Analysis of embryonic lethal and sub-viable mouse knockout lines reveals that ablation of many genes affects placental development, and that the occurrence of placental defects is co-associated with abnormal brain, heart and vascular system development.

Fernando Rivadeneira and colleagues in the Genetic Factors for Osteoporosis Consortium report a large-scale meta-analysis identifying new loci associated with bone mineral density (BMD) and risk of fracture. Thirty-two new loci are found to be associated with BMD, and 6 loci confer higher risk for low-trauma bone fracture.

Circulating lipoprotein(a) is an important risk factor for cardiovascular disease and shows variability between different ethnic groups. Here, Zekavat et al. perform whole-genome sequencing in individuals of European and African ancestries and find ancestry-specific genetic determinants for lipoprotein(a) levels.

Empirically based models of disease progression in familial frontotemporal dementia reveal the relative ordering of clinical, neuroimaging, and fluid biomarker changes and facilitate novel clinical trial designs

Although the common genetic variants contributing to blood lipid levels have been studied, the contribution of rare variants is less understood. Here, the authors perform a rare coding and noncoding variant association study of blood lipid levels using whole genome sequencing data.

Susan Slager and colleagues report a meta-analysis of genome-wide association studies for chronic lymphocytic leukemia (CLL). They identify nine loci newly associated with CLL.

An international consortium reports the genomic sequence for ten Drosophila species, and compares them to two other previously published Drosophila species. These data are invaluable for drawing evolutionary conclusions across an entire phylogeny of species at once.

A phase I dose-escalation trial of GD2-CAR T cells in children and young adults with diffuse midline gliomas to assess the feasibility of manufacturing, safety and tolerability, and to preliminarily assess efficacy.

Although fluctuations in annual temperature have shown substantial geographical variation over the past few decades, which may be more difficult for society to adapt to than altered mean conditions, the time-evolving standard deviation of globally averaged temperature anomalies reveals that there has been little change.

Solid stress generated by brain tumours can cause neurological dysfunction in patients, and this could be countered by administering lithium, according to magnetic resonance imaging of patient brains and mouse models of human brain tumours.

Here the authors assess the B and T cells of a cohort of UK healthcare workers in response to infection and longitudinally track the compartment showing distinct trajectories following early priming.

Malignant pleural effusion (MPE) is a life-threatening cancer-related disorder. Here, the authors show that KRAS-mutant tumor cells require IKKα, activated via host-provided IL-1β, to promote MPE development and that co-inhibition of both KRAS and IKKα ameliorates the development of MPE in mouse models.
