Pathogens in space

The research claiming that some bacteria become more virulent in space is just another example of over-hyped NASA astrobiology research; see the RRResearch post here: http://rrresearch.fieldofscience.com/2011/04/do-bacteria-become-superbugs-in-space.html.

For me, Siri is a useful resource, not just a novelty, because her voice recognition is more accurate than my typing.

Researchers think NASA is wrong

I've posted a long critique of the microbiology and molecular biology at http://rrresearch.blogspot.com.

Alex Bradley has provided the chemist's critique over at ScienceBlogs, at http://scienceblogs.com/webeasties/2010/12/guest_post_arsenate-based_dna.php.

We agree that the authors' conclusions and NASA's hype are unfounded.
