Episode Date
The riddle of experience vs. memory | Daniel Kahneman
00:20:06
Using examples from vacations to colonoscopies, Nobel laureate and founder of behavioral economics Daniel Kahneman reveals how our "experiencing selves" and our "remembering selves" perceive happiness differently. This new insight has profound implications for economics, public policy -- and our own self-awareness.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/i0tUH2X3PUs" height="1" width="1" alt=""/>

How a fly flies | Michael Dickinson
00:15:55
An insect's ability to fly is one of the greatest feats of evolution. Michael Dickinson looks at how a fruit fly takes flight with such delicate wings, thanks to a clever flapping motion and flight muscles that are both powerful and nimble. But the secret ingredient: the incredible fly brain.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/d5CjXaaN0q4" height="1" width="1" alt=""/>

How to fight desertification and reverse climate change | Allan Savory
00:22:19
"Desertification is a fancy word for land that is turning to desert," begins Allan Savory in this quietly powerful talk. And it's happening to about two-thirds of the world's grasslands, accelerating climate change and causing traditional grazing societies to descend into social chaos. Savory has devoted his life to stopping it. He now believes -- and his work may show -- that a surprising factor can protect grasslands and even reclaim degraded land that was once desert. (NOTE: Statements in this talk have been challenged by scientists working in this field. Please read "Criticisms & Updates" below for more details.)<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/_RwjnbyWEQA" height="1" width="1" alt=""/>

How we found the giant squid | Edith Widder
00:08:38
Humankind has been looking for the giant squid (Architeuthis) since we first started taking pictures underwater. But the elusive deep-sea predator could never be caught on film. Oceanographer and inventor Edith Widder shares the key insight -- and the teamwork -- that helped to capture the squid on film for the first time.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/dn9Dky03xZs" height="1" width="1" alt=""/>

Your brain is more than a bag of chemicals | David Anderson
00:15:25
Modern psychiatric drugs treat the chemistry of the whole brain, but neurobiologist David Anderson has a more nuanced view of how the brain functions. He shares new research that could lead to targeted psychiatric medications -- that work better and avoid side effects. How's he doing it? For a start, by making a bunch of fruit flies angry.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/9cjTbnnsiCI" height="1" width="1" alt=""/>

The dawn of de-extinction. Are you ready? | Stewart Brand
00:18:24
Throughout humankind's history, we've driven species after species extinct: the passenger pigeon, the Eastern cougar, the dodo ... But now, says Stewart Brand, we have the technology (and the biology) to bring back species that humanity wiped out. So -- should we? Which ones? He asks a big question whose answer is closer than you may think.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/PATAYaMo_yU" height="1" width="1" alt=""/>

When you're making a deal, what's going on in your brain? | Colin Camerer
00:13:49
When two people are trying to make a deal -- whether they’re competing or cooperating -- what’s really going on inside their brains? Behavioral economist Colin Camerer shows research that reveals how badly we predict what others are thinking. Bonus: He presents an unexpected study that shows chimpanzees might just be better at it.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/cJHX7IZTZFQ" height="1" width="1" alt=""/>

The Philosophical Breakfast Club | Laura Snyder
00:12:34
In 1812, four men at Cambridge University met for breakfast. What began as an impassioned meal grew into a new scientific revolution, in which these men -- who called themselves “natural philosophers” until they later coined “scientist” -- introduced four major principles into scientific inquiry. Historian and philosopher Laura Snyder tells their intriguing story.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/8U8D-Ba9RQ4" height="1" width="1" alt=""/>

Parkinson's, depression and the switch that might turn them off | Andres Lozano
00:15:34
Deep brain stimulation is becoming very precise. This technique allows surgeons to place electrodes in almost any area of the brain, and turn them up or down -- like a radio dial or thermostat -- to correct dysfunction. Andres Lozano offers a dramatic look at emerging techniques, in which a woman with Parkinson's instantly stops shaking and brain areas eroded by Alzheimer's are brought back to life.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/L1drDt_c4CU" height="1" width="1" alt=""/>

