BEIJING, Dec. 8 (Xinhua) -- The following is a summary of published science and technology news of China:

AMMONIA-FUELLED ENGINE

China's first medium-speed high-power ammonia-fuelled engine ignited successfully in Dalian, northeast China's Liaoning Province, marking China's breakthrough in the related key technologies.

The ammonia-fuelled engine, featuring low carbon, high safety, and good interchangeability, was independently developed and innovated by China's CRRC Dalian Co., Ltd. (CRRC Dalian) based on its self-developed diesel engine technology.

This environmentally friendly engine can reduce carbon emissions by 80 percent and produce up to 208 kilowatts of power from a single cylinder, with ammonia energy accounting for 85 percent.

FOREST FIRE CARBON EMISSIONS

The Chinese Academy of Sciences (CAS) on Thursday published the research on carbon emissions from global forest fires, urging effective control of extreme forest fires and the inclusion of resultant emissions into the global carbon accounting system.

In the Blue Book on Forest Fire Carbon Emissions Research (2023), the CAS also called for building a comprehensive and scientific carbon emission monitoring and measurement system.

The blue book included the latest research achievements on global carbon emissions by experts from the Institute of Applied Ecology, the Institute of Earth Environment and the Institute of Atmospheric Physics, all under the CAS.

ROBOTIC ROBOT

An international team of researchers from Germany and China has developed a robotic robot with a flexible spine capable of performing lateral flexion, which displayed heightened agility compared to other existing four-legged robots.

The study about this 40-centimeter-long robot nicknamed NeRmo, which emulates the morphology and tendon system of a real mouse, was published on Thursday in the journal Science Robotics.

The researchers from the Technical University of Munich and Sun Yat-sen University designed this neurorobotic, mouse-inspired robot with artificial nylon tendons, which support compliant and smooth spine-like movement. Enditem
