Chinese researchers have determined the near-atomic structure of a protein crucial for repairing damaged DNA, an advance that may shed light on novel effective cancer therapies. Cells in our body continuously replicate to repair and replace damaged tissue, and each division requires a reprinting of the cell's DNA.
At the first hint of DNA damage, a protein known as an ATR kinase activates the cell’s built-in repair system. Scientists have now imaged this protein at unprecedented resolution, and are beginning to understand its response to DNA damage.
Dr. WANG Xiaolin, Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences, and his team reported on hundreds of three-dimensional (3D) pterosaur eggs of the species Hamipterus tianshanensis from a Lower Cretaceous site in the Turpan-Hami Basin, 16 of which contain embryonic remains, allowing for an unexpected look at the embryology and reproductive strategy of these flying reptiles. Their study was published online 30 November in Science.
The initial detection results of cosmic ray electrons and positrons based on observation by Wukong, or the Dark Matter Particle Explorer (DAMPE) launched in December 2015, were published in the latest issue of the academic journal, Nature.
China's Dark Matter Particle Explorer (DAMPE) has detected unexpected and mysterious signals in its measurement of high-energy cosmic rays. Are they from dark matter that scientists have spent decades searching for? Will the cosmic "ghost" finally show itself?
The past few days have been good for China's science and technology (S&T) community. On Monday, the Ministry of Science and Technology (MOST) announced that six new national research centers would be built in Beijing, Wuhan, Shenyang and Hefei.