Bring back the woolly mammoth! | Hendrik Poinar
00:10:22
It’s the dream of kids all around the world to see giant beasts walk the Earth again. Could -- and should -- that dream be realized? Hendrik Poinar talks about the next big thing: the quest to engineer a creature that looks very much like our furry friend, the woolly mammoth. The first step, to sequence the woolly genome, is nearly complete. And it’s huge.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/7t5_SHcp144" height="1" width="1" alt=""/>

Could we speak the language of dolphins? | Denise Herzing
00:14:38
For 28 years, Denise Herzing has spent five months each summer living with a pod of Atlantic spotted dolphins, following three generations of family relationships and behaviors. It's clear they are communicating with one another -- but is it language? Could humans use it too? She shares a fascinating new experiment to test this idea.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/Kpx_8Fx6hhg" height="1" width="1" alt=""/>

Is the obesity crisis hiding a bigger problem? | Peter Attia
00:15:58
As a young surgeon, Peter Attia felt contempt for a patient with diabetes. She was overweight, he thought, and thus responsible for the fact that she needed a foot amputation. But years later, Attia received an unpleasant medical surprise that led him to wonder: is our understanding of diabetes right? Could the precursors to diabetes cause obesity, and not the other way around? A look at how assumptions may be leading us to wage the wrong medical war.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/ihxdTfvE_PI" height="1" width="1" alt=""/>

How we'll resurrect the gastric brooding frog, the Tasmanian tiger | Michael Archer
00:17:36
The gastric brooding frog lays its eggs just like any other frog -- then swallows them whole to incubate. That is, it did until it went extinct 30 years ago. Paleontologist Michael Archer makes a case to bring back the gastric brooding frog and the thylacine, commonly known as the Tasmanian tiger.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/BXYA4V0NSoA" height="1" width="1" alt=""/>

A simple solution to the coming phosphorus crisis | Mohamed Hijri
00:13:41
There's a farming crisis no one is talking about: The world is running out of phosphorus, an essential element that's a key component of DNA and the basis of cellular communication. As biologist Mohamed Hijri shows, all roads of this crisis lead back to how we farm -- with chemical fertilizers chock-full of the element, which plants are not efficient at absorbing. One solution? A microscopic mushroom ...<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/pnemCJS-xzs" height="1" width="1" alt=""/>

Why we should build wooden skyscrapers | Michael Green
00:12:22
Building a skyscraper? Forget about steel and concrete, says architect Michael Green, and build it out of … wood. As he details in this intriguing talk, it's not only possible to build safe wooden structures up to 30 stories tall (and, he hopes, higher), it's necessary.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/GyBdfMIviQE" height="1" width="1" alt=""/>

The interspecies internet? An idea in progress | Vint Cerf
00:20:01
Apes, dolphins and elephants are animals with remarkable communication skills. Could the internet be expanded to include sentient species like them? A new and developing idea from a panel of four great thinkers -- dolphin researcher Diana Reiss, musician Peter Gabriel, internet of things visionary Neil Gershenfeld and Vint Cerf, one of the fathers of the internet.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/Gkctb5fjSVw" height="1" width="1" alt=""/>

The voice of the natural world | Bernie Krause
00:14:48
Bernie Krause has been recording wild soundscapes -- the wind in the trees, the chirping of birds, the subtle sounds of insect larvae -- for 45 years. In that time, he has seen many environments radically altered by humans, sometimes even by practices thought to be environmentally safe. A surprising look at what we can learn through nature's symphonies, from the grunting of a sea anemone to the sad calls of a beaver in mourning.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/vkvRp16j9VU" height="1" width="1" alt=""/>
Jul 15, 2013
Our shared condition -- consciousness | John Searle
00:14:59
Philosopher John Searle lays out the case for studying human consciousness -- and systematically shoots down some of the common objections to taking it seriously. As we learn more about the brain processes that cause awareness, accepting that consciousness is a biological phenomenon is an important first step. And no, he says, consciousness is not a massive computer simulation.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/Qr-4k6eT-HY" height="1" width="1" alt=""/>

