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 ...

“Why can't they put us to sleep if we are suffering?”: La Nada and the desire for euthanasia among institutionalized older adults in Peru

Medical Anthropology Quarterly, EarlyView.
Abstract In this article, I examine how institutionalized older adults in Peru articulate suffering through the idiom of la nada—“nothingness”—and how this shapes desires for euthanasia. Moving from close ethnography of bodies in space and time to structural and ethical discourses on euthanasia, I argue that calls for euthanasia arise not only from ...

Utopia Remembers: The Soviet Past in the Imagined Communist Future

The Russian Review, EarlyView.
Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

Unveiling Lasting Impact: A Cultural‐Historical Activity Theory Perspective on Original Participants in an Afterschool STEM Club

School Science and Mathematics, EarlyView.
ABSTRACT The Girls Excelling in Math and Science (GEMS) club is a long‐standing afterschool STEM program (1994–present). The study investigates the features of GEMS by exploring retrospective experiences of a group of original GEMS girls (OGGs) who attended GEMS in 1994–1995. Survey data were collected from 14 OGGs and in‐depth interview data from nine

The current status and prospects of the impact of spaceflight on astronauts' cerebral neurological functions

Hangkong gongcheng jinzhan
The completion of the Chinese space station marks the successful realization of China's three-step development strategy for manned spaceflight. In the future，astronauts will routinely conduct spaceflights and remain in space for long-term stay to execute

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.

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.

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

Experimental Physiology, EarlyView.
Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.
