A very luminous magnetar-powered supernova associated with an ultra-long γ-ray burst p.189

A new class of ultra-long-duration (more than 10,000 seconds) γ-ray bursts has recently been suggested. They may originate in the explosion of stars with much larger radii than those producing normal long-duration γ-ray bursts or in the tidal disruption of a star. No clear supernova has yet been associated with an ultra-long-duration γ-ray burst. Here we report that a supernova (SN 2011kl) was associated with the ultra-long-duration γ-ray burst GRB 111209A, at a redshift z of 0.677. This supernova is more than three times more luminous than type Ic supernovae associated with long-duration γ-ray bursts, and its spectrum is distinctly different. The slope of the continuum resembles those of super-luminous supernovae, but extends further down into the rest-frame ultraviolet implying a low metal content. The light curve evolves much more rapidly than those of super-luminous supernovae. This combination of high luminosity and low metal-line opacity cannot be reconciled with typical type Ic supernovae, but can be reproduced by a model where extra energy is injected by a strongly magnetized neutron star (a magnetar), which has also been proposed as the explanation for super-luminous supernovae.

Global-scale coherence modulation of radiation-belt electron loss from plasmaspheric hiss p.193

Simultaneous measurements of structured radiation-belt electron losses (in the form of bremsstrahlung X-rays) and plasmaspheric hiss (which causes the losses) reveal that the loss dynamics is coherent with the hiss dynamics on spatial scales comparable to the size of the plasmasphere.

Global circulation patterns of seasonal influenza viruses vary with antigenic drift p.217

The analysis of more than 9,000 haemagglutinin sequences of human seasonal influenza viruses over a 12-year time period shows that the global circulation patterns of A/H1N1 and B viruses are different from those of the well characterised A/H3N2 viruses; in particular the A/H1N1 and B viruses are shown to persist locally across several seasons and do not display the same degree of global movement as the H3N2 viruses.

Th17 cells transdifferentiate into regulatory T cells during resolution of inflammation p.221

Analysis of a mouse model shows that during the course of an immune response, helper T cells undergo functional reprogramming to transdifferentiate into regulatory T cells; this T cell plasticity could possibly be exploited to develop better therapies for restoring immune tolerance in autoimmune diseases.

Melanoma-intrinsic β-catenin signalling prevents anti-tumour immunity p.231

Melanoma treatment is being revolutionized by the development of effective immunotherapeutic approaches. These strategies include blockade of immune-inhibitory receptors on activated T cells; for example, using monoclonal antibodies against CTLA-4, PD-1, and PD-L1 (refs 3, 4, 5). However, only a subset of patients responds to these treatments, and data suggest that therapeutic benefit is preferentially achieved in patients with a pre-existing T-cell response against their tumour, as evidenced by a baseline CD8+ T-cell infiltration within the tumour microenvironment. Understanding the molecular mechanisms that underlie the presence or absence of a spontaneous anti-tumour T-cell response in subsets of cases, therefore, should enable the development of therapeutic solutions for patients lacking a T-cell infiltrate. Here we identify a melanoma-cell-intrinsic oncogenic pathway that contributes to a lack of T-cell infiltration in melanoma. Molecular analysis of human metastatic melanoma samples revealed a correlation between activation of the WNT/β-catenin signalling pathway and absence of a T-cell gene expression signature. Using autochthonous mouse melanoma models we identified the mechanism by which tumour-intrinsic active β-catenin signalling results in T-cell exclusion and resistance to anti-PD-L1/anti-CTLA-4 monoclonal antibody therapy. Specific oncogenic signals, therefore, can mediate cancer immune evasion and resistance to immunotherapies, pointing to new candidate targets for immune potentiation.

Cyclic di-GMP acts as a cell cycle oscillator to drive chromosome replication p.236

In Caulobacter crescentus, oscillating levels of the second messenger cyclic-di-GMP drive the cell cycle through regulation of the essential cell cycle kinase CckA; as its levels increase during the G1–S transition, cyclic-di-GMP binds to CckA to inhibit kinase and stimulate phosphatase activity, thereby enabling replication initiation.
