Six months after a Chinese scientist was widely condemned for helping to make the world's first geneedited babies, he remains out of public view, and new information suggests that others may be interested in undertaking the same kind of work outside the United States.
A clinic in the United Arab Emirates city of Dubai emailed scientist He Jiankui to seek training in gene editing, Stanford University bioethicist Dr. William Hurlbut said ahead of a speech Tuesday at the World Science Festival in New York.
Hurlbut, whose advice He often sought, said He told him that scientists from multiple countries and families with inherited health problems had messaged support and interest in altering the genes of embryos(胚胎)to prevent or treat disease. Hurlbut gave The Associated Press the email the Dubai clinic sent to He in December but decided to hide the clinic's name.
"It reveals what eagerness there is out there to use this technology" and the need "for some sort of practical governance" of it, Hurlbut said.
Jennifer Doudna, a University of California, Berkeley, coinventor of the CRISPR geneediting tool that He used, said that she also has heard of others who want to edit embryos.
"I think they're entirely credible," she said of such reports. Doudna, who was also a speaker at the New York festival, said the field needs to focus on setting specific principles for how and when such work should proceed.
"The technology is frankly just not ready for clinical use in human embryos," although research should continue, she said. Doudna is paid by the Howard Hughes Medical Institute, which also supports AP's Health and Science Department.
Scientists and policy leaders have been debating how to set international standards or controls since He claimed in November that he had altered the genes of twin girls at conception(怀孕)to try to help them resist possible future infection with the AIDS virus.
Editing embryos is outlawed in many countries because it risks damaging other genes, and the DNA changes can be passed to future generations. Many scientists have condemned He's work, and attention has fallen on other scientists who knew or strongly suspected what He was doing.

Subject: Handheld Scanners
Ms. Hu, I received the parcel from Scan Technology 1 piece. The scanner model they sent is correct, and the quantity is right. However, I've discovered the cables and connectors are all wrong. They are not suitable for the model 8021101.
Can you do me a small favor and go through the product information website and see if the cables and connectors are still compatible (兼容的)with the 8021101 scanners? I have no wish to unpack the cables and connectors and try connecting them to the scanners. I believe we will have problem asking for an exchange if the cables and connectors are not compatible. If the website suggests an incompatibility, please contact Dan Richman and request an exchange for the collect model. (Refer to the invoice for his e-mail address.)
I will only use the scanners for our project once we have resolved the exchange issue. We should not proceed unless we get confirmation (证实)on their compatibility. I am looking to resolve this in the shortest possible time as it would be disastrous to wait for this exchange without making progress on the project.
Haojie
