Testing modified gravity with globular cluster velocity dispersions
, 2008 Globular clusters (GCs) in the Milky Way have characteristic velocity dispersions that are consistent with the predictions of Newtonian gravity, and may be at odds with Modified Newtonian Dynamics (MOND).

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
Advanced Functional Materials, EarlyView.A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Advanced Healthcare Materials, EarlyView.Membrane vesicles derived from the probiotic Lacticaseibacillus casei BL23 demonstrate antimicrobial properties against Escherichia coli and a potential biological effect in improving the overall survival of C. elegans infected with Pseudomonas aeruginosa. These vesicles stimulated immune responses in primary cells without causing toxicity. Our results

The Gaia inertial reference frame and the tilting of the Milky Way disk
, 2014 While the precise relationship between the Milky Way disk and the symmetry planes of the dark matter halo remains somewhat uncertain, a time-varying disk orientation with respect to an inertial reference frame seems probable.

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization
Advanced Healthcare Materials, EarlyView.A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Observational Constraints of Radial Migration in the Galactic Disk Driven by the Slowing Bar
The Astrophysical Journal LettersRadial migration is an important dynamical effect that has reshaped the Galactic disk, but its origin has yet to be elucidated. In this work, we present evidence that resonant dragging by the corotation of a decelerating bar could be the main driver of ...

Masses, luminosities and dynamics of galactic molecular clouds [PDF]
Star formation in galaxies takes place in molecular clouds and the Milky Way is the only galaxy in which it is possible to resolve and study the physical properties and star formation activity of individual clouds. The masses, luminosities, dynamics, and

Advanced Healthcare Materials, EarlyView.Human iPSC‐derived hypertrophic chondrocyte sheet promotes bone regeneration. Abstract Bone defects are a major clinical challenge, primarily owing to the limited self‐healing capacity of bones and the high risk of complications associated with conventional treatment strategies.
