Journal of the Royal Anthropological Institute, EarlyView.Space activities in subarctic Sweden are predicated on older infrastructures of underground resource extraction. The ongoing expansion of the country's rocket launch site outside Kiruna relies on the Swedish state's historical construction of the region as a resource frontier.

Regolith behavior under asteroid-level gravity conditions: low-velocity impact experiments
, 2018 The dusty regolith covering the surfaces of asteroids and planetary satellites differs in size, shape, and composition from terrestrial soil particles and is subject to very different environmental conditions.

Forces on a boiling bubble in a developing boundary layer, in microgravity with g-jitter and in terrestrial conditions [PDF]
, 2012 Terrestrial and microgravity flow boiling experiments were carried out with the same test rig, comprising a locally heated artificial cavity in the center of a channel near the frontal edge of an intrusive glass bubble generator.

The Role of Nitric Oxide in Skeletal Simulated Microgravity Response [PDF]
, 2015 Prolonged exposure to the space environment leads to bone loss. Using a ground-based model for microgravity (hind-limb unloading), it has been shown in rodents that proliferation and differentiation activity of osteoprogenitors are decreased with ...

British Journal of Clinical Pharmacology, EarlyView.Abstract Aims Therapeutic drug monitoring for astronauts faces limitations in conventional blood sampling and sample management onboard the international space station. Here, we explore the feasibility of dried blood spot (DBS) collection during parabolic flights (PF) to overcome these constraints.

Marangoni, Mills and Microgravity
High Temperature Materials and Processes, 2003 Surface tension is the common denominator for all three M's of the title. Its spatial variation is responsible for surface tension driven Marangoni convection. Of equal importance for the surface tension of liquid metals is the role of surface active elements, a topic which has occupied a major portion in the professional career of Prof.

Changes to human sleep architecture during long‐duration spaceflight
Journal of Sleep Research, EarlyView.Summary Both rapid eye movement and non‐rapid eye movement sleep are important for cognitive function and well‐being, yet few studies have examined whether human sleep architecture is affected by long‐duration spaceflight. We recorded 256 nights of sleep from five crew members before (n = 112 nights), during (n = 83 nights) and after (n = 61 nights) ~6‐
