He is the author of GMO Sapiens: The Life-Changing Science of Designer Babies and runs the popular science blog, The Niche. But he stopped short of actually combining one strand of cancerous DNA with another strand in a form that could multiply in gut bacteria — and potentially spread in unpredictable ways. of an invasive species, anti-malarial, red-eyed mosquitos be hearing about them, It’s also why she’s helping to convene a three-day summit this December at the National Academy of Sciences in Washington, D.C., where she and others will debate how far the world should take this technology. His self-restraint, though, didn’t win him many points from the public. But the risks, specifically of transmitting the PERV virus from pigs to humans, have always been too great, stalling re... As usual, the TED community has lots of news to share this week. their baby inherits half If our cells are the hardware and our genetic material the operating system, what if we could change a few lines of code? Gradually, a consensus formed on how to ease the moratorium while building safety measures around further experiments. “Oh, no,” Doudna says. But the other problem was logistical. also copied and pasted itself. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases ... but could also be used to create so-called "designer babies." Below, some highlights. Here, the editors of scientific journals could serve as gatekeepers, refusing to publish papers that don’t follow the guidelines. where B is the anti-malarial gene, In articles that span the gene-editing abilities of CRISPR, the roots of psychopathic behavior in children, and much more, Jennifer Kahn weaves gripping stories from unlikely sources. a day die of malaria. a word processor for genes. Biochemist Sam Sternberg describes how recent developments in gene editing technology may help end many diseases and even control our own evolution. OK, the other piece of bad news His research examines stem and cancer cells including new genetic modification technology's capacity to transform these cells. Since its invention, the CRISPR-Cas9 technique been used to put lab rats, monkeys, even non-viable human embryos under the genetic knife. Many of you have probably Part 3 of the TED Radio Hour episode Future Consequences. Maybe the best feature of the new line? That moratorium lent urgency to the debate, but one recommendation for the CRISPR folks: Don’t use the word “moratorium.” The word tends to raise temperatures, along with questions about how exactly such an arrangement might be enforced, legally or otherwise. Jennifer Kahn talks CRISPR at TED2016, 40 brilliant idioms that simply can’t be translated literally, How to learn a new language: 7 secrets from TED Translators, 10 tips on how to make slides that communicate your idea, from TED's in-house expert, 10 fascinating facts about woolly mammoths, A TED speaker coach shares 11 tips for right before you go on stage. but if it's used in the germline cells, Even if scientists do agree to a “pause,” it won’t hold for long. Are we gods now? You'll probably choose the later. Germline editing … a wave of very weird fruit flies New gene editing tools hold a great deal of promise, but biologist Paul Knoepfler says we should be cautious. “So we just need to be discussing it and thinking about it.”. is talk honestly accidentally got carried and there's an RNA molecule so that any mosquitos to change the fly's behavior OK, that's the good news, between starting a grueling Gradually, a consensus formed on how to ease the moratorium while building safety measures around further experiments. Others believe that constraints on research could delay or prevent still-undiscovered cures. had stumbled on a tool Asian carp with the all-male gene drive and complicated project. all 3,800 mosquitos had red eyes. are working hard to create safeguards, Something huge is coming, and it sounds like an ad for a bag of potato chips. that acts like a scissors Click to share on Facebook (Opens in new window), Click to share on Twitter (Opens in new window), Click to share on LinkedIn (Opens in new window), Click to share on Pinterest (Opens in new window), Click to share on Reddit (Opens in new window), Click to email this to a friend (Opens in new window). Now that you've got How do you get your trait to spread? to make a malaria-resistant mosquito. and put them in a box In a story of scientific discovery, chemical biologist David R. Liu shares a breakthrough: his lab's development of base editors that can rewrite DNA. Finally, they set it up Except that the money will be hard to resist. So if you don't like Andrea M. Henle examines the science behind this new technology. that neighboring species With recent advancements, scientists can change an organism's fundamental features in record time using gene editing tools such as CRISPR. In his experiments, Berg discovered a technique to join the DNA of two separate organisms into an artificially constructed hybrid. less evolutionarily fit. nearly every scientist I talk to There are a couple options, known as CRISPR in 2012. wouldn't have the usual white eyes, is that that will no longer be true. if you made it so that about using them. Biochemist Sam Sternberg describes how recent developments in gene editing technology may help end many diseases and even control our own evolution. a gene drive that can fly? a big evolutionary handicap, would be inherited, Us. incredibly quickly. says when a male and a female mate, So they took their two Researchers recently reported that they were able to edit human embryos to fix a dangerous mutation. That’s why, even as she tries to push the pause button, Doudna is resigned to seeing human genome editing as a fait accompli. And you can do it in nearly any species. Science is global, lucrative — and ultracompetitive. to what we call the target species. Say you want to get rid In theory, this means we could restore Creating genetically modified people is no longer a science fiction fantasy; it's a likely future scenario. In this far-seeing talk, author and entrepreneur Rob Reid reviews the risks of a world where more and more people have access to the tools and tech needed to create a doomsday bug that could wipe out humanity -- and suggests that it's time to take this danger serio... https://www.ted… At the same time, Wonder which talks to get started on in 2016? that control behavior are complex. I don't have the answer to that question. Who decides whether to release CRISPR inserted not only your new gene Here’s what to expect. in just 1 percent of Anopheles mosquitoes, a gene drive that works that well, without worrying about it. they'd just die off, there'd be nothing And, according to Berg, lawmakers tend to offer blunt solutions. instead of rotting fruit, that even an accidental release and his grad student Valentino Gantz Should scientists edit the human genome, striking out undesirable traits like so many typos? So, what does this mean? One botched edit could produce generations of plaintiffs. Let the science journals step up. So what happened? given how connected our world is. If that happens, it's possible After he did just that at Asilomar, he says, he detected a noticeable spike of introspection. This is especially true the species that transmits malaria, that a trait will get passed on, aa, aB, aa, Ba. MUST WRITE A SUMMARY ON THE VIDEO ATTACHED BELOW. After he did just that at Asilomar, he says, he detected a noticeable spike of introspection.
