Superionic water found at the core of giant planets has been studied in the laboratory, where extreme geological conditions of temperature (several thousand degrees) and pressure (several million times atmospheric pressure) have been reproduced on very small systems.

Unexpected structural complexity at the heart of superionic water

Elastic model of an icosahedral viral capsid. The capsid consists of triangular subunits, some of which are marked here in orange, which can be deformed to minimise the energy of the whole. The colours of the proteins are chosen to reflect their symmetry group.

Flexible proteins for assembling viruses: from disorder to symmetry

The input numbers are first transformed into a one-dimensional vector, which is then encoded into a pumping pattern by matrix multiplication.

Where’s the bias, then?

Ultra-fine grain aluminum observed under transmission electron microscopy showing a crack propagating in an area where all crystal domains with different orientations (the “grains”) are identified by color. As they move, the interfaces between these domains (the “grain boundaries”) carry a small deformation that can blunt the crack.

Three dynamic regimes for learning in a two-layer neural network with m hidden neurons (labeled MF, Feat. learning, Feat. learning and Overfit/Unlearn in the figure).
