WORLD FIRST! Genetically modified human embryos!

Genetically modified human embryos. Is that going too far? It seems that support has risen in favour of using genetic modification to cure genetic diseases. I'm sure you've heard by now what I'm talking about, a team in China used a method called CRISPR/Cas9 to edit the genome of human embryos. Watch this video for a better understanding of how CRISPR/Cas9 works (and heck, the video's pretty).


The embryos were donated and permission was given for them to be used for this purpose, and the study complied with ethical regulations. There are a lot of people out there who don't agree we should be genetically modifying anything, but they tend to be people who don't know much about it and they assume it's bad because big bad money driven companies are using it for their own benefit. What do you think? Should we be doing this in human cells? Being capable of doing this also raises another ethical question - designer babies. Will it get that far? Could it be regulated so that it's only used against diseases? What other potential problems will come up though? There are so many more questions that need to be answered, and for now, I think we're doing the right thing, we're not getting ahead of ourselves yet.

25th April was World DNA Day to celebrate when Watson, Crick, and Franklin, and a few other men, published papers on the structure of DNA. It was also World Penguin Day so fun fact; penguins are black and white like that for camouflage in the water, from above they blend it with the dark water, and from underneath in the water, it just looks like a reflection of the sun!

Hope you found this interesting! Let me know if you'd like to see more science here :)

  1. I found this very interesting! As someone with a genetic disease I'm 100% for it if it'll stop people from suffering. If it get used to ensure a girl/boy, blue eyes/brown eyes etc I don't really agree with that but for medical purposes I think it's brilliant if it actually works xx

  2. I'd say the process is so new that it may irk people the wrong way. However, I can understand the use of modifying an embryo solely for health purposes. Obviously, the goal would be quality of life long term. I wouldn't agree with it if people were using it to create like the prettiest baby, altering genes for cosmetic sake. :]

  3. I watch too much Orphan Black that I am soooooo afraid it would turn bad. But genetic modification to prevent disease sounds good. There just need to be strict regulations to prevent this science into profit machine by making 'by-request' modifications.

    Oh science. Never ceases to amaze me.

  4. I've actually been researching "designer babies" as part of my technologies class! Did you know that a place in LA actually opened the "designer baby" debate in 2009? A clinic actually said that it was possible and started gathering clients. Crazy, right?

  5. The designer baby thing does totally freak me out, but so many people are against it entirely and I don't understand why if it will help people! xo

  6. Yeh designer baby talk freaks me out! So many people are afraid of science because they don't understand it.There are magazines and articles though that explain things in a way everyone could understand so it frustrates me when people don't even try to understand it, and then complain about it with false facts! I hope that progress is made and we can start making positive differences to peoples health :) xo

  7. Omg, I've just watched the first ep of Orphan Black!! If it's related to THIS then I am excited! Anything sci-fi I freaking love haha. Yes, if it was in the wrong hands it wouldn't be great. That's one reason why so many people are wary of GMOs like corn and other foods, because instead of it being used to provide in countries who need it, big businesses are exploiting it to get richer :( xo

  8. Oh wow what a fascinating class! What have you found out about it? :) that sounds so scary :/ ewwww! Even if it's possible it freaks me out haha, I mean curing disease is amazing but choosing eye colour?! It would reduce the diversity as well which isn't good for species and populations haha :/ xo
