At the beginning of the 1900s, New York City was in turmoil. Prohibition loomed, outbreaks of typhoid and an influenza pandemic had people on edge, and the city was steeped in corruption. One of the many consequences of that corruption was a completely inept coroners office. Instead of having trained medical examiners work out the causes of sudden and suspicious deaths, New York City coroners were politically appointed. And they didn't have the slightest idea of how to do a thorough autopsy. They were sign painters and milkmen and funeral home operators and people who had done favors for the party. They bungled the cause of death so consistently and so dramatically that the police and the district attorney's office told coroners to stay away from their crime scenes. This was a horrific situation, unless you were a poisoner. In January, 1915, New York City's government released a report saying that murderers were easily escaping justice and that “skillful poisoning can be carried on almost with impunity.”In this episode of Tiny Matters, Sam and Deboki chat with Pulitzer Prize-winning journalist Deborah Blum, the author of The Poisoner's Handbook, about the rise of forensic toxicology in the United States. Listeners will be taken on a journey through some of the disturbing poisoning cases of the time that helped lay the groundwork for the field — with a focus on arsenic, radium and cyanide — and the pivot role medical examiner Charles Norris and chemist Alexander Gettler played in restoring public safety and finally stopping poisoners in their tracks.

The Local Lens is a public health podcast going inside one community's experience with the drug epidemic. Everyone in the town of Stanton, KY sees this drug issue differently from each other, either because of their personal lives or professional roles. This show aims to showcase those different perspectives by having honest, in-depth interviews.There is a chase happening in the world of chemistry. The list of drugs and chemicals being abused is growing so fast that no one can truly keep up. We are all aware of fentanyl at this point, but what most people do not realize is that fentanyl is an umbrella-term for a whole category of drugs. The terrifying fact is this: most people are unaware of the chemical mixtures out there. If someone thinks they are taking a Xanax pill, it could very easily be a counterfeit pill made with 5 different kinds of fentanyl. It is nearly impossible for anyone to know exactly what drugs and chemicals they are buying or selling. One place that can tell what is in a drug is the Kentucky State Police's forensic lab. On this episode, chemist Rebecca Stone tells us about the changing drug landscape from a chemical perspective. This science-heavy episode is not meant to bring a level of understanding, but just a basic awareness of what is out there. These are our people, using our voices, telling our stories, because no one sees it like we do.24-Hour Crisis Line: 1-800-562 8909Visit findhelpnowky.org to find treatment options for you in Kentucky.Need help now?

In episode one of our Strengthening the Forensic Workforce season, Just Science sat down with Dr. José Almirall, a Distinguished University Professor in the Department of Chemistry and Biochemistry and Director of the National Science Foundation-funded Center for Advanced Research in Forensic Science at Florida International University, and Dr. Sarah Kerrigan, Professor and Chair of the Forensic Science Department at Sam Houston State University and Director of the Institute for Forensic Research, Training and Innovation, to discuss the inception of the Forensic Science Education Programs Accreditation Commission (FEPAC) and chemistry programs in forensic science. Built on the foundation of the Technical Working Group on Education and Training in Forensic Science, or TWGED, FEPAC became an official standing committee of the American Academy of Forensic Sciences and awarded its first accreditation in February 2004. Since then, over 50 undergraduate and master's level forensic science programs have been accredited in the United States. Listen along as Dr. Almirall and Dr. Kerrigan discuss their roles as founding members and early adopters of FEPAC, training the next generation of forensic chemists, and the importance of expanding the number of forensic science Ph.D. programs. This episode is funded by the National Institute of Justice's Forensic Technology Center of Excellence.
Dr. Theresa Stotesbury, Forensic Chemist from Ontario Tech University has been studying different aspects of blood such as time of deposition from DNA degradation, extreme temperature effects, blood substitutes, animal blood and much more!Originally aired on April 15, 2021
In this Episode I sit down again and talk with Dr. Lauryn DeGreeff. She has complete more research since the last time we talked to her and has focused on odor mixtures. We talk about mixture vs cocktail and debunk a few myths that exist in the K9 world. In my intro I cover the topic of FALSE ALERTS and what a 3 main causes and some ideas on how to fix them. PHD, Forensic Chemistry, Florida International University Dr. Lauryn E. DeGreeff has worked in the field of analytical chemistry in support of canine detection for more than 12 years. She received a Ph.D. in Chemistry with an emphasis in Forensic Science from Florida International University in 2010. Her research focused on the sampling, characterization, and delivery of human odor, living and deceased, for the purpose of canine detection. Following the completion of her doctorate, she worked as a research fellow at the Federal Bureau of Investigation, Counterterrorism and Forensic Science Research Unit. Her research focus was detection and determination of human scent and odor and human blood or the development / improvement of canine training aids and training methods. Dr. DeGreeff began her research at the U.S. Naval Research Laboratory in 2012 with research efforts focused on the characterization of explosives for instrumental and canine detection. She has since developed and patented a canine training tool for training on mixed odors, which has recently been brought to commercial market. Additional research has included a chemistry-based approach to studying canine olfaction for the purpose of improving canine training and informing field vapor sampling practices. Dr. DeGreeff has published numerous journal articles, holds three patents, has presented her research at numerous national and international conferences, and frequently gives educational seminars law enforcement officers and military personnel.

