Over one hundred loci have been identified to be associated with the familial risk of prostate cancer but the functional effects are poorly understood. Here the authors use single-nucleotide variant and epigentic data to show an underlying genetic architecture marked by histone modification.

The authors report on a temperate Earth-sized planet orbiting the cool M6 dwarf LP 791-18 with a radius of 1.03 ± 0.04 R_⊕ and an equilibrium temperature of 300–400 K, with the permanent night side plausibly allowing for water condensation.

Genome-wide analysis of copy number variants in 2,824 cases across the phenotypic spectrum of CAKUT sheds light on the genomic architecture of disease and identifies TBX6 as a driver for CAKUT subphenotypes in the 16p11.2 microdeletion syndrome.

Analysing a database of >200,000 feeding links between >5,000 species in terrestrial and aquatic food webs, the authors show that specific trait combinations can be used to predict which predator species are characterized by high body-mass ratio interactions with their prey.

The prediction of mortality due to prostate cancer remains challenging. Here, the authors perform trans-ancestry metaanalysis with a focus on binding sites of the androgen receptor and develop a polygenic risk score.

Christopher Haiman, Bogdan Pasaniuc, David Reich and colleagues report a major role for low-frequency variation in the risk for prostate cancer. They show that alleles with >1% minor allele frequency contribute an order of magnitude more to risk for prostate cancer than these alleles do to overall genetic variation.

Myriad extracellular and intracellular cues regulate stem cell fate choice. Here, Liu et al. report intracellular pH dynamics as a previously unrecognized regulator to selectively mediate the secretory cell fate decision of the intestinal stem cell.

Prey bacteria have evolved different strategies to counteract predation but the genetic basis remains unclear. Here, Duncan et al. identify key genes involved in Vibrio cholerae sensitivity to Bdellovibrio bacteriovorus predation, providing new insights into prey resistance mechanisms.

The use of a thermally activated DNA polymerase PCR gives improved specificity, sensitivity and product yield without additives or extra process steps.

GWAS have enhanced our understanding for the genetic basis of breast cancer, but the majority of them were performed for European ancestry populations. Here, the authors use a cross-ancestry approach and report seven new variants associated with breast cancer risk among women of African ancestry.

Breakdown of the blood–brain barrier in individuals carrying the ε4 allele of the APOE gene, but not the ε3 allele, increases with and predicts cognitive impairment and is independent of amyloid β or tau pathology.

A large meta-analysis combining genome-wide and custom high-density genotyping array data identifies 63 new susceptibility loci for prostate cancer, enhancing fine-mapping efforts and providing insights into the underlying biology.

Patients undergoing radiation treatment for Hodgkins's lymphoma are at increased risk of developing secondary malignancies with time. This genome-wide analysis identifies genetic polymorphisms associated with increased risk of secondary malignancies in treated children. The risk alleles result in decreased radiation-mediated induction of PRDM1, a tumor suppressor transcription factor, leading to impaired repression of oncogenic drivers such as MYC.

In colorectal cancer (CRC), finding loci associated with risk may give insight into disease aetiology. Here, the authors report a genome-wide association analysis in Europeans of 34,627 CRC cases and 71,379 controls, and find 31 new risk loci and 17 new risk SNPs at previously reported loci.

In this study, the authors develop a comprehensive taxonomy of brain-wide SPNs, identifying several novel subsets via their transcriptional signatures.

Centrioles have a conserved structure and function but have diversified in sperm. Here the authors provide insight into the molecular mechanisms and adaptive evolution underlying this diversification.

Age at voice-breaking is used to determine puberty timing in men, recall of which is considered less accurate than age at first menarche in women. Here, the authors perform multi-trait GWAS for male puberty timing by including both age at voice breaking and age of first facial hair for improved phenotype definition and power.

Genome wide association studies have identified multiple loci associated with risk of developing prostate cancer but the functional significance of many of these are unknown. Here, after generating models to predict methylation, the authors identify CpG methylation sites associated with prostate cancer.

The nonsense-mediated mRNA decay (NMD) pathway is triggered upon assembly of the UPF surveillance complex near an exon junction complex (EJC). Cryo-EM studies have revealed the geometry of this transient assembly between the UPF complex and the EJC, which demonstrates how the UPF1 subunit elicits its RNA helicase activity toward the 3A end of the mRNA.

Multiple myeloma is a cancer of the plasma cells, and the complete aetiology of the disease is still unclear. Here the authors perform an additional GWAS analysis followed by a meta-analysis with existing GWAS and replication genotyping and identify 6 novel risk loci and utilise gene expression, epigenetic profiling and in situ Hi-C data to further our understanding of MM susceptibility.

Richard Houlston and colleagues report a genome-wide association study for colorectal cancer. They report three loci newly associated with colorectal cancer, bringing the total number of common susceptibility loci to 20.

Normothermic machine perfusion of the liver improved early graft function, demonstrated by reduced peak serum aspartate transaminase levels and early allograft dysfunction rates, and improved organ utilization and preservation times, although no differences were seen in graft or patient survival.

Genome-wide association studies (GWAS) have identified hundreds of genomic risk regions for prostate cancer. Here, the authors perform a transcriptome wide association study (TWAS) by incorporating prostate cancer GWAS with gene expression data to identify potential novel prostate cancer risk loci and possible risk mechanisms.

Pathological compulsive behaviour is a potential transdiagnostic symptom of several neuropsychiatric disorders. In this Review, Robbins et al. examine the psychological basis of compulsions and compulsivity and their underlying neural circuitry, focused on fronto-striatal systems implicated in goal-directed behaviour and habits.

Wei Zheng and colleagues report genome-wide analyses in east Asians and identify three new loci associated with colorectal cancer risk.

Patients with advanced cancer often have no access to potentially effective targeted drugs, despite expressing a known biomarker of a marketed drug. However, if the agent is not licensed for that particular malignancy, the only solution is to prescribe the drug off-label or not at all. Tumour molecular profiling can exacerbate this dilemma. The authors of this Perspectives discuss the French AcSé Programme that aims to provide access to molecular testing and the option to receive targeted drugs outside of planned or approved marketing indications in a manner that is safe and further builds on the evidence-base for the use of such agents.

Quantum electrodynamics predicts a rare process in which light is scattered by light. The ATLAS Collaboration reports signs of this elusive effect in the collisions of ultra-relativistic lead ions.

While GWAS have uncovered susceptibility loci for B-cell precursor acute lymphoblastic leukemia (BCP-ALL), much of the heritable risk remains undiscovered. Here, the authors perform a meta-analysis of two existing BCP-ALL GWAS together with an unpublished GWAS to identify risk loci at 8q24.21 and 2q22.3.

Rosalind Eeles, Christopher Haiman and colleagues report genome-wide association and meta-analyses of prostate cancer in populations of European, African, Japanese and Latino ancestry. They identify 23 new susceptibility loci, including one associated with early-onset prostate cancer.

Classical Hodgkin lymphoma is a cancer that originates in lymph nodes. Little is known about its genetic susceptibility. Here, the authors combined existing and new genome-wide association studies to identify risk loci for classical Hodgkin lymphoma at 6q22.33, and nodular sclerosis Hodgkin lymphoma at 3q28, 6q23.3, 10p14, 13q34, 16p13.13.
