WHAT DO ANIMALS WANT?

Conversation:
[10.31.12]
Topic:

"Whatever anybody says, I feel that the hard problem of consciousness is still very hard, and to try and rest your ethical case on proving something that has baffled people for years seems to me to be not good for animals. Much, much better to say let's go for something tangible, something we can measure. Are the animals healthy, do they have what they want? Then if you can show that, then that's a much, much better basis for making your decisions."

 

BRAINS PLUS BRAWN

Conversation:
[10.17.12]
Topic:

"There are many other features in the head that help us become these exceptional long-distance walkers and runners. I became obsessed with the idea that humans evolved to run long distances, evolved to walk long distances, basically evolved to use our bodies as athletes. These traces are there in our heads along with those brains."

 

TO BRING BACK THE EXTINCT

Conversation:
[8.28.12]
Topic:

"One of the fundamental questions here is, is extinction a good thing? Is it "nature's way?" And if it's nature's way, who in the world says anyone should go about changing nature's way? If something was meant to go extinct, then who are we to screw around with it and bring it back? I don't think it's really nature's way. I think that the extinction that we've seen since man is 99.9 percent caused by man."

 

WHAT IS LIFE? A 21st CENTURY PERSPECTIVE

Conversation:
[7.12.12]
Topic:

"I was asked earlier whether the goal is to dissect what Schrödinger had spoken and written, or to present the new summary, and I always like to be forward-looking, so I won't give you a history lesson except for very briefly. I will present our findings on first on reading the genetic code, and then learning to synthesize and write the genetic code, and as many of you know, we synthesized an entire genome, booted it up to create an entirely new synthetic cell where every protein in the cell was based on the synthetic DNA code."

 

J. CRAIG VENTER: THE BIOLOGICAL-DIGITAL CONVERTER, OR, BIOLOGY AT THE SPEED OF LIGHT @ THE EDGE DINNER IN TURIN

Conversation:
[7.10.12]
Topic:

"We can now send biology at the speed of light, and this is one of the implications of our work, which we recorded two years ago making the first synthetic life form. We completely synthesized the genetic code of a cell starting with a digital code in the computer—it's the ultimate interface between computers and biology. The digital code and the genetic code have a lot in common; something Schrodinger pointed out in 1943, saying it could be something as simple as the Morse code."

 

TESTOSTERONE ON MY MIND AND IN MY BRAIN

Conversation:
[4.30.12]
Topic:

"This is a hormone that has fascinated me. It's a small molecule that seems to be doing remarkable things. The variation we see in this hormone comes from a number of different sources. One of those sources is genes; many different genes can influence how much testosterone each of us produces, and I just wanted to share with you my fascination with this hormone, because it's helping us take the science of sex differences one step further, to try to understand not whether there are sex differences, but what are the roots of those sex differences? Where are they springing from? And along the way we’re also hoping that this is going to teach us something about those neuro-developmental conditions like autism, like delayed language development, which seem to disproportionately affect boys more than girls, and potentially help us understand the causes of those conditions."

 

Rethinking "Out of Africa"

Conversation:
[11.12.11]
Topic:

"I'm thinking a lot about species concepts as applied to humans, about the "Out of Africa" model, and also looking back into Africa itself. I think the idea that modern humans originated in Africa is still a sound concept. Behaviorally and physically, we began our story there, but I've come around to thinking that it wasn't a simple origin. Twenty years ago, I would have argued that our species evolved in one place, maybe in East Africa or South Africa. There was a period of time in just one place where a small population of humans became modern, physically and behaviourally. Isolated and perhaps stressed by climate change, this drove a rapid and punctuational origin for our species. Now I don’t think it was that simple, either within or outside of Africa. "
