What sparked the Cambrian explosion? p.268

An evolutionary burst 540 million years ago filled the seas with an astonishing diversity of animals. The trigger behind that revolution is finally coming into focus.

Photons paired with phonons p.284

The force exerted by light on an object has been used to pair photons with quantum units of mechanical vibration. This paves the way for mechanical oscillators to act as interfaces between photons and other quantum systems. See Letter p.313

Hand of the gods in human civilization p.285

Cross-cultural experiments find that belief in moralistic, knowledgeable and punishing gods promotes cooperation with strangers, supporting a role for religion in the expansion of human societies. See Letter p.327

Ice streams waned as ice sheets shrank p.287

It emerges that ice discharge from a major ice sheet did not increase rapidly at the end of the most recent ice age. The finding points to steady, not catastrophic, ice-sheet loss and sea-level rise on millennial timescales. See Letter p.322

Form follows function for mitochondria p.288

The fission of organelles called mitochondria has now been linked to the stress-sensor protein AMPK. When activated by stress, this protein phosphorylates the mitochondrial receptor protein MFF, which recruits the fission machinery.

Females have a lot of guts p.289

The discovery of sex-biased proliferation in the intestinal stem cells of fruit-fly midguts reveals that the organ's size is determined by a previously undefined, sex-specific molecular pathway. See Letter p.344

From sea to sea p.290

The genome sequence of the marine flowering plant eelgrass (Zostera marina) sheds light on how marine algae evolved into land plants before moving back to the sea. See Letter p.331

The peptidergic control circuit for sighing p.293

The peptidergic neuronal circuit controlling sigh generation has been identified as ~200 Nmb- or Grp-expressing neurons in the RTN/pFRG breathing control centre of the medulla that project to ~200 receptor-expressing neurons in the respiratory rhythm generator, the preBötzinger Complex.

Cryo-EM structure of the yeast U4/U6.U5 tri-snRNP at 3.7 Å resolution p.298

A 3.7 Å resolution structure for the yeast U4/U6.U5 tri-snRNP, a complex involved in splicing, allows a better appreciation of the architecture of the tri-snRNP, and offers new functional insights into the activation of the spliceosome and the assembly of the catalytic core.

Super-catastrophic disruption of asteroids at small perihelion distances p.303

By comparing asteroid detections and a near-Earth-object model the deficit of objects near the Sun is shown to arise from the breakup of most asteroids, especially low-albedo ones, at distances of a few tens of solar radii from the Sun.

Universal resilience patterns in complex networks p.307

An analytical framework is proposed for a complex network to accurately predict its dynamic resilience and unveil the network characteristics that can enhance or diminish resilience.

Uranium-mediated electrocatalytic dihydrogen production from water p.317

Homogenous electrocatalytic water reduction with formation of dihydrogen is demonstrated with a trisaryloxide U(iii) complex, for which the catalytic cycle was elucidated and found to involve rare terminal U(iv)–OH and U(v)=O complexes.

Ice stream activity scaled to ice sheet volume during Laurentide Ice Sheet deglaciation p.322

Reconstruction of the activity of ice streams operating during the retreat of the Laurentide Ice Sheet reveals that the number of ice streams and their total discharge decreased as the total volume of the ice sheet decreased, suggesting that ice stream activity did not accelerate the collapse of the ice sheet.

Moralistic gods, supernatural punishment and the expansion of human sociality p.327

Using economic games, the authors examine the role of religion in the persistence of human cooperation; individuals who claim that their gods are moralizing, punitive and knowledgeable about human affairs are more likely to play fairly towards geographically distant co-religionists.

Effector T-cell trafficking between the leptomeninges and the cerebrospinal fluid p.349

By investigating trafficking of autoreactive T cells into the CSF during experimental autoimmune encephalitis, the authors find that T cells enter the CSF from the leptomeninges, and that commuting between the leptomeninges and the CSF is regulated by integrin adhesive forces triggered by T-cell activation and/or chemokines.
