Researchers from Chalmers and the University of Gothenburg have shown that nanocellulose stimulates the formation of neural networks. This is the first step toward creating a three-dimensional model of the brain. Such a model could elevate brain research to totally new levels, with regard to Alzheimer's disease and Parkinson's disease, for example. Over a period of two years the research group has been trying to get human nerve cells to grow on nanocellulose.
"This has been a great challenge," says Paul Gatenholm, Professor of Biopolymer Technology at Chalmers.‟Until recently the cells were dying after a while, since we weren't able to get them to adhere to the scaffold. But after many experiments we discovered a method to get them to attach to the scaffold by making it more positively charged. Now we have a stable method for cultivating nerve cells on nanocellulose."
When the nerve cells finally attached to the scaffold they began to develop and generate contacts with one another, so-called synapses. A neural network of hundreds of cells was produced. The researchers can now use electrical impulses and chemical signal substances to generate nerve impulses, that spread through the network in much the same way as they do in the brain. They can also study how nerve cells react with other molecules, such as pharmaceuticals. Continue to read: sciencedaily.com

Coffee may reduce diabetes risk

The consumption of coffee does not increase the risk of heart disease and may reduce the risk of developing diabetes by up to 30%, says results of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Read more: nutraingredients-usa.com
