TED: Let’s clean up the space junk orbiting Earth | Natalie Panek

Our lives depend on a world we can’t see: the satellite infrastructure we use every day for information, entertainment, communication and so much more. But Earth orbit isn’t a limitless resource, and the problem of space debris will get worse without a significant change to our behavior. Natalie Panek challenges us to consider the environmental …

TED: Math is the hidden secret to understanding the world | Roger Antonsen

Unlock the mysteries and inner workings of the world through one of the most imaginative art forms ever — mathematics — with Roger Antonsen, as he explains how a slight change in perspective can reveal patterns, numbers and formulas as the gateways to empathy and understanding.  

TED: What will humans look like in 100 years? | Juan Enriquez

We can evolve bacteria, plants and animals — futurist Juan Enriquez asks: Is it ethical to evolve the human body? In a visionary talk that ranges from medieval prosthetics to present day neuroengineering and genetics, Enriquez sorts out the ethics associated with evolving humans and imagines the ways we’ll have to transform our own bodies …

TED: What you need to know about CRISPR | Ellen Jorgensen

Should we bring back the wooly mammoth? Or edit a human embryo? Or wipe out an entire species that we consider harmful? The genome-editing technology CRISPR has made extraordinary questions like these legitimate — but how does it work? Scientist and community lab advocate Ellen Jorgensen is on a mission to explain the myths and …

TED: Sam Harris | Can we build AI without losing control over it?

Scared of superintelligent AI? You should be, says neuroscientist and philosopher Sam Harris — and not just in some theoretical way. We’re going to build superhuman machines, says Harris, but we haven’t yet grappled with the problems associated with creating something that may treat us the way we treat ants.  

TED: A new way to heal hearts without surgery | Franz Freudenthal

At the intersection of medical invention and indigenous culture, pediatric cardiologist Franz Freudenthal mends holes in the hearts of children across the world, using a device born from traditional Bolivian loom weaving. “The most complex problems in our time,” he says, “can be solved with simple techniques, if we are able to dream.”  

TED: What a planet needs to sustain life | Dave Brain

“Venus is too hot, Mars is too cold, and Earth is just right,” says planetary scientist Dave Brain. But why? In this pleasantly humorous talk, Brain explores the fascinating science behind what it takes for a planet to host life — and why humanity may just be in the right place at the right time …

TED: A new way to study the brain’s invisible secrets | Ed Boyden

Neuroengineer Ed Boyden wants to know how the tiny biomolecules in our brains generate emotions, thoughts and feelings — and he wants to find the molecular changes that lead to disorders like epilepsy and Alzheimer’s. Rather than magnify these invisible structures with a microscope, he wondered: What if we physically enlarge them and make them …

TED: This scientist makes ears out of apples | Andrew Pelling

Andrew Pelling is a biohacker, and nature is his hardware. His favorite materials are the simplest ones (and oftentimes he finds them in the garbage). Building on the cellulose structure that gives an apple its shape, he “grows” lifelike human ears, pioneering a process that might someday be used to repair body parts safely and …

TED: This tiny particle could roam your body to find tumors | Sangeeta Bhatia

What if we could find cancerous tumors years before they can harm us — without expensive screening facilities or even steady electricity? Physician, bioengineer and entrepreneur Sangeeta Bhatia leads a multidisciplinary lab that searches for novel ways to understand, diagnose and treat human disease. Her target: the two-thirds of deaths due to cancer that she …

TED: We can reprogram life. How to do it wisely | Juan Enriquez

For four billion years, what lived and died on Earth depended on two principles: natural selection and random mutation. Then humans came along and changed everything — hybridizing plants, breeding animals, altering the environment and even purposefully evolving ourselves. Juan Enriquez provides five guidelines for a future where this ability to program life rapidly accelerates. …

TED: A new superweapon in the fight against cancer | Paula Hammond

Cancer is a very clever, adaptable disease. To defeat it, says medical researcher and educator Paula Hammond, we need a new and powerful mode of attack. With her colleagues at MIT, Hammond engineered a nanoparticle one-hundredth the size of a human hair that can treat the most aggressive, drug-resistant cancers. Learn more about this molecular …

TED: Gene editing can now change an entire species — forever | Jennifer Kahn

CRISPR gene drives allow scientists to change sequences of DNA and guarantee that the resulting edited genetic trait is inherited by future generations, opening up the possibility of altering entire species forever. More than anything, this technology has led to questions: How will this new power affect humanity? What are we going to use it …
