Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Atomic force microscopy of plant chromosomes
Atomic force microscopy has been used to image plant chromosomes from standard preparations without staining or coating. This has enabled the collection of high-resolution three-dimensional data on surface structure. The technique has been further applied to the imaging of C-banded chromosomes revealing structural changes resulting from the banding ...

Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Multifunctional hydrogel nano-probes for atomic force microscopy
Atomic force microscopy typically employs hard tips to map the surface topology of a sample, with sub-nanometre resolution. Here, the authors instead develop softer hydrogel probes, which show potential for multifunctional measurement capabilities beyond

Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Atomic force microscopy in ophthalmic surgery
Refractive errors are some of the most common ophthalmic abnormalities. The introduction of excimer laser technology in refractive corneal surgery aims to eliminate all or the major part of the first corneal surface optical aberrations through the modelling of the corneal surface.

UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.
