Planting for the future

 

The Germplasm Bank of Wild Species in Kunming, Yunnan province, is a trove of hundreds of thousands of invaluable plant seeds. 

For some, life is put on pause at the very beginning. In the basement of a four-story building in Kunming's northern suburbs, hundreds of thousands of precious plant seeds are carefully stored at — 20 C. This Germplasm Bank of Wild Species, located in Yunnan's provincial capital in Southwest China, is the largest facility of its kind in Asia.

It houses more than 94,000 plant seed accessions from around 11,000 wild species, representing over one-third of China's wild seed plants.

The seeds are carefully stored in specially designed glass bottles, which are lined up on rows of shelves in a concrete warehouse 30 meters underground.

According to Cai Jie, head of the seed bank's germplasm collection center, Chinese researchers discovered ancient lotus fruit in the peat layer of a dried-up pond in Pulandian, Northeast China's Liaoning province, in 1952.

Lab tests determined that the fruit had been buried for 1,288 years. Surprisingly, the seeds inside the fruit successfully germinated and grew into beautiful flowers after their tough outer shells were ground away.

"This magical discovery had a profound impact on my career," Cai says.

"Seeds are natural time capsules, carrying the genetic code of plants. They can revive at the right moment. We preserve seeds with great care because we need to have reverence for nature and believe in the power of life."

New Frost-Resistant Sand-Control Agent

  Across China: Chinese researchers develop new frost-resistant sand-control agent LANZHOU -- A Chinese research team has developed a chemical sand-fixation material suitable for use in cold desert regions, which is expected to serve as a new tool for sand control and desertification prevention in such areas. The application of chemical materials to stabilize shifting sands is one of the primary methods of desertification control. This approach involves the use of adhesive chemical substances to bind loose sand particles together, thereby mitigating encroachment by wind-blown sand. However, conventional chemical sand-fixation materials have been mainly designed for hot and arid regions. In colder, high-altitude or high-latitude desert regions, such as the Qinghai-Xizang Plateau and the Mongolian Plateau, which are located in Northwest, Southwest and North China, cooler temperatures often render traditional methods of sand control ineffective. Researchers from the Northwest Institut...

Bamboo In The World’s Longest Sea Bridge

Image
  How Chinese engineers used bamboo in the world’s longest sea bridge, and more Chinese scientists have been working on new technologies to make stronger and more durable bamboo-based materials for large-scale infrastructure, reinforcing the country’s position as a leader in the emerging eco-friendly industry. Bamboo, which is known for its rapid growth and high strength, was engineered into composite panels used on the scenic platforms that stretch for kilometres along the  Hong Kong-Zhuhai-Macau Bridge , the official Science and Technology Daily reported on Wednesday. Six years after they were installed on the bridge – the world’s largest sea crossing – the bamboo-based panels have withstood sunlight, typhoons and seawater corrosion, remaining “as solid as ever”, according to the report. Lou Zhichao, from Nanjing Forestry University’s Bamboo Research Institute, said most of the world’s bamboo was grown in developing countries. “China is not only the world’s largest bamboo pr...

Blueprint Of Human Brain Cortex

  Chinese scientists uncover complex blueprint of human brain cortex BEIJING -- Researchers from the Institute of Automation at the Chinese Academy of Sciences have revealed the intrinsic relationship between the topological structure of human brain cortex connections and genetic characteristics, according to a study published in the Journal of Neuroscience. Fan Lingzhong, a researcher at the institute, explained that neural networks operate as human think, learn, or perceive the world, with trillions of connections enabling rapid information transfer. The study addresses a fundamental question: How do these intricate connections form, and why do distinct brain regions exhibit such orderly distribution across the cortex? "The brain begins following a genetic 'blueprint' during embryonic development," Fan noted. Researchers proposed a hypothesis: genetic encoding and cortical connectivity are not directly correlated due to the vast numerical disparity between genes and...
