Uhlmann et al. show that the preclinical phase of Alzheimer’s disease may in fact be a relatively late manifestation of a much earlier pathogenic and targetable process of seed formation and propagation.

Helices are found at every level of natural systems, where their dynamic potential is exploited to achieve a variety of functions. Here, liquid-crystalline molecular switches embedded in a polymer are used to prepare biomimetic spring-like materials that can convert molecular motion into macroscopic work.

Several recent studies suggest that telomerase has key physiologic functions beyond its well-known role telomere maintenance. Here, Garcia Gonzalez et al. implicate telomerase in the regulation of ribosomal DNA transcription by RNA polymerase I.

Analysis of HbA1c and FPG levels across 117 population-based studies demonstrates regional variation in prevalence of previously undiagnosed screen-detected diabetes using one or both measures and suggests that use of elevated FPG alone could underestimate diabetes prevalence in low- and middle-income countries.

Defective ribonucleotide excision repair causes ID4, an indel cancer signature characterized by deletions of 2–5 base pairs.

Analysis of autosomal recessive coding variants in 29,745 trios from the DDD study and GeneDx provides insights into the genetic architecture of developmental disorders across ancestrally diverse populations.

Turajlic and colleagues assess longitudinal antibody and cellular immune responses against SARS-CoV-2 variants of concern in patients with cancer, following either recovery from SARS-CoV-2 infection or vaccination, in two back-to-back reports from the CAPTURE study.

UDP-glucuronic acid is a component of the extracellular matrix. Here, the authors report biallelic variants in the gene encoding UDP-Glucose 6-Dehydrogenase (UGDH) in individuals affected by developmental epileptic encephalopathies that impair UGDH stability, oligomerization, or enzymatic activity in vitro.

Senegal has initiated a national sentinel surveillance program for malaria parasite genetics. Here, the authors report data from the first year of the program and use it to investigate local malaria incidence, patterns of transmission, and genetic loci under selection.

The heterogeneity of androgen receptor (AR) gene alterations across metastases in prostate cancer remains unresolved. Here, the authors characterise AR genomic complexity across spatially separated lethal metastases from 10 prostate cancer patients and investigate how AR alterations evolve.

Reduced glomerular filtration rate (eGFR) is a hallmark of chronic kidney disease. Here, Pattaro et al. conduct a meta-analysis to discover several new loci associated with variation in eGFR and find that genes associated with eGFR loci often encode proteins potentially related to kidney development.

Impairment of cognitive function is a common feature of many neurodevelopmental disorders. Systems genetics analysis in the brain uncovered a convergent gene network for both cognition and neurodevelopmental disorders. As the network does not recapitulate known pathways, this finding represents a new basis for understanding factors influencing normal and disordered cognition.

From 1980 to 2018, the levels of total and non-high-density lipoprotein cholesterol increased in low- and middle-income countries, especially in east and southeast Asia, and decreased in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe.

Previous studies identified an association between the 2q35 locus and breast cancer. Here, the authors show that a SNP at 2q35, rs4442975, is associated with oestrogen receptor positive disease and suggest that this effect is mediated through the downregulation of a known breast cancer gene, IGFBP5.

Cells with mitochondrial defects are shown to be eliminated by cell competition in the early mouse embryo, thus suggesting that cell competition acts as a purifying selection that optimizes mitochondrial performance during development.

During embryo development, cell fitness determines survival but how this is regulated is unclear. Here, the authors show that in early embryonic development and stem cells exiting the naive state, cells sense the fitness of their neighbours and trigger p53 to repress mTOR to eliminate a third of cells.

Distinguishing clinical subtypes of IBD is critical for optimal treatments, outcome prediction, and better understanding of disease pathogenesis. Here the authors phenotype blood and intestinal immune cells by mass cytometry and identify signatures associated with distinct disease states.

The second plague pandemic, caused by Yersinia pestis, started in the 14th century and recurred in Europe until the 18th century. Here, the authors reconstruct ancient Y. pestis genomes from human remains spanning this period, shedding light into the phylogeography and population structure of the European strains.

Newly emerged pathogens are inherently difficult to forecast, due to many unknowns about their biology early in an epidemic. Here, the authors assess forecasts of a suite of models during the Zika epidemic in Colombia, finding that the models that performed best changed over the course of the epidemic.

Health care workers (HCW) are a high-risk population for SARS-CoV-2 infection. Here, the authors determine seroprevalence against SARS-CoV-2 in HCWs of a large Spanish reference hospital and find a cumulative prevalence of SARS-CoV-2 infection (presence of antibodies or past or current positive rRT-PCR) of 11%.

Analysis of the spread of the 20E (EU1) variant of SARS-CoV-2 through Europe suggests that international travel and insufficient containment, rather than increased transmissibility, led to a resurgence of infections.

Contrary to the view that urbanization is a major driver of the global rise in obesity, the global increase in body-mass index is shown to be mostly due to increases in the body-mass indexes of rural populations.

Doug Easton and colleagues report the results of a large-scale genome-wide association study of breast cancer. They discover 15 new susceptibility loci and highlight likely target genes in several of the newly associated regions.
