Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

Networks of miniaturized magnetoelectric wireless implantable devices can be individually powered and controlled by a single transmitter, show power and transfer data efficiencies that scale with the number of receivers and be used for spinal cord stimulation and cardiac pacing in large animals.

Chemical doping allows for boosting the conductivity in conjugated polymers but the relationship between doping and the polymers’ complex, multiscale morphology remains elusive. Here the authors report that supramolecular chirality, which up to now had not been considered a parameter relevant to doping, significantly boosts the underpinning redox reaction in conjugated polymer thin films.

Genome-wide analyses identify 30 independent loci associated with obsessive–compulsive disorder, highlighting genetic overlap with other psychiatric disorders and implicating putative effector genes and cell types contributing to its etiology.

This study used fine-mapping to analyze genetic regions associated with bipolar disorder, identifying specific risk genes and providing new insights into the biology of the condition that may guide future research and treatment approaches.

Whether multimorbidity accelerates brain Aβ deposition in humans remains largely unknown. Here, the authors demonstrate that higher self-reported multimorbidity burden predicts increased brain Aβ accumulation rates in the ADNI cohort.

Using multi-ancestry genome-wide association study and fine-mapping, 298 loci and 36 credible genes are identified in the aetiology of bipolar disorder.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

Countries should follow China's lead and boost markets for water, wind and solar power technologies to drive down costs, say John A. Mathews and Hao Tan.

Systematic analysis from the Global Burden of Disease study reported that, despite global improvements from 1990 to 2021, dietary iron deficiency-associated disease burden remains high in women, children and residents in low socio-demographic index countries.

The country consumes the most resources in the world and produces the most waste — but it also has the most advanced solutions, say John A. Mathews and Hao Tan.

Genome-wide association analyses of 41,917 bipolar disorder cases and 371,549 controls of European ancestry provide new insights into the etiology of this disorder and identify novel therapeutic leads and potential opportunities for drug repurposing.

Dendritic distortion is problematic for neurons using temporal coding strategies, such as medial superior olivary neurons, which encode microsecond differences in binaural auditory input. Mathews et al. find that both the specific activation properties and spatial distribution of K_v1 channels compensate for passive cable filtering, helping to preserve binaural synaptic timing.

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.

This study finds that sST2 is a disease-causing factor for Alzheimer’s disease. Higher sST2 levels impair microglial Aβ clearance in APOE4⁺ female individuals. A genetic variant, rs1921622, is associated with a reduction in sST2 level and protects against AD in APOE4⁺ female individuals.

Sun et al. report human lifespan changes in the brain’s functional connectome in 33,250 individuals, which highlights critical growth milestones and distinct maturation patterns and offers a normative reference for development, aging and diseases.

No preventive treatment addresses the underlying condition that leads to cardiac arrest. Here, researchers developed an injectable hydrogel electrode that achieves pacing that mimics physiological conduction with the potential to eliminate lethal arrhythmias and provide painless defibrillation.

The interplay between amyloid and tau pathology in Alzheimer’s disease is still not well understood. Here, the authors show that amyloid-related increased in soluble p-tau is related to subsequent accumulation of tau aggregates and cognitive decline in early stage of the disease.

A study describes the metabolic adaptations supporting differentiation, survival and function of tissue-resident memory CD8⁺ T cells and how to leverage them to enhance immunity against pathogens and tumours.

In this study the authors identify a possible link between the gene FAM222A and brain atrophy. The protein it encodes is found to accumulate in plaques seen in Alzheimer’s disease, and functional analysis suggests it interacts with amyloid-beta.

As various advisory bodies, scientific organizations and funding agencies deliberate on genome editing in humans, Debra J. H. Mathews, Robin Lovell-Badge and colleagues lay out some key points for consideration.

Despite the impressive demonstrations with silicon and oxide memristors, realizing efficient roots of trust for resource-constrained hardware remains a challenge. Here, the authors exploit switching behavior in one dimensional perovskite memristors to design security primitives for key generation and device authentication.

Accomplishing complex cognitive tasks such as speech recognition calls for artificial intelligence hardware with high computing precision. John et al. propose deep recurrent neural networks based on optoelectronic transition metal dichalcogenide memristors with high weight precision for in-memory computing.

The dysfunction of IL-10 secreting regulatory B cells has been linked to the pathogenesis of autoimmune disease. Here the authors show that low dose IL-2 therapy can enhance IL-10 production in regulatory B cell populations via the modulation of BACH2.

This Resource describes data, code and tools developed for the Human Reference Atlas and the Human BioMolecular Atlas Program for building and navigating a multiscale human atlas.

Alzheimer’s disease is heterogeneous in its neuroimaging and clinical phenotypes. Here the authors present a semi-supervised deep learning method, Smile-GAN, to show four neurodegenerative patterns and two progression pathways providing prognostic and clinical information.

Systematic characterization of longitudinal tau variability in human Alzheimer’s disease using an unbiased subtyping algorithm reveals four trajectories of tau deposition with distinct clinical features.

The KL-VS haplotype of the Klotho gene has been associated with reduced risk of Alzheimer’s disease and dementia. Here the authors show an association between the KL-VS haplotype and amyloid-dependent tau accumulation using PET data.

Nucleotides are essential for different biological processes and have been also associated to cancer development. Depleting cellular nucleotides is a strategy commonly employed to target cancers. Here, the authors show that purine depletion induces serine synthesis to promote cancer cell migration and metastasis.

Lineage tracing analyses of cells from two monozygotic twins presenting with myelofibrosis in adulthood provide evidence of in utero transplacental transmission of the tumorigenic clone.

The BIN1 SNP rs744373 is associated with higher CSF tau and phosphorylated tau levels. Here the authors show, using PET imaging, that this SNP is associated with tau accumulation in the brain as well as impaired memory in older individuals without dementia.
