Chinese Researchers Discover How Bird Feathers Resist Tearing[Sep 26, 2018]

Researchers from the Technical Institute of Physics and Chemistry recently made a deep observation of the 3D fine structures and the entire unzipping process of feathers by using microscopy with a micro/nano manipulating system and 3D X-ray microscopy. They discovered and characterized a sophisticated mechanism in bird feathers that enhances tear resistance, overturning a centuries-old explanation of how bird feathers work.

Bamboo Shoot Fiber Is Effective in Suppressing High-fat Diet-induced Insulin Resistance[Sep 26, 2018]

Recently, researchers from Xishuangbanna Tropical Botanical garden have previously shown that the insoluble dietary fiber isolated from bamboo shoot Dendrocalamus hamiltonii was the most effective among several commonly consumed dietary fibers in China in suppressing high-fat diet-induced body fat mass accumulation in mice.

Scientists Contrast Dynamics and Trait Controls in First-order Root Compared to Leaf Litter Decomposition[Sep 26, 2018]

Dr. SUN Tao, a researcher from Institute of Applied Ecology, compared long-term (six years) in situ decomposition dynamics of leaf litter and first-order roots (as opposed to a fixed diameter cutoff) across 35 co-occurring woody species of a temperate forest ecosystem.

A Seed Dormancy Gene Undergoes Parallel Selection in Multiple Crops[Sep 25, 2018]

Recently, a team led by Prof. TIAN Zhixi and Prof. CHU Chengcai at Institute of Genetics and Developmental Biology, collaborated with Prof. Scott Jackson from University of Georgia, identified a gene responsible for seed dormancy, representing the first domestication gene that has been subjected to parallel selection in multiple crop families.

Prosthetic Skin to Sense Wind, Rain, and Ants[Sep 25, 2018]

Recently, researchers at Ningbo Institute of Materials Technology and Engineering of Chinese Academy of Sciences described their invention in the journal Science Robotics that a sensor converts pressure from touch to electric signals that, theoretically, could be perceived by the brain.


Chinese Cretaceous Fossil Highlights Avian Evolution[Sep 25, 2018]

A newly identified extinct bird species from a 127 million-year-old fossil deposit in northeastern China provides new information about avian development during the early evolution of flight. Scientists from the Institute of Vertebrate Paleontology and Paleoanthropology reported their study of the well-preserved complete skeleton and feathers of this early bird.
