TED Radio Hour: Hacking our way to a better world

Technology

the_hackers_deskThis week’s TED Radio Hour examines the hacker, a term often associated with computer crime. But, as host Guy Raz tells us, “All of our TED speakers today are hacking for good — hacking into our brains, into the environment, even into the DNA of extinct animals — hackers trying to save the world.”

First up, Mikko Hypponen, the programmer who visited the creators of The_Brain, the very first computer virus that plagued the technology world in 1986. In his talk from 2011, Hypponen tells the story of how his investigation of the virus led him to an address in Pakistan. Embedded in the code of an infected floppy disk, Hypponen found English text that said, “Welcome to the dungeon 1986. Beware of this virus. Contact us for vaccination.” Following their instructions, Hypponen found himself face to face with the people who had made history. The reason they did it: to prove that the new PC computers were insecure. it’s evidence that the first hackers were actually good hackers.

The next TED speaker in the episode is a completely different kind of hacker. Stewart Brand is using DNA from fossils and preserved specimens to bring a species back from extinction. In his talk from TED2013, he tells the story of Martha, the last living passenger pigeon who died on September 1, 1914. Brand and his colleagues are engaged in “resurrection biology,” also known as “de-extinction.” The idea is to insert genes from an extinct species into a closely related living species. Brand says he is using hacking to organize the past. “Sorrow, anger, mourning?” he says. “Don’t mourn; organize.”

David Keith imagines hacking the planet — the idea that we could correct climate change by manipulating the stratosphere. As he explains in his TED Talk, the addition of sulfuric acid droplets to the stratosphere could create small wisps of cloud that can deflect some of the sun’s rays. Adding one pollutant to another could cool the global temperature back down again. But the unintended consequences could be dire. Just as people drive faster when they have an airbag in their car, would such scientific manipulation keep us from truly solving the problems with our environment? Keith concludes, “The understanding of nature gives us power to do great harm as well as, potentially, power to do good..”

Jay Silver is the most literal hacker on the show, and he gives us an interesting way to think about the job. “A hacker is someone who doesn’t ask how something works, they just see what works,” he says. He compares his work to a kid who tries something over and over again in order to explore the different possibilities. The creator of the Makey-Makey, Silver suggests that almost everything is hackable: “Humans, plants, kitty cats, grandmas, water, graphite.” For Silver, hacking has made the very landscape of life a form of expression.

Closing out the episode this week is Andres Lozano, the renowned neurosurgeon who is hacking into the human brain. Lozano explains how it is possible to adjust the circuits of the human brain using electricity, turning up or down areas of activity using something similar to a remote control. In his TED Talk, Lozano shows a video of a woman with Parkinson’s disease and demonstrates his technique by alleviating her tremor almost entirely.

Having conquered the control of movement, Lozano suggests, could we also use this technique to clear the dark cloud of depression? In the episode, he broaches the controversial subject of what he calls “cosmetic brain surgery.” He says that the possibility of altering cognitive personality is within reach and describes it as “mapping an unexplored galaxy, an unexplored universe.” But like David Keith’s issues with manipulating the atmosphere, the celebration of human ingenuity is not the only consideration here. Lozano asks the important questions: should we be messing with intrinsic personality? And is it fair that only the rich will have this expensive opportunity?

All these speakers prove that humans have developed incredible ways to manipulate the universe — but just because we can, doesn’t mean we should. The question, then: Who should be making the decisions?

TED Radio Hour takes us “To the Edge”

Culture

to_the_edge_art“By inspiring ourselves, we inspire others.” These are the words of tightrope walker Philippe Petit in this week’s TED Radio Hour from NPR, “To the Edge.” hosted by Guy Raz. The episode overflows with speakers who have gone to the edge in some way: rowing across oceans; exploring caves as deep as Mount Everest is tall; and wire-walking thousands of feet above the ground, like Petit. The big question: why?

