Summary

In episode ten of the 2019 R&D season, Just Science interviews Dr. Christopher Ehrhardt, professor at Virginia Commonwealth University, about a method for determining tissue type, age of evidence, and contributors from biological mixtures using cellular autofluorescence signatures. It goes without saying that cells collected from different parts of the body look different. Buccal, vaginal, epidermal, and blood cells all have unique intrinsic properties. However, when they are combined, it can be difficult to discern what components are actually in the mixture. Using Imaging Flow Cytometry, Dr. Ehrhardt has found a way to differentiate between cell types, estimate cellular age, and identify contributors in the sample. Listen in as he discusses how autofluorescence data and cellular properties are being used to analyze samples without destroying the evidence in this episode of Just Science. 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.
