China will select its third group of astronauts this year, Yang Liwei, deputy director of China Manned Space Engineering Office said Wednesday.

The first and second astronaut groups were all previously airforce pilots. However, the selection of the third group will also include engineers who will be responsible for maintenance, assembly and other tasks, Yang, China’s first astronaut, said at the opening ceremony of the country’s inaugural astronaut photography exhibition.

Photos taken by astronauts from different periods reflect the development of China’s space exploration, he said.

“When I was on the spacecraft, I took photos through two windows. Astronauts on the Tiangong space lab had more perspectives for photography. They had a better working environment and living space than before,” he said.

Looking at the Earth from space is different with looking out from an airplane, Yang said. “The higher you are, the larger your angle of view is. The Earth seen from space is sphere-shaped, and mountains and rivers also look different.”

“As Chinese, we are so proud when we look at the Earth,” he said, reminiscing about viewing the motherland from space.

Yang hopes the exhibition will cultivate an increased interest in space among the general public. “Space exploration is a massive project which needs the support of more people, especially youth,” said Yang.

Chinese medical experts have developed Z2, an antiviral peptide that can kill the Zika virus.

The achievement was published in the international journal Nature Communications on July 26 and has aroused wide attention in the global medical field, China News reported.

The World Health Organization warned about the Zika virus after 2007 outbreak, calling it a public health emergency of international concern. More than 80 countries have reported infection cases by March 2017.

The new drug has been show to kill the Zika virus in rats and can prevent pregnant rats from passing on the virus. It was developed by Lu Lu and Jiang Shibo’s research team at the School of Basic Medical Sciences at Fudan University and by research teams at the Shanghai Public Health Clinical Center as well as the Institute of Microbiology and Epidemiology under the Academy of Military Medical Sciences.

Jiang said there is currently no vaccine or drug that can effectively prevent infection. But the Z2 peptide can combine with surface proteins of the virus to make it inactive.

Jiang added that the peptide is able to penetrate the placental barrier. This not only lowered the infection rate of the pregnant rat but also that of the fetus, stopping vertical transmission.

Experts said that the polypeptide inactivating agent could become a new drug for preventing the virus, as it is also safe for high risk groups, including the pregnant.