Why I fell in love with monster prime numbers | Adam Spencer
00:17:17
They're millions of digits long, and it takes an army of mathematicians and machines to hunt them down -- what's not to love about monster primes? Adam Spencer, comedian and lifelong math geek, shares his passion for these odd numbers, and for the mysterious magic of math.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/B9OFwLU5u48" height="1" width="1" alt=""/>

A mouse. A laser beam. A manipulated memory. | Xu Liu
00:15:25
Can we edit the content of our memories? It's a sci-fi-tinged question that Steve Ramirez and Xu Liu are asking in their lab at MIT. Essentially, the pair shoot a laser beam into the brain of a living mouse to activate and manipulate its memory. In this unexpectedly amusing talk they share not only how, but -- more important -- why they do this.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/clUJozPBkNg" height="1" width="1" alt=""/>

3 reasons we still haven’t gotten rid of malaria | Sonia Shah
00:15:18
We’ve known how to cure malaria since the 1600s, so why does the disease still kill hundreds of thousands every year? It’s more than just a problem of medicine, says journalist Sonia Shah. A look into the history of malaria reveals three big-picture challenges to its eradication.

Why bees are disappearing | Marla Spivak
00:15:57
Honeybees have thrived for 50 million years, each colony 40 to 50,000 individuals coordinated in amazing harmony. So why, seven years ago, did colonies start dying en masse? Marla Spivak reveals four reasons which are interacting with tragic consequences. This is not simply a problem because bees pollinate a third of the world's crops. Could this incredible species be holding up a mirror for us?<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/tCzks_j-PhY" height="1" width="1" alt=""/>

How reliable is your memory? | Elizabeth Loftus
00:17:36
Psychologist Elizabeth Loftus studies memories. More precisely, she studies false memories, when people either remember things that didn't happen or remember them differently from the way they really were. It's more common than you might think, and Loftus shares some startling stories and statistics -- and raises some important ethical questions.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/SqCG7kHP3jw" height="1" width="1" alt=""/>

Why our universe might exist on a knife-edge | Gian Giudice
00:14:10
The biggest surprise of discovering the Higgs boson? That there were no surprises. Gian Giudice talks us through a problem in theoretical physics: what if the Higgs field exists in an ultra-dense state that could mean the collapse of all atomic matter? With wit and charm, Giudice outlines a grim fate -- and why we shouldn't start worrying just yet.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/D10CAsf0tso" height="1" width="1" alt=""/>

The paralyzed rat that walked | Grégoire Courtine
00:14:23
A spinal cord injury can sever the communication between your brain and your body, leading to paralysis. Fresh from his lab, Grégoire Courtine shows a new method -- combining drugs, electrical stimulation and a robot -- that could re-awaken the neural pathways and help the body learn again to move on its own. See how it works, as a paralyzed rat becomes able to run and navigate stairs.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/Hs3Xc_WAy1o" height="1" width="1" alt=""/>

How your "working memory" makes sense of the world | Peter Doolittle
00:09:29
"Life comes at us very quickly, and what we need to do is take that amorphous flow of experience and somehow extract meaning from it." In this funny, enlightening talk, educational psychologist Peter Doolittle details the importance -- and limitations -- of your "working memory," that part of the brain that allows us to make sense of what's happening right now.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/dm7FJs6BODw" height="1" width="1" alt=""/>

What is so special about the human brain? | Suzana Herculano-Houzel
00:13:31
The human brain is puzzling -- it is curiously large given the size of our bodies, uses a tremendous amount of energy for its weight and has a bizarrely dense cerebral cortex. But: why? Neuroscientist Suzana Herculano-Houzel puts on her detective's cap and leads us through this mystery. By making "brain soup," she arrives at a startling conclusion.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/A7CSb9CvU_c" height="1" width="1" alt=""/>

Body parts on a chip | Geraldine Hamilton
00:13:23
It's relatively easy to imagine a new medicine -- the hard part is testing it, and that can delay promising new cures for years. In this well-explained talk, Geraldine Hamilton shows how her lab creates organs and body parts on a chip, simple structures with all the pieces essential to testing new medications -- perhaps even custom cures made for one specific person.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/fzAuzaWGmaI" height="1" width="1" alt=""/>

