渡り鳥は全球的に減少しつつある。ヨーロッパの渡り鳥についての広範囲にわたる研究で、非繁殖期に広く分散する種は、分散範囲がもっと制限されている種に比べて数が減りにくいらしいことが分かった。

ハロゲン化アルケニルは、小型有機分子の合成に使われる最も有用な構成要素の一種である。容易に手に入るアルケンから交差メタセシス反応によって直接ハロゲン化アルケニルを作り出すことを可能にする触媒が見つかった。

宿主の微生物の個体数が多い海洋環境内では、宿主当たりのウイルス数が、宿主の個体数が少ない場合に比べて減少していることが分かった。これは、宿主と共存する溶原感染と宿主を殺す溶菌感染というウイルスの生き残り戦略の相対的な役割に関する理論に疑問を投じるものだ。

月の正反対の側に位置する2つの場所に存在する氷は、かつては月の向きが現在の自転軸からずれていたことを示唆している。この知見は、月の火山活動歴と関わりがある。

One shortcoming of olefin metathesis has been that acyclic alkenyl halides could not be generated efficiently and stereoselectively; but now halo-substituted molybdenum alkylidene species are shown to be able to participate in high-yielding olefin metathesis reactions that afford acyclic 1,2-disubstituted Z-alkenyl halides.

An analysis of 24 coral reef viromes challenges the view that lytic phage are believed to predominate when the density of their hosts increase and shows instead that lysogeny is more important at high host densities; the authors also show that this model is consistent with predator–prey dynamics in a range of other ecosystems, such as animal-associated, sediment and soil systems.

The loss of the TP53 gene is often involved in the development of human cancer; here, the deletion of other genes in the vicinity is shown also to contribute to cancer progression in a mouse model.

Deep γ-ray observations of the Galactic Centre with arcminute angular resolution show traces of petaelectronvolt protons within the central ten parsecs of our Galaxy; the accelerator of these particles could have provided a substantial contribution to Galactic cosmic rays in the past.

Polar hydrogen deposits on the Moon provide evidence that its spin axis has shifted; analysis of the locations of these deposits and of the lunar figure suggests that the shift occurred as a result of changes in the Moon’s moments of inertia caused by a low-density thermal anomaly beneath the Procellarum region.

Incomplete premelting at the edges of monolayer colloidal crystals is triggered by a bulk solid–solid phase transition and truncated by a mechanical instability that induces homogeneous bulk melting of the crystal; these observations challenge existing theories of two-dimensional melting.

Synthesis of atomically precise zigzag edges in graphene nanoribbons is demonstrated using a bottom-up strategy based on surface-assisted arrangement and reaction of precursor monomers; these nanoribbons have edge-localized states with large energy splittings.

Variability in North African dust dispersal, which affects air quality and the amount of radiation reaching the ground, is captured by the wind patterns over the Sahara; climate models suggest a downward trend in dust concentration with increasing greenhouse gas emissions.

To test whether there is a relationship between the level of national corruption and the intrinsic honesty of individuals, a behavioural test of the honesty of people from 23 countries was conducted; the authors found that high national scores on an index of rule-breaking are linked with reduced personal honesty.

The genus Homo had considerably smaller cheek teeth, chewing muscles and jaws than earlier hominins; here, the introduction of raw but processed meat, from which energy could more easily be extracted, is shown to have possibly been responsible for this change.

Nuclear DNA sequences from Middle Pleistocene Sima de los Huesos hominins show they were more closely related to Neanderthals than to Denisovans, and indicate a population divergence between Neanderthals and Denisovans that predates 430,000 years ago.

Experiments in transgenic mouse models of early Alzheimer’s disease show that the amnesia seen at this stage of the disease is probably caused by a problem with memory retrieval from the hippocampus rather than an encoding defect.

Tracing the fate of circulating tumour cells by intravital two-photon lung imaging shows that tumours produce microparticles as they arrive and these migrate along the lung vasculature and are mostly taken up by interstitial myeloid cells, in a process that contributes to metastatic seeding; a minor subset of microparticles is engulfed by conventional dendritic cells, which are thought to contribute to the initiation of an anti-tumour immune response in lung-draining lymph nodes.

A known oncogene, MITF, resides in a region of chromosome 3 that is amplified in melanomas and associated with poor prognosis; now, a long non-coding RNA gene, SAMMSON, is shown to also lie in this region, to also act as a melanoma-specific survival oncogene, and to be a promising therapeutic target for anti-melanoma therapy.

PGC1α protects against kidney injury by upregulating enzymes that enhance nicotinamide adenine dinucleotide (NAD) and driving local accumulation of the fatty acid breakdown product β-hydroxybutyrate, which leads to increased production of the renoprotective prostaglandin E2.
