A recent study led by the Institute of Atmospheric Physics at the Chinese Academy of Sciences sheds new light on how human activities have altered the composition of the atmosphere over time, particularly focusing on secondary organic aerosols (SOA). These aerosols play a significant role in air quality and climate change, making it crucial to understand their evolution from the preindustrial era to the present day.

The first electron beam of the High Energy Photon source (HEPS) was accelerated to 500 MeV with better than 2.5 nC of bunch charge by the Linac on March 14, which was a key milestone of the HEPS project—HEPS beam commissioning had begun.

With support from the Major Achievements Cultivation Program of the Chinese Academy of Sciences, the Beam Instrumentation (BI) Group of the Accelerator Division of the Institute of High Energy Physics has completed a new upgrade of beam position measurement (BPM) electronics in the BEPCII storage ring, and all 98 sets of imported analog electronics have been replaced by self-developed electronics with independent intellectual property rights. After nearly a year of online operation at the BEPCII storage ring (Sept. 2021–Jul. 2022),the resolution of the self-developed electronics is better than 0.1 μm and the beam orbit stability is better than 10 μm @ 72 hours,fully satisfying or even exceeding the experimental requirements of the BEPCII collision mode and synchrotron radiation mode.

Large scale neutral hydrogen (HI) survey of the local universe is one of the major science drive for the Five-hundred Meter Aperture Spherical radio Telescope (FAST) project. As pointed out by Prof. Rendong Nan, the founder and the late Chief Scientist & Chief Engineer of the FAST project, the FAST HI survey can address many important astrophysical questions, such as investigating the extent of HI disks; studying the extended rotation curve to unprecedented distance; mapping out the distribution of dark matter in the local group; searching for low mass galaxies in void regions; and detecting Cold Dark Matter Satellites and possible HI companions.

Fragaria, commonly known as strawberry, is one of the most popular berry fruits and also one of the youngest domesticated plants.
