Tidal stresses may be causing constant icequakes on Saturn's sixth largest moon Enceladus, a world of interest in the search for life beyond Earth, according to a new study.

Researchers have used the latest wireless technology to develop a new radio receiver for astronomy. The receiver is capable of capturing radio waves at frequencies over a range several times wider than conventional ones, and can detect radio waves emitted by many types of molecules in space at once. This is expected to enable significant progresses in the study of the evolution of the Universe and the mechanisms of star and planet formation.

Researchers have found that nuclear factor E2-related factor 2, a master regulator of the oxidative stress response, affects muscle composition in microgravity. Targeting this protein could help protect against muscle changes during space flight, and could also have implications for muscle wasting in conditions such as cancer and aging.
