Chemistry at the boundary between phases: adsorption, wetting, thin films, and the interfaces where most catalysis actually happens.

Treatment by operation: the techniques, the decisions about when to operate, and the outcomes that follow.

How words combine into phrases and clauses, and what makes one string of them grammatical and another not.

Designing and building biological parts and circuits that do not exist in nature, and redesigning the ones that do.

Music approached through the sciences: acoustics and psychoacoustics, music cognition, and the empirical study of what listeners actually hear.

Naming organisms and working out how they are related: classification, nomenclature, and the evolutionary trees that justify both.

The doctrines of a tradition worked into a coherent whole, and the arguments about where they contradict each other.

Treating a cell or an organism as a network rather than a parts list: modelling how genes, proteins and metabolites interact to produce behaviour the individual components do not have.

Engineering a system as a whole rather than its parts: requirements, interfaces, verification, and the failures that only appear at the seams.

The study of systems as systems -- feedback, control, self-regulation -- across the mathematical, computational and engineering traditions that share the idea.

The rules that decide who owes what to the treasury, and the doctrine that grows up around avoidance, evasion and cross-border income.

Research on how teachers are prepared and how they keep developing: what training changes, what it does not, and how a novice becomes fluent in a classroom.

The large-scale motion and deformation of the Earth's crust: plate boundaries, mountain building, rifting, and the forces behind them.

Carrying information over distance: modulation, coding, antennas, optical links and the networks assembled from them.

Reconstructing what an author wrote from copies that disagree: collation, stemmatics, and the editorial judgment a critical edition rests on.

Drama and its staging: text and performance, theatre history, and the conventions an audience has to know for any of it to land.

Reasoned inquiry into the claims of a religious tradition, conducted from within it. Distinct from religious studies, which examines those claims from outside.

Chemistry done with mathematics and physical models rather than reagents: bonding theory, molecular structure, and the prediction of what a reaction will do.

The study of what can be computed and how efficiently, including automata, complexity, and computability.

Heat put to work: engines, turbines, refrigeration, heat exchangers, and the efficiency limits thermodynamics imposes on all of them.
