A Chinese scientist who was imprisoned for his role in creating the world’s first genetically edited babies says he has returned to his laboratory to work on the treatment of Alzheimer’s and other genetic diseases. In an interview with a Japanese newspaper, He Jiankui said he had resumed research on human embryo genome editing, despite the controversy over the ethics of artificially rewriting genes, which some critics predicted would lead to demand for “designer babies”. “We will use discarded human embryos and comply with both domestic and international rules,” He…

Forensic spray using jellyfish protein could speed up fingerprint detection
Scientists have developed a forensic spray using a protein found in jellyfish that shows up fingerprints in just 10 seconds. They say that the dye spray could make forensic investigations quicker and more effective. It is also water-soluble and has low toxicity. Traditional forensic methods either use toxic powders that can harm DNA evidence or petrochemical solvents that are bad for the environment, the sale of which is increasingly restricted. The dyes in the spray are based on a fluorescent compound called green fluorescent protein (GFP), which has previously revolutionised…
Scientist fed classified information to China, says Canada intelligence report
A leading research scientist at Canada’s highest-security laboratory provided confidential scientific information to Chinese institutions, met secretly with officials and posed “a realistic and credible threat to Canada’s economic security” according to newly released intelligence reports. The dismissal of Xiangguo Qiu and her husband, Keding Cheng has been shrouded in mystery ever since the couple were escorted from Winnipeg’s National Microbiology Laboratory in 2019 and formally fired two years later. Intelligence assessments released late on Wednesday afternoon alleged that Qiu’s “close and clandestine relationships” with Chinese institutions which showed a…
Genetics journal retracts 17 papers from China due to human rights concerns
A genetics journal from a leading scientific publisher has retracted 17 papers from China, in what is thought to be the biggest mass retraction of academic research due to concerns about human rights. The articles were published in Molecular Genetics & Genomic Medicine (MGGM), a genetics journal published by the US academic publishing company Wiley. The papers were retracted on 12 February after an agreement between the journal’s editor in chief, Suzanne Hart, and the publishing company. In a review process that took over two years, investigators found “inconsistencies” between…
My path to inner peace, via ‘Dalifornia’ in southwest China
Nine months after I moved to Dali, in the autumn of 2020, I finally set off to climb Cangshan, the high mountain which towers over this valley in southwest China. Each morning, I had looked up at the top of its imposing ridge line, 2,000m above the village of Silver Bridge, north of Dali’s historic old town, that for a while I called home. Eighteen glacial gorges separated the 19 peaks, each carved by a running stream. Ever since moving there, I had fantasised about standing on top of that…
Teenagers with more siblings have worse mental health, study suggests
From Cain and Abel and the Brothers Karamazov to Cinderella, the warmth and support provided by siblings has hardly been taken for granted. Now, researchers have found that children who moan about their brothers and sisters may have good reason to complain: the more siblings teenagers have, the more it hits their happiness, they claim. A study of secondary schoolchildren in the US and China found that those from larger families had slightly poorer mental health than those from smaller families. The greatest impact was seen in families with multiple…
Giganto, largest ever primate, died out due to diet change, say scientists
It was the largest primate ever to have roamed the Earth, but just why – and when – our distant cousin “giganto” ended up extinct has been something of a mystery. Now researchers say the enormous ape was victim of an unfortunate choice of food when its preferred snacks became scarce. Gigantopithecus blacki roamed mainland south-east Asia 2 million years ago, with estimates suggesting it was three metres tall and weighed 200-300kg – roughly three to four times a human’s weight. Previous studies have shown giganto’s range decreased considerably by…
Moon’s resources could be ‘destroyed by thoughtless exploitation’, Nasa warned
Science and business are heading for an astronomical clash – over the future exploration of the moon and the exploitation of its resources. The celestial skirmish threatens to break out over companies’ plans to launch dozens of probes to survey the lunar landscape over the next few years. An early pioneer – Peregrine mission one – is set for launch this week. The aim of this extraterrestrial armada – largely funded through Nasa’s $2.6bn Commercial Lunar Payload Services (CLPS) initiative – is to survey the moon so that minerals, water…
Academic paper based on Uyghur genetic data retracted over ethical concerns
Concerns have been raised that academic publishers may not be doing enough to vet the ethical standards of research they publish, after a paper based on genetic data from China’s Uyghur population was retracted and questions were raised about several others including one that is currently published by Oxford University Press. In June, Elsevier, a Dutch academic publisher, retracted an article entitled “Analysis of Uyghur and Kazakh populations using the Precision ID Ancestry Panel” that had been published in 2019. The study by Chinese and Danish researchers used blood and…
WHO requests details about respiratory illness clusters in parts of China
The World Health Organization has asked China for details about a rise in respiratory illnesses that has been reported in northern parts of the country, particularly among children. Epidemiologists have warned that as China heads into its first winter since the lifting of zero-Covid restrictions, natural levels of immunity to respiratory viruses may be lower than normal, leading to an increase in infections. Several countries, including the US and the UK, experienced large waves of respiratory viral infections in the first winter after Covid restrictions were lifted as people had…
