Maternal Obesity and Childhood Cancer
Critically Speaking
In this episode, Therese Markow interviews Dr. Shaina Stacy about her studies on cancer risks in children depending upon the body mass index (BMI) of their mothers before and during pregnancy. Dr. Stacy explains how she obtained a sample of nearly 2 million mother-child pairs in the state of Pennsylvania, the largest sample size ever for such a study. They discuss how children of women with a BMI of over 30 when pregnant had a significantly higher risk of cancers compared to children of lean mothers. This was notable for leukemia in children under 5, especially acute lymphoblastic leukemia...

Dr. Cheryl Hawkes: Maternal Obesity Harms Fetal Brain Development
Critically Speaking
In this episode, Therese Markow and Dr. Cheryl Hawkes discuss the increasing scientific evidence that maternal obesity affects the developing fetal brain. While many of the effects manifest early, in infant temperament and childhood cognitive (IQ) decrements, other effects do not show up until years later, in adult psychiatric and neurodegenerative problems. The physical bases for these changes in fetal brains are also clearly evidenced in laboratory model systems, such as mice, where the maternal diets can be controlled, and the offspring not only can be given behavioral tests,...

Dr. Diane Tober: Egg Donation Can Exploit Donors
Critically Speaking
In this episode, Therese Markow and Dr. Diane Tober discuss the global egg donation industry, highlighting its lack of regulations and exploitative nature. Dr. Tober details some of her research on egg donors, revealing severe risks and some life-threatening complications that can affect 10-12% of donors. They discuss how donors are often uninformed about the risks and the pressures faced by donors to donate beyond current guidelines. With compensation varying wildly, there are often financial pressures that donors face, too. Finally, Dr. Tober advocates for standardized informed consent,...

Dr. Adam Berinsky: Political Rumors and Misinformation
Critically Speaking
In this episode, Therese Markow and Dr. Adam Berinsky discuss political rumors and misinformation. Dr. Berinsky defines rumors as unsubstantiated claims without evidence, emphasizing their social transmission. He identifies two factors influencing rumor belief: conspiratorial thinking and partisan polarization. Berinsky's research reveals that while some people firmly believe rumors, others are ambivalent and more open to correction. He suggests focusing on these undecided individuals rather than entrenched believers. Berinsky also highlights the role of political leaders in spreading...

Near Death Experiences
Critically Speaking
In this episode, Therese Markow and Dr. James Alcock discuss what near-death experiences are and the increase in them in recent years due to improvements in medical technology. While near-death experiences (NDEs) have been known about for a long time, we, as a scientific community, are starting to understand more about what they mean for neurological processes. However, despite knowing the science of what is happening, NDEs and how they are experienced are subject to one’s own beliefs, context, and even religious framework. Dr. Alcock and Therese also discuss the relationship between...

Dr. Deborah Lang: What is Skin Cancer?
Critically Speaking
In this episode, Therese Markow and Dr. Deborah Lang discuss the rise of skin cancer, particularly melanoma, and its causes. Dr. Lang explains that skin cancers are derived from different skin cells: basal cell carcinoma and squamous cell carcinoma, both linked to UV exposure, and melanoma, which can be UV-independent and linked to genetic susceptibility. Dr. Lang emphasizes the importance of early detection and personalized medicine, noting that melanoma can metastasize early. She also highlights the role of genetic mutations in cancer development and the impact of funding cuts on cancer...

Dr. Joshua Weitz: Asymptomatic COVID-19 Spreaders
Critically Speaking

Dr. Weitz criticizes early predictions of COVID-19's disappearance by mid-2020, attributing the error to underestimated infections and behavioral changes. He...
info_outlineIn this episode, Therese Markow and Natalie Wexler discuss the poor reading skills of American students, as evidenced by NAEP test results. Natalie highlights the ineffectiveness of current reading programs and the focus on skills over content. She also talks about the discrepancies between students of different backgrounds, and how The Matthew Effect appears in reading comprehension and general knowledge. She also encourages teachers and parents to introduce their children, as early as possible, to higher concepts and vocabulary as children can and do understand more than many give them credit for. Natalie also discusses the role of writing in enhancing reading comprehension and the need for systemic changes in education to improve literacy outcomes.
Key Takeaways:
-
When it comes to literacy and reading, the standards don’t specify content. Therefore, the tests are not grounded in consistent content.
-
Most kids need to learn their phonics in order to become fluent readers. Making this a more automated skill will free up brain power for comprehension.
-
Vocabulary is more likely to stick if it is heard in context and on repeat.
-
Read aloud to your kids. Kids can take in more sophisticated concepts and vocabulary through listening than reading. This goes through age 13.
-
More than average amounts of social studies in elementary school are correlated with higher than average reading scores later in school.
"Kids who started with less of that academic knowledge and vocabulary, if they don't acquire it through school, they're going to fall farther and farther behind, because they're going to be limited to those simple texts. Even if there's some new vocabulary, new information in those texts, they're less likely to be able to retain it because they don't have anything for it to stick to." — Natalie Wexler
