Tianwen-1: Zhurong rover finds evidence of water at low latitudes on modern Mars

The Zhurong rover has found evidence of water on dune surfaces on modern Mars by providing key observational proof of liquid water at low Martian latitudes, according to a study led by Professor Qin Xiaoguang from CAS’s Institute of Geology and Geophysics.

Astronomers image for the first time a black hole expelling a powerful jet

An international team of scientists led by Dr. Lu Rusen from CAS’s Shanghai Astronomical Observatory has used new millimetre-wavelength observations to produce an image that shows, for the first time, both the ring-like structure that reveals the matter falling into the central black hole and the powerful relativistic jet in the prominent radio galaxy Messier 87.

Middle Ordovician “Marine Dwarf World” found from Castle Bank, Wales

An unusually well-preserved “Marine Dwarf World” from 462 million years ago was found at Castle Bank, Wales by a team led by CAS’s Nanjing Institute of Geology and Palaeontology. The site comprises over 150 species, with many of miniaturized body size. It is one of the world’s most unexpected fossil sites.

19-hour days for a billion years of Earth’s history: study

Day length was shorter because the Moon was closer. “Over time, the Moon has stolen Earth’s rotational energy to boost it into a higher orbit farther from Earth,” said Ross Mitchell, geophysicist at CAS’s Institute of Geology and Geophysics.

Researchers discover chemical evidence for pair-instability supernova from a very massive first star

A new study led by Professor Zhao Gang of CAS’s National Astronomical Observatories has identified a chemically peculiar star (LAMOST J1010+2358) in the Galactic halo as clear evidence of the existence of PISNe from very massive first stars in the early Universe. The study was based on a LAMOST survey and the Subaru telescope.

Hidden ice melt in Himalaya: study

The mass loss of lake-terminating glaciers in the greater Himalaya has been significantly underestimated, due to the inability of satellites to see glacier changes occurring underwater. The finding has critical implications for the region’s future projections of glacier disappearance and water resources.

Scientists find key evidence for existence of nanohertz gravitational waves

Chinese scientists have recently found key evidence for the existence of nanohertz gravitational waves, marking a new era in nanohertz gravitational research. The research was based on pulsar timing observations carried out with the FAST.

Chinese researchers achieve superionic hydride ion conduction at ambient temperatures

A research team from CAS’s Dalian Institute of Chemical Physics demonstrated a technique that enables a room-temperature all-solid-state hydride cell by introducing and exploiting defects in the lattice structure of rare earth hydrides.

Chinese paleogeneticist Fu Qiaomei awarded UNESCO-Al Fozan International Prize for the Promotion of Young Scientists

Fu Qiaomei, a paleogeneticist at the Chinese Academy of Sciences, received the UNESCO-Al Fozan International Prize for the Promotion of Young Scientists in Science, Technology, Engineering and Mathematics (STEM) on June 19 in Paris, France.

Arthropods in high-diversity forests contribute to improved productivity

An international team of researchers led by Professor Ma Keping from CAS’s Institute of Botany has shown that forests with higher tree species richness tend to have greater arthropod diversity.
