HowStuffWorks “The Body After Death”.

 

interesting excerpt: “The pancreas is full of so many bacteria that it essentially digests itself . As these organisms work their way to other organs, the body becomes discolored, first turning green, then purple, then black. If you can’t see the change, you’ll smell it soon enough, because the bacteria create an awful-smelling gas. In addition to smelling up the room, that gas will cause the body to bloat, the eyes to bulge out of their sockets and the tongue to swell and protrude. (In rare instances, this gas has created enough pressure after a few weeks to cause decomposing pregnant women to expel the fetus in a process known as coffin birth.)”

With a featured publication in the Aug. 7 issue of Science, Montana State University researchers have made a significant contribution to the understanding of a new field of DNA research, with the acronym CRISPR, that holds enormous promise for…

“Bacteria have evolved sophisticated immune systems to fend off viruses. We now have a precise molecular blueprint of a surveillance machine that is critical for viral defense,” Wiedenheft said.

I was first introduced to these microorganisms here: http://www.impactlab.net/2014/07/18/electric-life-forms-that-live-on-pure-energy-are-unlike-any-other-life-on-earth/. Not being sure whether this was speculative or entirely fictional, I Googled them.

I also found older articles published here: http://www.eurekalert.org/pub_releases/2009-12/uosc-nbb121509.php,  and here: http://www.pnnl.gov/science/highlights/highlight.asp?id=364.

In Shewanella oneidensis – Wikipedia, the free encyclopedia: “Shewanella oneidensis is a bacterium which can reduce poisonous heavy metal and can live in both environments with or without oxygen. Thisproteobacterium was first isolated from Lake Oneida, NY in 1988, which is where the name is derived from.[1] This species is also sometimes referred to as Shewanella oneidensis MR-1, indicating “metal reducing”, a special feature of this particular organism. Shewanella oneidensis is a facultative bacterium, capable of surviving and proliferating in both aerobic and anaerobic conditions. The special interest in S. oneidensis MR-1 revolves around its behavior in an anaerobic environment contaminated by heavy metals such as iron, lead; perhaps even uranium. Some experiments suggest it may reduce ionic mercury to elemental mercury.[2] Cellular respiration for these bacteria is not restricted to heavy metals though; the bacteria can also target sulfates, nitrates and chromates when grown anaerobically.”
