Redefining the invertebrate RNA virosphere p.539

Profiling the total RNA of 220 invertebrate species leads to the discovery of almost 1,500 new species of RNA virus, revealing that the RNA virosphere is much more diverse than was previously thought.

Persistent microbiome alterations modulate the rate of post-dieting weight regain p.544

The identification of an intestinal microbiome signature that persists after successful dieting in obese mice and contributes to faster weight regain upon re-exposure to an obesity-promoting diet, and that transmits the altered weight regain phenotype to non-dieting mice.

doi: 10.1038/nature20796


Early dissemination seeds metastasis in breast cancer p.552

Two related papers show that cells disseminated from malignant lesions at early time points during tumorigenesis can contribute to metastases at distant organs and provide insights into the molecular basis of dissemination.

doi: 10.1038/nature20785



Evidence for a spinon Fermi surface in a triangular-lattice quantum-spin-liquid candidate p.559

A spin excitation continuum across a large region of the Brillouin zone that persists at near-zero temperatures provides evidence for a quantum spin liquid state with a spinon Fermi surface in YbMgGaO4.

Self-assembly of tetravalent Goldberg polyhedra from 144 small components p.563

Graph theory is used to guide the self-assembly of a complex consisting of 48 palladium ions and 96 ligands, with the topology of a tetravalent Goldberg polyhedron.

doi: 10.1038/nature20771


Water balance creates a threshold in soil pH at the global scale p.567

There is an abrupt transition from alkaline to acid soil pH when mean annual precipitation exceeds mean annual potential evapotranspiration, demonstrating that climate creates a nonlinear pattern in soil solution chemistry at the global scale.

Broadening not strengthening of the Agulhas Current since the early 1990s p.570

The Agulhas Current has not intensified since the early 1990s, but has instead broadened as a result of more eddy activity.

Chemical intervention in plant sugar signalling increases yield and resilience p.574

Treatment with signalling precursors of trehalose-6-phosphate allows light-triggered release of trehalose-6-phosphate in Arabidopsis thaliana and increases the yield and drought resistance of spring wheat (Triticum aestivum).

Integrin-YAP/TAZ-JNK cascade mediates atheroprotective effect of unidirectional shear flow p.579

YAP and TAZ, effectors of the Hippo pathway, sense mechanical forces generated by blood flow and play a role in atherosclerosis pathogenesis.

NLRC3 is an inhibitory sensor of PI3K–mTOR pathways in cancer p.583

Mice deficient in the protein NLRC3 are highly prone to colitis and tumour development in the colon as NLRC3 suppresses the activation of mTOR signalling pathways that help drive tumorigenesis.

Mechanism of early dissemination and metastasis in Her2+ mammary cancer p.588

Two related papers show that cells disseminated from malignant lesions at early time points during tumorigenesis can contribute to metastases at distant organs and provide insights into the molecular basis of dissemination.

mRNA quality control is bypassed for immediate export of stress-responsive transcripts p.593

Heat shock drives the expression of transcripts that bypass mRNA quality control for direct export and translation, allowing cells to survive extreme situations at the cost of accuracy.

Structure of RNA polymerase I transcribing ribosomal DNA genes p.607

Structures of budding yeast RNA polymerase I in a catalytically active conformation are presented and confirmed by visualizing processive transcription along ribosomal DNA genes; they support a general model for transcription elongation in which contracted and expanded polymerase conformations are associated with active and inactive states, respectively.
