A new approach to magnetic resonance, ‘magnetic resonance fingerprinting', is reported, which combines a data acquisition scheme with a pattern-recognition algorithm that looks for the ‘fingerprints’ of interest within the data.

A high-bandwidth neuromotor interface offers performant out-of-the-box generalization across people.

Whole-brain anatomical and activity surveys identify the lateral hypothalamus as a key driver of recovery from spinal cord injury, leading to a deep brain stimulation therapy that augments the recovery of walking in humans.

Post-traumatic stress disorder (PTSD) is a common mental health problem. Here, the authors report a GWAS from the Psychiatric Genomics Consortium in which they identify two risk loci in European ancestry and one locus in African ancestry individuals and find that PTSD is genetically correlated with several other psychiatric traits.

Olfactory deficits occur early in Alzheimer’s disease (AD). Here, the authors identify that loss of locus coeruleus axons in the olfactory bulb underlies impaired olfaction in an AD mouse model and provide translational evidence for similar deficits in humans.

Developing clinically predictive model systems for evaluating gene transfer and gene editing technologies has become increasingly important. This study introduces human liver ex situ normothermic perfusion as a model to evaluate gene therapy vectors, paving the way for advanced liver disease treatment.

The role of olfactory pathways in the development of neurodegeneration in Alzheimer’s disease is not well understood. Here, the authors show odor identification deficits are predictive of tau accumulation and progression in olfactory pathways, and that tau spreads from medial temporal lobe structures towards the olfactory system.

By integrating large-scale genomic and proteomic data in cerebrospinal fluid and plasma, the authors identify 49 proteins linked to MRI markers of cerebral small vessel disease, highlighting extracellular matrix and immune pathways, with biomarker and therapeutic potential.

EchoNext, a deep learning model for electrocardiograms trained and validated in diverse health systems, successfully detects many forms of structural heart disease, supporting the potential of artificial intelligence to expand access to heart disease screening at scale.

Disease-monitoring in large vessel vasculitis is challenging, often leading to a mismatch between disease activity and treatment intensity. Here, the authors show that PET/MRI scanning can distinguish active from inactive large vessel vasculitis and track disease longitudinally, potentially allowing more stratified treatment for patients.

Toxicities limit combination of PARP inhibitors (PARPi) and chemotherapy in patients with germline BRCA1 and BRCA2 pathogenic variant (gBRCAm) breast cancer. Here, the authors report a preclinical study followed by a randomised phase II/III clinical trial investigating the addition of a gap between chemotherapy (carboplatin and paclitaxel) and PARPi (olaparib), in patients with early gBRCAm breast cancer.

Post-infectious myalgic encephalomyelitis/chronic fatigue syndrome (PI-ME/CFS) is a disabling disorder, yet the clinical phenotype is poorly defined and the pathophysiology unknown. Here, the authors conduct deep phenotyping of a cohort of PI-ME/CFS patients.

Here, using fMRI the authors show that the human pulvinar has widespread functional coupling with cortical areas that reflects its intrinsic organization and the topographic layout of cortex.

Here, the authors use fMRI to demonstrate that actions are linked to these factors: when people think about states and situations, they average over the representations of the actions they afford.
