A perspective on active glassy dynamics in biological systems
Dynamics is central to living systems. In the last two decades, experiments have revealed that the dynamics in diverse biological systems - from intracellular cytoplasm to cellular and organismal aggregates - are remarkably similar to that in dense systems of inanimate particles in equilibrium. They show a glass transition from a solid-like jammed state to a fluid-like flowing state, where a moderate change in control parameter leads to an enormous variation in relaxation time. However, biologi…

Current-density-modulated Antiferromagnetic Domain Switching Revealed by Optical Imaging in Pt/CoO(001) Bilayer
Efficient control of antiferromagnetic (AFM) domain switching in thin films is vital for advancing antiferromagnet-based memory devices. In this study, we directly observed the current-driven switching process of CoO AFM domains in the Pt/CoO(001) bilayer by the magneto-optical birefringence effect. The observed critical current density for AFM domain switching remains nearly constant across varying CoO thicknesses, associated with the consistent switching polarity n $\perp$ j, suggesting the d…

TikTok users with stigmatized interests or marginalized identities express anxiety over its potential ban, as rebuilding their communities elsewhere may be hard (Washington Post)

They found safe spaces on TikTok. A ban could devastate their communities.
With President Biden signing a bill that could ban TikTok, groups such as GriefTok and DeafTok fear they’ll lose an inimitable source of comfort and connection.

Raiders QB Gardner Minshew Has Major Free Agency Revelation
Gardner Minshew signed with the Las Vegas Raiders in free agency last month, and he told Raiders edge rusher Maxx Crosby that the Raiders were his top destination all along. “It was my first option,” Minshew said on The Rush podcast. “When we were stacking it up, I think I was their first option. As soon as free agency started, we made the call and that was it. Couldn’t have been easier. I couldn’t have been more excited.” Minshew will join a quarterback room that already includes A…

Stacking X-ray Observations of "Little Red Dots": Implications for their AGN Properties
Recent {\em James Webb Space Telescope (JWST)} observations have revealed a population of compact extragalactic objects at $z\gtrsim4$ with red near-infrared colors, which have been dubbed as ``Little Red Dots" (LRDs). The spectroscopically-selected LRDs exhibit broad H$α$ emission lines, which has led to the conclusion that type-I active galactic nuclei (AGN) are harbored in the galaxies' dust-reddened cores. However, other mechanisms, like strong outflowing winds, could also produce broad H$…

Electron-phonon interaction, magnetic phase transition, charge density waves and resistive switching in VS2 and VSe2 revealed by Yanson point contact spectroscopy
VS2 and VSe2 have attracted particular attention among the transition metals dichalcogenides because of their promising physical properties concerning magnetic ordering, charge density wave (CDW), emergent superconductivity, etc., which are very sensitive to stoichiometry and dimensionality reduction. Yanson point contact (PC) spectroscopic study reveals metallic and nonmetallic states in VS2 PCs, as well as a magnetic phase transition was detected below 25 K. Analysis of PC spectra of VS2 test…
