Amid the outcry, He was placed under police investigation, the government ordered a halt to his research work and he was fired by his Chinese university. Moreover, CRISPR remains an imperfect tool because it can lead to unwanted or 'off-target' edits, making its use in humans hugely controversial. A Chinese court on Monday sentenced the scientist who claimed to be behind the world's first gene-edited babies to three years in prison for illegal medical practice, state media reported. Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at, almost immediately after He announced his research, Some scientists have called for a global moratorium, scientists in other countries have suggested, WHO Declares the Coronavirus Outbreak a Pandemic, Disease Caused by the Novel Coronavirus Officially Has a Name: COVID-19, U.S. to Quarantine 195 Americans Evacuated from Wuhan, Researchers Rush to Test Coronavirus Vaccine in People, Synthetic Biologists Think They Can Develop a Better Coronavirus Vaccine Than Nature Could. Nothing is known publicly about the health and wellbeing of Lulu and Nana at this point. The reason isn't entirely clear, but Nielsen thinks it's probably because of an increased vulnerability to the flu. While the team targeted the right gene, they did not replicate the "Delta 32" variation required, instead creating novel edits whose effects are not clear. Even if editing worked perfectly, people without normal CCR5 genes face higher risks of getting certain other viruses, such as West Nile, and of dying from the flu. 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 U.S. presidential race is a near dead heat, this A.I. He Jiankui in a press photo in November, 2018. hide caption. © 2020 Fortune Media IP Limited. The polls are wrong. The first gene therapies were indeed deadly. But many scientists, bioethicists and advocates worry other scientists will misuse the technology prematurely. The trio hadn't obtained qualifications to work as doctors and had knowingly violated China's regulations and ethical principles, according to the court verdict, Xinhua said. The Chinese scientist, He Jiankui, announced last fall that he had created twin girls from an embryo whose DNA he edited in his lab using the powerful gene-editing tool CRISPR.
Beijing — A Chinese court on Monday sentenced the doctor who claimed to be behind the world's first gene-edited babies to three years in prison for illegal medical practice, state media reported. Market data provided by Interactive Data. He Jiankui, who shocked the scientific community last year by announcing the birth of twin girls whose genes had allegedly been altered to confer immunity to HIV, was also fined three million yuan (US$430,000), Xinhua news agency said.
He said his goal was not to cure or prevent an inherited disease, but to try to bestow a trait that few people naturally have: an ability to resist possible future infection with HIV, the AIDS virus. Many mainstream scientists think it’s too unsafe to try, and some denounced the Chinese report as human experimentation. An embryo receives a small dose of Cas9 protein and PCSK9 sgRNA in a sperm injection microscope in a laboratory in Shenzhen in southern China's Guangdong province on Oct. 9, 2018.

The Chinese researcher who stunned and alarmed the international scientific community with the announcement that he had created the world’s … Overall, the researchers found that those who had two copies of the CCR5 variation were about 21% less likely to live until the age of 76, Nielsen and his colleagues report.

So the experiment done in China was a failure — not just ethically, but scientifically," Daley says. "This is not like other technologies.

STAT delivers fast, deep, and tough-minded journalism. This material may not be published, broadcast, rewritten, or redistributed. A third CRISPR’d baby from a second pregnancy was also born. 22 hours ago — Heidi Ledford and Nature magazine, 23 hours ago — Jennifer Hijazi and E&E News. Indeed, the DNA of Lulu and Nana showed that He’s edits were not made as intended. FORTUNE may receive compensation for some links to products and services on this website. Most scientists say that it remains too early to edit the DNA of early embryos, sperm, or eggs with the intention of creating children — so called germline edits that change the genome in ways that would be passed down to future generations — and that not all the technical and ethical issues have been addressed. What happens if the president doesn't accept the election results? "What we found is that they had significantly increased mortality," Nielsen says. He recruited couples through a Beijing-based AIDS advocacy group called Baihualin.
