"A record of our emotional life is written on our hearts," says cardiologist and author Sandeep Jauhar. In a stunning talk, he explores the mysterious ways our emotions impact the health of our hearts -- causing them to change shape in response to grief or fear, to literally break in response to emotional heartbreak -- and calls for a shift in how we care for our most vital organ.
Could psychedelics help us heal from trauma and mental illnesses? Researcher Rick Doblin has spent the past three decades investigating this question, and the results are promising. In this fascinating dive into the science of psychedelics, he explains how drugs like LSD, psilocybin and MDMA affect your brain -- and shows how, when paired with psychotherapy, they could change the way we treat PTSD, depression, substance abuse and more.
Being open and vulnerable with your loneliness, sadness and fear can help you find comfort and feel less alone, says writer and artist Jonny Sun. In an honest talk filled with his signature illustrations, Sun shares how telling stories about feeling like an outsider helped him tap into an unexpected community and find a tiny sliver of light in the darkness.
The world-changing promise of synthetic biology and gene editing has a dark side. In this far-seeing talk, author and entrepreneur Rob Reid reviews the risks of a world where more and more people have access to the tools and tech needed to create a doomsday bug that could wipe out humanity -- and suggests that it's time to take this danger seriously.
E-cigarettes and vapes have exploded in popularity in the last decade, especially among youth and young adults -- from 2011 to 2015, e-cigarette use among high school students in the US increased by 900 percent. Biobehavioral scientist Suchitra Krishnan-Sarin explains what you're actually inhaling when you vape (hint: it's definitely not water vapor) and explores the disturbing marketing tactics being used to target kids. "Our health, the health of our children and our future generations is far too valuable to let it go up in smoke -- or even in aerosol," she says.
Can we make tattoos both beautiful and functional? Nanotechnologist Carson Bruns shares his work creating high-tech tattoos that react to their environment -- like color-changing ink that can tell you when you're getting a sunburn -- and shows exciting ways they can deliver real-time information about our health.
Sleep is your life-support system and Mother Nature's best effort yet at immortality, says sleep scientist Matt Walker. In this deep dive into the science of slumber, Walker shares the wonderfully good things that happen when you get sleep -- and the alarmingly bad things that happen when you don't, for both your brain and body. Learn more about sleep's impact on your learning, memory, immune system and even your genetic code -- as well as some helpful tips for getting some shut-eye.
You use your brain's executive function every day -- it's how you do things like pay attention, plan ahead and control impulses. Can you improve it to change for the better? With highlights from her research on child development, cognitive scientist Sabine Doebel explores the factors that affect executive function -- and how you can use it to break bad habits and achieve your goals.
Here's a shocking statistic: 50 to 80 percent of people in the criminal justice system in the US have had a traumatic brain injury. In the general public, that number is less than five percent. Neuropsychologist Kim Gorgens shares her research into the connection between brain trauma and the behaviors that keep people in the revolving door of criminal justice -- and some ways to make the system more effective and safer for everyone.
Every year worldwide, more than 50,000 otherwise healthy people with epilepsy suddenly die -- a condition known as SUDEP. These deaths may be largely preventable, says AI researcher Rosalind Picard. Learn how Picard helped develop a cutting-edge smartwatch that can detect epileptic seizures as they occur and alert nearby loved ones in time to help.

What a fascinating talk this was! Seeing how much the heart is actually susceptible when it comes to our wellbeing makes me want to ensure that I'm looking after myself all the more knowing a little better today than I did yesterday about the synchronicity between heart and emotional state.
