The most mysterious star in the universe | Tabetha Boyajian
00:13:46
Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/rDaUfAv_ixM" height="1" width="1" alt=""/>

How humans could evolve to survive in space | Lisa Nip
00:12:51
If we hope to one day leave Earth and explore the universe, our bodies are going to have to get a lot better at surviving the harsh conditions of space. Using synthetic biology, Lisa Nip hopes to harness special powers from microbes on Earth -- such as the ability to withstand radiation -- to make humans more fit for exploring space. "We're approaching a time during which we'll have the capacity to decide our own genetic destiny," Nip says. "Augmenting the human body with new abilities is no longer a question of how, but of when."<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/b88a3tAW_rs" height="1" width="1" alt=""/>

We can reprogram life. How to do it wisely | Juan Enriquez
00:14:49
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. "This is the single most exciting adventure human beings have been on," Enriquez says. "This is the single greatest superpower humans have ever had."<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/tDZkS2VZKgc" height="1" width="1" alt=""/>

Your kids might live on Mars. Here's how they'll survive | Stephen Petranek
00:17:14
It sounds like science fiction, but journalist Stephen Petranek considers it fact: within 20 years, humans will live on Mars. In this provocative talk, Petranek makes the case that humans will become a spacefaring species and describes in fascinating detail how we'll make Mars our next home. "Humans will survive no matter what happens on Earth," Petranek says. "We will never be the last of our kind."<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/xczV05DRgXQ" height="1" width="1" alt=""/>

Hunting for dinosaurs showed me our place in the universe | Kenneth Lacovara
00:15:49
What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus -- a 77-million-year-old sauropod that was as tall as a two-story house and as heavy as a jumbo jet -- and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth's geological history and contemplate our place in deep time.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/RfNAl3wDhHo" height="1" width="1" alt=""/>

How to read the genome and build a human being | Riccardo Sabatini
00:15:28
Secrets, disease and beauty are all written in the human genome, the complete set of genetic instructions needed to build a human being. Now, as scientist and entrepreneur Riccardo Sabatini shows us, we have the power to read this complex code, predicting things like height, eye color, age and even facial structure -- all from a vial of blood. And soon, Sabatini says, our new understanding of the genome will allow us to personalize treatments for diseases like cancer. We have the power to change life as we know it. How will we use it?<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/x886I4h7FqY" height="1" width="1" alt=""/>

Gene editing can now change an entire species -- forever | Jennifer Kahn
00:12:25
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, the technology has led to questions: How will this new power affect humanity? What are we going to use it to change? Are we gods now? Join journalist Jennifer Kahn as she ponders these questions and shares a potentially powerful application of gene drives: the development of disease-resistant mosquitoes that could knock out malaria and Zika.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/mrv6GCLIEpo" height="1" width="1" alt=""/>

This scientist makes ears out of apples | Andrew Pelling
00:07:05
TED Fellow 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 cheaply. And he has some even wilder ideas to share ... "What I'm really curious about is if one day it will be possible to repair, rebuild and augment our own bodies with stuff we make in the kitchen," he says.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/vunJsTi6IAE" height="1" width="1" alt=""/>

Why genetic research must be more diverse | Keolu Fox
00:06:48
Ninety-six percent of genome studies are based on people of European descent. The rest of the world is virtually unrepresented -- and this is dangerous, says geneticist and TED Fellow Keolu Fox, because we react to drugs differently based on our genetic makeup. Fox is working to democratize genome sequencing, specifically by advocating for indigenous populations to get involved in research, with the goal of eliminating health disparities. "The research community needs to immerse itself in indigenous culture," he says, "or die trying."<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/5hmzgfkZNFY" height="1" width="1" alt=""/>

How a blind astronomer found a way to hear the stars | Wanda Diaz Merced
00:11:15
Wanda Diaz Merced studies the light emitted by gamma-ray bursts, the most energetic events in the universe. When she lost her sight and was left without a way to do her science, she had a revelatory insight: the light curves she could no longer see could be translated into sound. Through sonification, she regained mastery over her work, and now she's advocating for a more inclusive scientific community. "Science is for everyone," she says. "It has to be available to everyone, because we are all natural explorers."<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/OBfR8PwOjHg" height="1" width="1" alt=""/>

Let's clean up the space junk orbiting Earth | Natalie Panek
00:10:15
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 impact of the satellites we rely on. Our orbital environment is breathtakingly beautiful and our gateway to exploration, she says. It's up to us to keep it that way.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/dE-w3y5xeHI" height="1" width="1" alt=""/>

How early life experience is written into DNA | Moshe Szyf
00:16:35
Moshe Szyf is a pioneer in the field of epigenetics, the study of how living things reprogram their genome in response to social factors like stress and lack of food. His research suggests that biochemical signals passed from mothers to offspring tell the child what kind of world they're going to live in, changing the expression of genes. "DNA isn't just a sequence of letters; it's not just a script." Szyf says. "DNA is a dynamic movie in which our experiences are being written."<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/3ze-khf7TR4" height="1" width="1" alt=""/>

How to take a picture of a black hole | Katie Bouman
00:12:51
At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of that shadow could help answer some important questions about the universe. Scientists used to think that making such an image would require a telescope the size of Earth -- until Katie Bouman and a team of astronomers came up with a clever alternative. Bouman explains how we can take a picture of the ultimate dark using the Event Horizon Telescope.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/zfSuJgo9Rb0" height="1" width="1" alt=""/>

The doctors, nurses and aid workers rebuilding Syria | Rola Hallam
00:07:07
Local humanitarians are beacons of light in the darkness of war, says humanitarian aid entrepreneur and TED Fellow Rola Hallam. She's working to help responders on the ground in devastated communities like Syria, where the destruction of health care is being used as a weapon of war. One of her campaigns achieved a global first: a crowdfunded hospital. Since it opened in 2017, the aptly named Hope Hospital has treated thousands of children. "Local humanitarians have the courage to persist, to dust themselves off from the wreckage and to start again, risking their lives to save others," Hallam says. "We can match their courage by not looking away or turning our backs."<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/BZ8nUoOPclM" height="1" width="1" alt=""/>

Emergency medicine for our climate fever | Kelly Wanser
00:14:49
As we recklessly warm the planet by pumping greenhouse gases into the atmosphere, some industrial emissions also produce particles that reflect sunshine back into space, putting a check on global warming that we're only starting to understand. Climate activist Kelly Wanser asks: Can we engineer ways to harness this effect and further reduce warming? Learn more about the promises and risks of "cloud brightening" -- and how it could help restore our climate to health.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/OiYzVUGYHgw" height="1" width="1" alt=""/>
