BEIJING, May 24 (Xinhua) -- The following is a summary of published science and technology news of China.

IMAGE CAPTURED BY BEIJING-3C SATELLITE CONSTELLATION

The Beijing-3C satellite constellation captured its first image on Tuesday, according to a report from industry newspaper China Space News.

The image was received by a satellite ground station in Beijing. It shows a collection of buildings located next to a river and has clear textures, distinct layers, rich detail, vibrant colors, and an overall smooth image quality.

NATIONAL SPECIES DATABASE

China has recently released an updated version of the national species database, known as the Catalogue of Life China 2024 Annual Checklist, the Chinese Academy of Sciences (CAS) said Thursday.

The list recorded a total of 155,364 species and subspecies, up 6,690 from the 2023 figure.

The list was jointly compiled by researchers from the Institute of Zoology, the Institute of Botany, the Institute of Microbiology, the Institute of Oceanology and the Chengdu Institute of Biology under the CAS as well as other institutions.

ICE SURFACE PREMELTING

A group of Chinese researchers has observed the atomic resolution image of an ice surface and discovered that the ice surface begins to melt at minus 153 degrees Celsius, according to a research article published in journal Nature on Wednesday.

The researchers from the School of Physics of Peking University and Interdisciplinary Institute of Light-Element Quantum Materials used the domestic qPlus scanning probe microscope to develop an imaging technique that can distinguish hydrogen atoms and chemical bonds, accurately recognize the orientation of water molecules and precisely locate the distribution of dangling hydrogen atoms.
