Advanced Science, EarlyView.Mesoporous mixed ionic‐electronic PU/PEDOT: PSS electrodes enable label‐free detection of stochastic extracellular bioelectrical dynamics in living Phaeodactylum tricornutum. Living diatoms actively modulate interfacial ionic dynamics, establishing stochastic electrochemical noise as a sensitive probe of microbial bioelectrochemical activity and a new ...

Advanced Science, EarlyView.Macrophage RSAD2 dually regulates CMPK2—the rate‐limiting enzyme for mitochondrial DNA synthesis—by suppressing its ubiquitination and promoting its phosphorylation via Csnk2a2 recruitment. This amplifies mtDNA production, which simultaneously activates a cGAS‐STING‐IRF3‐RSAD2 feedforward loop and the NLRP3 inflammasome, driving a self‐sustaining ...

Radiation hydrodynamics of star-disc collisions for quasi-periodic eruptions
Astronomy & AstrophysicsContext. Quasi-periodic eruptions (QPEs) are recently discovered transients of an unknown nature that occur near supermassive black holes and feature bright X-ray bursts separated by hours to days.

Advanced Science, EarlyView.In an invasive beetle–fungus complex, the mutualist Leptographium procerum induces host HSP83 and modulates Toll‐dependent antifungal immunity. HSP83 mediates two‐tiered control by associating with selected fungal recognition receptors and restraining Dorsal‐driven antimicrobial peptide transcription.

The formation of electrostatic shocks in quantum plasmas with relativistically degenerate electrons [PDF]
, 2012 The formation of electrostatic shocks in a super-dense plasma composed of relativistically degenerate electrons and fully ionized ions is theoretically investigated.

The Inner and Outer Shock Layers of Bow Shocks in Cataclysmic Variables
The Astrophysical Journal LettersBow shocks around cataclysmic variables (CVs) have traditionally been identified with a single bright optical arc. This feature has been interpreted as the bow shock formed by the interaction between a sustained outflow and the interstellar medium (ISM).

Astronomy & AstrophysicsStellar mergers produce “explosive outflows” that serve as transient sources of infrared line luminosity and inject mechanical energy early into the natal molecular cloud. We present the first velocity-resolved, sub-km s−1 resolution maps of the [O I] 63

Advanced Science, EarlyView.To model a nutrient‐restricted tumor microenvironment, breast cancer cells were adapted to low glucose and glutamine levels. In the adapted cells, BRD4‐driven enhancer activation increases pro‐invasive EDN1 expression, facilitated by ATF3/c‐JUN and reinforced by enhancer RNA.

Advanced Science, EarlyView.Glucocorticoids (GC) are widely used to reduce inflammation. We show that the glucocorticoid receptor in myeloid cells regulates macrophage cell cycle and genome integrity during muscle regeneration. We demonstrate that dexamethasone administration during the early inflammatory phase delays muscle repair by increasing macrophage proliferation ...

Discovery of a Bow-shock Nebula Around the Z Cam-type Cataclysmic Variable SY Cancri
The Astronomical JournalWe report the serendipitous discovery of a bow-shock nebula around the cataclysmic variable (CV) SY Cancri. In addition, SY Cnc lies near the edge of a faint H α -emitting nebula with a diameter of about $15^{\prime} $ .
