A team of scientists from the Chinese Academy of Sciences has developed an ultra-black coating that can absorb 99.3% of light across a wide range of wavelengths, potentially improving image quality for cameras and space telescopes. The thin film, made of titanium-aluminium-carbon composite and silicon dioxide, can prevent unwanted scattered light from entering camera lenses and creating glare or bright spots in photos. The material is highly durable and can withstand extreme temperature changes and friction, making it suitable for various applications in precision optics.

Chemists from the University of Western Ontario and the Chinese Academy of Sciences have accidentally created the smallest and tightest molecular knot ever, consisting of just 54 atoms forming a 'trefoil' knot with no loose ends, surpassing the previous record of 69 atoms. This breakthrough in molecular knot synthesis could have implications for understanding natural knots in DNA, RNA, and proteins, as well as for developing improved plastics and polymers. The knot, made of gold atoms, assembles itself and has a backbone crossing ratio (BCR) of 18, indicating its strength. This achievement could motivate further research into self-assembling molecular structures.

The Chinese Academy of Sciences (CAS) spacecraft Einstein Probe, in collaboration with the European Space Agency (ESA) and the Max Planck Institute for Extraterrestrial Physics (MPE), is set to launch in January 2024. Equipped with innovative X-ray instruments, the mission aims to survey the sky and detect powerful X-ray emissions from celestial objects such as neutron stars and black holes. The mission will contribute to advancing our understanding of high-energy physics and the origin of gravitational waves. The spacecraft's Wide-field X-ray Telescope (WXT) will observe large areas of the sky, while the Follow-up X-ray Telescope (FXT) will study interesting events in more detail. ESA's contribution includes developing the scientific instrumentation and providing ground stations for data download.

China's Zhurong rover, part of the Tianwen-1 mission, has discovered evidence of possible liquid water on Mars' surface as recently as a few hundred thousand years ago. The rover observed salt-rich dunes in the Utopia Planitia region that showed cracks and crusts, indicating the possible presence of water. The team estimates that these features formed between 1.4 million and 400,000 years ago, far more recent than previously thought. This discovery could provide critical clues to future exploration missions searching for signs of extant life, particularly at low latitudes with comparatively warmer, more amenable surface temperatures.
