Molecular frameworks featuring perovskite-related topologies rarely exhibit strong magnetic correlations and high-temperature magnetic order. Now it has been shown that the cubic molecular framework Cr(pyrazine)₃ exhibits persistent compensated ferrimagnetism with oxide-strength magnetic coupling and nearly zero net moment. The ferrimagnetism is sustained across a broad temperature range and extends well above room temperature.

Meta-analysis of genome-wide association studies on Alzheimer’s disease and related dementias identifies new loci and enables generation of a new genetic risk score associated with the risk of future Alzheimer’s disease and dementia.

The flagship paper of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes Consortium describes the generation of the integrative analyses of 2,658 cancer whole genomes and their matching normal tissues across 38 tumour types, the structures for international data sharing and standardized analyses, and the main scientific findings from across the consortium studies.

Known genetic loci account for only a fraction of the genetic contribution to Alzheimer’s disease. Here, the authors have performed a large genome-wide meta-analysis comprising 409,435 individuals to discover 6 new loci and demonstrate the efficacy of an Alzheimer’s disease polygenic risk score.

Brain age gaps (BAGs) highlight deviations from healthy brain aging, yet their biophysical underpinnings in aging and dementia are not well understood. Here, the authors use EEG connectivity and generative modeling across diverse populations to reveal that BAGs are influenced by geography, income, sex and education, with implications for understanding accelerated aging and dementia.

Analyses of neuroimaging datasets from 5,306 participants across 15 countries found generally larger brain-age gaps in Latin American compared with non-Latin American populations, which were influenced by disparities in socioeconomic and health-related factors.

Three-dimensional nanofabrication allows for the precise tailoring of curvature of magnetic nanowires, and therefore the local symmetry breaking. Here, Ruiz-Gomez et al use this control to study the interaction of domain walls with local curvature, engineering potential wells and shift registers.

Helicity of photons is exploited for preferential emission direction and sorting of valley-polarized excitons is achieved at room temperature.
