BEIJING, April 22 (Xinhua) -- The following is a summary of published science and technology news of China.

BRAIN-COMPUTER INTERFACE TOOL

A team of Chinese scientists have found during a clinical trial that brain-computer interface (BCI) rehabilitation can improve upper limb motor function in patients with stroke.

The researchers from the Beijing Tiantan Hospital under Capital Medical University led an investigator-initiated, 17-center clinical trial in China, in which 296 patients with ischemic stroke were randomized to receive BCI or traditional rehabilitation training for one month.

The primary efficacy outcomes showed that the score change from baseline of BCI group was noticeably higher than that of control group, according to a study recently published in the journal Cell Med.

NEW ALGORITHM TO RECOGNIZE CMES

Chinese researchers have developed a new algorithm to automatically derive kinematic parameters of coronal mass ejections (CMEs) based on machine learning, according to a recent research article published in the Astrophysical Journal Supplement Series, highlighting the great significance of this algorithm in predicting catastrophic space weather.

CMEs are large scale masses of plasma thrown from the sun into interplanetary space and are considered the largest form of energy release in the solar system.

The algorithm can identify relatively weak CME signals and generate accurate morphology information concerning CMEs. It is expected to assist with real-time CME warnings and predictions.

SUBGLACIAL LAKES IN ANTARCTICA

Chinese scientists have newly discovered 46 subglacial lakes beneath the ice sheet in East Antarctica, using an innovative analysis method.

Scientists believe this new method significantly improves the efficiency and accuracy of subglacial lake discovery and also holds promise for extending to the detection and labeling of more types of subglacial environments in Antarctica. Enditem
