ChromaBLOGraphy: This isn’t your average CSI, the International Network of Environmental Forensics (INEF)

Next week (June 10-12) at the Pennsylvania State University (PSU) the International Network of Environmental Forensics conference is being held.  This isn’t your typical crime scene investigation but, as defined by the INEF, “environmental forensics is the use of scientific techniques to identify the source, age, and timing of a contaminant into the environment.”  We [...]

ChromaBLOGraphy: Book Review: Echoes of Life: What Fossil Molecules Reveal about Earth History.

The year 1936 marks the beginning of organic geochemistry. It started with Alfred Treibs’ discovery of porphyrins in petroleum; compounds that closely resemble chlorophylls in plant matter. Another 25 years would pass before scientists recognized that these compounds, known as biomarkers, could reveal insights into the evolution of plants and animals spanning a time frame […]
