BEIJING, March 10 (Xinhua) — The following is a summary of published science and technology news of China.

MACHINE LEARNING FOR WEATHER FORECASTS

A global team of researchers has made strides in refining weather forecasting methods using machine learning.

Scientists have been looking for better ways to make weather forecasts more accurate. Despite the maturity of ensemble numerical weather prediction (NWP), the resulting forecasts are still, more often than not, under-dispersed. As such, forecast calibration tools have become popular.

This study proposes a non-crossing quantile regression neural network, for calibrating ensemble NWP forecasts into a set of reliable quantile forecasts without crossing.

CANCER-FIGHTING MECHANISM

Chinese researchers have revealed the anti-tumor characteristic of neutrophils — a type of white blood cells — and the related molecular regulation mechanism, providing new insights into cancer diagnosis and treatment.

The discovery, made by researchers at the Shanghai Institute of Immunity and Infection under the Chinese Academy of Sciences and the Fudan University, was published in the journal Cell.

NEW ENERGY PASSENGER VEHICLES

China’s exports of new energy passenger vehicles edged up 0.1 percent year on year in February, data from the China Passenger Car Association showed.

A total of 79,000 new energy passenger vehicles were exported last month, according to the association.
