Microgravity as a research area encompasses the systematic investigation of physical, chemical, and biological processes under conditions of greatly reduced effective gravitational acceleration, such as in orbiting spacecraft, drop towers, or parabolic flights. It enables isolation of gravity-driven phenomena, allowing precise study of fluid dynamics, combustion, phase transitions, material solidification, colloidal behavior, and fundamental physics, as well as physiological and cellular responses to altered mechanical loading. Microgravity research supports development of validated models for transport processes, structure formation, and mechanobiology, and informs the design of space systems, countermeasures for human health in spaceflight, and advanced materials and processes with potential terrestrial applications.
For astronauts in space, constipation is a well-known problem. But why this happens has long been unclear. Now, a new study from the University of Copenhagen in collaboration with NASA provides an idea of what happens in ...
