Microgravity and the respiratory system [PDF]
European Respiratory Journal, 2014 The structure of the lung, with its delicate network of airspaces and capillaries, means that gravity has a profound influence on its function. Studies of lung function in the absence of gravity provide valuable insight into how, for we Earth-bound individuals, its unavoidable effects shape our lung function.

The futuristic manifolds of REM sleep
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Since one of its first descriptions 70 years ago, rapid eye movement sleep has continually inspired and excited new generations of sleep researchers. Despite significant advancements in understanding its neurocircuitry, underlying mechanisms and microstates, many questions regarding its function, especially beyond the early neurodevelopment ...

Is sleep affected after microgravity and hypergravity exposure? A pilot study
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Sleep is known to be affected in space travel and in residents of the international space station. But little is known about the direct effects of gravity changes on sleep, if other factors, such as sleep conditions, are kept constant. Here, as a first exploration, we investigated sleep before and after exposure to short bouts of microgravity ...

Experimental Physiology, EarlyView.Abstract Muscle disuse leads to muscle atrophy and a decrease in muscle function that is primarily driven by reduced muscle protein synthesis (MPS). The aim of this systematic review and meta‐analysis was to examine the effect of different models of muscle disuse on rates of MPS.

Gas–Solid Phase Separation of Active Brownian Particles Under Confinement of Hard Walls
NanomaterialsBy means of computer simulations, we have investigated the gas–solid phase separation of active Brownian particles (ABPs) under the confinement of two hard walls, distinct from the gas–liquid phase separation typically seen in bulk systems.

The effects of bed rest on cardiometabolic health: A systematic review and meta‐analysis
Experimental Physiology, EarlyView.Abstract Horizontal bed rest (HBR) and head‐down tilt (HDT) are models of physical inactivity. In this systematic review and meta‐analysis, we aimed to quantify changes in cardiometabolic outcomes during HBR and HDT in healthy adults. Following the PRISMA guidelines, we searched PubMed, Scopus, Web of Science and Cochrane Library until 1 October 2025 ...
