Particle physics: No sign of asymmetry in the strong force p.477

The strong force binds the constituents of nuclei together. Differences between the force's fundamental interactions and their mirror images were thought to have been observed in heavy-ion collisions, but new data challenge this picture.

Bacterial pathogens: A spoonful of sugar could be the medicine p.479

Pili are filamentous bacterial structures that promote adhesion to host cells. It emerges that a small molecule that inhibits this adhesion can prevent colonization of the mouse gut by a pathogenic bacterium. See Letter p.528

Neuroinflammation: Synapses pruned in lupus p.482

Lupus is an autoimmune disease that can cause brain dysfunction. Studies in mouse models of lupus find that interferon proteins can cause the brain's immune cells to trim the synaptic connections between neurons. See Letter p.539

Climate science: Clouds unfazed by haze p.483

The extent to which aerosols affect climate is highly uncertain. Observations of clouds interacting with aerosols from a volcanic eruption suggest that the effect is much smaller than was once feared. See Article p.485

Strong constraints on aerosol–cloud interactions from volcanic eruptions p.485

Investigations of an Icelandic volcanic eruption confirm that sulfate aerosols caused a discernible yet transient brightening effect, as predicted, but their effect on the liquid water path was unexpectedly negligible.

A retinal code for motion along the gravitational and body axes p.492

Global mapping shows that mouse retinal neurons prefer visual motion produced when the animal moves along two behaviourally relevant axes, allowing the encoding of the animal’s every translation and rotation.

Exosomes facilitate therapeutic targeting of oncogenic KRAS in pancreatic cancer p.498

Exosomes improve the delivery of siRNA to mutant KRAS in the pancreatic tumours and bypass immune clearance better than artificial liposomes, probably owing to enhanced macropinocytocis and presence of CD47 on exosomes, respectively.

A massive, dead disk galaxy in the early Universe p.510

When the Universe was just 3 billion years old, half of the most massive galaxies had already ceased star formation, and such a galaxy has now been observed using gravitational lensing, unexpectedly turning out to be a compact, fast-spinning disk galaxy rather than a proto-bulge galaxy.

PTEN counteracts FBXL2 to promote IP3R3- and Ca2+-mediated apoptosis limiting tumour growth p.554

PTEN, a known tumour suppressor, inhibits the FXBL2-dependent degradation of IP3R3, an IP3 receptor, thus augmenting IP3R3-mediated calcium release from the endoplasmic reticulum to mitochondria and inducing apoptosis; inhibiting FXBL2 sensitizes PTEN-deficient tumours to photodynamic therapy.
