Life Confirmed At Extreme Depths

SEWilco writes "A few years ago the life forms around deep-ocean thermal vents were a surprise. Now ancient bacteria alive in rock 2 miles down have been found. The story is in the San Francisco Chronicle. It is also at Nature.Com, but that server is already rejecting connects. Other bacteria survived frozen in the pressures of an ocean 100 miles deep. This increases the known limits of where life can exist on any planet. Thomas Gold undoubtedly is not surprised at hot, deep bacteria living on hydrogen."

Pressure? So what?

Human beings seem to be hung on the idea that living in high pressure environments is an amazing thing simply because we can not do it.

Human life depends heavily on gaseous exchanges, which behave differently at different pressures. Since liquids and solids are hardly compressible, it seems like a no-brainer that organisms that do not rely on gaseous exchanges can reamin intact perfectly well in extremely high pressures.

I would have been more surprised if they had been destroyed.
