1. China's Mars rover completes 100 days on red planet's surface

China's Mars rover Zhurong has spent 100 days exploring the red planet's surface since it first set its wheels on Martian soil on May 22, according to the China National Space Administration (CNSA) on Aug 30.

It has traveled 1,064 meters on the surface of Mars, while the orbiter has been in orbit for 403 days.

2. Chinese researchers develop new-type fuel cell catalyst

Researchers from the University of Science and Technology of China synthesized the ultra-small platinum-based intermetallic compound electrocatalyst.

The proton exchange membrane fuel cell, which was assembled based on the catalyst, can still maintain 81.5 percent discharge power after 30,000 cycle durability tests, achieving a high power discharge and long-term cycle stability of fuel cells.

4. Chinese telescope discovers new star

Using data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), an international team of astronomers from the United States, Germany and China has discovered a rare new-type cataclysmic variable star that has never been observed before, the National Astronomical Observatories of the Chinese Academy of Sciences (CAS) announced recently.

The star was named LAMOST J0140355+392651.

5. 'Quantum drag' between water molecules observed for the first time

The "quantum drag" between adjacent water molecules has been directly observed for the first time by a team of Chinese and foreign scientists led by Professor Yang Jie from Tsinghua University.

The new discovery sheds light on the microscopic origins of water's bizarre properties, helping scientists better understand how water helps proteins function in living organisms.
