What dinosaur traits are missing from an ostrich? The ostrich has a toothless beak, but there are mutations that cause teeth and claws to come back to their mouth and limbs. You need to replace the feathers with scales, but there are no feathers on their legs and feet, so you just need to make its whole body like its legs are.

The rewards for biotechnology are tremendous - to solve disease, eliminate poverty, age gracefully. It sounds so much cooler than Facebook.

Making new petroleum should be as simple and straightforward as brewing beer.

The first thing you have to do is to sequence the Neanderthal genome, and that has actually been done. The next step would be to chop this genome up into, say, 10,000 chunks and then... assemble all the chunks in a human stem cell, which would enable you to finally create a Neanderthal clone.

As part of our dedication to safety engineering in biology, we're trying to get better at creating physically contained test systems to develop something that eventually will be so biologically contained that we won't need physical containment anymore.

Reversal of ageing is high on my list of things to do, and not just because I'm getting old.

If society becomes comfortable with cloning and sees value in true human diversity, then the whole Neanderthal creature itself could be cloned by a surrogate mother chimp - or by an extremely adventurous female human.

I always loved computers - it's something inside you.

I think my original inspiration came from just natural curiosity about science and math and biology. In particular, I would say that, as I matured, it became more a feeling of trying to avoid the waste that occurs in the world where we have 6.5 billion minds. If you're a computer scientist, you can think of them as supercomputers.

My laboratory and my obsession is about safety and building/engineering safety. It's not just a matter of saying we want the world to be safer; we have to create technology.

Very often, as I wander through life, I'll get that old feeling that I've come back from the future, and I'm living in the past. And it's a really horrible feeling.

I'll drop something for a while, a year or maybe several years, and then pick it up again. I think that's the way successful innovators work. They keep juggling ideas, keeping them in the air, in the back of their mind, to inspire them or enable new recombinations.

Every cell in our body, whether it's a bacterial cell or a human cell, has a genome. You can extract that genome - it's kind of like a linear tape - and you can read it by a variety of methods. Similarly, like a string of letters that you can read, you can also change it. You can write, you can edit it, and then you can put it back in the cell.
