Using the Nanshan One-meter Wide-field Telescope (NOWT), astronomers from China have performed a photometric survey of the old open cluster NGC 188. In result, they identified many variable stars, one of which was detected ...
Rice, a staple crop, is widely cultivated in China. The farmers enhance the rice yield and grain quality through nitrogen (N) fertilizers. But using them in excess negatively affects crop production and harms the environment. ...
