    But we will get designer babies eventually right? I want a glowing toddler damn it

    Does anyone else think that experimenting with embryos is the same as experimenting on people? What happened to the embrios after they where studied? Merely discarded? That may not look human to the naked eye, but that doesn't mean it isn't one. I love science, but human rights should not be violated in its name

    Why do we talk about "designer babies" and not "designed babies"? When I hear the former, I can't help but see a smug baby with a tiny mustache, a weird haircut, pinched mouth, trying to prove me their scrambled mess of a garbage-made clothing is art worth millions.

    With sickle cell anemia, this w would be a big help to myself and others like me At least if anything for the future generation.

    Why can't we use retro viruses as vectors since they can easily get into the DNA ? Is there no way to to weaken e.g HIV then put in the gene we want and change the mismatch that causes sickle cell anemia?

    We need to panic! If we don't we're failing our 24 hour news cycle system. Panic! Panic! And especially be fearful of Science. Or anyone with any kind of advanced education. Are we going to ignore all the scientific conspiracies? Climate Change. Vaccinations. Evolution. Moon landings. Please people ... you're not paying attention! Science, education, etc. is bad. And we need to acknowledge that! Anyone remember them being exposed here? www.cc.com/video-clips/x1h7ku/the-daily-show-with-jon-stewart-weathering-fights---science--what-s-it-up-to-

  • Christopher Mockford

    My sister died exactly 18 years ago from hypertrophic cardiomyopathy. I don't want that gene continued to be passed on, and am not sure which side it was inherited from, not knowing whether my surviving sister or I have passed it on. I also have a friend who was diagnosed with it, but has survived into adulthood and has two daughters, who hopefully don't have it. I'm more than ready and willing to modify my genes to not pass on any bad genes.

    • Kody Ballard
      Kody Ballard 2 days ago

      Just A Person the fact that there's no proof of any existence of God, is proof he doesn't exist, I could say that there is a giant fat sky poodle who created the earth but that a anorexic elephant cat created the rest of the world, and I'd be completely accurate in saying that because as you said "there is no reliable proof for or against [my fat sky poodle and my anorexic elephant cat], so you cannot prove or disprove the existence of [my fat sky poodle and my anorexic elephant cat]"
      ironic how you change god to anything else and that argument sounds just plain stupid......... maybe because there is no fat sky poodle and there is no "god"
      as for reliable proof against god, there's the fact of Dinosaurs existing millions of years before humans, evolution, and the fact that we've dated the planet and found that it's much older then what the Bible said it is

    Since we are all pro science here and we watch this channel to learn more about science, I have questions. What happens to the embryos from the trials? Do they become "less perfect" lab grown babies or are they disposed of in biohazardous waste bins? Is it against the hippocratic oath to grow these babies when they will most likely live a shortened lifespan? What are the morals and ethics at hand for human interference to dna on the molecular level beyond what artificial selection could have ever done?

    This is messed up.what do the researchers do with all the human beings used for their experiments?

    • Kody Ballard
      Kody Ballard 4 days ago

      APE KONG GAMER and to answer your earlier question, no it's not messed up, two people donated dna for scientific research, all cells are "alive", so the concept that when a egg and sperm meet they then become alive is false all you did was create a complete(as in all 23 chromosomes) cell than will then begin to divide and replicate, embryo cells at the stage the research was done at aren't human beings just human cells

    • Kody Ballard
      Kody Ballard 4 days ago

      APE KONG GAMER pretty sure I know what happens hence the Microbiology degree on my wall, these fertilized eggs aren't human beings yet, at this point there literally nothing more then a couple cells dividing rapidly to form cellular mass which then begins to develop organs and organs systems and eventually is born as a human being at the embryo stage there nothing more then cells

      APE KONG GAMER 4 days ago

      Kody Ballard i suggest that you google what happens when an egg is fertilized

    • Kody Ballard

      APE KONG GAMER 4 days ago

      Tdangerously somebody jerked off and somebody donated their eggs. when sperm meets an egg the egg becomes fertilized thus creating life. The life of these fertilized eggs is terminated once the scientists are done with them. You don't find that messed up?

    I wonder if scientists can figure how to get the DNA to accept the donor DNA during repair, that would be interesting. Maybe they can "CRISPR/cas9 it" (donor DNA) into the egg cell first somehow, before inserting the sperm and cas9 enzyme. Then we can utilize the mechanism that the sperm and egg cells naturally use to repair DNA in a different way. Wish I could fully grasp the science behind this; I think it's so interesting!

  • Jesus Christ is coming! Repent & Believe the Gospel

    Hello, friends.
    I was angry all the time, I was addicted to porn, I was a homosexual, I hated people and hated my family especially. I was depressed and I just wanted to die.

    Jesus Christ rescued me. Literally. He washed away my sins and made me new. I am redeemed by His Blood! Hallelujah! I feel happy now, I have True Peace from the Prince of Peace! This is why I am preaching. I have experienced something very real. Jesus loves us, friends. Repent of your sins and put your faith in Him! He will help you, trust Him. He is not angry at you, He is waiting on you to call upon Him. You will be saved! He is forgiving and merciful. He will forgive you and help you if you seek Him with your whole heart.
    He is not expecting you to clean yourself, He will do it.

    Time is short, and Jesus Christ is coming soon, friends. Please make this moment you call upon Him, you don't have to say a complicated prayer, just be real with Him. Ask for forgiveness of your sins, believe He died and rose from the dead 3 days later, for the forgiveness of sins. Ask Him to help you with whatever your sins are and whatever you are going through, He will help you. I cannot stress it enough.

    You might not have another chance to do it, so please make it today if you haven't already. It is a dangerous and eternal thing if you die without Jesus. He will not let you enter hell if you have Him before you die. He is Our Mighty Savior! Hallelujah!

  • Low Key
    Low Key 5 days ago

    I'm curious about something: could all these 'diseases' actually be mutations that have, in some way unknown to us, given us an advantage at some point during our evolution and could, in the future, protect us against whatever the environment throws at us? For instance, what if autism wasn't a disorder in some situations, but was rather an evolved advantage that suited a particular situation in our collective past? By editing out these mutations, maybe we're actually protecting ourselves from our protections?

    Progress in genetic engineering is more hope that we, as a species, will survive the effect that the act of saving people from illnesses with medical treatments, is having on our gene pool. Good thing that we know many ways that DNA is destroyed, and how it can be preserved. So if, in hundreds of years from now, we have only just perfected and made pratical, genetic engineering for near everyone, then we'll be able to introduce healthy DNA from a time period where modern medicine was only just beginning to be effective at preventing death. Because, it still wasn't that long ago, when doctors scoffed at the idea of washing their hands before helping to deliver a baby.