William Shirley, 10 out of 10 on the Armineh Davis Kindness Scale, left us a year ago in a pandemic to pursue his dreams in the very cold state of Michigan. Having been entirely isolated in his apartment for the year, William could not wait to catch up with his TTC family.This stuff also happens: Some of the TTC Teens made their #TTCDivaDads return to breakdown Spacegirl the Musical, coming soon. Rodney and Dana recorded TOGETHER, which meant Dana was lucky enough to try Rod’s newest cocktail…. Or was he? Cynthia performer her now iconic Mike Kilgore impression, and we all learned the importance of always saving the last one for Andy. DRINK RECIPE: To a cocktail shaker, add:2 oz white rum0.5 oz gunpowder green tea simple syrup*0.4 oz fresh lime juice0.4 oz fresh lemon juice4 drops black lemon bitters or daiquiri bitters4 drops sea salt saline solutionShake with ice. You want quite a bit of dilution from your ice, so either shake with wet ice or with some crushed ice in with your larger ice. You could also add 1/3 oz of ice-cold water to your shaker if you do not have wet ice or crushed ice available, or if you simply want more dilution to your daiquiri. Double-strain into a chilled glass. You want to double-strain in order to avoid getting small ice chips in your drink.Support TTC by going to ibelieveinTTC.comLINKS: https://www.ttcdivadads.com/ https://www.facebook.com/TTCDivaDads https://www.instagram.com/TTCDivaDads/https://www.youtube.com/channel/UCYD2...https://twitter.com/TTCDivaDadshttps://www.tiktok.com/@ttcdivadadsBio:William is originally from Austin, Texas.

If you thought a career in science means spending your best years in a dark laboratory for long, boring hours doing routine experiments, think again! Dr. Cora Young, from York University in Toronto, does a significant part of her environmental chemistry work in the field. From measuring air quality in residential and business spaces, to going high altitude on airplanes, or doing measurements in forests and even in the Arctic. In this episode, we discuss research in the growing field of environmental chemistry, how it differs from traditional analytical chemistry, and what it means bringing high precision analysis out of controlled laboratory environments. Dr. Young sheds light on how analyzing air quality can have a profound impact on international regulations and quality of life. From understanding emissions of worrisome pollutants such as polyfluoroalkyl substances (PFAS), to how cooking at home can affect our health, this is a fascinating discovery of the chemistry of air.
Episode 35: A conversation with Dr. Darren Williams of Sam Houston State University about cleaning processes and materials. Dr. Williams has been at SHSU since 2004 teaching Physical Chemistry, Forensic Chemistry, and graduate courses in Spectroscopy and Thermodynamics. He came to Huntsville from the US-DOE Pantex Plant in Amarillo. He taught at West Texas A&M University for four years after obtaining his Ph.D. from Oregon State University in 1997. He is originally from Fort Worth, and obtained his B.S. in chemistry from the University of Texas at Austin in 1992. He is the author of over two dozen research articles and book chapters covering a broad range of topics, such as cleaning process changes to reduce environmental impacts, contact angle methods for cleanliness verification, prediction of the spectroscopy of aged explosives, and chemical education improvements in Physical Chemistry. Dr. Williams leads the Cleaning Research Group at Sam Houston State University that studies all aspects of finishing and cleaning of high-value and mission-critical parts in the aerospace, medical, electronics, and manufacturing sectors. His lab has dry vapor spray, ultrasonic, vapor degreasing, and vacuum cycle cavitation cleaning equipment. The CRG formulates and tests azeotropic solvent blends, and measures flashpoint, viscosity, surface tension, and specific gravity. Much of the research is performed and published openly, but the CRG also performs contracted work under non-disclosure for external clients. Dr. Williams created the Product Quality Cleaning Workshop in 2018 to address the growing need for education on cleaning processes in industry. The next workshop is May 13-14th, 2020 at Sam Houston State University in Huntsville, TX. Registration is now open at https://tinyurl.com/wcnjjw5
On this episode we will focus on the factual side of mysteries. First we interview Rich Cohen and discuss his latest historical true crime. THE LAST PIRATE OF NEW YORK A GHOST SHIP, A KILLER AND THE BIRTH OF A GANGSTER NATION. The true account of Albert Hicks rise to become the man gangsters told stories about. He was the last man hung for piracy in New York.Next we interview Anita Zannin. She graduated Magna Cum Laude from Buffalo State College with a Bachelor of Science degree in Forensic Chemistry and a second Bachelor of Science degree in Criminal Justice. She received a Master of Science degree in Forensic Science from Syracuse University. Additionally, she taught for 4 years for Syracuse University's Forensic and National Security Sciences Institute and has been named a Visiting Professor at Francisco Marroquin Law School in Guatemala. Additionally she served as the faculty advisor to Syracuse University’s Forensic and National Security Sciences Institute’s Graduate Student Organization; Forensic Science: Code Orange (FSCO). Prior to entering the Forensics field, Ms. Zannin worked and studied in the medical field for many years. We discuss her role in crime solving and whether fiction gets it right.
In June 2019 Gudrun talked with Serena Carelli. Serena is member of the Research Training Group (RTG) Simet, which is based in Karlsruhe, Ulm and Offenburg. It started its work in 2017 and Gudrun is associated postdoc therein. The aim of that graduate school is to work on the better understanding of Lithium-ion batteries. For that it covers all scales, namley from micro (particles), meso (electrodes as pairs) to macro (cell) and involves scientists from chemistry, chemical engineering, material sciences, electro engineering, physics and mathematics. The group covers the experimental side as well as modeling and computer simulations. Serena is one of the PhD-students of the program. She is based in Offenburg in the group of Wolfgang Bessler (the deputy speaker of the RTG). Her research focusses on End-of-life prediction of a lithium-ion battery cell by studying the mechanistic ageing models of the graphite electrode among other things. Mathematical modelling and numerical simulation have become standard techniques in Li-ion battery research and development, with the purpose of studying the issues of batteries, including performance and ageing, and consequently increasing the model-based predictability of life expectancy. Serena and others work on an electrochemical model of a graphite-based lithium-ion cell that includes combined ageing mechanisms: Electrochemical formation of the solid electrolyte interphase (SEI) at the anode, breaking of the SEI due to mechanical stress from volume changes of the graphite particles, causing accelerated SEI growth, gas formation and dry-out of the electrodes, percolation theory for describing the loss of contact of graphite particles to the liquid electrolyte, formation of reversible and irreversible Li plating. The electrochemistry is coupled to a multi-scale heat and mass transport model based on a pseudo-3D approach. A time-upscaling methodology is developed that allows to simulate large time spans (thousands of operating hours). The combined modeling and simulation framework is able to predict calendaric and cyclic ageing up to the end of life of the battery cells. The results show a qualitative agreement with ageing behavior known from experimental literature. Serena has a Bachelor in Chemistry and a Master's in Forensic Chemistry from the University of Torino. She worked in Spain, the Politécnico de Torino and in Greece (there she was Marie Curie fellow at the Foundation for Research and Technology - Hellas) before she decided to spend time in Australia and India.

