In this episode, Therese Markow and Dr. John Sweller discuss the decline in student preparedness for college and how the modern education system, which has shifted from knowledge acquisition to inquiry-based learning, is at the root of that decline. Dr. Sweller explains his Cognitive Load Theory, breaks down the differences between working memory and long-term memory, and why ineffective teaching methods continue to survive. Finally, they talk about the changemakers in education and how political and bureaucratic intervention can drive educational reform.

Key Takeaways:

• Education changed about 1-2 decades ago. The emphasis switched from the acquisition of knowledge to how to acquire knowledge itself. We need to emphasize the acquisition, not the discovery, of knowledge in education.

• Students who are subjected to inquiry-based educational approaches do substantially worse on international tests than students who are exposed to a knowledge-rich curriculum. The more emphasis your education system places on inquiry learning, the worse the students do.

• If you don’t show students how to do something and they don’t figure it out themselves, it cannot go into long-term memory.

• The best way to obtain information is to obtain it from somebody else. If you want to efficiently have somebody learn something, the best way to do it is to have somebody explicitly explain it.

"An educated person who can do things, think about things, solve problems, which otherwise they couldn't dream about solving, is somebody who's got enormous amounts of information in long-term memory, and that immediately tells us what education should be about. You need to have lots of information in long term memory, and an educated person is different from an uneducated person because of that and solely because of that." — Dr. John Sweller

In this episode, Therese Markow and Dr. Hussam Mahmoud discuss the vulnerability of bridges to climate change. When we think about climate-related disasters, hurricanes, floods, and wildfires come to mind. Probably the last thing we think about is a bridge collapsing, but we should. With over half a million bridges in the US, each with a life expectancy of 75 years, it is more important than ever to consider the role of climatic factors on bridge stability. Dr. Mahmoud discusses how flooding, extreme temperatures, erosion, and extreme heat are affecting the bridges and he emphasizes the need for proactive inspection and maintenance to mitigate these risks.

Key Takeaways:

• There are approximately 600,000 bridges across the US. Of the long-span bridges, there are about 6,000. Many of these bridges are old, some are in poor condition, and all are affected by climate change.

• Owing to the passenger and huge amount of industrial traffic crossing bridges, a collapse could cost trillions of dollars to the economy.

• Bridges are built for a life span of about 75 years, with proper maintenance and care. There was a bridge-building boom in the 1960s and earlier - and the majority were built over 50 years ago.

"Generally speaking, bridges are relatively very safe. Even if you lose an element or something that is carrying the load ends up breaking or cracking, bridges are phenomenal in being able to redistribute the load and figure out how to carry the load with the remaining elements." — Dr. Hussam Mahmoud

In this episode, Therese Markow and Dr. Ximena Lopez discuss the challenges faced by transgender youth, emphasizing the importance of gender-affirming care. Dr. Lopez explains the difference between sex and gender, noting that gender dysphoria is distress caused by a mismatch between one's gender identity and sex assigned at birth. She describes treatment options, including puberty suppression and hormone therapy, which can significantly improve mental health and reduce suicidality, particularly in teens. Dr. Lopez also criticizes state bans on gender-affirming care for minors and cites numerous studies showing its benefits, as well as discusses the inconsistencies in hormonal therapy for children and teens.

Key Takeaways:

• In medicine and psychology, gender and sex are two different things. While aligned in most people, they are not aligned in those individuals on the transgender, nonbinary, or intersex spectrum.

• Adults who transitioned later in life typically knew they were different when they were young, but didn’t have the language or awareness.

• When a child comes out as transgender, most parents are typically in denial. It is not until their child or teen is depressed and often suicidal, that the parents are willing to take the next steps with their child.

• Gender-affirming care at the beginning of puberty can help to pause the puberty of the incorrect gender where changes happen that cannot easily, if at all, be reversed later in life.

• Puberty suppression can be reversed on the off chance the individual changes their mind.

"Most of the stress comes from the adult world, and if the adults are transphobic and influence their kids to be transphobic, then we can also see kids who are transphobic, and then they can bully and discriminate. If it's a very affirming school where there are policies to protect transgender students, and the teachers and all the staff are on board, then that promotes well-being." — Dr. Ximena Lopez

In this episode, Therese Markow and Dr. Janine LaSalle discuss Dr. LaSalle’s research on autism, focusing on prenatal gene-environment interactions. She explains that autism affects one in 36 children and talks about how genetic and prenatal environmental factors, such as maternal health and chemical exposures, play a role in autism. Dr. LaSalle discusses how they use placental DNA to identify epigenetic marks linked to autism, aiming to predict probability of autism before birth in order to intervene early. The conversation highlights the importance of understanding these factors to develop early intervention strategies.

Key Takeaways:

• It's almost impossible to compare autism incidents across time because the diagnostic criteria have changed many times over this span. There's no definitive laboratory test for autism.

• A number of genes have been identified that increase the risk of autism, genes that affect prenatal neurodevelopment.

• Maternal obesity, maternal asthma or fever during pregnancy, and preterm birth are a few examples of maternal health factors implicated in autism. Environmental exposures during pregnancy that increase risk for autism include air pollution and some pesticide exposures - these have the best evidence because they can be measured easily.

• Prenatal identification of newborns at risk for autism allows treatment to begin immediately after birth to improve their developmental trajectories.

• While little boys have a much higher incidence of autism and ADHD, the mechanism underlying the sex difference is not understood.

"The best explanation for most cases of autism is really the combination of common environmental factors and common genetics." — Janine LaSalle, Ph.D.

