Although river protection is core to social and environmental well-being, the extent to which river conservation policies are effective is difficult to assess. This study reveals that, under all relevant protection mechanisms in the contiguous USA, only 12% of rivers are adequately protected.

Here the authors analyse genetic data for over 400,000 British and Irish people, showing that the frequency of the major genetic risk factor for haemochromatosis varies from a low of 1/212 in Southern England to 1/62-1/54 in Outer Hebrideans and Northwest Irish. Clinically diagnosed haemochromatosis varies 11- fold in frequency across England, emphasising the uneven risk landscape.

Krisai et al. compare brain structure and cognitive function in elderly patients with and without atrial fibrillation using brain MRI and cognitive testing. They find that atrial fibrillation is associated with more brain lesions and lower cognitive function, but the cognitive impairment occurs primarily through direct effects of the arrhythmia rather than through brain damage.

CD38 is highly expressed by antibody-secreting cells (ASC) and depleting antibodies targeting CD38 have the potential to treat autoimmune diseases with ASC involvement. Here authors treat systemic lupus erythematosus patients with the ASC-depleting anti-CD38 monoclonal antibody daratumumab in addition to dexamethasone in the frame of a single arm, open-label phase 2 clinical trial to show marked improvements in their clinical and immunological status.

Non-invasive strategies to detect and track activated myeloid cells will facilitate disease diagnosis and monitoring in patients affected by neuroinflammatory disorders.

Patients with myelodysplastic syndromes (MDS) have limited therapeutic options. Here the authors show that functionally impaired NK cells contribute to immune escape of pre-malignant clones in early stage MDS and that NK adoptive cell therapy can be considered to prevent or delay the development of MDS.

This report describes a nanobody targeting glycine receptor mGlyR that inhibits its ability to regulate G protein signaling and produces anti-depressant effects in mice providing an immunotherapy approach to potentially treat depression.

Donahue et al. show that ageing is associated with changes in ER morphology. ER-phagy drives age-associated ER remodelling through tissue-specific factors.

The role of normally silenced transposable elements (TEs) in tumorigenesis remains unclear. Here, the authors show that increased expression of TEs in both patients and mice with colitis or by DNA hypomethylating drugs elicits a viral mimicry response that suppresses tumorigenesis. This viral mimicry response inhibits the stemness of cancer initiating cells in a cell autonomous manner.

Biodegradable enzymatic microbubble robots self-propel in urea, are magnetically or chemotactically guided, provide ultrasound imaging and enhance intratumoural drug delivery with focused ultrasound.

A large cross-population atlas of gene–environment interactions reveals how age, sex and lifestyle shape genetic effects, heritability, prediction accuracy and disease biology, with implications for personalized medicine and drug development.

The hepatitis B virus surface protein recognizes host entry receptor via its intrinsically disordered peptide. The authors reveal the dynamic process of the viral surface protein that involves a stepwise binding maturation for establishing high affinity and specific virus-receptor entry complex.

Juvenile idiopathic arthritis (JIA) associated uveitis can cause vision loss in children, but mechanisms remain unclear. The authors here identify elevated CD19⁺IgD^-CD27^- double negative type 1 B cells in JIA-uveitis and show that targeting B-T cell interactions suppresses disease in mouse models of uveitis.

Elite and viremic controllers of HIV can spontaneously regulate viral replication, but some lose this ability over time. In this longitudinal cohort study, 31% of viremic and 3% of elite HIV controllers lost viral control over 17 years. Specific T-cell– related proteins distinguish controller types and predict loss years in advance.
