Electron capture in ¹⁶³Ho can be used to determine the electron neutrino mass. The Q value of this process is crucial for the evaluation of the systematic uncertainty in such a measurement, and a 50-fold improvement is now reported.

As amorphous solids, glasses and gels are similar, but the origins of their different elastic properties are unclear. Simulations now suggest differing free-energy-minimizing pathways: structural ordering for glasses and interface reduction for gels.

Controlling phase transitions in solids is crucial for many applications. Ultrafast laser pulses have now been shown to enable the energy-efficient generation of structural fluctuations in VO₂ by harnessing the correlated disorder in the material.

Linear topological systems can be characterized using invariants such as the Chern number. This concept can be extended to the nonlinear regime, giving rise to nonlinearity-induced topological phase transitions.

The Majorana Demonstrator experiment reports searches for the violation of the Pauli exclusion principle and of charge conservation. In the absence of a signal, exclusion limits for these processes are reported.

Quantum systems exhibit vastly different properties depending on their dimensionality. An experimental study with ultracold bosons now tracks quantum correlation properties during the crossover from two dimensions to one dimension.

Bart Verberck uses the musical cent as a pretext to touch on some of the intricacies of musical tuning systems.

Eighty years on from the publication of Erwin Schrödinger’s interdisciplinary analysis on the origin of order in living organisms — What is Life? — we look at how physicists and biologists are approaching the topic today.

The time has come to consider appropriate guardrails to ensure quantum technology benefits humanity and the planet. With quantum development still in flux, the science community shares a responsibility in defining principles and practices.

Measuring air temperature is far from a trivial task, as Andrea Merlone, Graziano Coppa and Chiara Musacchio explain.
