BEIJING, Sept. 7 (Xinhua) -- The following are the highlights of China's science news from the past week:


China's first domestically built polar icebreaker will begin its maiden voyage in October from the southern Chinese city of Shenzhen. The voyage for "Xuelong 2," or "Snow Dragon 2," will start during the seventh China Marine Economy Expo, which will run from Oct.14 to 17.

On its maiden voyage, Xuelong 2 will sail for Antarctica together with "Xuelong," the only Chinese icebreaker in service, in the country's 36th research mission to the region.


An international research team recently discovered a segmented bilaterian fossil about 550 million years old in China, which represents one of the oldest mobile and segmented animals.

The new fossil species, found in the Yangtze Gorges area, is named Yilingia spiciformis. It is directly connected with its trace produced immediately before its death, allowing the researchers to unravel critical evolutionary puzzles of the bilaterally symmetric animals, also known as bilaterians.


A team of Chinese researchers at Nanjing University have created a controllable quantum superposition of the two complementary states of light both as a particle and a wave.

The research, conducted by a team led by Professor Ma Xiaosong, demonstrated conclusively that light can not only be in wave or particle states but also in a quantum superposition of the two. The finding was published in the latest issue of the journal Nature Photonics.


An international team of researchers have identified a cold-sensing receptor protein that helps organisms to respond to extreme cold.

In the study, researchers from the University of Michigan in the United States, Huazhong University of Science and Technology in China and Ulsan National Institute of Science and Technology in the Republic of Korea used C. elegans, a type of worm with a simple and mapped genome, as the model to study the cold-sensing mechanism.
