α-シヌクレインタンパク質の凝集体は多様な種類の細胞で形成され、さまざまな神経変性疾患の原因となることがある。構造コンホメーションがそれぞれ異なる凝集体群が複数存在することが、病態のこのような変動の原因なのかもしれない。

A review of western boundary currents in the Pacific Ocean explores their far-reaching influence on the El Niño/Southern Oscillation, the Indonesian Throughflow, Asian monsoons, and ocean circulation in the South China Sea, and concludes that major conceptual and technical progress will be needed to close the regional mass budget and provide robust projections of Pacific western boundary currents in a changing climate.

Spatial working memory is known to involve the prefrontal cortex and the hippocampus, but the specificities of the connection have been unclear; now, a direct path between these two areas is defined that is necessary for the encoding of spatial cues in mice, but is not required for the maintenance or retrieval of these cues.

The description of a compound (DDD107498) with antimalarial activity against multiple life-cycle stages of Plasmodium falciparum and good pharmacokinetic and safety properties, with potential for single-dose treatment, chemoprotection and prevention of transmission.

Observations are reported of a permanent, asymmetric dust cloud around the Moon, caused by impacts of high-speed cometary dust particles on eccentric orbits, as opposed to particles of asteroidal origin following near-circular paths striking the Moon at lower speeds.

Transition metal–ligand fragments are often able to bind and release several carbon monoxide molecules, such as the catalysts used in industrial-scale acetic acid synthesis and the active sites of hydrogenase enzymes, but main-group elements have never shown an ability to bind more than one carbon monoxide molecule; here a boron-based compound stable to moisture and air is synthesized and shown to contain multiple carbon monoxide units bound to the central boron atom.

A new dinosaur from the Late Jurassic period of Chile (about 150 million years ago) has been discovered and identified as a primitive kind of theropod that, unusually, was herbivore.

Acute re-activation of a positive memory engram suppresses depression-like behaviour in mice exposed to chronic stress, mediated by a hippocampus–amygdala–nucleus-accumbens pathway.

Brain α-synuclein deposits are the hallmark of various distinct neurodegenerative diseases, and it is proposed that α-synuclein assemblies with different structural characteristics or 'strains' (ribbons or fibrils) could account for pathological differences between these diseases; here different human α-synuclein strains are injected into rat brain, and are shown to propagate in a strain-dependent manner and cause different pathological and neurotoxic phenotypes.

Tumours maximize their chance of metastasizing by evoking a systemic inflammatory cascade in mouse models of spontaneous breast cancer metastasis.

Whether neutrophils exert an anti- or pro-tumorigenic function has remained controversial; now, expression of the receptor molecule MET in neutrophils is shown to be required for their ability to restrict tumour growth in several mouse cancer models, with potential implications for human cancer therapy.

The protein FAM134B is an endoplasmic reticulum (ER)-resident receptor that facilitates ER autophagy, and downregulation of this protein (mutations of which are also known to cause sensory neuropathy in humans) results in expanded ER structures and degeneration of mouse sensory neurons.

In yeast, the novel protein Atg40 is enriched in the cortical and cytoplasmic endoplasmic reticulum (ER), and loads these ER subdomains into autophagosomes to facilitate ER autophagy; Atg39 localizes to the perinuclear ER and induces autophagic sequestration of part of the nucleus, thus ensuring cell survival under nitrogen-deprived conditions.

Many human genes undergo alternative cleavage and polyadenylation to generate messenger RNA transcripts with different lengths at the 3' untranslated regions (3' UTRs) but that encode the same protein; now it is shown that these alternative 3' UTRs regulate protein localization.
