Multi-dimensional simulations of bow shocks of massive, high-velocity runaway stars [PDF]
, 2023 Stellar bow shocks result from the supersonic collision of stellar winds ejected by runaway stars and the interstellar medium (ISM). Studying their properties provides constraints on mass-loss rates, stellar wind velocities and the properties of the ISM.

OsCPK12‐OsATPD1 Module Regulates Photosynthetic Acclimation to Light Stress in Rice
Advanced Science, EarlyView.OsCPK12 interacts and phosphorylates OsAtpD1 at Ser8 in its transit peptide. This phosphorylation promote its chloroplast translocation, thereby maintaining ATP synthase activity and proton gradient (ΔpH) homeostasis and regulating photosynthetic acclimation, photoprotection, and repair under light stress.

Advanced Science, EarlyView.AM symbiosis induces GhWAK13 to promote fungal colonization. GhNTF3 negatively regulates symbiosis by promoting SA biosynthesis. GhWAK13 sequesters GhNTF3 at the membrane, limiting its nuclear translocation and relieving SA‐mediated suppression. Under Verticillium stress, GhNTF3 enters the nucleus and interacts with GhJAZ6 to activate SA signaling ...

Streams and Bubbles: Tidal Shaping of Hydrodynamic Planetary Outflows
The Astrophysical JournalPlanets, especially those close to their host stars, lose mass to atmospheric outflows, a process that is thought to shape the bimodal population of gaseous giant and rocky terrestrial exoplanets in close orbits.

A Synthetic Platform for Antibody Junctional Diversification Beyond Natural Constraints
Advanced Science, EarlyView.ARESEC is a synthetic platform that reconstructs functional V(D)J recombination in HEK293T cells. By introducing RSS elements and co‐expressing RAG1/2 and TdT across all three antibody CDRs, it enables programmable junctional diversification and direct generation of high‐affinity variants targeting PD‐1/PD‐L1, overcoming the evolutionary constraints of

Interstellar Ultraviolet Lyα High Resolution Mapping from the New Horizons P-Alice Instrument
The Astronomical JournalWe present New Horizons Alice spectral observations of interstellar hydrogen Ly α emissions at a vantage point of 57 au from the Sun. The observations were conducted as a pair of orthogonal scans to produce high spatial angular resolution measurements of
