Computers in Our Cosmos: Intersections in Geographies of Care, Abolition Geographies and Worker Movements

Transactions of the Institute of British Geographers, EarlyView.
ABSTRACT AI assistants on spacecrafts. Netflix streamed through inter‐planetary communication networks. Colonies on Mars by 2050. While the glamorous public–private ventures into outer space curate discussions on the technical specificities of these proposed projects, this paper reorients discussions on such developments through critical frameworks of ...

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

Experimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.

The Link between Galaxy Structure Properties and Star Formation in Local Galaxies

The Astrophysical Journal
To investigate the role of morphology in galaxy evolution, we analyze the relationships between galaxy structure, star formation, and H i gas content.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

The Quest for a Stable Disk

The Astrophysical Journal
The majority of disk galaxies manifest spirals and/or bars that are believed to result from dynamical instabilities. However, some galaxies have featureless disks, which are therefore inferred to be dynamically stable.
