地球の表面プレートの下にある柔らかいマントル層中で水とメルトが果たす役割については議論が続いている。新たに得られたデータは、マントル層の最上部に少量のメルトが生じているというモデルを裏付けている。

若い太陽系外惑星の分光観測から、その自転速度が直接測定できた。得られた速い自転速度は、自転速度が惑星質量の関数として増加するという既知の傾向を外挿したものと一致している。

A population of spinal interneurons that form axo–axonic connections with the terminals of proprioceptive afferents are shown to mediate presynaptic inhibition; their ablation elicits harmonic oscillations during goal-directed forelimb movements, which can be modelled as the consequence of an increase in sensory feedback gain.

Haematopoietic stem cells (HSCs) have a lower rate of protein synthesis in vivo than most other haematopoietic cells, and both increases and decreases in the rate of protein synthesis impair HSC function, demonstrating that HSC maintenance—and hence, cellular homeostasis—requires the rate of protein synthesis to be highly regulated.

A longitudinal study of an individual patient developing neutralizing antibodies against HIV-1 (targeting the V1V2 region of gp120) reveals how such neutralizing antibodies develop and evolve over time, providing important insights relevant to vaccine development.

Near-infrared spectroscopic observations of the young extrasolar planet β Pictoris b indicate that it spins significantly faster than any planet in the Solar System, in line with the extrapolation of the known trend in spin velocity with planet mass.

Single organic dye molecules have high-flux, narrow-bandwidth single-photon emission and can be spectrally matched to the transitions of atoms acting as a quantum memory, making them promising for use in quantum information and communication schemes.

An enantioselective reaction involving a molecule with two axes of stereochemical consequence produces four stereoisomers, and rather than racemizing as the system approaches equilibrium, one of the diastereomeric pairs drifts spontaneously to a higher enantiomeric ratio.

New sea surface temperature and oxygen isotope records, combined with climate modelling experiments, show that slowdowns of the Atlantic meridional overturning circulation during Heinrich stadials and the Younger Dryas stadial affected the tropical Indian Ocean hydroclimate through changes to the Hadley circulation.

Determination of the electrical conductivity of carbon-dioxide- and water-rich melts, which are typically produced at the onset of mantle melting, shows that incipient melts can trigger the high electrical conductivities found in oceanic regions of the asthenosphere.

The long-term drying trend in central African rainforests might help to explain satellite-detected large-scale vegetation browning in the Congolese forests.

Using whole-genome and whole-exome sequencing, this study identifies eight significantly mutated genes in oesophageal squamous cell cancer, including two genes, ADAM29 and FAM135B, not previously associated with this cancer type.

Cystathionine γ-lyase, which is responsible for the production of cysteine, is decreased in the striatum and cortex of mouse models of Huntington’s disease and in patients with Huntington’s disease, and cysteine supplementation in diet and drinking water partly rescues the phenotype and the diminished longevity of the mouse model.

Reprogramming after somatic cell nuclear transfer had been thought to be dependent on the recipient cytoplasm being arrested at the metaphase stage, but here interphase two-cell mouse embryos are shown to support successful reprogramming and generation of embryonic stem cells or cloned mice.

Through a quantitative proteomics analysis, a cohort of proteins is identified that associate with autophagosomes, among them a new cargo receptor called NCOA4 that, in response to iron deprivation, targets ferritin to autophagosomes and thereby releases iron.

RIG-I protein recognizes viral duplex RNA with a 5′-triphosphate group, activating innate immune responses; a crystal structure of its tetrameric CARD signalling domain reveals that non-covalently linked ubiquitin chains stabilize the tetramer in a ‘lock-washer’ structure that serves as a signalling platform for the recruitment and activation of MAVS.

The X-ray crystal structure of the human P2Y12 receptor, which regulates platelet activation and thrombus formation, is solved in complex with an antithrombotic drug, providing insights for the development of new drugs.