The $80 prosthetic knee that's changing lives | Krista Donaldson
00:09:55
We've made incredible advances in technology in recent years, but too often it seems only certain fortunate people can benefit. Engineer Krista Donaldson introduces the ReMotion knee, a prosthetic device for above-knee amputees, many of whom earn less than $4 a day. The design contains best-in-class technology and yet is far cheaper than other prosthetics on the market.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/clbVyU7uScY" height="1" width="1" alt=""/>

A bold new way to fund drug research | Roger Stein
00:11:09
Believe it or not, about 20 years' worth of potentially life-saving drugs are sitting in labs right now, untested. Why? Because they can't get the funding to go to trials; the financial risk is too high. Roger Stein is a finance guy, and he thinks deeply about mitigating risk. He and some colleagues at MIT came up with a promising new financial model that could move hundreds of drugs into the testing pipeline.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/9owze-ruN6c" height="1" width="1" alt=""/>

Paper beats plastic? How to rethink environmental folklore | Leyla Acaroglu
00:18:07
Most of us want to do the right thing when it comes to the environment. But things aren’t as simple as opting for the paper bag, says sustainability strategist Leyla Acaroglu. A bold call for us to let go of tightly-held green myths and think bigger in order to create systems and products that ease strain on the planet.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/pmxZB5KLd8I" height="1" width="1" alt=""/>

Could future devices read images from our brains? | Mary Lou Jepsen
00:10:26
As an expert on cutting-edge digital displays, Mary Lou Jepsen studies how to show our most creative ideas on screens. And as a brain surgery patient herself, she is driven to know more about the neural activity that underlies invention, creativity, thought. She meshes these two passions in a rather mind-blowing talk on two cutting-edge brain studies that might point to a new frontier in understanding how (and what) we think.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/sOZ-o2Kez_g" height="1" width="1" alt=""/>

My DNA vending machine | Gabriel Barcia-Colombo
00:04:56
Vending machines generally offer up sodas, candy bars and chips. Not so for the one created by TED Fellow Gabe Barcia-Colombo. This artist has dreamed up a DNA Vending Machine, which dispenses extracted human DNA, packaged in a vial along with a collectible photo of the person who gave it. It’s charming and quirky, but points out larger ethical issues that will arise as access to biotechnology increases.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/RdmyqpoIBwM" height="1" width="1" alt=""/>

The neuroscience of restorative justice | Daniel Reisel
00:14:35
Daniel Reisel studies the brains of criminal psychopaths (and mice). And he asks a big question: Instead of warehousing these criminals, shouldn't we be using what we know about the brain to help them rehabilitate? Put another way: If the brain can grow new neural pathways after an injury ... could we help the brain re-grow morality?<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/ggm0oXyl0dU" height="1" width="1" alt=""/>

Zombie roaches and other parasite tales | Ed Yong
00:13:14
In this fascinating, hilarious and ever-so-slightly creepy talk, science writer Ed Yong tells the story of his favorite parasites -- animals and organisms that live on the bodies (and brains!) of other organisms, causing them to do their bidding. Do humans have them too? Maybe ...<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/ecESRPvpTGA" height="1" width="1" alt=""/>

The discovery that could rewrite physics | Allan Adams
00:04:42
On March 17, 2014, a group of physicists announced a thrilling discovery: the “smoking gun” data for the idea of an inflationary universe, a clue to the Big Bang. For non-physicists, what does it mean? TED asked Allan Adams to briefly explain the results, in this improvised talk illustrated by Randall Munroe of xkcd.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/LrKCa-qq9Gs" height="1" width="1" alt=""/>

The sore problem of prosthetic limbs | David Sengeh
00:04:43
What drove David Sengeh to create a more comfortable prosthetic limb? He grew up in Sierra Leone, and too many of the people he loves are missing limbs after the brutal civil war there. When he noticed that people who had prosthetics weren’t actually wearing them, the TED Fellow set out to discover why — and to solve the problem with his team from the MIT Media Lab.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/jviM4Po0Slc" height="1" width="1" alt=""/>

