Chinese scientists have developed a hypothesis that poisonous gas from the deep ocean may have driven one of the severest mass extinctions on the planet. Sulfureted hydrogen in the depths of the sea may have contributed to the end-Permian extinction that wiped out more than 80 percent of marine life about 250 million years ago, according to the University of Science and Technology of China.
A Chinese scientist has participated in making recommendations for human gene editing that cover basic laboratory research, and somatic and germline (heritable) genome editing, according to the Chinese Academy of Sciences (CAS). Pei Duanqing, a researcher at the Guangzhou Institutes of Biomedicine and Health, under the CAS, participated in the study and discussions leading to the recommendations, which are included in a report released in Washington D.C., according to the CAS.
The Surprisingly Early Settlement of the Tibetan Plateau[Feb 15, 2017]
As reported in a recent study in the American Journal of Human Genetics, researchers got a better grasp of the plateau's settlement history by sequencing the entire genomes of 38 ethnic Tibetans and comparing the results with the genomic sequences of other ethnic groups.
The mirror self-recognition test (MSR) is revered as a means of testing self-awareness. A scientist places a colored, odorless mark on an animal where it can’t see it, usually the head or shoulder. If the animal looks in the mirror and spontaneously rubs the mark, it passes the exam. Successful species are said to understand the concept of “self” versus “other.” But some researchers wonder whether failure is simply a sign that the exam itself is inadequate, perhaps because some animals can’t understand how mirrors work. Some animals—like rhesus monkeys, dogs, and pigs—don’t recognize themselves in mirrors, but can use them to find food. That discrepancy puzzled Mu-ming Poo, a neurobiologist at the Shanghai Institutes for Biological Sciences in China, and one of the study’s authors. “There must be some transition between that simple mirror use and recognizing yourself,” he says.
Shanghai Experts Make Firefighting much Safer[Feb 14, 2017]
SHANGHAI scientists have developed a new nanostructured material which can be used to make highly flexible and fire-resistant clothing. The nanomaterial will be safer and more eco-friendly than material previously used to make fire-resistant fabric such as asbestos.
Chinese Space Industry Pioneer Ren Xinmin Dies at 102[Feb 14, 2017]
Ren Xinmin, a renowned expert on missile and rocket technologies and chief designer of China's first satellite, has died aged 102. Ren was born in Ningguo, east China's Anhui province in 1915 and graduated from a military university in Chongqing in 1940.
