BEIJING, July 15 (Xinhua) -- The following is a summary of published science and technology news of China:

SMALL NUCLEAR REACTOR

The core module of the world's first commercial small modular reactor (SMR) completes its factory acceptance test on Thursday, marking a breakthrough in the technological innovation of SMR in China.

The reactor, also known as the Linglong One, is a multi-purpose small modular pressurized water reactor self-developed by the China National Nuclear Corporation.

AI-BASED METEOROLOGICAL MODEL

Chinese researchers have developed an artificial intelligence (AI)-based model with three-dimensional neural networks for accurate and medium-range global weather forecasts, according to a recent research article in the journal Nature.

The most accurate current forecast system is the numerical weather prediction (NWP) method, although it is computationally expensive. Daily weather forecasts, extreme disaster warnings, and climate change predictions are all realized by the NWP method that relies on high-performance computing and complex physical models.

NEW FOSSILIZED GALEASPID FISH

Researchers have discovered a new fossilized galeaspid fish, dating back some 438 million years, in the Xiushan Formation in central China's Hunan Province.

The creature lived during the Silurian era, which was about 410 to 440 million years ago. Enditem
