Recent theoretical work suggested that magic-angle graphene can simultaneously host localized and itinerant electrons. Now thermoelectric measurements provide evidence of this.

Solid-state quantum devices can suffer from decoherence caused by fluctuating electron spins in the surrounding material. Operating in a regime where the electron spins become magnetically ordered produces substantially longer coherence times.

The connection between classical neural networks and Gaussian processes is a fundamental result in machine learning. It has now been shown that many quantum neural networks converge to Gaussian processes, enabling their use for regression tasks.

Optical excitation is a way to control phase transitions in materials, but it lacks spatial specificity. Now, valley-selective photodoping in a Peierls insulator is demonstrated as a method to optically engineer phase textures with minimal heating.

The nonlinear mechanical properties of soft biological tissues and composites are poorly understood. Their strain stiffening under compression and shear is now found to be universal, and follows from the physics of the underlying biopolymer matrix.

Moiré patterns and flat bands usually occur in multilayer materials with a small interlayer twist angle, but this can cause detrimental lattice reconstruction. Now, flat bands are shown in a bilayer with large twist angle and structural rigidity.

Measurements play a crucial role in our daily lives; and we rely on metrology to ensure that measurements are accurate and comparable. Celebrating the 150th anniversary of the beginning of the global measurement system, we look into its future.

This month, we celebrate the 150-year anniversary of the signing of the Metre Convention and look to the future of metrology.

Many young metrologists have fascinating ideas that could shape the future of metrology. Chingis Kuanbayev and Kangyoung Sung tell us how the young professionals imagine what the field will look like beyond 2050.

Heliophysics focuses on understanding the different processes in the solar system and the influence of the Sun on space and planets. Collaboration between subfields of heliophysics and different communities needs to improve to advance the field.
