Using the Microbiome to Determine Time of Death (starts at 5:40): This week on How on Earth, we speak with Jessica Metcalf, an evolutionary biologist, who studies bacteria, specifically the microbiome. One of her research interests is using molecular biology to address basic hypotheses about the role of microbes in corpse decomposition. The time since death, or postmortem interval, also known as (PMI), is important for criminal investigations because it can lead to the identification of the deceased and validate alibis. PMI is critical to both forensic science and pop culture (e.g. TV shows Bones, CSI). Recently she co-authored a paper published in Science, describing how various species of the microbiome can be used to accurately and repeatedly determine the post-mortem interval.

What You Can Do About Global Warming (starts at 5:20): We interview Craig Hover, author of A World to Come Home To: Ending Global Warming in Our Lifetime. Craig is a licensed professional engineer with more than 30 years of engineering, project and facilities management, financial services and consulting. In his book he lays out a comprehensive vision of implementing sustainable strategies for reducing carbon emissions and reversing the current trends in climate change.
Pluto Flyby (start time 1:00): Joel Parker discusses the New Horizons mission from the command center live!
An educator and perfomer, Len Barron first developed a piece about Einsteina and Bohr as a one man show, but then decided to evolve the project by enlist the help of 8 grandmothers to tell the story with their own added pizazz. Not only was lively performance produced, but a process and experience was shared. This process was captured by documentary film maker Robin Truesdale in a film coming to the Dairy Center this weekend entitled A Beautiful Equation. Both Robin and Len have joined us today in the studio to tell us more about the film, the process, the scientists and the grandmothers.
