Your lifelong health may have been decided the day you were born, says microbiome researcher Henna-Maria Uusitupa. In this fascinating talk, she shows how the gut microbes you acquire during birth and as an infant impact your health into adulthood -- and discusses new microbiome research that could help tackle problems like obesity and diabetes.
Why do we make poor decisions that we know are bad for our health? In this frank, funny talk, behavioral economist and health policy expert David Asch explains why our behavior is often irrational -- in highly predictable ways -- and shows how we can harness this irrationality to make better decisions and improve our health care system overall.
Could we anticipate the next big disease outbreak, stopping a virus like Ebola before it ever strikes? In this talk about frontline scientific research, ecologist Daniel Streicker takes us to the Amazon rainforest in Peru where he tracks the movement of vampire bats in order to forecast and prevent rabies outbreaks. By studying these disease patterns, Streicker shows how we could learn to cut off the next pandemic at its source.
Many diseases are driven by metabolites -- small molecules in your body like fat, glucose and cholesterol -- but we don't know exactly what they are or how they work. Biotech entrepreneur and TED Fellow Leila Pirhaji shares her plan to build an AI-based network to characterize metabolite patterns, better understand how disease develops -- and discover more effective treatments.
What if we could diagnose some of the world's deadliest diseases by the smells our bodies give off? In a fascinating talk and live demo, biologist James Logan introduces Freya, a malaria-sniffing dog, to show how we can harness the awesome powers of animal scent to detect chemical signatures associated with infection -- and change the way we diagnose disease.
Ninety-nine percent of cancer drugs never make it to tumors, getting washed out of the body before they have time to do their job. How can we better deliver life-saving drugs? Cancer researcher Joy Wolfram shares cutting-edge medical research into nanoparticles -- tiny particles that could be used to deliver drugs accurately to tumors -- and explains how they could keep drugs in the body longer to attack malignant cells.
The US health care system assumes many things about patients: that they can take off from work in the middle of the day, speak English, have a working telephone and a steady supply of food. Because of that, it's failing many of those who are most in need, says Mitchell Katz, CEO of the largest public health care system in the US. In this eye-opening talk, he shares stories of the challenges low-income patients face -- and how we can build a better system for all.
"Doctor, is this really necessary?" Backed by startling statistics about overtreatment, neurosurgeon Christer Mjåset explains the power of this and other simple questions in the context of medical treatment and surgery -- and shares how patients can better work with doctors to get the care they need.
In a moving talk, journalist Johann Hari shares fresh insights on the causes of depression and anxiety from experts around the world -- as well as some exciting emerging solutions. "If you're depressed or anxious, you're not weak and you're not crazy -- you're a human being with unmet needs," Hari says.
"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.
TV news anchor Lee Thomas thought his career was over after he was diagnosed with vitiligo, an autoimmune disorder that left large patches of his skin without pigment and led to derision and stares. In a captivating talk, he shares how he discovered a way to counter misunderstanding and fear around his appearance with engagement, dialogue -- and a smile. "Positivity is something worth fighting for, and the fight is not with others -- it's internal," Thomas says. "If you want to make positive changes in your life, you have to consistently be positive."
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.

this isn't 100 percent accurate as most states have multiple Medicaid managed care plans, so the burden of billing multiple insurers would still exist.

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.
