Chinese Scientist Claims to Have Created the World’s First Genetically Edited Babies

Chinese researcher He Jiankui recently shocked the entire world after revealing that he had altered the DNA of twin girl before birth, to make them immune to the HIV virus and AIDS. If his claims prove to be true, these twins would be the world’s first genetically-edited babies.

Professor He revealed his controversial genetic editing work earlier this week. In a video posted on YouTube, he claims to have used gene-editing tools to eliminate a gene called CCR5 in order to make a pair of twin girls, called Lulu and Nana, resistant to the HIV virus, should they ever come in contact with it. Speaking at a genome summit in Hong Kong, on Wednesday, the Chinese scientist defended his work and talked about the stigma attached to HIV/Aids in China. However, many of his peers believe that He Jiankui has gone too far, warning that meddling with the genome of an embryo could cause long-term problems not only for the individual, but entire future generations.

The Strange Case of a Family That Doesn’t Feel Pain

An entire Italian family suffer from a strange genetic mutation that makes them almost completely immune to pain. The condition is so rare that scientists have named it ‘The Marsili Syndrome’, after the family.

Letizia Marsili, 52, became aware of her immunity to pain in early childhood when she didn’t experience any particular sensation from burns or fractures. Five other members of her family, spanning at least three generations, also share this rare genetic anomaly that makes impervious to pain situations where an average person would require an anesthetic. The Marsilis have become the focus of researchers hoping to discover how their mutation works, in the hopes of developing new ways to treat pain.
