ANTS HAVE ALGORITHMS

Iain Couzin
[3.11.08]

"Another example that we've been investigating arehuge swarms of Mormon crickets. If you look at these swarms, all of the individuals are marching in the same direction, and it looks like cooperative behavior. Perhaps they have come to a collective decision to move from one place to another. We investigated this collective decision, and what really makes this system work in the case of the Mormon cricket is cannibalism."

ENGINEERING BIOLOGY

Drew Endy
[2.17.08]

"The only thing that hasn't been engineered are the living things, ourselves. Again, what's the consequence of doing that at scale? Biotechnology is 30 years old; it's a young adult. Most of the work is still to come, but how do we actually do it? Let's not talk about it, let's actually go do it, and then let's deal with the consequences in terms of how this is going to change ourselves, how the biosecurity framework needs to recognize that it's not going to be nation-state driven work necessarily, how an ownership sharing and innovation framework needs to be developed that moves beyond patent-based intellectual property and recognizes that the information defining the genetic material's going to be more important than the stuff itself and so you might transition away from patents to copyright and so on and so forth.."

LIFE: A GENE-CENTRIC VIEW

Edge @ DLD
Richard Dawkins, J. Craig Venter, John Brockman
[1.23.08]

"It's not everyday you have Richard Dawkins and Craig Venter on a stage talking for an hour about "Life: A Gene-Centric View". That it occured in Germany, where the culture has been resistant to open discussion of genetics, and at DLD, the Digital, Life, Design conference organized by Hubert Burda Media in Munich, a high-level event for the digital elite — the movers and shakers of the Internet — was particularly interesting. This event was a continuation of the Edge "Life: What a Concept!" meeting in August, 2008."

SOME LIKE IT HOT

Steve Jones
[10.14.07]

"If you look at people who sequence DNA—the original DNA sequences, which is a wonderful piece of work of course—in Watson's own DNA sequence—it's a very platonic view of what life is all about. You take a human being, an exemple, an exemplar, J.D. Watson. You've got his DNA. That's the end of the story.??"But of course it isn't like that. If there wasn't difference, then we wouldn't have genetics. We wouldn't have evolution. We'd all be stuck in the primeval slime. Genetics has moved on to think about difference. Why are people, why are snails, so different from each other?"

DO WOMEN HAVE BETTER EMPATHY THAN MEN?

Simon Baron-Cohen
[10.14.07]

"It turns out that when you test newborn babies—this experiment was done at the age of 24 hours old, where we had 100 babies who were tested looking at two kinds of objects—a human face and a mechanical mobile. And they were filmed for how long they looked at each of these two objects. What you can see here is that on the first day of life, we had more boys than girls looking for longer at the mechanical mobile and more girls than boys looking at the face. So you can see that these differences when they emerge, first of all they seem to emerge very early—at birth—suggesting that there may be a biological component to a sex difference in, in this case, interest in faces; and secondly, they don't apply to all males or all females, these differences emerge as statistical trends when you compare groups."

HOW OUR LIMBS ARE PATTERNED LIKE THE FRENCH FLAG

Lewis Wolpert
[10.14.07]

"I've spoken to these eggs many times and they make it quite clear...they are not a human being."


 

A COOPERATIVE FORAGING EXPERIMENT: LESSONS FROM ANTS

Seirian Sumner
[10.14.07]

"You are a leaf-cutting ant from South America. You will compete against the humans across the aisle in a foraging activity. You're task is to collect as much forage as possible. There's a reason ants are so successful. They're disciplined. They follow a series of rules. The first rule is no talking. Ants can't talk so you can't talk. The second rule is no gestures, facial or otherwise. And to make sure you can't use facial expressions we're going to put a paper bag on your head. The third rule is 'Ant walking'. ...


 

Seth Lloyd—LIFE: WHAT A CONCEPT!

An Edge Special Event at Eastover Farm
Seth Lloyd
[8.27.07]

"If you program a computer at random, it will start producing other computers, other ways of computing, other more complicated, composite ways of computing. And here is where life shows up. Because the universe is already computing from the very beginning when it starts, starting from the Big Bang, as soon as elementary particles show up. Then it starts exploring — I'm sorry to have to use anthropomorphic language about this, I'm not imputing any kind of actual intent to the universe as a whole, but I have to use it for this to describe it — it starts to explore other ways of computing."

George Church—LIFE: WHAT A CONCEPT!

George Church
[8.27.07]

"Many of the people here worry about what life is, but maybe in a slightly more general way, not just ribosomes, but inorganic life. Would we know it if we saw it? It's important as we go and discover other worlds, as we start creating more complicated robots, and so forth, to know, where do we draw the line?"
