Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, Volume 111, Issue 9, Page 4235-4247, 1 September 2026.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Variations of Mid‐Magnetotail Magnetic Pressure During Substorms

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Magnetic reconnection is commonly observed in the mid‐tail plasma sheet during substorms, the mechanism behind this spatial preference, however, remains unsolved. This study focuses on magnetic pressure evolution within this critical region during substorms.

HF Heating Effects as Seen From Below and Above: First Results of Joint SURA–Ionosfera‐M Experiment

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract This paper presents the first results of a coordinated experiment on the ionospheric plasma response to high‐frequency (HF) overdense heating, conducted using the SURA heating facility and the Ionosfera‐M satellite. The experiment combined ground‐based observations with in situ satellite measurements, enabling a comprehensive study of ...
