Dr. F's Random Thoughts

Hello there bloggies, and welcome to this week’s Science Sunday! Hope you all had a lovely weekend!

Recently, there was a report from an institution in China using CRISPR/Cas9 technology to directly edit human embryos. There are loads of blurbs out there as well including this one from Nature (http://www.nature.com/news/chinese-scientists-genetically-modify-human-embryos-1.17378?WT.mc_id=FBK_NatureNews).

What this means is that these scientists cut out a specific part of these embryos’ DNA and insert a DNA sequence they want. This is the first application of this genome editing technology to human embryos. CRISPR/Cas9 has been used in model organisms like mice in order to specifically knock-out (i.e. remove) a certain gene and/or to introduce a new gene/mutation. It has been a powerful tool to examine the function of numerous genes.

Now, these human embryos had zero chance of being implanted and viable. But, the fact that these scientists completed these experiments and the troubles…
