VLBI Analysis of a Potential High-Energy Neutrino Emitter Blazar
UniverseRecent studies suggest that high-energy neutrinos can be produced in the jets of blazars, radio-loud active galactic nuclei (AGN) with jets pointing close to the line of sight.

Biomimetic Dynamics of Nanoscale Groove and Ridge Topography for Stem Cell Regulation
Advanced Materials, EarlyView.Dynamic nanoscale groove‐ridge structures are engineered by flexibly conjugating RGD‐magnetic nanoparticles to nanogroove templates with variable groove widths at the molecular scale. Magnetic control enables cyclic switching between nanoscale groove and ridge states that modulates ligand accessibility of cellular integrins.

Brightness and shape of radio jets
The Astrophysical Journal, 1979 Observed radio structures of jets in radio galaxies are compared with models based on beam and slingshot theories. Simple beam models predict a rapid decline of surface brightness B with distance r from the nucleus, Bproportionalr/sup -m/, where m>3. This contrasts with the almost uniform brightness out to 200 kpc in the jet of NGC 6251 and out to 10 ...
