Two progressively degenerative diseases, amyotrophic lateral sclerosis (ALS, commonly known as Lou Gehrig’s disease) and frontotemporal dementia (FTD, recently in the news with the diagnoses of actor Bruce Willis and talk show host Wendy Williams), are linked by more than the fact that they both damage nerve cells critical to normal functioning — the former affecting nerves in the brain and spinal cord leading to loss of movement, the latter eroding the brain regions controlling personality, behavior and language.
For the first time, researchers at the University of Minnesota Twin Cities showed that non-invasive brain stimulation can change a specific brain mechanism that is directly related to human behavior.

Researchers use the Spruce and Peatland Responses Under Changing Environments (SPRUCE) experiment to warm air and soil in a northern Minnesota bog to simulate the effects of climate change on the carbon cycle. The experiments showed that all organic soil components can break down more quickly in warmer conditions.
