• Scientists discover how the brain repurposes itself to learn scientific concepts

  12-04-2016 19:26
  The human brain was initially used for basic survival tasks, such as staying safe and hunting and gathering. Yet, 200,000 years later, the same human brain is able to learn abstract concepts, like momentum, energy and gravity, which have only been formally defined in the last few centuries. New research has now uncovered how the brain is able to acquire brand new types of ideas.

• Tissue biomarker for dementia with Lewy bodies and Parkinson’s disease

  12-04-2016 15:10
  Accurate diagnosis of Parkinson's disease, and the related disease "dementia with Lewy bodies," can be difficult in the early stages of both conditions. While brain biopsies can be more accurate, the risk of complications has been considered too high. New research indicates that a biopsy of the submandibular gland can help identify the same pathology that is seen in the brain, providing some of the increased accuracy of brain biopsy, but not the increased risk.
