Dr. John Kisiel: Early Cancer Detection Liquid Biopsy
Critically Speaking
In this episode, Therese Markow and Dr. John Kisiel discuss early cancer detection using liquid biopsies. Dr. Kisiel explains that liquid biopsies detect cancer signals in blood and urine, including tumor cells, fragments, proteins, and DNA. He highlights the FDA's approval of a blood test for colon cancer and the development of multi-cancer early detection tests. Dr. Kisiel notes that false positive and false negative rates vary by test. He emphasizes the potential of liquid biopsies to complement, not replace, standard screening methods and the need for further validation and clinical...

Dr. Stacy Andersen: Living to be a Hundred
Critically Speaking
Some people live more than a hundred years with no health problems and very little cognitive decline. How come? While healthy lifestyles certainly play a part in healthy aging, these “centenarians” share a number of special biological attributes. Furthermore, these attributes, along with attaining an age of 100 or greater, show a strong genetic component. Dr. Stacy Andersen of the Boston University School of Medicine has been studying these centenarians and the factors that are associated with not only their attaining an advanced age, but also doing so with no...

Dr. Kari Nadeau: Microplastics in Our Bodies
Critically Speaking
In this episode, Therese Markow and Dr. Kari Nadeau discuss the presence and health effects of microplastics in our bodies. Microplastics can enter our bodies through various environmental routes, including food, water, and air. They are in everyone’s bodies to some degree. Microplastics have been linked to health issues like stroke, cancer, and heart attacks. Simple actions like avoiding single-use plastics and processed foods can reduce microplastic levels in the blood by up to 80% in three months. Dr. Nadeau emphasizes the need for further research and consumer awareness to mitigate...

Dr. Lise Eliot: Brain Development, Sex, Gender
Critically Speaking
In this episode, Therese Markow and Dr. Lise Eliot discuss neurosexism and brain differences between males and females. Dr. Eliot explains that historical brain comparisons often aimed to prove women's inferiority, citing examples like weighing cadaver brains. Modern MRI studies show minor structural differences, but still present significant methodological challenges. She highlights that brain plasticity and social experiences shape gender differences, noting that women tend to have more active default mode networks, linked to anxiety and rumination. She emphasizes that gender is a...

info_outlineIn this episode, Therese Markow and Dr. Lise Eliot discuss neurosexism and brain differences between males and females. Dr. Eliot explains that historical brain comparisons often aimed to prove women's inferiority, citing examples like weighing cadaver brains. Modern MRI studies show minor structural differences, but still present significant methodological challenges. She highlights that brain plasticity and social experiences shape gender differences, noting that women tend to have more active default mode networks, linked to anxiety and rumination. She emphasizes that gender is a psychological phenomenon, not strictly binary, and that early life experiences significantly influence brain development.
Key Takeaways:
-
Sex is a biological phenomenon determined by physical characteristics and some secondary characteristics. Gender is a psychological phenomenon and is not binary - there are multiple dimensions of gender.
-
Without brain plasticity, you would be unable to learn anything. While the brain has more plasticity when you’re young, the brain can continue to learn and form new pathways even in adulthood.
-
Gender is a uniquely human attribute - other animals do not have gender. This is something that humans have invented and reinvented in every culture to adapt our different physical bodies and reproductive roles to a social environment.
"I'm really starting to think about gender learning as almost like learning a language. You learn the language, you learn the rules and the symbols of being a boy or being a girl until it's finally internalized, and you reach this moment of gender identity thanks to endless clues in your environment, and this strong drive to find your place and find your identity and social community." — Dr. Lise Eliot
