HSD17B4 deficiency disrupts peroxisomal metabolism and causes ciliopathy-like phenotypes. Here the authors show that acetyl-CoA restores primary cilia and improves cerebellar defects in Hsd17B4-deficient models, suggesting a potential therapeutic strategy.

Large-scale multivariate analyses across populations of European ancestry identify risk loci for the metabolic syndrome, improving polygenic prediction models and highlighting associations with diverse traits beyond cardiometabolic diseases.

Animals detect microbiomes through smell, aiding communication, group recognition, and behavior. Here with Drosophila model, the authors show that airway and gut cells can sense microbiome-emitted scents independently of smell, promoting host growth.

A genome-wide association meta-analysis study of blood lipid levels in roughly 1.6 million individuals demonstrates the gain of power attained when diverse ancestries are included to improve fine-mapping and polygenic score generation, with gains in locus discovery related to sample size.

The limited operational stability of multi-resonance thermally activated delayed fluorescence emitters often constrains their practical application. Here, the authors report a direct correlation between device lifetime and Faradaic yield for oxidative degradation of emitter molecules.

Current imaging flow cytometry approaches remain limited in their ability to reveal subcellular information with high-resolution and instrumental simplicity. Here, the authors present a light-field flow cytometer capable of high-content, multi-color imaging of cells with high-resolution in 3D.

The Thoeris defense system is a recently discovered bacterial defense system that protects bacteria against phage infection and consists of the two genes thsA and thsB. Here, the authors present the crystal structures of Bacillus cereus ThsA and ThsB and show that ThsA is a NAD⁺ cleaving enzyme.

The lateral septum contains neurons that mediate stress responses, but the role of astrocytes remained unclear. Here, the authors show that lateral septum astrocytes modulate nearby neurons and enhance stress related physiological and behavioral responses.

Detailed knowledge of the characteristics of COVID-19 patients helps with public health planning. Here, the authors use routinely-collected data from seven databases in three countries to describe the characteristics of >30,000 patients admitted with COVID-19 and compare them with those admitted for influenza in previous years.

Previous work proposed the Berry curvature dipole as the mechanism of the nonlinear Hall effect. Lee et al. establish the sign-changing Berry curvature hot spots from spin-orbit split bands as the origin of the Berry curvature dipole and link it to the nonlinear Hall effect in the topological semimetal NbIrTe₄.

A combination of photoemission and scanning tunnelling spectroscopy measurements provide compelling evidence that single layers of 1T'-WTe₂ are a class of quantum spin Hall insulator.

Autophagy is important for pancreatic β-cell function, however, the role of mitophagy and mechanism for mitophagy in β-cells are unclear. Here the authors report that in stressed β-cells, lysosomal Ca²⁺ release promotes mitophagy via activation of the transcription factor EB (TFEB) and loss of β-cell TFEB aggravates glucose intolerance during high-fat diet.

Islet amyloid polypeptide (IAPP) deposition is associated with islet cell loss in diabetes. Here the authors show that a small molecule autophagy enhancer reduces IAPP accumulation in vitro, and also improves glucose tolerance in hIAPP⁺ mice fed high-fat diet, accompanied by reduced hIAPP accumulation, in vivo.

The control of magnetism by electric field is an important goal for future development of low-power spintronics. Here, the authors demonstrate voltage control of magnetism in van der Waals ferromagnetic/ferroelectric heterostructure devices via the strain-mediated magnetoelectric effect.

The electrons that contribute to the Mott insulator state in single-layer 1T-TaSe2 are shown to also have a rich variation in their orbital occupation. As more layers are added, both the insulating state and orbital texture weaken.

Unconventional quasiparticles carrying spin but not electric charge emerge in quantum spin liquid phases. The Kondo interaction of these spinon quasiparticles with magnetic impurities may now have been observed.

C. elegans show a dispersal behavior called nictation. The authors show that this is regulated by the ciliated neuron IL2 and requires cholinergic transmission.
