What do Tourette syndrome, heroin addiction and social media obsession all have in common? They converge in an area of the brain called the striatum, says neuroscientist Rachel Wurzman -- and this critical discovery could reshape our understanding of the opioid crisis. Sharing insights from her research, Wurzman shows how social isolation contributes to relapse and overdose rates and reveals how meaningful human connection could offer a potentially powerful source of recovery.
We may not be as deeply divided as we think -- at least when it comes to health, says Rebecca Onie. In a talk that cuts through the noise, Onie shares research that shows how, even across economic, political and racial divides, Americans agree on what they need to live good lives -- and asks both health care providers and patients to focus on what makes us healthy, not what makes us angry.
Kristie Overstreet is on a mission to ensure that the transgender community gets their health care needs met. In this informative, myth-busting talk, she provides a primer for understanding gender identity and invites us to shift how we view transgender health care -- so that everyone gets the respect and dignity they deserve when they go to a doctor.
What if we could help our bodies heal faster and without scars, like Wolverine in X-Men? TED Fellow Kaitlyn Sadtler is working to make this dream a reality by developing new biomaterials that could change how our immune system responds to injuries. In this quick talk, she shows the different ways these products could help the body regenerate.
Nobody likes going to the hospital, whether it's because of the logistical challenges of getting there, the astronomical costs of procedures or the alarming risks of complications like antibiotic-resistant bacteria. But what if we could get the lifesaving care provided by hospitals in our own homes? Health care futurist Niels van Namen shows how advances in technology are making home care a cheaper, safer and more accessible alternative to hospital stays.
For nearly half a century, scientists have been trying to create a process for transplanting animal organs into humans, a theoretical dream that could help the hundreds of thousands of people in need of a lifesaving transplant. But the risks, specifically of transmitting the PERV virus from pigs to humans, have always been too great, stalling research -- until now. In a mind-blowing talk, geneticist Luhan Yang explains a breakthrough: using CRISPR, a technique for editing genes, she and her colleagues have created pigs that don't carry the virus, opening up the possibility of safely growing human-transplantable organs in pigs. Learn more about this cutting-edge science and how it could help solve the organ shortage crisis.
In 2011, eye surgeon and TED Fellow Andrew Bastawrous developed a smartphone app that brings quality eye care to remote communities, helping people avoid losing their sight to curable or preventable conditions. Along the way, he noticed a problem: strict funding regulations meant that he could only operate on people with specific diseases, leaving many others without resources for treatment. In this passionate talk, Bastawrous calls for a new health care funding model that's flexible and ambitious -- to deliver better health to everyone, whatever their needs are.
When faced with life's toughest circumstances, how should we respond: as an optimist, a realist or something else? In an unforgettable talk, explorer Mark Pollock and human rights lawyer Simone George explore the tension between acceptance and hope in times of grief -- and share the groundbreaking work they're undertaking to cure paralysis.
In 2012, Colorado legalized cannabis and added to what has fast become a multibillion-dollar global industry for all things weed-related: from vape pens to brownies and beyond. But to say that we've legalized marijuana is subtly misleading -- what we've really done is commercialized THC, says educator Ben Cort, and that's led to products that are unnaturally potent. In an eye-opening talk, Cort examines the often unseen impacts of the commercial cannabis industry -- and calls on us to question those who are getting rich off of it.
When cancer cells are closely packed together in a tumor, they're able to communicate with each other and coordinate their movement throughout the body. What if we could interrupt this process? In this accessible talk about cutting-edge science, Hasini Jayatilaka shares her work on an innovative method to stop cancer cells from communicating -- and halt their fatal ability to spread.
Tobacco causes more than seven million deaths every year -- and many of us are far more complicit in the problem than we realize. In a bold talk, oncologist Dr. Bronwyn King tells the story of how she uncovered the deep ties between the tobacco industry and the entire global finance sector, which invests our money in cigarette companies through big banks, insurers and pension funds. Learn how Dr. King has ignited a worldwide movement to create tobacco-free investments and how each of us can play a role in ending this epidemic.
The United States accounts for five percent of the world's population but consumes almost 70 percent of the total global opioid supply, creating an epidemic that has resulted in tens of thousands of deaths each year. How did we get here, and what can we do about it? In this personal talk, Travis Rieder recounts the painful, often-hidden struggle of opioid withdrawal and reveals how doctors who are quick to prescribe (and overprescribe) opioids aren't equipped with the tools to eventually get people off the meds.
Thousands of years ago, ancient Nubians drew pictures on tomb walls of a terrible disease that turns the eyelids inside out and causes blindness. This disease, trachoma, is still a scourge in many parts of the world today -- but it's also completely preventable, says Caroline Harper. Armed with data from a global mapping project, Harper's organization Sightsavers has a plan: to focus on countries where funding gaps stand in the way of eliminating the disease and ramp up efforts where the need is most severe. Learn more about their goal of consigning trachoma to the history books -- and how you can help. (This ambitious plan is one of the first ideas of The Audacious Project, TED's new initiative to inspire global change.)
The global refugee crisis is a mental health catastrophe, leaving millions in need of psychological support to overcome the traumas of dislocation and conflict. To undo the damage, child psychiatrist and TED Fellow Essam Daod has been working in camps, rescue boats and the shorelines of Greece and the Mediterranean Sea to help refugees (a quarter of which are children) reframe their experiences through short, powerful psychological interventions. "We can all do something to prevent this mental health catastrophe," Daod says. "We need to acknowledge that first aid is not just needed for the body, but it has also to include the mind, the soul."
Public libraries have always been about more than just books -- and their mission of community support has taken on new urgency during the current opioid epidemic. After witnessing overdoses at her library in Philadelphia, Chera Kowalski learned how to administer naloxone, a drug that reverses the effects of narcotics, and she's put it to use to save patrons' lives. In this personal talk, she shares the day-to-day reality of life on the frontline of the opioid crisis and advocates for each of us to find new ways to keep our communities safe and healthy.
