Summary

In episode one of our Case Studies Part 1 mini season, Just Science sat down with Michael Fagert, a certified latent print examiner at the Kansas Bureau of Investigation, to discuss a latent print phenomenon that is not often seen in casework. There are very few instances of identifiable fingerprints on cartridge cases recovered from crime scenes as the firing process introduces adverse physical and thermal stressors to fingerprint residues. Several processing methodologies have been investigated for the development of latent prints on spent ammunition, like gun blue solutions, but only a few studies reported success on casework samples. Listen in as Michael discusses his published case report on how an untreated latent print encountered on a cartridge case was subsequently identified to the suspect in the case. This episode is funded by the National Institute of Justice’s Forensic Technology Center of Excellence (Award 15PNIJ-21-GK-02192-MUMU).

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.
