A year after scandal in China, gene-editing technology advances
At the end of 2018, Chinese researcher He Jiankui roiled the scientific world by announcing he had helped make the world’s first gene-edited babies, altering the DNA of Chinese twin girls to try to make them resistant to HIV, the virus that causes Aids. The scandal brought attention to the scientific, ethical, social and legal challenges of research into gene editing, with a panel convened by the World Health Organization (WHO) director-general saying in March that it would be “irresponsible” for scientists to use gene editing for reproductive purposes. Beijing has since tightened its laws on genetic engineering, drafting new rules in the past year to tackle the previously loosely regulated

China is planning to build a ‘paradise for physicists’
Scientists in southern China are planning to create machines that will be used to unravel the mysteries of the building blocks of the universe. They said two ring-shaped electron-ion colliders – one 1.2 miles long – will be built in Huizhou, a city in Guangdong province, beginning in 2025 and they will be designed to accelerate electrons to close to the speed of light. The project – known as the Electron-Ion Collider of China, or EICC – will see electrons being fired at the nuclei of heavy elements such as iron or uranium at high speeds. The scientists said the machines – among the biggest of their kind – would act as “cameras” when these collisions took place. This will allow them to study

Why Chinese mothers go abroad for sperm donors
In China, the marriage rate is falling and more affluent single women are seeking to become mothers without husbands. They are turning to overseas options. Unmarried women in China are largely barred from accessing sperm banks and in-vitro fertilization (IVF) treatment, where an egg is fertilized by sperm outside the body. One single mother by choice tells her story.

Where is the rogue Chinese scientist who gene-edited babies?
The whereabouts of a rogue Chinese scientist and his “gene-edited babies” remain a mystery, as the release of more of his research data triggers renewed discussions of his attempt to create the first gene-edited babies.  He Jiankui, former associate professor of life science at Southern University of Science and Technology of China in Shenzhen, shocked the world last year when he announced that he had edited the genes of the twin girls to prevent them from inheriting HIV from their father. The claim unleashed a storm of criticism from the international scientific community for the unsafe and unethical use of the technology. Soon after He announced his “success” in creating the world’s first

Chinese astronomers discover black hole so big that it shouldn’t exist
Chinese astronomers have discovered a black hole in the Milky Way that current scientific theory says is too big to exist. Scientists from the National Astronomical Observatory of China say the find, dubbed LB-1, has 70 times the mass of the sun, even though physics says that is impossible. “We were so shocked we could not believe what we saw,” researcher Liu Jifeng said in Beijing on Thursday. He said he and his colleagues consulted astronomers from around the world and after three years of fact-checking announced their find in an article published by the scientific journal Nature. Present theory says that stars are made up of various elements, ranging from light gas to heavy metals. Lighte

Chinese pet detective reunites lost furry friends with owners
If your beloved furry friend goes missing in China, hiring a pet detective is now a way to increase your chances of a happy reunion. Equipped with hi-tech investigative tools, Shanghai-based private sleuth Sun Jinrong is handling cases across the country.  In about seven years of pet detecting, he has found about 1,000 wayward animals and claims a success rate of 60-70%.

Meet the man who put feathers on dinosaurs
One of the most delightful modern discoveries is the realization that dinosaurs still roam our planet. We just call them birds.  For every adult who was once a dinosaur-obsessed 8-year-old kid, we can thank Professor Xu Xing, a Chinese paleontologist and one of the world’s most prolific dinosaur hunters.  He is on a mission to broaden our mental images of dinosaurs and improve the popularity of all dinosaurs -- not just the famous species.  “If you ask kids about their favorite dinosaurs, they usually say Stegosaurus or Tyrannosaurus Rex, right? Because it’s all deeply embedded in textbooks and popular science. Even now there’s a lot of new fossils being discovered in China and not many peop

China’s Mars mission passes landing test for 2020 launch
China has completed a test of its Mars lander, placing the country on track for its first mission to the red planet next year. In the span of several decades, China has emerged from an economic backwater to a rising space power, with recent breakthroughs including the landing of a rover on the far side of the moon. In developing its Mars mission, China is following in the footsteps of the US, which in the 1970s successfully put the Viking landers on Mars and last landed a rover there in November 2018 in its InSight mission.  China’s space program could contribute to international efforts to understand the climate and natural resources on Mars. While it is cold (the average temperature is ab

China wants its own Yellowstone National Park
China plans to develop a unified national park system by 2020, after gathering inspiration from wilderness recreation areas in the United States.  Chinese officials in charge of the project have visited Yellowstone National Park and other protected areas and met with conservation experts to prepare for the task.  Chinese state media reports said 10 national parks have started operating on a trial basis to protect ecological systems. The conservation efforts are said to protect threatened plant species and animals such as the giant panda, Siberian tiger and Amur leopard.

Chinese scientists use AI to diagnose genetic disorders in babies
Chinese scientists say they've developed an AI-powered software to help screen newborns for genetic disorders through facial scans. Researchers from the Shanghai Children’s Medical Center and the Shanghai Pediatric Center said their new assistive diagnosis tool, which they described as the first of its kind, was designed to detect more than 100 disorders with distinctive facial features, according to a report by state-owned China News Service. They said their AI-enabled tool would be used for initial screening, helping to avoid missed or wrong diagnosis of newborns. Prominent facial features of children with Cornelia de Lange syndrome (CdLS), for example, include thin eyebrows that often me