How synchronized hammer strikes could generate nuclear fusion | Michel Laberge
00:12:50
Our energy future depends on nuclear fusion, says Michel Laberge. The plasma physicist runs a small company with a big idea for a new type of nuclear reactor that could produce clean, cheap energy. His secret recipe? High speeds, scorching temperatures and crushing pressure. In this hopeful talk, he explains how nuclear fusion might be just around the corner.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/08b5n_C29tQ" height="1" width="1" alt=""/>

Tiny satellites show us the Earth as it changes in near-real-time | Will Marshall
00:08:01
Satellite imaging has revolutionized our knowledge of the Earth, with detailed images of nearly every street corner readily available online. But Planet Labs' Will Marshall says we can do better and go faster -- by getting smaller. He introduces his tiny satellites -- no bigger than 10 by 10 by 30 centimeters -- that, when launched in a cluster, provide high-res images of the entire planet, updated daily.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/eQwFLou4iVk" height="1" width="1" alt=""/>

Autism — what we know (and what we don't know yet) | Wendy Chung
00:15:35
In this factual talk, geneticist Wendy Chung shares what we know about autism spectrum disorder — for example, that autism has multiple, perhaps interlocking, causes. Looking beyond the worry and concern that can surround a diagnosis, Chung and her team look at what we've learned through studies, treatments and careful listening.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/NlnFhb-b3CA" height="1" width="1" alt=""/>

Get your next eye exam on a smartphone | Andrew Bastawrous
00:06:33
Thirty-nine million people in the world are blind, and the majority lost their sight due to curable and preventable diseases. But how do you test and treat people who live in remote areas, where expensive, bulky eye equipment is hard to come by? TED Fellow Andrew Bastawrous demos a smartphone app and cheap hardware that might help.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/7VsmF1BPesY" height="1" width="1" alt=""/>

The emergent patterns of climate change | Gavin Schmidt
00:12:10
You can't understand climate change in pieces, says climate scientist Gavin Schmidt. It's the whole, or it's nothing. In this illuminating talk, he explains how he studies the big picture of climate change with mesmerizing models that illustrate the endlessly complex interactions of small-scale environmental events.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/_2f4Bwl-uys" height="1" width="1" alt=""/>

The loves and lies of fireflies | Sara Lewis
00:13:51
Biologist Sara Lewis has spent the past 20 years getting to the bottom of the magic and wonder of fireflies. In this charming talk, she tells us how and why the beetles produce their silent sparks, what happens when two fireflies have sex, and why one group of females is known as the firefly vampire. (It's not pretty.) Find out more astonishing facts about fireflies in Lewis' footnotes, below.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/SRc9VJ415mw" height="1" width="1" alt=""/>

The psychology of your future self | Dan Gilbert
00:06:49
"Human beings are works in progress that mistakenly think they're finished." Dan Gilbert shares recent research on a phenomenon he calls the "end of history illusion," where we somehow imagine that the person we are right now is the person we'll be for the rest of time. Hint: that's not the case.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/dh6ryc8CCwk" height="1" width="1" alt=""/>

Why science demands a leap into the unknown | Uri Alon
00:15:52
While studying for his PhD in physics, Uri Alon thought he was a failure because all his research paths led to dead ends. But, with the help of improv theater, he came to realize that there could be joy in getting lost. A call for scientists to stop thinking of research as a direct line from question to answer, but as something more creative. It's a message that will resonate, no matter what your field.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/9CCJtaNs5go" height="1" width="1" alt=""/>

Why we should trust scientists | Naomi Oreskes
00:19:14
Many of the world's biggest problems require asking questions of scientists -- but why should we believe what they say? Historian of science Naomi Oreskes thinks deeply about our relationship to belief and draws out three problems with common attitudes toward scientific inquiry -- and gives her own reasoning for why we ought to trust science.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/JrIXnN8eXNY" height="1" width="1" alt=""/>

A tool to fix one of the most dangerous moments in surgery | Nikolai Begg
00:09:21
Surgeons are required every day to puncture human skin before procedures — with the risk of damaging what's on the other side. In a fascinating talk, find out how mechanical engineer Nikolai Begg is using physics to update an important medical device, called the trocar, and improve one of the most dangerous moments in many common surgeries.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/xJqESKx-XbY" height="1" width="1" alt=""/>

