BEIJING, Oct. 10 (Xinhua) -- The following are the highlights of China's science news from the past week:

MARS PROBE

China's Mars probe Tianwen-1 successfully conducted a deep-space maneuver on Friday night (Beijing time), according to the China National Space Administration.

The probe completed the maneuver at 11 p.m. after its main engine worked for over 480 seconds.

The maneuver took place 29.4 million km from Earth, aiming to help the probe achieve a sound rendezvous with Mars.

SCREENING HAZARDOUS COMPOUNDS

Chinese researchers have developed a new method to improve the screening of hazardous compounds in agricultural products, providing a new strategy for ensuring food safety.

This method was successfully applied to analyze 180 veterinary drugs in milk, 220 pesticides in tomatoes, and 50 mycotoxins in maize, respectively. Results showed that it achieves a higher rate of identification and lower false results for targeted compounds compared with previous methods.

AIRBORNE BACTERIA

Researchers have found that weather and movement over long distances affect airborne bacterial diversity.

The differences in community structures among the airborne bacteria mainly depended on meteorological parameters, said their research article. Due to frequent rainfall, aerosol samples over the Qinghai-Tibet Plateau were washed down and showed the lowest diversity among the regions under examination.

5G SURGICAL ROBOT

A Chinese medical team has performed a remote radical cystectomy on a patient 3,000 kilometers away with the help of a domestically-developed surgical robot using 5G.

The robot accurately repeated the doctor's movements, removing the lesions in the targeted area. Enditem
