Analysis of cancer genome sequencing data has enabled the discovery of driver mutations. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium the authors present DriverPower, a software package that identifies coding and non-coding driver mutations within cancer whole genomes via consideration of mutational burden and functional impact evidence.

Understanding deregulation of biological pathways in cancer can provide insight into disease etiology and potential therapies. Here, as part of the PanCancer Analysis of Whole Genomes (PCAWG) consortium, the authors present pathway and network analysis of 2583 whole cancer genomes from 27 tumour types.

The authors present SVclone, a computational method for inferring the cancer cell fraction of structural variants from whole-genome sequencing data.

Here, the authors develop ActivePathways method, which uses data fusion techniques for integrative pathway analysis of multi-omics data and candidate gene discovery.

Arrays of quantum dots can exhibit a variety of quantum properties, being sensitive to their spacing. Here, the authors fine tune interdot coupling using hexagonal molecular networks in which the dots are separated by single or double haloaromatic compounds, structurally identical but for a single atom.

In this study, the authors show that autophagy controls blood cell differentiation in a Drosophila model of hematopoiesis. Notch activation depends on the endocytic pathway and promotes crystal cell differentiation, while autophagy reduces Notch accumulation via lysosomal destruction in a nutrient-dependent manner.

Signaling between endothelial and blood cell types controls inflammatory and thrombotic responses. Andrés Hidalgo and his coworkers now uncover a signaling mechanism by which the endothelium, acting on adherent leukocytes, promotes the capture of platelets or red blood cells by those leukocytes, contributing to pathology in mouse models of two very different types of disease—transfusion-related acute lung injury and sickle cell disease(pages 364–366).

The design of open-shell nanographenes is commonly limited to systems featuring a single magnetic origin. Now a strategy that combines topological frustration and electron–electron interactions has been developed to generate a butterfly-shaped nanographene that hosts four highly entangled π-spins and exhibits both ferromagnetic and anti-ferromagnetic coupling.
