Summary

In episode three of the 2019 R&D season, Just Science interviews Dr. Robert Allen, professor and head of the Forensic Sciences Department at Oklahoma State University, about a method to estimate the age of bloodstains using quantitative PCR. Traditionally, RNA has been used to identify types of cells and to determine if a sample of blood came from two sources. Dr. Allen and his team have found a new use for the single-strand genetic material – estimating the age of dried blood. By studying the ratios of degradation that take place in RNA, they can estimate the age of a blood stain up to three years old. Listen along as our guest discusses his research and RNA’s role in body fluid identification. This season is funded by the National Institute of Justice’s Forensic Technology Center of Excellence.

intuitions behind Data Science Ashay Javadekar No math, no equations, just intuitions behind Data Science. Safety Frontiers Podcast Cristian Sylvestre / David Pope Much of what is “new” in safety has not been proven to make any difference to safety performance, some of it possibly making it worse. Our aim is to use legitimate science to explore ways to help improve safety and move beyond just fixing the environment or improving the system or making safety more conscious.These three approaches helped us improve safety and brought us to where we are today, but they are struggling to help us improve further.In the Safety Frontiers Podcast, our focus is to explore novel ways of thinking about safety: using different approaches to make systems more effective, strengthen safety culture, and take a deep dive into the discoveries and insights gained from neurobiology and brain research over the last 5 years. This will be new information to many. We know disruptive thinking challenges long-held beliefs and accepted norms. As such, it could be confronting for some. However, significant improvements tend to come from new perspectives and that is what we are StoryCraft Ben Hart A show about the art and science of storytelling.
