A high-resolution gene expression atlas of prenatal and postnatal brain development of rhesus monkey charts global transcriptional dynamics in relation to brain maturation, while comparative analysis reveals human-specific gene trajectories; candidate risk genes associated with human neurodevelopmental disorders tend to be co-expressed in disease-specific patterns in the developing monkey neocortex.

Increased potential for branched-chain amino acid and lipopolysaccharide biosynthesis in the gut microbiome of insulin-resistant individuals suggests that changes in the serum metabolome induced by dysbiosis, and driven by only a handful of species, contribute to the development of diabetes.

Protection of nascent DNA from degradation provides a mechanism that can promote synthetic viability and drug resistance in Brca-deficient cells without restoring homologous recombination at double-strand breaks.

Observations of reverberation arising from gravitationally redshifted iron Kα photons reflected off the inner accretion flow in a tidal disruption event demonstrate that X-rays originate from a region very close to the central black hole and not from a relativistic jet, as previously thought.

The widespread rimmed grooves, lineations and elongate craters extending from the Imbrium impact basin on the Moon, termed the Imbrium Sculpture, includes a non-radial component that is used to infer that the Imbrium impactor was the size of a proto-planet—about half the diameter of Vesta.

Experimental demonstration of excitonic attraction between two electrons is achieved in quantum devices made from carbon nanotubes, where the interaction between two electrons is reversed from repulsive to attractive owing to their strong Coulomb interaction with another electronic system.

The incorporation of large numbers of chemically diverse functional components into microfabricated structures at precise locations is challenging; now the precision placement of DNA origami by directed self-assembly is shown to overcome this problem for the purpose of reliably and controllably coupling molecular emitters to photonic crystal cavities.

A co-catalyst system for electrochemical alcohol oxidation composed of a bipyridine copper catalyst and an electron-proton-transfer mediator called TEMPO operates at much lower potential and is faster than TEMPO alone.

Here it is shown that the late twentieth century warming trends in the Antarctic Peninsula have ceased, with the Peninsula having instead been cooling for most of the twenty-first century, underscoring the considerable internal variability within the Antarctic climate system.

Data from over 2,500 reefs worldwide is used to identify 15 bright spots—sites where reef biomass is significantly higher than expected—and surveys of local experts in these areas suggest that strong sociocultural institutions and high levels of local engagement are among the factors supporting higher fish biomass.

Mature pancreatic β-cells can be distinguished from proliferating ones by expression of the Fltp reporter gene, which is triggered by Wnt signalling and β-cell polarization and islet compaction.

RNA caps other than the 7-methylguanylate modification are generated by a distinct mechanism in which caps are added during, not after, transcription initiation through the use of non-canonical initiating nucleotides by RNA polymerases, a finding which has functional consequences.
