Post-reading
Let’s read a news about genetically edited babies
A Chinese researcher, He Jiankui, shocked the world two weeks ago when he revealed that the world’s first genetically edited babies had been born. Jiankui claimed to have edited embryos(胚胎) before implanting(移植) them into the mother.
Jiankui used a easy gene-editing technology to disrupt the gene for CCR5. He claimed that disruption of CCR5 would ensure that these babies would be protected from contracting HIV infection.
Since his bold announcement via YouTube, the scientific community at-large – both in the United States and in China – has strongly condemned this work as deeply unethical (不道德的) and dangerous.

1. The lecturer mentions that one day we will be able to create “designer babies”.
What do you think of “designer babies” Can you list its pros or cons
Post-reading
1. Designer babies can be perfectly healthy.
2. Designer babies can be stronger and cleverer.
3. Designer babies help further the cause(事業(yè)) of science.
4. Designer babies may have longer lifespan.
5. Designer babies can maintain a healthy gender ratio, the balance of males and females.
Pros
What do you think of “designer babies” Can you list its pros or cons
Cons
1. Designer babies will not be a success story all the time.
2. Designer babies can cause a rift (分歧,裂縫) in the social balance.
3. Designer babies would be manufactured(已制成的) so
there would be no individuality (個(gè)性).
What do you think of “designer babies” Can you list its pros or cons
2. What controls can we put in place to make sure that genome editing will work to our advantage
Post-reading
Tips: Governments ......
Global organizations ......
The public ......
How What ......
Governments around the world should work together to make laws and regulations about when genome editing can and cannot be used.
First, these laws and regulations should cover various aspects of genome editing, such as ethical issues and security, and they may have to be introduced at multiple levels—global, national and even regional.
Second, genome editing equipment needs to be strictly controlled so that it does not get into the wrong hands.
Finally, governments, scientists, stakeholders(利益相關(guān)者) and the public need to work together to enforce(實(shí)施,執(zhí)行) appropriate usage of genome editing.
Summary
Genome editing is one of the greatest inventions in the history of science , and we should put appropriate controls in place to make sure that genome editing will work to our advantage.
Thank you.
