I trust that artist Rhim Lee is a visionary and all around great person, but I was a bit surprised when her TED talk had almost 1.5 million views. She is a talented speaker, funny and full of energy; her “Great Idea Worth Spreading” is a “mushroom suit” that would help nature extract our… ....
Abstract Traditionally, the post-mortem interval (PMI) is determined using methods such as forensic entomology or forensic pathology, however, these techniques are often limited to a particular post-mortem window of up to 72 – 120 h after death. In this study, lipids extracted from decomposing human tissue were investigated as potential soft-tissue biomarkers of PMI. Tissue samples were collected from two whole human donors (n = 2), one frozen and one fresh, placed at the Australian Facility for Taphonomic Experimental Research (AFTER) over the course of 69 days post-placement. These samples were analysed using gas chromatography coupled with tandem mass spectrometry (GC–MS/MS), demonstrating statistically significant differences for most fatty acid analytes and further highlighting the well-known stability of sterol compounds over time. Differences were observed between the fresh and frozen donor, with the fresh donor displaying more distinct stages of decomposition. Chem ....
