New device switches between two operating modes as it is extended and contracted and might also be deployed in space
New two-dimensional compound could be used to study interactions that produce unconventional superconductivity and related quantum phenomena
Findings could help improve cell efficiencies still further, say physicists
Discovery could aid the development of quantum computing architectures in which qubits are implanted randomly into a host matrix
Validation of Wiedemann–Franz law in cuprates has implications for electron transport in strongly correlated materials
Layered clays called ophiolites trap carbon efficiently and may still be cooling the planet today
