Unique animal species can survive in space
Date:9/9/2008

Water bears (tardigrades) are the first animals in the world to have survived exposure to the vacuum and radiation of space. This has been established by Ingemar Jnsson, a researcher at Kristianstad University in Sweden.

It has been nearly a year since the ecologist Ingemar Jnsson had some 3,000 microscopic water bears sent up on a twelve-day space trip. The aim of the research project, which was supported by the European Space Agency, was to find out more about the basic physiology of tardigrades by seeing if they can survive in a space environment.

Now Ingemar Jnsson and his colleagues in Stockholm, Stuttgart, and Cologne are publishing their research findings, including an article in the international journal Current Biology.

"Our principal finding is that the space vacuum, which entails extreme dehydration, and cosmic radiation were not a problem for water bears. On the other hand, the ultraviolet radiation in space is harmful to water bears, although a few individual can even survive that," says Ingemar Jnsson.

The next challenge facing Ingemar Jnsson is to try to understand the mechanisms behind this exceptional tolerance in water bears. He suspects that even the water bears that got through the space trip without any trouble may in fact have incurred DNA damage, but that the animals managed to repair this damage.

"All knowledge involving the repair of genetic damage is central to the field of medicine," says Ingemar.

"One problem with radiation therapy in treating cancer today is that healthy cells are also harmed. If we can document and show that there are special molecules involved in DNA repair in multicellular animals like tardigrades, we might be able to further the development of radiation therapy."
