  • In studies in mammalian cells, polymerase theta (Polθ, also known as POLQ) is identified as the polymerase responsible for non-homologous end joining DNA repair; this DNA repair pathway acts in many tumours when homologous recombination is inactivated and the identification of the polymerase responsible may aid the development of new therapeutic approaches.

  • Using pump-power-dependent exciton absorption spectroscopy, the authors reveal magnon-mediated exciton–exciton interactions and a consequent nonlinear optical response in CrSBr, an antiferromagnetic semiconductor.

  • The Cancer Genome Atlas Research Network reports an integrative analysis of more than 400 samples of clear cell renal cell carcinoma based on genomic, DNA methylation, RNA and proteomic characterisation; frequent mutations were identified in the PI(3)K/AKT pathway, suggesting this pathway might be a potential therapeutic target, among the findings is also a demonstration of metabolic remodelling which correlates with tumour stage and severity.

  • Understanding the process of exciton fission, which occurs in certain organic materials, could lead to the development of more efficient photovoltaic devices. Here, an expression derived from first principles is used to accurately characterize the singlet fission rate of a wide array of materials, reproducing a transition from weak to strong coupling as a function of molecular separation.

  • The Cancer Genome Atlas consortium reports on their genome-wide characterization of somatic alterations in colorectal cancer; in addition to revealing a remarkably consistent pattern of genomic alteration, with 24 genes being significantly mutated, the study identifies new targets for therapeutic intervention and suggests an important role for MYC-directed transcriptional activation and repression.

  • Comprehensive analyses of 178 lung squamous cell carcinomas by The Cancer Genome Atlas project show that the tumour type is characterized by complex genomic alterations, with statistically recurrent mutations in 11 genes, including TP53 in nearly all samples; a potential therapeutic target is identified in most of the samples studied.

  • The Cancer Genome Atlas Network describe their multifaceted analyses of primary breast cancers, shedding light on breast cancer heterogeneity; although only three genes (TP53, PIK3CA and GATA3) are mutated at a frequency greater than 10% across all breast cancers, numerous subtype-associated and novel mutations were identified.

  • With a comprehensive analysis of sequencing data, DNA copy number, gene expression and DNA methylation in a large number of human glioblastomas, The Cancer Genome Atlas project initiative provides a broad overview of the genes and pathways that are altered in this cancer type.
