JWST imaged three of the gas giants orbiting the star HR 8799 to study their atmospheres. The uniform enrichment of heavy elements, including sulfur, indicates that they formed like Jupiter and Saturn by accreting a lot of icy and rocky solids.

Baretić and Missoury et al. identify vertebrate proteins FAM118B and FAM118A as sirtuins similar to bacterial antiphage enzymes and show that FAM118A/B processing of NAD involves head-to-tail filament formation and a partnership between the two paralogs.

Legislation may appear to provide a breeding ground for monopoly power and profit among commercial seedpropagators, but farmers are canny consumers.

A region on chromosome 19p13 is associated with the risk of developing ovarian and breast cancer. Here, the authors genotyped SNPs in this region in thousands of breast and ovarian cancer patients and identified SNPs associated with three genes, which were analysed with functional studies.

Neuroinflammation is observed in Alzheimer’s disease. Here the authors show that 15 proteins related to inflammation found in CSF can potentially be used as a prognostic biomarker.

Fine-mapping of causal variants and integration of epigenetic and chromatin conformation data identify likely target genes for 150 breast cancer risk regions.

Analysis of multiple species of sponge-dwelling, snapping shrimp reveals pair-forming, communal and eusocial species, suggestive of evolution of eusociality via a ‘family-centred model’, paralleling insects and vertebrates.

This study supports neurofilament light chain protein (NfL) in both cerebrospinal fluid (CSF) and blood as an early marker of neurodegeneration in Alzheimer’s disease but suggests that NfL in CSF may be better suited than blood for monitoring clinical trial outcomes in symptomatic patients.

Asymmetrical distribution of tau pathology in Alzheimer’s disease is linked to asymmetrical amyloid-beta deposition, not reduced brain connectivity, suggesting regional vulnerability plays a key role in determining the distribution of tau pathology.

GIANT, a genetically informed brain atlas, integrates genetic heritability with neuroanatomy. It shows strong neuroanatomical validity and surpasses traditional atlases in discovery power for brain imaging genomics.

Fluorescence polarization (FP) equilibrium binding assays differ from other types of binding studies in one important regard: they require no steps to separate free from bound tracer and are therefore fast, simple and accurate.

Proteomic analysis of cerebrospinal fluid from individuals with autosomal dominant Alzheimer’s disease reveals how this complex and chronic disease evolves over many decades.

Site-specific hyperphosphorylations of tau in the cerebrospinal fluid change with disease course, and correlate with pathology and cognitive decline in dominantly inherited Alzheimer’s disease.

Michael Talkowski and colleagues analyze balanced chromosomal abnormalities in 273 individuals by whole-genome sequencing. Their findings suggest that sequence-level resolution improves prediction of clinical outcomes for balanced rearrangements and provides insight into pathogenic mechanisms such as altered gene regulation due to changes in chromosome topology.

The James Webb Space Telescope has detected water ice in the cold debris disk (analogous to the Kuiper belt) around the star HD 181327.

Cerebrospinal fluid measures of isoform-specific tau species from the microtubule-binding region serve as the first fluid biomarkers of primary tauopathy.

Results from the phase 2/3 clinical trial of gantenerumab or solanezumab in dominantly inherited Alzheimer’s disease reveal no beneficial effects on cognitive measures despite a significant reduction in amyloid plaques and other key biomarkers in those treated with gantenerumab.

Ecosystem services provided by dung beetles are an underappreciated component of terrestrial ecosystems. Here, the authors report a standardized distributed experiment which shows that dung removal rate, a key ecosystem process in pastures, is greater under high beetle functional diversity regardless of grazing intensity.

A rare case of asymptomatic dominantly inherited Alzheimer’s reveals confined tau pathology and unique proteomic features, highlighting potential resilience mechanisms decades beyond expected onset.

Nutrient-starved tumour cells cooperate by secreting aminopeptidases that digest oligopeptides in the microenvironment, creating a shared pool of free amino acids.

Perivascular and leptomeningeal macrophages, collectively termed here parenchymal border macrophages, are shown to regulate flow dynamics of cerebrospinal fluid, implicating this cell population as new therapeutic targets in neurological diseases such as Alzheimer’s.

Alzheimer’s disease has been associated with increased structural brain aging. Here the authors describe a model that predicts brain aging from resting state functional connectivity data, and demonstrate this is accelerated in individuals with pre-clinical familial Alzheimer’s disease.

Breast cancer risk for BRCA1/BRCA2 mutation carriers varies depending on other genetic factors. Here, the authors perform a case-only genome-wide association study and highlight novel loci associated with breast cancer risk for BRCA1/BRCA2 mutation carriers.

A search for transient dark matter in the form of domain walls of axion-like particles finds no statistically significant signal. This places constraints on our theoretical understanding of such scenarios.

The InSight lander has expanded our knowledge of the atmosphere of Mars by observing various phenomena, including airglow, bores, infrasound and Earth-like turbulence.

Targeted therapies matched to genomics improved progression-free survival when genomic alterations were classified as level I/II (according to ESCAT), and genomics should thus be driven by target actionability in patients with metastatic breast cancer.

He et al. develop a network-based metric of amyloid-β burden by integrating individualized brain connectomes with amyloid-PET imaging. This approach improves prediction of future cognitive decline in older adults and may support earlier identification of individuals at risk of dementia.

The Dominantly Inherited Alzheimer Network neuroimaging repository is a free resource consisting of PET and MRI scans from 533 individuals across 206 families who are deeply phenotyped with genetic, clinical, cognitive and biofluid sampling.

The elastic properties of alloys are typically insensitive to changes in microstructure. Here, an as-cast Al-Ce alloy achieves a large Young’s modulus of approximately 92 GPa, due to the presence of isotropic, high symmetry secondary phase.

Roger Milne and colleagues conduct a genome-wide association study for estrogen receptor (ER)-negative breast cancer combined with BRCA1 mutation carriers in a large cohort. They identify ten new risk variants and find high genetic correlation between breast cancer risk for BRCA1 mutation carriers and risk of ER-negative breast cancer in the general population.

Roman et al. demonstrate that crosslinking and contraction of myofibrils mediate the movement of nuclei to the periphery of myofibres, and describe a role for Arp2/3 in organizing desmin.
