It’s no secret that radiation is a great danger to astronauts. Most of the research to date concerns the effects of galactic cosmic rays, but what happens to those particles when they pass into a spacecraft?
A device currently being tested will reveal what kind of neutron energy spectrum astronauts are exposed to from neutrons inside a spacecraft, alerting the occupants when dangerous levels occur.
“When spacecraft travel through a variety of primary high-energy cosmic rays, large vehicles absorb those rays and convert them into neutrons,” said Dr. Richard Maurer, a researcher on the National Space Biomedical Research Institute’s (NSBRI) technology development team. “The spacecraft’s thick structure, in a sense, multiplies the primary particles so that there are more neutrons trapped inside a craft than the original number of cosmic rays that created them.”

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
