Michio Kaku: Genetic and digital immortality are within reach

Technology may soon grant us immortality, in a sense. Here's how.

MICHIO KAKU: The rate at which we are learning about longevity Gives one pause. It makes you realize that perhaps digital and genetic immortality are Within reach. Already, in Silicon Valley, there are companies which, for a price, will digitize everything known about you your credit card transactions, your emails, Instagrams. Everything known about you can be digitized. And we have something called the Connectome Project, which will map the pathways of the entire human brain all your memories, all your quirks, personalities, everything digitized. And we'll put it on a disk. And for the most part, we'll put it in a library. Today, you go to the library, and you take a book out About Winston Churchill. In the future, you'll go to the library and talk to Winston Churchill, because all his speeches, his mannerisms, his memories, his letters, Have been digitized. I would love to talk to Einstein. I would love to talk to him, even if it's a computer program that has digitized everything known about him his work, his writings, His speeches, everything, and a holographic image, so that I can talk to him. And one day, we might be digitized, as well. We'll be able to talk to our great-great-great-great-great grandkids, and they'll be able to talk to their great-great-great-great-great Ancestors, as well. Because we become immortal. Not only that, but we're now beginning to isolate the genes which control the aging process. First of all, let's take a car. Where does aging take place in a car? Aging takes place in the engine. Why? That's where you have moving parts and combustion. Well, where, in the cell, do we have the power house of a cell? Mitochondria. Bingo, we now know where most of the errors build up in a cell. And with CRISPR technology, we may be able to edit out the errors that build up and extend the human lifespan. For example, a mouse can live to be about roughly two years of age, and then it dies of old age. But the Greenland shark can live to be over 400 years of age. And that's just not hearsay. By looking at the eyeball of the Greenland shark, it adds layers at a very precise rate in the eye. By analyzing and counting the layers, we see that the Greenland shark can live almost 500 years in age. So in other words, genetically speaking, it may be possible to extend the human lifespan. So genetic and biological immortality are definitely in the cards.
  • Through the Connectome Project we may soon be able to map the pathways of the entire human brain, including memories, and create computer programs that evoke the person the digitization is stemmed from.
  • We age because errors build up in our cells — mitochondria to be exact.
  • With CRISPR technology we may soon be able to edit out errors that build up as we age, and extend the human lifespan.

Tyranny comes home: How the 'boomerang effect' impacts civilian life in the U.S.

When it comes to foreign intervention, we often overlook the practices that creep into life back home.

Videos
  • Methods used in foreign intervention often resurface domestically, whether that's in the form of skills or technology.
  • University of Tampa professor Abigail Blanco calls this the boomerang effect. It's a consequence not often thought about when we discuss foreign intervention.
  • The three channels to consider when examining the boomerang effect include human capital in the form of skills, administrative dynamics, and physical capital in the form of tools and technology.

  • Many readers buy books with every intention of reading them only to let them linger on the shelf.
  • Statistician Nassim Nicholas Taleb believes surrounding ourselves with unread books enriches our lives as they remind us of all we don't know.
  • The Japanese call this practice tsundoku, and it may provide lasting benefits.

Listen: Scientists recreate voice of 3,000-year-old Egyptian mummy

Scientists used CT scanning and 3D-printing technology to recreate the voice of Nesyamun, an ancient Egyptian priest.

Surprising Science
  • Scientists printed a 3D replica of the vocal tract of Nesyamun, an Egyptian priest whose mummified corpse has been on display in the UK for two centuries.
  • With the help of an electronic device, the reproduced voice is able to "speak" a vowel noise.
  • The team behind the "Voices of the Past" project suggest reproducing ancient voices could make museum experiences more dynamic.
