How could we build a liveable space habitat?
In the not-too-distant future, humanity will be faced with the challenge of building permanent homes in space. For this to happen, space habitats will need to closely replicate Earth’s gravity, while dealing with the threat of radiation and meteorites from outer space. Through his research, Werner Grandl at Space Renaissance International in Italy considers how these challenges could be overcome. Through […]

Responses to spaceflight: The mouth as a mirror
During spaceflight astronauts experience extreme environmental conditions, such as cosmic radiation and the absence of gravity that impact their physiology. The resulting changes must be monitored. While blood is usually used to assess astronauts’ health, Professor Arthur Hand and Dr Maija Mednieks, from the University of Connecticut, suggest that saliva could be used as a non-invasive, easily collectible diagnostic fluid.
