Adaptation of thoracic and lumbar curvature and spinal muscle activity under changing gravity
Frontiers in PhysiologyIntroductionThe effect of micro-gravity on the lumbar and in particular thoracic regions is poorly understood. The aim of this study was to evaluate spinal curvature across the lumbar and thoracic region, and extensor muscle activity during acute micro ...

Atmospheric Science Letters, Volume 27, Issue 10, October 2026.Deep atmospheric convection remains difficult to characterize due to its rapid vertical development and the challenging conditions for in situ observations. We present VARAND2, a 1D‐Var method exploiting short‐time‐lag passive microwave observations from a tandem of satellites to retrieve the vertical profile of ice water content and vertical air ...

Heat Transfer Enhancement in the Microscale: Optimization of Fluid Flow
Engineering Reports, Volume 8, Issue 10, October 2026.Microscale heat transfer deviates from conventional behavior due to scale effects and fluid properties. This review examines single‐phase convection and advanced working fluids, highlighting key mechanisms such as rarefaction, surface effects, and phase interactions, to guide optimized design of high‐performance microchannel heat exchangers.

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.Abstract Alternative stable state theory in aeolian geomorphology describes the occurrence of bare and vegetated aeolian dunes in response to long‐term climatic and ecological drivers. Transitions between states, as well as their co‐occurrence (bistability), can arise from perturbations to drivers, disturbance, and associated biophysical feedbacks ...

Acceleration inside an aircraft in parabolic flight
European Journal of PhysicsAbstract This paper aims to present and analyse the acceleration data inside an aircraft during a parabolic flight. The data used were obtained during the flight from the automatic recordings of the aircraft and from a portable data logger with a built-in 3-axis accelerometer connected to a graphic calculator.

Earth and Space Science, Volume 13, Issue 10, October 2026.Abstract Very Low Earth Orbit (VLEO) satellite platforms and quantum‐optical sensing technologies may provide new observation approaches for improving Earth's static gravity field models. This study conceptually assesses their potential contribution through a two‐tier closed‐loop simulation framework.