Narcan and Synthetic Opioids: vive la résistance? Probably not. Read this absolutely brilliant piece from The Tox & The Hound here. (They did all the hard work and we stole their sources.) Opioid "resistance" to naloxone is most likely not a thing, per se. The reported effect from synthetic and novel opioids are unlikely to be due to the agent's binding affinity for receptors within the brain, but rather from an ability to rapidly permeate the blood brain barrier much faster than "traditional" opioids such as heroin. Even in cases where a synthetic opioid agent was identified, the vast majority of cases did not need more than 4mg of naloxone to achieve reversal. Synthetic opioids don't bind any more "tightly" to receptors than naloxone. Synthetic opioids will usually cross the blood brain barrier faster than traditionally encountered agents. Most available evidence shows that synthetic opioid toxicity does not require significantly more naloxone to achieve clinically significant effect. Ergo, the traditional serial naloxone dosing algorithm does not need much modification. 0.04mg -> 0.4mg -> 2mg -> 4mg -> 8mg -> 10mg Not all that "overdoses" is an opioid. Consider all other causes of altered mental status or coma. Namely: hypothermia, hypoxia, and hypercarbia. Acidosis may potentiate the effect of opioids, highlighting the demand for timely and effective ventilation. Polypharmacy or adulteration is increasingly common. Consider intoxication by additional agents. Anchoring bias is a dangerous phenomenon: don't get burned! The Nose Knows. Or does it? Intranasal (IN) naloxone is popular among many EMS agencies as well as law enforcement, fire departments, and bystanders. IN naloxone has been shown to be effective in several randomized controlled trials for successful reversal of opioid intoxication. However... There are important pitfalls to be cognizant of when choosing this option for delivering naloxone. Intranasal naloxone has poor bioavailability when compared to IV or IM dosing, so higher doses may be required to achieve clinical effect. This is further potentiated by the maximum volume able to be absorbed by the nasal mucosa (around 0.5mL). Patients administered intranasal naloxone may have a variable or delayed response in achieving reversal. Protect Ya Neck Standard isolation precautions are adequate protection against the overwhelming majority of overdose scenes. In the rare instance where respiratory or splash exposure is a concern, a properly fitted N95 mask and goggles will be sufficient. To date, there has yet to be a laboratory confirmed case where a first responder or emergency healthcare provider has suffered a clinically significant opioid intoxication (bradypnea, hypoxia ) as the result of an occupational exposure to fentanyl or its analogues.
