Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 9, Page 2284-2302, September 2026.
Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

Which attributes of restored oyster reefs provide the best habitat for sportfish?

open access: yesRestoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Restoration practitioners seek to restore oyster ecosystems as habitat designed for species targeted by recreational fisheries, but they require information on which specific habitat parameters of oyster reefs are preferred by fish.

Greater muscle mass does not affect peripheral hypercapnic chemosensitivity during exercise in healthy adults

open access: yesPhysiological Reports, Volume 14, Issue 17, September 2026.
Abstract Peripheral hypercapnic chemosensitivity (PHC) is the ventilatory response to a brief rise in arterial carbon dioxide tension. PHC is known to increase at the onset of exercise, with no further increases with progressive exercise intensity. The mechanisms for this augmentation remain unclear but may involve central command.

Internal Structure and Formation Process of a Giant East Antarctic Grounding‐Zone Wedge

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The marine‐based portions of the East Antarctic Ice Sheet are currently losing mass at an accelerating rate due to atmospheric and oceanic forcing. Assessing these changes requires understanding long‐term grounding‐zone dynamics preserved in glacial geomorphology, including understudied East Antarctic shelf sectors.
