BEIJING, May 14 (Xinhua) -- The following is a summary of published science and technology news of China.

ICE AGE HUMAN MIGRATIONS

Chinese scientists and their international counterparts have recently discovered evidence of Ice Age human migrations from northern coastal China to the Americas and Japan by tracing contemporary and ancient human DNA.

Researchers from the Kunming Institute of Zoology under the Chinese Academy of Sciences and other institutions in China, as well as from Italy, collected more than 100,000 contemporary and 15,000 ancient DNA samples from Eurasia, and identified 216 contemporary and 39 ancient samples which belong to an ancestral lineage that exists in mitochondrial DNA and can be used to track kinship through female lineage.

The researchers discovered two migration waves from northern coastal China to the Americas. The first was during the Ice Age between 26,000 years ago and 19,500 years ago, and the second during the subsequent melting period between 19,000 years ago and 11,500 years ago.

POWER BATTERY OUTPUT

China's power battery output and installed capacity saw rapid expansion in April, industry data shows.

The power battery output stood at 47 gigawatt hours last month, up 38.7 percent year on year, according to the China Automotive Battery Innovation Alliance.

MOUNTAIN GLACIER DETECTION

A Chinese aerial remote sensing system has obtained effective mountain glacier detection data through an ongoing combined detection experiment.

The Chinese Academy of Sciences (CAS) and Wuhan University are conducting a sky-ground scientific experiment to test the condition of glaciers in the Haibei Tibetan Autonomous Prefecture in northwest China's Qinghai Province.

The experiment has applied radars in three bands -- P-band, L-band and Very High Frequency (VHF) -- and undertaken 11 flights, among which seven carried out tomography and interferometric imaging and four conducted perspective imaging. Enditem
