Gut Microbes Take Over Your Body When You Die

You have around 100 trillion bacteria living in your gut — and that’s a good thing. Known as gut flora or the gut microbiome, these microorganisms help your body digest certain foods, aid the immune system, and maintain a healthy gastrointestinal tract, all in exchange for a constant food supply.
But when you die, your friendly gut flora quickly become your gut foe. Without food, the microbes escape your GI tract through the circulatory system and spread to your other organs, feeding on your dying cells and colonizing your body.
Now, forensic experts are finding that this macabre Manifest Destiny may provide crucial clues about a corpse. According to New Scientist, Peter Noble and his research team at Alabama State University analyzed organ tissue samples from 11 cadavers, between one to 10 days after death. From the spreading bacteria’s genetic material, they were able to figure out how long it took for the gut microbes to reach other organs, and which species traveled where.
Apparently, there wasn’t much rhyme or reason to this microbial takeover:
Contrary to the team’s expectations, there was no predictable pattern of microbe distribution. This was a surprise, says Noble, as he had expected different microbes to thrive in different organs. For example, the team had thought that bile-tolerant species would flourish in the liver, whereas those adapted to iron-rich environments would do better in the spleen.
In fact, there was more variation between individuals and according to time since death than there was between the organs within a single cadaver (Journal of Microbiological Methods, doi.org/t6x).

However, these findings do hold some benefit, especially in the field of forensics. Knowing how gut bacteria swarm throughout the body post mortem can reveal a body’s time of death or where the body has been lying, as the environment surrounding the body at death can have a significant effect on the spread of gut microbes. If a body has been moved to a second location after death, the bacteria of the internal organs can indicate where the person was originally killed. So, after you die, your gut microbiome is still working for you.

Just a friendly reminder that you are extremely powerful, you can literally do anything you want. Quit your job? Ask your crush out? Work on your craft? Kill a mafia boss? Eat a pistachio flavoured hotdog? Burn down your house and skinny dip in your neighbors pool? Choke out your old highschool teacher? SO MANY CHOICES, AND YOU CAN PICK ANY OF THEM

We can’t stop staring at these breathtakingly dramatic wire sculptures by Staffordshire, England-based sculptor Robin Wight. He specializes in transforming lengths of stainless steel wire into beautiful fairies who appear to be exulting in power of the wind as it scatters the seeds of giant dandelions they hold or trees and blades of grass to which they cling.

Visit Robin Wight’s website and Facebook page to view more of his wonderful wire fairies and click here to learn about Wight’s painstaking process for creating these fantastic pieces. He even offers DIY Fairy Sculpture Starter Kits so you can make your own.
