Health Desk-March 14, 2019: Scientists have recently called for a ban on research to "re-engineer the human species" for the next five years.
The scientists write in the journal Nature said, "major speed bumps" needed to be put in front of such research.
The US National Institutes of Health said a ban should start immediately, but others have criticised the idea.
It all comes down to the ability of scientists to manipulate DNA.
Usually DNA contains the instructions for building and running the human body including traits such as height, hair colour and risk of diseases.
A relatively new tool called CRISPR has allowed scientists to quickly and cheaply alter DNA and has led to an explosion in gene editing technologies.
They have the potential to be used to "re-engineer" us by correcting faults in DNA that cause disease or even to enhance the human body.
