By far the largest of these communities resides in the gut, which is home to trillions of bacteria of hundreds or perhaps thousands of different species. Left unchecked, our gut bacteria begin to digest the intestines, and then the surrounding tissues, from the inside out, using the chemical cocktail that leaks out of damaged cells as a food source.

During this stage, your skin begins to change colors (ranging from green to gray to brown) and something called marbling happens.

As damaged blood cells continue to leak from disintegrating vessels, anaerobic convert haemoglobin molecules, which once carried oxygen around the body, into sulfhaemoglobin. We will do next-generation sequencing and bioinformatics to see which organ is best for estimating [time of death] thats still unclear, she says.
