Feedback in low-mass galaxies in the early Universe p.169

Feedback in the form of galactic-scale outflows of gas from star-forming, low-mass galaxies allowed ionizing radiation to escape from galaxies when the Universe was about 500 million years old, changing the hydrogen between galaxies from neutral to ionized.

Glypican-1 identifies cancer exosomes and detects early pancreatic cancer p.177

Glypican-1 identifies cancer exosomes and serves as a biomarker for detection of early pancreatic cancer in patients and mouse models of the disease; the findings may enable early and non-invasive identification, and prevention of malignant cancer.

がん:レナリドマイドはdel(5q) MDSにおいてCK1αのユビキチン化と分解を引き起こす

Lenalidomide induces ubiquitination and degradation of CK1α in del(5q) MDS p.183

Lenalidomide, a derivative of thalidomide, is an effective drug for myelodysplastic syndrome; lenalidomide binds the CRL4CRBN E3 ubiquitin ligase and promotes degradation of casein kinase 1a, on which the malignant cells rely for survival.

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

A new class of ultra-long-duration γ-ray bursts (GRBs) has recently been suggested, with durations in excess of 10,000 seconds, and now a supernova (SN 2011kl) has been found to be associated with the ultra-long-duration GRB 111209A, allowing a physical understanding of the nature of ultra-long-duration GRBs.

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.

Long-range energy transport in single supramolecular nanofibres at room temperature p.196

Coherent energy transport is key to the operation of the photosynthetic machinery and the successful implementation of molecular electronics; self-assembled supramolecular nanofibres based on carbonyl-bridged triarylamines are now shown to transport singlet excitons over micrometre-scale distances at room temperature.

Basin-scale transport of hydrothermal dissolved metals across the South Pacific Ocean p.200

Hydrothermal dissolved iron, manganese, and aluminium from the southern East Pacific Rise is transported several thousand kilometres westward across the South Pacific Ocean; global hydrothermal dissolved iron input is estimated to be more than four times what was previously thought and modelling suggests it must be physically or chemically stabilized in solution.

Eye-like ocelloids are built from different endosymbiotically acquired components p.204

Dinoflagellate eye-like ocelloids are built from pre-existing organelles of disparate origin, including a cornea-like layer made of mitochondria and a retinal body made of anastomosing plastids.

Unusual biology across a group comprising more than 15% of domain Bacteria p.208

More than 15% of the bacterial domain consists of a radiation of phyla about which very little is known; here, metagenomics is used to reconstruct 8 complete and 789 draft genomes from more than 35 of these phyla, revealing a shared evolutionary history, metabolic limitations, and unusual ribosome compositions.

Human body epigenome maps reveal noncanonical DNA methylation variation OPEN p.212

As part of the Epigenome Roadmap Project, genome-wide maps of DNA methylation and transcriptomes together with genomic DNA sequencing of 18 different primary human tissue types from 4 individuals are presented; analysis reveals widespread differential methylation of CG sites between tissues, and the presence of non-CG methylation in adult tissues.

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.

Hypoxia fate mapping identifies cycling cardiomyocytes in the adult heart p.226

Fate-mapping hypoxic cells in the mouse heart identifies a rare population of cycling cardiomyocytes, which show characteristics of neonatal cardiomyocytes, including smaller size and mononucleation, and contribute to new cardiomyocyte formation in the adult heart.

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

Only a subset of patients with melanoma responds to new immunotherapeutic therapies; here, β-catenin signalling is identified as an important pathway that confers resistance to this type of approach, with implications for future treatment strategies.

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.

Condensin-driven remodelling of X chromosome topology during dosage compensation p.240

Genome-wide chromosome conformation capture analysis in C. elegans reveals that the dosage compensation complex, a condensin complex, remodels the X chromosomes of hermaphrodites into a sex-specific topology distinct from autosomes while regulating gene expression chromosome-wide.
