Haemodynamic responses to small muscle mass exercise before and after lung transplantation in end‐stage chronic obstructive pulmonary disease

Experimental Physiology, Volume 111, Issue 8, Page 3604-3619, 1 August 2026.
Abstract Cardiovascular control during exercise is impaired in chronic obstructive pulmonary disease (COPD). The central cardiopulmonary pathologies in COPD might drive the local muscle vascular abnormalities. We hypothesised that contracting muscle perfusion and O2 utilisation improve after lung transplantation (LTx) in COPD.

Local Variability of Ice Core Ammonium and Black Carbon Records From Tunu and Summit, Greenland: Implications for Long‐Term Biomass Burning Reconstructions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Paleoclimate reconstructions of wildfire using ice cores often rely on high‐resolution aerosol records of refractory black carbon (rBC) or ammonium (NH4+). The interpretation of such records, however, can be hindered by uncertainties related to long‐range atmospheric transport, spatial distribution and strength of emissions, as well as ...

First Report of Rising‐Tone EMIC Waves Driven by the Magnetosheath High‐Speed Jet

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Magnetosheath high‐speed jets (HSJs) are pervasive transient structures with enhanced dynamic pressure in the terrestrial magnetosheath and can exert notable local impacts on the magnetopause. Although various geoeffects have been reported to be associated with HSJs, whether HSJs can drive the generation of electromagnetic ion cyclotron (EMIC)

Controlling of the F Region Plasma Structures by the E Region Conductance in the Auroral Ionosphere

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract At high latitudes, the E and F regions of the ionosphere are strongly coupled through nearly vertical magnetic field lines. To simultaneously and directly relate the E and F regions' plasma structures, we ran a coordinated conjunction campaign between Swarm satellites and Incoherent Scatter Radar in Tromsø, Norway, during a moderate ...

Temporal Variations of Jupiter's Plasma Disk Observed by Juno

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In Jupiter's magnetosphere, a key question is how plasma is transported outward from its source near Io to the distant magnetotail. Since 2016, the plasma disk has been extensively observed by the Juno mission. Using plasma data from the JADE instrument, we perform an analysis revealing significant temporal variation. For different Juno orbits,

Latitudinal Discrepancy Between Thermospheric Density and Temperature Associated With Neutral Composition Effect

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In this study, multi‐source thermospheric observations and TIEGCM simulations were used to explore the latitudinal variations of thermospheric temperature and total mass density at equinoxes. At nighttime, temperature and density exhibit consistent latitudinal patterns, with higher values at high latitudes.