Ben Saunders, explorer of all places cold and white, kicks off the episode with the story of his journey to the North Pole. In his talk from TED2005, Saunders repeats a famous quotation from mountaineer George Mallory. He was asked why he wanted to climb Everest. Mallory responded, “Because it is there… What we get from this adventure is just sheer joy, and joy, after all, is the end of life.” Saunders agrees. Although nature can feel like the enemy during a climb, “true, real inspiration and growth only comes from adversity and challenge; from stepping away from what’s comfortable and familiar and stepping out into the unknown.” Saunders is addicted to “tasting life at the edge of what is humanly possible.” And so it seems, are the other three speakers on the show.

Raz introduces Bill Stone next, a TED speaker who explores the depths of the earth, descending into caves as deep as Everest is tall. Drawing on his talk from TED2007, Stone calls these holes “the last terrestrial frontier for humans” and shows how he and his team put themselves through months of sensory deprivation for the sake of a few extra squiggles on a map. Stone describes a “crushing psychological remoteness that begins to hit every member of the team once you get about three days inbound from the nearest entrance.” It’s a sentiment shared by Ben Saunders in his perpetually white surroundings.

Roz Savage, the marketing consultant who traded her gray cubicle for the Atlantic Ocean, had a different perspective on that feeling of remoteness, as she says in her TED Talk from 2010. Having spent 20 years feeling like a battery-farm chicken in her overpopulated office, Savage decided that her real calling in life was rowing across the world’s greatest expanses of water. The experience was liberating: “I just felt incredibly tiny and humble but at the same time very much connected to and part of it all. A lot of time on the ocean I just lost track of self … you’re just another creature. There’s real freedom to be found in that simplicity.”

Philippe Petit is the final speaker in the episode. While all the speakers here pushed themselves to the edge of human capabilities, Petit went to the edge and then stepped off. He walked on a thin steel wire strung up on some of the world’s greatest stages: the Sydney Harbour Bridge, the Notre Dame Cathedral and between the Twin Towers of the World Trade Center. For Petit, “impossible is a human invention,” as he illustrated in his dynamic TED Talk from 2012.

To close out the episode, Petit wonderfully encapsulates the essence of all 4 TED speakers featured on this episode and hundreds of others testing the limits of science, language and humanity:

“Certainly to enter a world of terror you should not be pushed. You should be called by someone, you should be curious; you should have the heart of an explorer.”

Radio 4′s brilliant brain season now being scattered

BBC Radio 4's Brain Season is in full swing, which, in typical BBC fashion, is both brilliantly conceived and chaotically scattered over their webpages like a drunken farmer chasing birds off his field with a seed planter.

A good place to start is the brain season blog post which lists all the programmes in the season and links to their programme page and separate podcast page (if one exists). It may or may not be being updated as new material comes online.

Probably the best of the season is the History of the Brain series of which five of the ten programmes have been broadcast at the time of writing and which are all available on a single permanent podcast page.

You could go to the separate and unlinked programme information page that has a few more details and the streamed audio but I’d advise against it as it’ll only encourage them.

The one-off Mind Myths and Life Scientific programmes, the latter featuring neuroscientist Colin Blakemore, have to be downloaded from their respective podcast pages (here and here) but if you read try the page months after the broadcast date you’ll have to click ‘Show all episodes’ and scroll down to find the episode from the entire list.

The awesome looking programme The Lobotomists apparently won’t be released as a podcast at all, so unless you live in the UK and can catch it on the streaming service within the next two weeks, you’ll have to stick up your arse.

We have no idea where the similarly awesome looking series Brain Culture: Neuroscience and Society will turn up after its first broadcast on November 15th. Probably the B-side of a rare 1973 James Brown recording that has only recently become available after copies were found in the basement of the original recording studio.

Radio 4 also has a page with interviews and profiles of some of the scientists featured in the series but you can’t find out which are specifically linked to the brain season so you’ll have to…

Hang on a minute. GET ORFF MOY LAAAND YOU BLEEDIN’ BURDS!
