Ultracold atoms can unlock new understanding of how cosmic rays behave.
How molten carbon crystallizes into either graphite or diamond is relevant to planetary science, materials manufacturing and nuclear fusion research. A new study uses computer simulations to study how molten carbon crystallizes into either graphite or diamond at temperatures and pressures similar to Earth’s interior, challenging the conventional understanding of diamond formation.
Research teams led by CAS institutions including the Institute of Geology and Geophysics (IGG) and the National Astronomical Observatories (NAOC), along with Nanjing University and others, have made four landmark discoveries based on the South Pole–Aitken Basin samples. Their findings were published in four cover articles in the journal Nature.
In a paper published in National Science Review, a team of researchers utilized an astronomical telescope equipped with a quantum-limited superconducting mixer as the receiver. The experiment successfully demonstrated real-time high-definition video wireless transmission at 500 GHz over a record distance of 1.2 km at a dry site situated 4445 meters above sea level. This experiment offers valuable insights for the future development of satellite and airborne-to-ground communication technologies and their applications.
A 2.35-billion-year-old meteorite with a unique chemical signature, found in Africa in 2023, plugs a major gap in our understanding of the Moon’s volcanic history.
