Scientists have developed a new system to study Creutzfeldt-Jakob disease in the laboratory, paving the way for research to find treatments for the fatal brain disorder. The study is published in the Journal of Experimental Medicine and was funded by the National Centre for the Replacement, Refinement & Reduction of Animals in Research (NC3Rs).
Each year about 25% of all workers will be confronted potentially traumatic events, such as crime, accidents, serious illness or death of a significant other.

Among the countries in sub-Saharan Africa, Uganda is where cholera remains a recurring problem, despite advances in science and technology for prevention, detection and treatment of the infectious disease.

Scientists developed an innovative approach to deliver drugs, via a micro-needle patch, with drugs that are known to turn energy-storing white fat into energy-burning brown fat. It reduced weight gain in mice on a high-fat diet and their fat mass by more than 30% over four weeks. The findings published in the journal Small Methods.
