Rank #1: Your brain hallucinates your conscious reality | Anil Seth

Podcast cover
Read more
Right now, billions of neurons in your brain are working together to generate a conscious experience -- and not just any conscious experience, your experience of the world around you and of yourself within it. How does this happen? According to neuroscientist Anil Seth, we're all hallucinating all the time; when we agree about our hallucinations, we call it "reality." Join Seth for a delightfully disorienting talk that may leave you questioning the very nature of your existence.

Rank #2: The search for our solar system's ninth planet | Mike Brown

Podcast cover
Read more
Could the strange orbits of small, distant objects in our solar system lead us to a big discovery? Planetary astronomer Mike Brown proposes the existence of a new, giant planet lurking in the far reaches of our solar system -- and shows us how traces of its presence might already be staring us in the face.

Rank #3: Emergency medicine for our climate fever | Kelly Wanser

Podcast cover
Read more
As we recklessly warm the planet by pumping greenhouse gases into the atmosphere, some industrial emissions also produce particles that reflect sunshine back into space, putting a check on global warming that we're only starting to understand. Climate activist Kelly Wanser asks: Can we engineer ways to harness this effect and further reduce warming? Learn more about the promises and risks of "cloud brightening" -- and how it could help restore our climate to health.

Rank #4: You aren't at the mercy of your emotions -- your brain creates them | Lisa Feldman Barrett

Podcast cover
Read more
Can you look at someone's face and know what they're feeling? Does everyone experience happiness, sadness and anxiety the same way? What are emotions anyway? For the past 25 years, psychology professor Lisa Feldman Barrett has mapped facial expressions, scanned brains and analyzed hundreds of physiology studies to understand what emotions really are. She shares the results of her exhaustive research -- and explains how we may have more control over our emotions than we think.

Rank #6: The next software revolution: programming biological cells | Sara-Jane Dunn

Podcast cover
Read more
The cells in your body are like computer software: they're "programmed" to carry out specific functions at specific times. If we can better understand this process, we could unlock the ability to reprogram cells ourselves, says computational biologist Sara-Jane Dunn. In a talk from the cutting-edge of science, she explains how her team is studying embryonic stem cells to gain a new understanding of the biological programs that power life -- and develop "living software" that could transform medicine, agriculture and energy.

Rank #7: The biology of gender, from DNA to the brain | Karissa Sanbonmatsu

Podcast cover
Read more
How exactly does gender work? It's not just about our chromosomes, says biologist Karissa Sanbonmatsu. In a visionary talk, she shares new discoveries from epigenetics, the emerging study of how DNA activity can permanently change based on social factors like trauma or diet. Learn how life experiences shape the way genes are expressed -- and what that means for our understanding of gender.

In this imaginative talk, neuroengineer Sam Rodriques takes us on a thrilling tour of the next 100 years in brain science. He envisions strange (and sometimes frightening) innovations that may be the key to understanding and treating brain disease -- like lasers that drill tiny holes in our skulls and allow probes to study the electrical activity of our neurons.

Rank #10: The fascinating (and dangerous) places scientists aren't exploring | Ella Al-Shamahi

Podcast cover

We're not doing frontline exploratory science in a huge portion of the world -- the places governments deem too hostile or disputed. What might we be missing because we're not looking? In this fearless, unexpectedly funny talk, paleoanthropologist Ella Al-Shamahi takes us on an expedition to the Yemeni island of Socotra -- one of the most biodiverse places on earth -- and makes the case for scientists to explore the unstable regions that could be home to incredible discoveries.

Rank #11: How early life experience is written into DNA | Moshe Szyf

Podcast cover
Read more
Moshe Szyf is a pioneer in the field of epigenetics, the study of how living things reprogram their genome in response to social factors like stress and lack of food. His research suggests that biochemical signals passed from mothers to offspring tell the child what kind of world they're going to live in, changing the expression of genes. "DNA isn't just a sequence of letters; it's not just a script." Szyf says. "DNA is a dynamic movie in which our experiences are being written."

In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.

Ocean expert Nancy Rabalais tracks the ominously named "dead zone" in the Gulf of Mexico -- where there isn't enough oxygen in the water to support life. The Gulf has the second largest dead zone in the world; on top of killing fish and crustaceans, it's also killing fisheries in these waters. Rabalais tells us about what's causing it -- and how we can reverse its harmful effects and restore one of America's natural treasures.
