While clusters in calcium orthophosphate nucleation have long been known, their speciation and mechanistic pathways to hydroxyapatite remain debated. Here the authors report a revision of ion association in the calcium phosphate system and explore the consequences thereof on the early stages of phase separation.

Inertial active matter can self-organize into coexisting phases that feature different temperatures, but experimental realizations are limited. Here, the authors report the coexistence of hot liquid and cold gas states in mixtures of overdamped active and inertial passive Brownian particles, giving a broader relevance.

Here, the authors dissect the fuzzy interaction between the prokaryote transcription factor HigA2 and its DNA target and show that specific, transient interactions drive specificity despite HigA2 remaining mostly disordered.

Key molecular features that drive protein liquid–liquid phase separation (LLPS) for biomolecular condensate have been reported. A spectrum of additional interactions that influence protein LLPS and material properties have now been characterized. These interactions extend beyond a limited set of residue types and can be modulated by environmental factors such as temperature and salt concentration.

Strong light-matter interactions in optical microcavities can be used to control molecular kinetic and thermodynamic phenomena. Here, the authors introduce a theory that describes the nonperturbative effects of infrared microcavities on chemical equilibria.

With the increase of the use of quantum information in everyday life, its dynamics requires deeper understanding. Here, the quantum fluctuation theorem, that accounts for a quantum system interacting with the environment, is established within the framework of quasi-probability, a powerful tool for studying quantum statistics.

Ribonucleoprotein granules are ubiquitous in living organisms with the protein and RNA components having distinct roles. In the absence of proteins, RNAs are shown to undergo phase separation upon heating. This transition is driven by desolvation entropy and ion-mediated crosslinking and is tuned by the chemical specificity of the RNA nucleobases.

The electrochemical conversion of carbon dioxide to high-value multicarbon products is very desirable, but also fraught with immense complexity in process design. A twist in tuning product yields in this reaction could be based on water activity.

Sorption working pairs, which can convert low-grade heat into cold energy or seasonally store thermal energy, are potential future carbon-neutral materials for thermal management. This Comment highlights the superiorities of metal–organic framework (MOF)–ammonia working pairs for adaptable thermal management under extreme climates and discusses strategies to design MOFs with high stability and ammonia sorption capacity.

A paper in Nature Physics reports on freezing droplets that expel themselves from a textured surface.

An article in Advanced Materials reports an entropy tuning strategy to design sodium-ion battery electrolytes that adapt to low temperatures, enabling rechargeable batteries that work in the extreme cold.

A real qubit is not an isolated unitary quantum system but is subject to noise from its environment. An experiment has now turned this interaction on its head, controlling the environment using the qubit itself.
