Russian space tourist lineup

According to Personal SpaceFlight blog, several Russian space tourist candidates are getting their applications vetted by Roskosmos, and that Space Adventures (the group that handles these private space travelers) has two seats set aside on Soyuz flights in fall ’08 and spring of ’09. The names for who’s flying should be coming soon.

I always find it ironic that it’s the Russian space program that’s taking willing, paying passengers, while the US is not. Who would have believed that 20 years ago?

Shrimp-shell goop wound sealant to get test in outer space

Water Fish Wild 246784 LThis is wild, but apparently there is a would healant made out of shrimp shells that’s about to get space tested. Apparently they’re curious to see how chitosan, the biopolymer that makes up these space-age bandaids, acts in outer space. According to the New Scientist:

Chitosan is a water-soluble form of chitin, an abundant long-chain natural biopolymer that is a key component of the semi-transparent exoskeletons of arthropods from insects to lobsters, and in the cell walls of fungi.

Some researchers believe natural chitin helps protect arthropods from bacterial infection, important because they lack a conventional immune system. The soluble chitosan carries a positive charge that attracts the negatively charged membranes of bacteria, stopping them from multiplying and in some cases killing them. The charge also initiates clotting of red blood cells.
