Proper Methionine Supplementation During Late Gestation Could Enhance Reproductive Performance of Sows[Oct 18, 2018]

To validate the hypothesis that different levels of maternal dietary methionine can change antioxidant capacities and thus fetal growth and development during the late gestation period, researchers in the Institute of Subtropical Agriculture evaluated the effects of dietary methionine, administered during the late gestation period, on the production performance of sows.

Scientists Reveal Enrichment Mechanism of Light Mg Isotopes by Mg-depleted Clay Minerals and Fe Oxides[Oct 18, 2018]

To explore the mechanisms controlling the Mg isotopic compositions of Fe-Mn nodules and surrounding soil, Prof. LIU Chengshuai from the Institute of Geochemistry systematically investigated the Mg isotopic compositions of Fe-Mn nodules, surrounding soils, soil waters, and soil surface waters in a paddy soil profile, and stream waters, and rainwaters from south China.

Mouse Pups with Same-sex Parents Born in China Using Stem Cells and Gene Editing[Oct 18, 2018]

Researchers at Institute of Zoology were able to produce healthy mice with two mothers that went on to have normal offspring of their own. Mice from two dads were also born but only survived for a couple of days.

New Findings Provide Insights into Adaptive Evolution of Marine Organism[Oct 18, 2018]

A research group led by Prof. ZHANG Guofan from the Institute of Oceanology and its collaborators reported their findings in adaptive evolution of one marine organism. Their findings provide insights into how marine populations adapt and diverge under complex conditions, and contribute to the understanding of the evolutionary potential of marine organisms under rapid climate change as well as evaluation of genetic resources for conservation and sustainable ecosystem services.

How Do Tree Species Respond to Grass Competition in Savannas?[Oct 18, 2018]

Researchers from Xishuangbanna Tropical Botanical Garden and their collaborators conducted a study to investigate how tree species differ in response to competition from grasses and nutrient supply. They further wanted to see whether the responses can be related to plant traits.

Oscillations Provide Insights into the Brain's Navigation System[Oct 17, 2018]

The brain creates a map of our environment, which enables reliable spatial navigation. The Nobel Prize was awarded in 2014 for research into how this navigation system works at the cellular level. Researchers have now shown that the characteristics of this navigation system are also present in brain oscillations that can be measured using depth electrodes in the human brain. The possibility of testing the neuronal navigation system in this way may open up new approaches for the early diagnosis of Alzheimer's disease.
