A collection of papers catalogues the associations between genetic variation and gene expression in healthy tissues – the largest analysis of this kind so far. See Article p.204 & Letters p.239, p.244 & p.249
Pariahs are fundamental building blocks in a branch of mathematics called group theory, but seem to be unconnected from both physics and other areas of mathematics. Such a connection has now been identified.
Cancer cells can develop an 'addiction' to the drugs they are treated with, so that they need the drugs to survive. Analysis of the underlying mechanism reveals a potential clinical strategy for harnessing this phenomenon. See Letter p.270
Although liquid metals are effective fluids for heat transfer, pumping them at high temperatures is limited by their corrosiveness to solid metals. A clever pump design addresses this challenge using only ceramics. See Article p.199
The discovery of the receptors for the protein GDF15 suggests that it regulates food uptake through the emergency pathway — a neuronal circuit that causes weight loss in response to cancer, tissue damage and stress. See Letter p.255

Light-field-driven control of electrons in a conductor is demonstrated by inducing a current by laser pulses in graphene that is sensitive to the carrier-envelope phase.
High-performance semiconductor films with vertical compositions that are designed to
atomic-scale precision provide the foundation for modern integrated circuitry and
novel materials discovery. One approach to realizing such
films is sequential layer-by-layer assembly, whereby atomically thin two-dimensional
building blocks are vertically stacked, and held together by van der Waals
interactions. With this approach, graphene and
transition-metal dichalcogenides—which represent one- and three-atom-thick
two-dimensional building blocks, respectively—have been used to realize
previously inaccessible heterostructures with interesting physical properties. However, no large-scale assembly method exists at
present that maintains the intrinsic properties of these two-dimensional building
blocks while producing pristine interlayer interfaces,
thus limiting the layer-by-layer assembly method to small-scale proof-of-concept
demonstrations. Here we report the generation of wafer-scale semiconductor films
with a very high level of spatial uniformity and pristine interfaces. The vertical
composition and properties of these films are designed at the atomic scale using
layer-by-layer assembly of two-dimensional building blocks under vacuum. We
fabricate several large-scale, high-quality heterostructure films and devices,
including superlattice films with vertical compositions designed layer-by-layer,
batch-fabricated tunnel device arrays with resistances that can be tuned over four
orders of magnitude, band-engineered heterostructure tunnel diodes, and
millimetre-scale ultrathin membranes and windows. The stacked films are detachable,
suspendable and compatible with water or plastic surfaces, which will enable their
integration with advanced optical and mechanical systems.

Multiple transcriptome approaches, including single-cell sequencing, demonstrate that escape from X chromosome inactivation is widespread and occasionally variable between cells, chromosomes, and tissues, resulting in sex-biased expression of at least 60 genes and potentially contributing to sex-specific differences in health and disease.
Using the GTEx data and others, a comprehensive analysis of adenosine-to-inosine RNA editing in mammals is presented; targets of the various ADAR enzymes are identified, as are several potential regulators of editing, such as AIMP2.
GDNF receptor alpha-like is a brainstem-restricted receptor for growth and differentiation factor 15, regulating appetite and body weight in non-homeostatic conditions by activating the emergency circuit response to disease and toxin stresses.
