​China's large scientific infrastructure: the Shanghai Synchrotron Radiation Facility, or SSRF, is what's known as the country's first third-generation synchrotron radiation light source. The Nautilus-like building produces light that is hundreds of millions of times more powerful than an ordinary X-ray. It's known as synchrotron radiation and is created when charged electrons move close to the speed of light in a vacuum and change their direction.

The upgraded Shanghai Synchrotron Radiation Facility (SSRF), a key sci-tech infrastructure in east China that aims to reveal the mysteries of the microscopic world, passed national inspection and acceptance on Wednesday. Started in November 2016, the SSRF upgrades were completed in July 2023. They include the construction of 16 state-of-the-art beamlines and experimental stations, auxiliary laboratories, user data centers, support systems and associated facilities, as well as an accelerator performance upgrade, said Tai Renzhong, vice president of the Shanghai Advanced Research Institute of the Chinese Academy of Sciences.

Dr. ZHOU Zheng's group from the Institute of Biophysics and Dr. Ed Luk's group from Stony Brook University revealed the molecular mechanism of Swc5 in regulating SWR-catalyzed histone exchange. The study lays the molecular basis of Swc5 in recognition of H2A-H2B and provide critical insight into how Swc5 facilitates SWR-catalyzed nucleosome editing.
