Media ion composition controls regulatory and virulence response of Salmonella in spaceflight. [PDF]

PLoS ONE, 2008
The spaceflight environment is relevant to conditions encountered by pathogens during the course of infection and induces novel changes in microbial pathogenesis not observed using conventional methods. It is unclear how microbial cells sense spaceflight-

Spirituality and Spaceflight

Crossings: An Undergraduate Arts Journal, 2023
While the advent of space flight is relatively new, humankind has always had a fascination with the heavens. Ancient religions across numerous civilizations had spiritual and/or religious beliefs as to what lay in the heavens, or what is now referred to as outer space.

Incremental Shifts, Strategic Orbits: The Evolution of EU Space Policy Through Gradual Security Linkages

Global Policy, EarlyView.
ABSTRACT This article examines the evolution of European Union (EU) space policy through the lens of historical institutionalism, highlighting how security and defence considerations have been incrementally integrated into a domain originally framed as civilian and scientific.

The cerebral palsy directed acyclic graph: A structural causal model of aetiology

Developmental Medicine &Child Neurology, EarlyView.
The first international cerebral palsy directed acyclic graph (CP‐DAG) maps over 100 nodes and 370 links across biological, clinical, and social domains, offering a unified causal framework to guide research and identify knowledge gaps. Abstract Aim To describe the development of the initial version of the cerebral palsy (CP) directed acyclic graph ...

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 ...

Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest

Experimental Physiology, EarlyView.
Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.

The effectiveness of RNAi in Caenorhabditis elegans is maintained during spaceflight.

PLoS ONE, 2011
BackgroundOvercoming spaceflight-induced (patho)physiologic adaptations is a major challenge preventing long-term deep space exploration. RNA interference (RNAi) has emerged as a promising therapeutic for combating diseases on Earth; however the efficacy