Crop insurance, an idea worth seeding | Rose Goslinga
00:10:04
Across sub-Saharan Africa, small farmers are the bedrock of national and regional economies—unless the weather proves unpredictable and their crops fail. The solution is insurance, at a vast, continental scale, and at a very low, affordable cost. Rose Goslinga and the Syngenta Foundation for Sustainable Agriculture pioneered an unconventional way to give farmers whose crops fail early a second chance at a growing season.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/CVjOe13EI0U" height="1" width="1" alt=""/>

Depressed dogs, cats with OCD — what animal madness means for us humans | Laurel Braitman
00:19:29
Behind those funny animal videos, sometimes, are oddly human-like problems. Laurel Braitman studies non-human animals who exhibit signs of mental health issues -- from compulsive bears to self-destructive rats to monkeys with unlikely friends. Braitman asks what we as humans can learn from watching animals cope with depression, sadness and other all-too-human problems.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/QY6d3OCdDdc" height="1" width="1" alt=""/>

The state of the climate — and what we might do about it | Nicholas Stern
00:16:33
How can we begin to address the global, insidious problem of climate change — a problem that's too big for any one country to solve? Economist Nicholas Stern lays out a plan, presented to the UN's Climate Summit in 2014, showing how the world's countries can work together on climate. It's a big vision for cooperation, with a payoff that goes far beyond averting disaster. He asks: How can we use this crisis to spur better lives for all?<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/u1qD7nk4c10" height="1" width="1" alt=""/>

What the Social Progress Index can reveal about your country | Michael Green
00:14:56
The term Gross Domestic Product is often talked about as if it were “handed down from god on tablets of stone.” But this concept was invented by an economist in the 1930s. We need a more effective measurement tool to match 21st century needs, says Michael Green: the Social Progress Index. With charm and wit, he shows how this tool measures societies across the three dimensions that actually matter.

How butterflies self-medicate | Jaap de Roode
00:06:15
Just like us, the monarch butterfly sometimes gets sick thanks to a nasty parasite. But biologist Jaap de Roode noticed something interesting about the butterflies he was studying — infected female butterflies would choose to lay their eggs on a specific kind of plant that helped their offspring avoid getting sick. How do they know to choose this plant?

Stellar astronomer and TED Senior Fellow Lucianne Walkowicz works on NASA's Kepler mission, searching for places in the universe that could support life. So it's worth a listen when she asks us to think carefully about Mars. In this short talk, she suggests that we stop dreaming of Mars as a place that we'll eventually move to when we've messed up Earth, and to start thinking of planetary exploration and preservation of the Earth as two sides of the same goal.

How Mars might hold the secret to the origin of life | Nathalie Cabrol

While we like to imagine little green men, it's far more likely that life on other planets will be microbial. Planetary scientist Nathalie Cabrol takes us inside the search for microbes on Mars, a hunt which counterintuitively leads us to the remote lakes of the Andes mountains. This extreme environment — with its thin atmosphere and scorched land — approximates the surface of Mars about 3.5 billion years ago. How microbes adapt to survive here may just show us where to look on Mars — and could help us understand why some microbial pathways lead to civilization while others are a dead end.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/qWYXwsX8iJI" height="1" width="1" alt=""/>

The forgotten history of autism | Steve Silberman
00:13:48
Decades ago, few pediatricians had heard of autism. In 1975, 1 in 5,000 kids was estimated to have it. Today, 1 in 68 is on the autism spectrum. What caused this steep rise? Steve Silberman points to “a perfect storm of autism awareness” — a pair of psychologists with an accepting view, an unexpected pop culture moment and a new clinical test. But to really understand, we have to go back further to an Austrian doctor by the name of Hans Asperger, who published a pioneering paper in 1944. Because it was buried in time, autism has been shrouded in misunderstanding ever since.

Have we reached the end of physics? | Harry Cliff
00:13:57
Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions. Despite the best efforts of scientists (and the help of the biggest machine on the planet), we may never be able to explain all the weird features of nature. Is this the end of physics?

