Knowledge‐distilled diffusion models for improving cone‐beam CT image quality with meta‐learning under imbalanced data

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Adaptive radiation therapy (ART) relies on daily cone‐beam CT (CBCT), yet its limited image quality hinders accurate dose calculation, particularly under substantial anatomical changes. Purpose To overcome the clinical challenge of scarce paired planning CT (pCT) data versus abundant unpaired CBCTs, we propose a framework driven by ...

Damping amyloid‐associated conformational fluctuations in a protein by an engineered diselenide bridge

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Polypeptide cross‐β assembly, characteristic of diverse proteotoxic diseases, defines a general thermodynamic ground state and limits the shelf lives of peptide‐ and protein therapeutics. A model is provided by insulin. Although the hormone contains a predominance of α‐helix, its fibrils exhibit cross‐β reorganization.

DNA‐Enzyme Hybrid Nanostructures: Functional Materials to Modulate Enzymatic Activity

Small, Volume 22, Issue 43, 3 August 2026.
DNA–enzyme hybrid nanostructures enable precise spatial and stoichiometric control over enzyme organization, offering a powerful platform to modulate catalytic activity. This review critically evaluates key mechanistic hypotheses, including proximity effects, microenvironment changes, confinement, and stabilization, as well as highlighting ...

Highly Chiral MoS2 Flakes With Redox‐Active Centers for Spin Selective Water Oxidation

Small Science, Volume 6, Issue 8, August 2026.
The chiral‐induced spin selectivity effect was realized exploited in Ni‐doped, intrinsically chiral 2D MoS2 flakes to suppress H2O2 production and enhance water oxidation kinetics during water splitting. We propose a hydrothermal synthesis route for highly chiral two‐dimensional flakes of MoS2 doped with single nickel atoms (Ni:MoS2) for spin ...

CbPM Estimates of Net Primary Production in the North Atlantic From Profiling Floats and Satellites Diverge Seasonally Due To Fluorescence and Vertical Extrapolation Effects

Global Biogeochemical Cycles, Volume 40, Issue 8, August 2026.
Abstract Marine net primary production (NPP), defined as the difference between gross production and phytoplankton respiration, is often estimated using algorithms applied to remote sensing data. While assumptions are needed to extend surface satellite observations through depth, some NPP algorithms, like the Carbon‐based Productivity Model (CbPM ...
