Green Slime

A week or two ago, I came across this lump of green jelly-like substance in the Wilderness.  It was on a dead leaf on the ground just below this slime-covered log:

I suspect that this slime is blue-green algae (Cyanobacteria), possibly a  Nostoc sp.  In particular, it looks like the amorphous terrestrial form shown at the foot of this page at Down Garden Services.

Microbiologist brings NASA down to Earth

... NASA's shameful analysis of the alleged bacteria in the Mars meteorite made me very suspicious of their microbiology, an attitude that's only strengthened by my reading of this paper.  Basically, it don't present ANY convincing evidence that arsenic has been incorporated into DNA (or any other biological molecule). ...

... If this data was presented by a PhD student at their committee meeting, I'd send them back to the bench to do more cleanup and controls. ...