How we can make crops survive without water | Jill Farrant
00:13:56
As the world's population grows and the effects of climate change come into sharper relief, we'll have to feed more people using less arable land. Molecular biologist Jill Farrant studies a rare phenomenon that may help: "resurrection plants" -- super-resilient plants that seemingly come back from the dead.

Should you be able to patent a human gene? | Tania Simoncelli
00:18:05
A decade ago, US law said human genes were patentable -- which meant patent holders had the right to stop anyone from sequencing, testing or even looking at a patented gene. Troubled by the way this law both harmed patients and created a barrier to biomedical innovation, Tania Simoncelli and her colleagues at the ACLU challenged it. In this riveting talk, hear the story of how they took a case everybody told them they would lose all the way to the Supreme Court.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/XTpK7umxQxk" height="1" width="1" alt=""/>

The boiling river of the Amazon | Andrés Ruzo
00:15:49
When Andrés Ruzo was a young boy in Peru, his grandfather told him a story with an odd detail: There is a river, deep in the Amazon, which boils as if a fire burns below it. Twelve years later, after training as a geoscientist, he set out on a journey deep into the jungle of South America in search of this boiling river. At a time when everything seems mapped and measured, join Ruzo as he explores a river that forces us to question the line between known and unknown ... and reminds us that there are great wonders yet to be discovered.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/rjOMN9ESoZk" height="1" width="1" alt=""/>

The case for fish farming | Mike Velings
00:15:18
We're headed towards a global food crisis: Nearly 3 billion people depend on the ocean for food, and at our current rate we already take more fish from the ocean than it can naturally replace. In this fact-packed, eye-opening talk, entrepreneur and conservationist Mike Velings proposes a solution: Aquaculture, or fish farming. "We must start using the ocean as farmers instead of hunters," he says, echoing Jacques Cousteau. "The day will come where people will demand farmed fish on their plates that's farmed well and farmed healthy -- and refuse anything less."<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/lNyzjV7cI1k" height="1" width="1" alt=""/>

What the discovery of gravitational waves means | Allan Adams
00:10:58
More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided. "All that energy was pumped into the fabric of time and space itself," says theoretical physicist Allan Adams, "making the universe explode in roiling waves of gravity." About 25 years ago, a group of scientists built a giant laser detector called LIGO to search for these kinds of waves, which had been predicted but never observed. In this mind-bending talk, Adams breaks down what happened when, in September 2015, LIGO detected an unthinkably small anomaly, leading to one of the most exciting discoveries in the history of physics.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/i1Q1Ew-xUCI" height="1" width="1" alt=""/>

Why your doctor should care about social justice | Mary Bassett
00:13:49
In Zimbabwe in the 1980s, Mary Bassett witnessed the AIDS epidemic firsthand, and she helped set up a clinic to treat and educate local people about the deadly virus. But looking back, she regrets not sounding the alarm for the real problem: the structural inequities embedded in the world's political and economic organizations, inequities that make marginalized people more vulnerable. These same structural problems exist in the United States today, and as New York City's Health Commissioner, Bassett is using every chance she has to rally support for health equity and speak out against racism. "We don't have to have all the answers to call for change," she says.

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/d7QIxT8NW5c" 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/XvHYELwjEmY" height="1" width="1" alt=""/>

The "dead zone" of the Gulf of Mexico | Nancy Rabalais
00:12:02
Ocean expert Nancy Rabalais tracks the ominously named "dead zone" in the Gulf of Mexico -- where there isn't enough oxygen in the water to support life. The Gulf has the second largest dead zone in the world; on top of killing fish and crustaceans, it's also killing fisheries in these waters. Rabalais tells us about what's causing it -- and how we can reverse its harmful effects and restore one of America's natural treasures.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/Z84RvOeIXOE" height="1" width="1" alt=""/>

The surprising science of alpha males | Frans de Waal
00:15:54
In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.<img src="http://feeds.feedburner.com/~r/iTunesPodcastTTScienceMedicine/~4/Wsdd49YADwE" 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/OrUS3OXaOwY" height="1" width="1" alt=""/>
