World’s biggest digital camera will repeatedly scan the sky, spotting cosmic explosions while building up a deep map of billions of galaxies

Recent studies suggest that copy number variants (CNVs) may contribute to the missing heritability of complex diseases such as Alzheimer's disease (AD) and related dementias (ADRD). We performed a CNV analysis using genotyping data (Axiom 815 K Spanish biobank array) from the GR@ACE/DEGESCO dementia dataset (n = 20,067) of the Spanish population. Applying PennCNV and extensive quality control, 8275 controls and 7818 dementia cases were selected for gene-level case/control associations. We...

The gut microbiome is emerging as a modifier of risk for neurodegenerative diseases, but underlying mechanisms remain poorly understood. Here, we show that the hTau.P301S mouse model for progressive tauopathy develops alterations in the composition and function of the gut microbiome that are not recapitulated in amyloid-based 5xFAD or 3xTg models for Alzheimer's disease. Disrupting the gut microbiome via chronic antibiotic treatment exacerbates cognitive deficits and tau pathology in hTau.P301S...

BACKGROUND: Rapid population ageing presents one of the defining global health challenges of the twenty-first century. While digital technologies are increasingly used to support older adults, their deployment often remains fragmented, inequitable, and insufficiently guided by ethical and legal frameworks. This paper proposes an integrated policy agenda for healthy longevity, based on the interdisciplinary work of the Einstein Circle Longevity - Healthy Ageing Assisted by Digital Technologies.

With global population aging, sarcopenia and osteoporosis have become critical public health challenges. Muscles and bones are closely interconnected anatomically and functionally, but the biological mechanisms connecting sarcopenia and osteoporosis have not yet been fully elucidated. This study systematically investigated the bidirectional relationship and shared mechanisms between sarcopenia and osteoporosis through multi-omics analysis integrating genomic, proteomic, and metabolomic data from...

KLHL14, a component of an E3-ubiquitin ligase complex, has emerged as a context-dependent oncogene or tumor suppressor, particularly important for thyroid development. Yet its role in thyroid biology remains largely unexplored. In this study, we uncover a central function for KLHL14 in maintaining thyroid epithelial identity and regulating tissue homeostasis. Using a thyroid organoid model, we show that KLHL14 is essential for the proper growth and maturation of thyroid cells. Reduction of...

Age-related cognitive decline in learning and decision-making may arise from increased variability of neural responses. Here, we investigated how ageing affects behavioural and neural variability by recording >18,000 neurons across 16 brain regions (including cortex, hippocampus, thalamus, midbrain, and basal ganglia) in younger and older mice performing a visual decision-making task. Older mice showed more variable response times, reproducing a common finding in human ageing studies. Ageing...

The developmental history of a cell fundamentally defines its identity and function. Recent advances in cell lineage tracing now enable high-resolution reconstruction of cellular ancestries in vivo, illuminating how lineage dictates fate in health and disease. This Review highlights recently developed tools, ranging from refined recombinase systems to advanced synthetic and natural barcoding approaches, that facilitate the investigation of pathological lineage programs in cancer, cardiovascular...

Immunotherapy against amyloid β-protein (Aβ) for Alzheimer's disease (AD) has been widely approved. Breakthrough disease-modifying treatments such as lecanemab and donanemab are often followed by drugs with improved efficacy. By immunizing Trianni mice with aggregated synthetic Aβ, we obtained B28, a fully human antibody specifically selected for its neutralization of tau neuritic dystrophy induced by AD brain-derived oligomers. In a blinded trial in mutant human APP^(NL-G-F) knock-in mice,...

Prion diseases represent a unique biological paradigm with mechanistic parallels to other neurodegenerative conditions like Alzheimer's and Parkinson's diseases. However, the study of human prion pathobiology and the development of effective therapeutics has been severely constrained by the inability to propagate human prions in dividing cells-forcing reliance on costly and slow animal bioassays. Here, we report the generation of EKV cells-a humanized cell model which supports the robust,...

Mitochondrial damage is a shared hallmark of brain aging and neurodegeneration. While pathological Tau mutations disrupt mitochondrial dynamics and function, the physiological role of wild-type (WT) Tau in the maintenance of mitochondrial homeostasis remains poorly understood. Here, using Caenorhabditis elegans and mice lacking PTL-1, the nematode Tau-like homolog, and Tau respectively, we demonstrate that Tau deficiency promotes a shift toward a pro-fusion mitochondrial state associated with...

Aging is associated with reduced venous compliance and altered muscle pump function, though how these features impact venous return during volume-stressed conditions remains poorly characterized. We examined lower-limb venous flow dynamics and muscle pump efficiency between healthy younger (YA) and older adults (OA) under two volume-stressed conditions. Fourteen YA (7F, 26 ± 4 years) and fourteen OA (9F, 76 ± 6 years) underwent assessments at head-down tilt (HDT, -3°) and head-up tilt (HUT, +...

Investigating age-associated changes in intestine and understanding immune-related intestinal dysfunctions is essential for promoting healthy ageing. Mucosal surfaces represent a distinct immune compartment enriched with specialised lymphocytes that interact dynamically with the epithelial layer. In this study, we present novel spatially resolved insights into the cellular and molecular alterations in the ageing murine gut mucosa. Our findings reveal a complex network of interdependent...

T cell output from the thymus falls throughout life and is associated with profound remodeling of the thymic stroma. To what extent the decline in T cell output is caused by aging of the hematopoietic stem and progenitor cells (HSPCs) has been difficult to define because of HSPC heterogeneity, the multi-stage process of HSPC migration, and the cross-talk between hematopoietic and stromal elements of the thymus. To address the contribution of HSPC aging on T cell development, we interrogated T...

CONCLUSION: These findings identify oxidative stress and disrupted autophagy as key mediators of saturated-fat-induced neuronal decline and highlight a sex-specific vulnerability to dietary fat composition. This work establishes Drosophila as a powerful model for dissecting nutritional drivers of neural aging and suggests that metabolic stress pathways represent critical early targets in diet-associated neurodegeneration.

CONCLUSIONS: Personal EHR engagement among the vulnerable aging population is influenced by a complex interplay of patient, HCP, and technology-related factors, which must be addressed holistically to ensure inclusive usage and adherence to digital health tools.

A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow the disease's relentless progression.
