Programmable Functional Silicification of DNA Origami Nanostructures
This work introduces additional functionality into silica‐coated DNA origami nanostructures using non‐standard silica precursors. A fluorescent precursor enables enhanced intracellular tracking, while a disulfide‐containing reagent yields redox‐responsive, degradable silica coatings.

Stellar coronal mass ejections (CMEs) have significant impacts on surrounding exoplanets and stellar evolution. For M-type dwarf stars, hosting close-in habitable zones, frequent and intense stellar CMEs may render their potentially habitable planets ...

Stellar Coronae And Chromospheres In The Era Of Asteroseismology
Stellar magnetic activity is an important parameter to study as it can give insights into stellar activity cycles and even how the stellar dynamo operates. However, as cool stars evolve along the main sequence, they lose angular momentum due to magnetic braking.

Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

ASTROPHYSICAL PLASMA PHYSICS: UNDERSTANDING THE BEHAVIOR OF MATTER IN EXTREME ENVIRONMENTS
Astrophysical plasmas—constituting over 99% of visible matter in the universe—exhibit complex behaviors governed by electromagnetic forces, thermodynamic gradients, and dynamic particle interactions, particularly in extreme environments such as stellar ...

Protein Corona Formation on Soft Nanocarriers Under Biomimetic Circulatory Flow
A biomimetic venous circulation system is developed to study protein corona formation on soft nanocarriers under physiological shear. Liposomes, PLGA nanoparticles, and lipid‐polymer hybrid nanoparticles acquire largely shared but material‐dependent protein coronas that alter surface properties and suppress cellular uptake, highlighting the importance ...
