On November 26, Jiankui He, an associate professor at South University of Science and Technology of China, announced to the world that his lab has created the world's first genetically edited twin babies. As a result, it's revolutionizing scientific research and raising high hopes for major breakthroughs, including preventing and treating many diseases.
Academics in the West were quick to condemn such research on humans. When those prohibitions fall - as today's announcement from the Second International Summit on Human Genome Editing suggests they will - what ethical guideposts or moral norms should replace them?
The outcry by Chinese scientists from top universities - such as Peking University and Tsinghua University in Beijing and Fudan University in Shanghai - and many members of the prestigious Chinese Academy of Sciences, including some at universities in the US, United Kingdom, Germany and Singapore, is highly unusual in China.
In an open letter, more than 300 Chinese scientists raised 10 questions for He and his team related to safety, effectiveness and objective of the research, and whether he has concealed other related experiments from the public, China Daily reported.
For their research, He and his colleagues say they used CRISPR to make changes in one-day old embryos in a gene called CCR5.
If the claim is verified, genetic engineers have already likened the birth to that of the first baby born through IVF. "We believe ethics are on our side of history", says He, who calls the term "designer babies" an epithet. We need to close it before it is too late.
He is scheduled to speak at the summit on gene editing on Wednesday, but organizers were unsure whether he planned to discuss his experiment.
Li Jinsong, a researcher from the Institute of Biochemistry and Cell Biology of the Chinese Academy of Sciences, has said the research is "unbelievable, totally unacceptable".
He Jiankui, an associate professor of biology at SuSTech, was previously at Rice University, Houston, and Stanford University in the United States before returning under China's "Thousand Talents" programme created to lure top scientists home with generous financial benefits.
Hundreds of scientists, both in China and around the world, swiftly condemned his claims. The school placed He on leave and said they'd be investigating the work conducted in the lab.
However, the university told media outlets He's work "seriously violated academic ethics and standards".

It's clear he could not care less'. "Don't give this disgrace of a man five more years of driving our NHS into the ground". Boris Johnson has apologised after a four-year-old boy was forced to sleep on a hospital floor due to a lack of beds.

She said: " Jagged Edge defended Miss Pam because it's wrong, we can't leave this girl's mother". "That meeting never happened". Jagged Edge is a R&B group that consisted of Brian Casey , Brandon Casey, Richard Wingo and Kyle Norman .
Harbour Air flies the world's first electric seaplane
Harbour Air covers 12 routes and operates about 30,000 flights a year between Vancouver, Victoria, Seattle and other locations. Ganzarski said the technology would mean significant cost savings for airlines - not to mention zero emissions.
Scientists have been abuzz with excitement ever since it became clear that CRISPR would unlock a new world of powerful gene editing techniques.
"This experiment exposes healthy normal children to risks of gene editing for no real necessary benefit".
Zhang said he was "deeply concerned" that the Chinese project was undertaken in secrecy. However, there are concerns about safety and ethics.
His statement has not been confirmed, but if true breaks tight rules around the use of gene editing in humans.
He sought and received approval for his project from Shenzhen Harmonicare Women's and Children's Hospital, which is not one of the four hospitals that He said provided embryos for his research or the pregnancy attempts.
The genetically-modified twin sisters were not born at the hospital, health officials said.
The case shows "there has been a failure of self-regulation by the scientific community" and said the conference committee would meet and issue a statement on Thursday about the future of the field, Baltimore said.
He said the parents involved declined to be identified or interviewed, and he would not say where they live or where the work was done.
"The scientific understanding and technical requirements for clinical practice remain too uncertain and the risks too great to permit clinical trials of germline editing at this time".
China had earlier withdrawn from the summit, according to the organisers, prompting speculation that it did not wish to be in the spotlight over ethical issues and general research transparency.
"Gene editing itself is experimental and is still associated with off-target mutations, capable of causing genetic problems early and later in life, including the development of cancer", he told the BBC. Using the new tool on sperm, eggs, or embryos means descendants will also inherit the changes. He Jiankui, the scientist who led the effort, announced the outcome in a promotional video on YouTube Sunday, just days ahead of participating in an global conference on human genome editing scheduled to take place this week in Hong Kong.
