Well‐being decline during adolescence: school transition as a predominant driver beyond age progression

open access: yesJournal of Child Psychology and Psychiatry, Volume 67, Issue 9, Page 1513-1524, September 2026.
Background The transition from primary‐to‐secondary school significantly impacts students' well‐being. However, existing research provides limited insight into the long‐term impact of school transition on well‐being, and no studies have disentangled age‐related changes from transition‐specific effects.

Chain‐Length Regulation by WzzE Is Necessary for, but Genetically Separable From, Cyclic Enterobacterial Common Antigen Synthesis

open access: yesMolecular Microbiology, Volume 126, Issue 2, Page 190-207, August 2026.
Here, we demonstrate that polysaccharide chain length regulation plays a distinct role in enabling formation of a cyclic molecule important for the bacterial cell surface. However, this function is necessary, but not sufficient for the cyclic molecule's biosynthesis.

Slowly Rotating Traversable Wormholes Supported by Radially Varying String‐Fluid Matter: From Regular Geometries to Photon Trajectories

open access: yesAnnalen 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.
