First, let me tell you how smart I am. So smart. My fifth-grade teacher said I was gifted in mathematics and, looking back, I have to admit that she was right. I’ve properly grasped the character of metaphysics as trope nominalism, and I can tell you that time exists, but that it can’t be integrated into a fundamental equation. I’m also street-smart. Most of the things that other people say are only partially true. And I can tell.
Researchers succeed in deleting key genes from ants, significantly modifying their behavior.
A staple of bad science fiction, mutant ants have been more of a figment of imagination rather than scientific reality. We’ve genetically altered mice and fruit flies, but growing mutant ants has eluded scientists due to the complex life cycle of the little critters. Now two teams announced that they managed to edit out certain genes from lab ants, altering their behavior.
Has CRISPR co-creator Jennifer Doudna invented the Pandora's Box of genetic engineering, or can CRISPR be used for the forces of good?
Jennifer Doudna was a pioneer of CRISPR, which is a gene-editing technology that is being increasingly studied and used across the world. Jennifer relates the genesis of CRISPR to us and explains the pros and cons of giving birth to such a potentially world changing process. On the positive side, she tells us how scientists are already combining her technology with stem cell research to potentially rid the world of sickle cell anemia. On the negative side, she describes a vivid nightmare she had early on in the process wherein she meets Hitler with a pig nose—a David Lynch-ian vision that represents the negative possibilities of what could happen if CRISPR falls into the wrong hands. While the Pig Hitler scenario is a lot less likely to actually happen, Jennifer understands the duality of her role in CRISPR's creation.
A "forbidden research" conference at MIT tackles areas of science constrained by ethical, cultural and institutional restrictions.
Has technology advanced enough that we could stitch together body parts and reanimate the dead? Bill Nye one-ups that old-school Frankenstein vision with newer (and cooler) scientific possibilities.
This week on Tuesday’s With Bill, Lauren from Tennessee wants to know whether it would be possible to assemble different body parts and reanimate them in the style of Frankenstein’s monster. Stitching together parts and inserting consciousness is likely not possible, says Nye – the closest future theory to it is the singularity, when AI gets as intricate and sophisticated as the human brain, and we’re able to upload our consciousness into it and live for as long as we keep the batteries charged. Nye has his doubts about that, however. What he is optimistic – and realistic – about is developing technology that in the next 50 years or so will allow us to regenerate our own body parts from stem cells. In our lifetime perhaps we could grow a new pancreas or a liver segment for our own transplant. Connected moving tissue like hands and fingers are much further into the future. CRISPR is another incredible technology that’s only in its infancy. It’s a genetic engineering cut-and-paste methods that allows genes to be manipulated to basic desires. Once that technology is developed, we may be able to create genetic supermen and women in the womb, and it likely has applications beyond what we can currently imagine. The potential for what humans can create is immense, and will be a lot sleeker looking than a flesh and thread patchwork a la Frankenstein. Bill Nye's most recent book is Unstoppable: Harnessing Science to Change the World.
