Through documentary films following survivors of trauma, TED Fellow Almudena Toral makes invisible psychological scars seen. She shares the heartbreaking story of Adayanci Pérez, a six-year-old girl from Guatemala suffering from post-traumatic stress disorder (PTSD) due to her encounter with US immigration enforcement. A powerful call to give voice to those who are silenced -- and pressure governments to change their course of action.

TED Fellow Zahra Al-Mahdi was raised by screens -- "storytelling machines" like TV and the internet that shaped her sense of self and reality. Now a multimedia artist and filmmaker, she challenges common historical narratives and brings a multiplicity of perspectives to the surface. In this dynamic talk, Al-Mahdi traces her development as a storyteller using satire, dark humor and tactile collage techniques to expand what we think we know about ourselves.

Society has a set of stories it tells itself about who refugees are and what they look like, says documentarian and TED Fellow Feras Fayyad. With his films, he's on a mission to separate the facts about refugees from fiction, as a form of resistance -- for himself, his daughter and the millions of other Syrian refugees across the world. A harrowing account, a quest to end injustice and a testament to the power of storytelling.

Of all the mundane yet astonishing marvels of human ingenuity, knowing what it takes to heat a room to a comfortable temperature is TED Fellow Kathy Hannun's favorite. She takes us on a journey across the planet and under the sea to emphasize the dangers of modern heating, and offers a safer, planet-friendly alternative that taps into the geothermal energy right below our feet.

Overcrowded clinics, extensive wait times and overworked doctors are taking a devastating toll on mothers and children in India. In this eye-opening talk, urogynecologist and TED Fellow Aparna Hegde exposes the systemic gaps that lead to preventable deaths every minute -- and introduces scalable, affordable and empowering tech solutions that improve maternal and child health outcomes, upend patriarchal family dynamics and save lives.

The universe started with a bang -- but how will it end? With astonishing visuals, cosmologist and TED Fellow Katie Mack takes us to the theoretical end of everything, some trillions of years in the future, in a profound meditation on existence, wonder and the legacy of humanity within the immensity of time and space.

One day, humans will explore space en masse and live scattered across the solar system on planets like Mars and beyond. Inspired by his time as artist-in-residence at the European Space Agency, TED Fellow Jorge Mañes Rubio wants to rethink what we need to bring on this grand journey -- and more importantly, what we should leave behind. Mañes Rubio takes us on an Earthbound journey through cultural practices and his own designs that blend science, art and ritual, encouraging a bold reimagining of what a future free of prejudice and exploitation could look like.

In this gripping talk, litigator and TED Fellow Itamar Mann details the perilous boat migrations of asylum seekers crossing the Mediterranean Sea. With a surplus of evidence gathered by researchers and activists, he explains how lawyers are making progress in prosecuting human rights abuses happening on militarized coasts. On a basic human level, Mann speaks to the obligation we have to defend each other's right to a dignified life -- because the future of how we inhabit the planet together depends on it.

Introducing a new type of public space, custom-fit for communities in need of a shot of hope and wonder. Artist and TED Fellow Matthew Mazzotta takes us across the US, sharing delightful projects that refresh space and place, spark collective conversation and reignite a sense of possibility and purpose in their surroundings.

We need an inside-out approach to how we diagnose disease, says immuno-engineer and TED Fellow Aaron Morris. Introducing cutting-edge medical research, he unveils implantable technology that gives real-time, continuous analysis of a patient's health at the molecular level. "We're creating a diagnostic lab inside your body," Morris says -- and it may pave the way to diagnosing and treating disease better and faster than ever before.

Kenya's minibuses -- known as "matatus" -- offer a convenient, affordable and colorful way for people to get around. But they also pose safety risks and accessibility issues for many of their passengers, especially women. Bringing a feminist perspective, activist and TED Fellow Naomi Mwaura calls for a revolution in public transportation by making routes transparent, protecting passengers from harassment and paving a career path for women in the industry.

If you can't afford an attorney, one will be appointed for you, right? Not in US civil court. From high legal fees to confusing paperwork and expensive lawyers, it can be difficult to settle civil matters. Entrepreneur and TED Fellow Rohan Pavuluri is working to streamline cumbersome legal processes with an app that empowers people to solve their own legal problems.

Could a small jolt of electricity to your gut help treat chronic diseases? Medical hacker and TED Fellow Khalil Ramadi is developing a new, noninvasive therapy that could treat diseases like diabetes, obesity, Parkinson's and Alzheimer's with an electronic pill. More targeted than a traditional pill and less invasive than surgery, these micro-devices contain electronics that deliver "bionudges" -- bursts of electrical or chemical stimuli -- to the gut, potentially helping control appetite, aid digestion, regulate hormones -- and even stimulate happiness in the brain.

Astrophysicist and TED Fellow Sarah Rugheimer searches for aliens -- but not the cartoony green kind. She's looking for extraterrestrial microbes by studying how these single-celled organisms emit gases, which could reveal evidence of them throughout the cosmos. Wondering if we're really alone in the universe, Rugheimer identifies two big hurdles to confirming life on another world and offers insight into what finding it might mean for us.

A phone call to a US prison or jail can cost up to a dollar per minute -- a rate that forces one in three families with incarcerated loved ones into debt. In this searing talk about mass incarceration, criminal justice advocate and TED Fellow Bianca Tylek exposes the predatory nature of the billion-dollar prison telecom industry and presents straightforward strategies to dismantle the network of corporations that has a financial interest in seeing more people behind bars for longer periods of time.
