of Co/Pt dots under the combined effect of spin-orbit torques and Dzyaloshinskii–Moriya interaction.

A silicon nanobeam cavity laser integrated with monolayer molybdenum ditelluride enables room-temperature lasing in the near infrared.

Lithium alloy nanoparticles are encased inside few-layer graphene to yield a chemically stable, high-capacity anode with promising performance in a full-cell configuration.

Localized surface plasmon resonance can be used to control the energy flow in plasmonic core-shell Ag–Pt nanocubes and excite energetic charge carriers in the thin Pt shell, which can then drive CO oxidation.

A proof-of-principle study shows that electromagnetic field-based in vivo lineage conversion can be used as a therapeutic strategy for the treatment of neurodegenerative disorders.

Universities and institutions in the United States are getting ready to celebrate nanotechnology and its achievements for National Nanotechnology Day. Lisa Friedersdorf, Quinn Spadola and Brendan Ryan share students' plans for the occasion.
