RESEARCH AND DEVELOPMENT

 

First Inbred Line Pig Cloned

 

Researchers at Yunnan Agriculture University cut off a tiny piece of skin (0.5 cm2) from a newly born boar’s ear for further cell culture and division. They injected the 3rd generation of the cells into the denucleated egg cells collected from sows, and transplanted the divided cells (2nd-8th) into the sows’ Fallopian tubes for further development. The cloned piglet was born 116 days later.

 

The donor is a pure breed black boar derived from a Banna inbred line which has passed for 20 generations, enjoying a DNA similarity as high as 99%. The cloned piglet, the first of its kind in the world, is healthy for all indicators, suggesting the success of the cloning. The development will eventually result in more animal models and xenotransplantation.

 

Superconductivity Found in One-Atomic-Layer

 

Not long ago, a study, led by XUE Qikun, CHEN Xi, and JIA Jinfeng at Tsinghua University Dept. of Physics, in collaboration with a team headed by MA Xucun with the Chinese Academy of Sciences Institute of Physics, Prof. WANG Yayu, Tsinghua University Dept. of Physics, Prof. LIN Haiqing at the Chinese University of Hong Kong, and Prof. LIU Ying of the Pennsylvania State University Department of Physics and Material Research Institute, has found superconductivity in one-atomic-layer metal films grown on Si substrates. One-atomic-layer is the ultimate thickness a practical material can reach. The finding, published in the recent online issue of Nature Physics, renders a solution to the question concerning how thin a superconductor can be.

 

Strong Crystal Size Effects on Deformation Twinning

 

Under the guidance of her tutor, YU Qian, a post-graduate at Xi’an Jiaotong University State Key Laboratory for Mechanical Behavior of Materials, in collaboration with Prof. LI JU with University of Pennsylvania Department of Materials Science and Engineering, and Dr. HUANG Xiaoxu of Technical University of Denmark Laboratory for Sustainable Energy, made an in-depth study of the deformation twinning behavior of nano-sized metal crystals and its impact on the dynamic performance of the materials. YU and coworkers found that the size of monocrystals is of a strong effect on the dynamic performance. The finding, published in the recent issue of journal Nature, provides a meaningful insight of materials performance evaluation and design, especially on material processing at the nano-scale utilizing the strong crystal size effect.