In this episode, Therese Markow and psychologist Dr. Elizabeth Scott, discuss narcissism, its clinical definition and the characteristics of “malignant narcissism”. Dr. Scott explains that narcissism involves patterns of grandiosity, a need for constant admiration, a lack of empathy, high levels of manipulation, and the narcissist’s “kryptonite” - criticism. They view themselves as the victim, never at fault. Despite their arrogance, they are very insecure. Dr. Scott also discusses why treatment is challenging and why therapy often focuses on managing symptoms rather than the deeper core issues. They can’t see that they have a problem, and thus are resistant to treatment

Key Takeaways:

• The myth of Narcissus illustrates the danger of excessive self-focus, which is the hallmark of narcissism in clinical terms and is becoming increasingly common in some aspects of our modern society.

• Narcissists are very good at manipulation. They consciously will do things to sort of manage their image in the eyes of others. They may appear to show empathy at times in a relationship, but it's usually more of a means to an end than a genuine concern for the feelings of others.

• Criticism is like a kryptonite to a narcissist, so even the mildest critique can provoke a strong defensive reaction: anger, denial, or shifting the blame to somebody else.

• You cannot change a narcissist's behavior, but you can control your own responses to it. Think about limits and then give yourself leeway within those to protect your own mental health.

"[Narcissists] might mimic empathetic behaviors to achieve their own ends, but it's more about manipulation than genuine caring. So they can understand maybe what empathy looks like, but not really get how it feels and how it's supposed to feel and how those behaviors are supposed to be rooted in something inside them." — Elizabeth Scott, Ph.D.

Dr. Adam Schiavi is an assistant professor of anesthesiology and critical care medicine and neurology at the Johns Hopkins University School of Medicine. His areas of clinical expertise include anesthesiology, neurological critical care, disorders of consciousness and brain death diagnosis, clinical ethics, critical care medicine, and traumatic brain injury.

In this episode, Therese Markow and Dr. Adam Schiavi discuss how the definition of death has changed throughout history, what the current definition is, and how that is determined by the medical technology of the time. Brain death is the current definition of death, medically, but what happens to a body after brain death is determined can vary depending on the state you live in. This can be a trying time for families and for the providers involved with the now-deceased patient as the definition of death is not understood by everyone. They also discuss how brain death differs from other states of consciousness and how people often confuse the terminology of those different states, as well as the ability to hope for healing from all but brain death.

Key Takeaways:

• The total cessation of all functions of the brain is the current definition of brain death in the United States. This definition is based on a clinical exam testing all parts of the brain, typically done by somebody certified in doing brain death determinations.

• You have to have a reason for the neurologic exam to be declining. Without a reason, you can't call somebody brain dead.

• You can replace every organ in the body, but you cannot replace the brain and when the brain dies, the body dies all the time 100% unless those organ systems are artificially supportive.

"Our culture changes with technology and the way we define death is a part of culture. As that culture has shifted, the way we define death has also shifted with our new technologies of how we can actually determine whether people are dead." — Dr. Adam Schiavi

In this episode, Therese Markow and Dr. Katie Pelch discuss the harmful and pervasive effects of PFAS, also known as "forever chemicals." Found in various consumer and industrial products, contaminating air, water, and soil, they never break down. Dr. Pelch works for the Natural Resources Defence Council (NRDC) and has been studying PFAS throughout her career. Along with their many uses PFAS have been linked to serious health issues, including cancer and reduced vaccine effectiveness. The NRDC advocates for banning non-essential uses of PFAS and encourages public awareness and involvement in regulatory efforts. Dr. Pelch shares with us the prevalence of PFAS, its dangers, and the regulation or lack thereof.

Key Takeaways:

• When you heat the nonstick cookware above a certain temperature, some of the PFAS can migrate from the pan and into the food you’re going to eat, or they could enter the air that you breathe.

• Exposures from the air that we breathe and from our skin have generally been less well studied, but there is evidence to suggest that PFAS do enter our skin.

• Per the CDC, at least 98% of people in the United States have PFAS in their bodies.

• The EPA stepped up in a big way this year by finalizing the regulation of six PFAS in drinking water. This ban was preceded by many states proactively setting enforceable limits to PFAS in drinking water, some banning the unnecessary use of them entirely by 2032.

"Not only are PFAS persistent in the environment, but they're also persistent in our bodies, and in most cases, we don't have a great way to get PFAS out of our bodies. So the two most highly studied PFAS can last in our bodies for years." — Dr. Katie Pelch

In this episode, Therese Markow and Dr. Alex Hinton explore the potential for genocide in the U.S., highlighting historical and contemporary atrocities. Dr. Hinton emphasizes that genocide can target groups based on social constructs such as race, gender, and sexuality, among others. They discuss the rise of white supremacism and hate speech, and Dr. Hinton identifies risk factors such as political upheaval, economic instability, and armed militias. Dr.Hinton also stresses the importance of critical thinking and depolarization to prevent genocide, and suggests an easy way for everyone to do so without committing 40 hours per week to stay abreast of all of the issues and topics.

Key Takeaways:

• Genocide and mass violence are not typically planned from the beginning. They often evolve from other behaviors stemming from upheaval and past atrocities, scapegoating, grievance, and legitimation of formed hierarchies.

• Hate speech is everywhere—left, right, and center. Wherever someone is on the political spectrum, they can agree it's bad. The problem is that people sometimes disagree about what constitutes it.

• People are busy. Trying to keep informed can be a full-time job. One little thing everyone can do pretty easily to begin to do this in general, as we enter the political cycle, just pick a left-leaning, more centrist, and right-leaning news media source then on the top of the hour, turn on the TV, and flip between them and see the headlines.

"Ideology is central to all genocides, in some sense. Ideologies provide legitimation to disempower groups, and to legitimate different forms of hierarchy within a society and in the extreme. That then lays the basis for saying that groups are inferior." — Dr. Alex Hinton
