A dinosaur that roamed east Asia more than 160m years ago has been named a contender for the animal with the longest neck ever known. A new analysis of bones from the beast’s neck and skull revealed that the dinosaur, known as Mamenchisaurus sinocanadorum, sported a neck 15metres long, or one-and-a-half times the length of a doubledecker bus. The fossilised remains of the creature were recovered in 1987 from 162 million-year-old rocks in the Xinjiang Uyghur Autonomous Region of north-west China, but the full length of the animal’s neck was…

How seriously should we take the US DoE’s Covid lab leak theory?
What has the US energy department said about the origin of the Covid outbreak? According to the Wall Street Journal, an updated and classified 2021 US energy department report has concluded that the coronavirus behind the recent pandemic most likely emerged from a laboratory leak but not as part of a weapons programme. Does this report mean it is more likely Covid came from a lab? Not necessarily. The report’s conclusion runs counter to that from several scientific studies as well as reports by a number of other US intelligence…
Scientist convicted of editing babies’ genes granted visa for Hong Kong
The controversial bioethicist He Jiankui has been granted a talent visa to Hong Kong, despite having a criminal record in China for illegal medical practices. At a press briefing in Beijing on Tuesday, the disgraced scientist said he was in contact with universities in Hong Kong and planned to research gene therapy for rare hereditary diseases, the Associated Press reported. He shot to fame in 2018 when he revealed that he had edited the genes of twin girls, known as Lulu and Nana, before birth, to try to make them…
Scientist who edited babies’ genes says he acted ‘too quickly’
The scientist at the heart of the scandal involving the world’s first gene-edited babies has said he moved “too quickly” by pressing ahead with the procedure. He Jiankui sent shock waves across the world of science when he announced in 2018 that he had edited the genes of twin girls, Lulu and Nana, before birth. He was subsequently sacked by his university in Shenzhen, received a three-year prison sentence, and was broadly condemned for having gone ahead with the risky, ethically contentious and medically unjustified procedure with inadequate consent from…
Fears over China’s access to genetic data of UK citizens
Rising political and security tensions between Beijing and the west have prompted calls for a review of the transfer of genetic data to China from a biomedical database containing the DNA of half a million UK citizens. The UK Biobank said it had about 300 projects under which researchers in China were accessing “detailed genetic information” or other health data on volunteers. The anonymised data is shared under an open-access policy for use in studies into diseases from cancer to depression. There is no suggestion it has been misused or…
