extremophiles cause news sensationalism… again


news that bacteria have been found incorporating arsenic into their genetic material and macromolecules is great.  it’s confirmed the possibility of alternate biochemistries that may not require all of the 6 elements we considered necessary (O, N, C, P, S, H, in no particular order).  however it’s a little too soon to be crying OMG ALIENS like most mainstream news sources love to do.

the best and most informed writeup i’ve seen is by far the one on Ars Technica.

the rest of the site is also quite worthy of checking out, if the content is of interest to you.
