Annalen der Physik, Volume 538, Issue 6, June 2026.This study examines slowly rotating traversable wormholes supported by string fluids whose properties change with radius. The matter smoothly shifts from a de Sitter‐like core to a string‐dominated exterior, producing a regular, horizon‐free spacetime.

The Impacts of Bars, Spirals, and Bulge Size on Gas-phase Metallicity Gradients in MaNGA Galaxies
The Astrophysical JournalAs galaxies evolve over time, the orbits of their constituent stars are expected to change in size and shape, moving stars away from their birth radius. Radial gas flows are also expected. Spiral arms and bars in galaxies are predicted to help drive this

Advanced Science, Volume 13, Issue 28, 18 May 2026.The 3K‐AP system forms infinite supramolecular fibrils that undergo controlled degradation into shorter fragments upon enzymatic hydrolysis. Multitechnique imaging reveals a stepwise bacteriolytic mechanism involving bacterial entrapment, disassembly into lethal constructs, and associated extracellular vesicle release, highlighting the dynamic ...

The Abundance and Properties of Barred Galaxies out to z ∼ 4 Using JWST CEERS Data
The Astrophysical JournalWe present the first estimate of the observed fraction and properties of bars out to z ∼ 4 using JWST CEERS NIRCam images. We analyze 1770 galaxies with M _⋆ > 10 ^10 M _⊙ at 0.5 ≤ z ≤ 4 and identify barred galaxies from 839 moderately inclined disk ...

Spatial Analysis of Tropical Cyclone Precipitation Through Landfall: A Multi‐Basin Perspective
Meteorological Applications, Volume 33, Issue 3, May/June 2026.We use a shape metric methodology to analyze the spatial evolution of tropical cyclone (TC) precipitation across the North Indian, Western Pacific, and North Atlantic basins. Across all basins, precipitation area decreases from pre‐landfall to post‐landfall, with closure decreasing and dispersion increasing, indicating an exposed TC center and outward ...

The Astrophysical JournalWe report a faint nonaxisymmetric structure in NGC 1087 through the use of James Webb Space Telescope Near Infrared Camera, with an associated kinematic counterpart observed as an oval distortion in the stellar velocity map, H α , and CO J = 2 → 1 ...

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Dark Gaps and Resonances in Barred Galaxies
The Astrophysical JournalDark gaps, low surface brightness regions along the bar minor axis, are expected to form as a consequence of secular evolution in barred galaxies. Although several studies have proposed links between dark gap locations and dynamical resonances, the ...
