Since September 2016, a project entitled "Development of a Global High-resolution Marine Dynamic Environmental Forecasting System" has been funded by the "Program on Marine Environmental Security Guarantee" of the National Key Research and Development Program of China.
Based on publicly accessible data, this project will carry out supplementary observations and experiments; conduct further studies on multi-scale ocean mixing processes; improve the marine physical parameterization scheme; improve the numerical grid, algorithm technology, parallel technology, and coupling technology; and develop a combined global high-resolution ocean circulation model, tidal model, ocean wave model and wave-tide-flow coupling model for operational forecasting.
This project will also develop a pressure-coordinate ocean numerical model, a coupled ocean-atmosphere model, and other new technology from China's own research and development for future operational applications.
These models will be implemented to establish a global high-resolution ocean prediction system, and forecast products will be released, including temperature, salinity, velocity, and ocean wave and tidal currents with a horizontal resolution of 10 km.
The accuracy of these products will reach an advanced international level. The system will clearly identify ocean mesoscale phenomena, with a forecasting validity time of five to seven days.
Thus far, a series of results have been obtained including multi-source ocean observation datasets, the setup of models, vertical mixing parameterization and its mechanism, amongst others.
More information about the project can be found in a recently published report in Atmospheric and Oceanic Science Letters.

The WT1 gene fulfills a central role in the development of a healthy, proper functioning kidney. Mutations in WT1 lead to impairments in kidney development and cause Wilms tumors, a pediatric kidney cancer. Researchers of the Leibniz Institute on Aging – Fritz Lipmann Institute (FLI) in Jena have now discovered a further important function of WT1. It is also active outside the kidneys in the central nervous system and is involved in controlling movement. If the gene is missing in the spinal cord, locomotor aberrancies occur. The results have now been published in Life Science Alliance.
Transcription factor WT1 (Wilms tumor 1) has been known for nearly 30 years and it is significantly involved in the development of a healthy and properly...
A unique feature that sets neurons apart from all other cells are their beautiful, highly elaborate dendritic trees. These structures have evolved to receive the vast majority of information entering a neuron, which is integrated and processed by virtue of the dendrites’ geometry and active properties. Higher brain functions such as memory and attention all critically rely on dendritic computations, which are in turn controlled by inhibitory synaptic input. A team of scientists, led by Johannes J. Letzkus (MPI for Brain Research), now has identified a novel form of inhibition that dominantly controls dendritic function and strongly depends on previous experiences.
Our brain is a remarkably complex system. It is not only comprised of billions of neurons, but each individual neuron by itself even has exceptional processing...

Our brain is a complex network with innumerable connections between cells. Neuronal cells have long thin extensions, so-called axons, which are branched to increase the number of interactions. Researchers at the Max Planck Institute of Biochemistry (MPIB) have collaborated with researchers from Portugal and France to study cellular branching processes. They demonstrated a novel mechanism that induces branching of microtubules, an intracellular support system. The newly discovered dynamics of microtubules has a key role in neuronal development. The results were recently published in the journal Nature Cell Biology.
From the twigs of trees to railroad switches – our environment teems with rigid branched objects. These objects are so omnipresent in our lives, we barely...
