Living near major roads linked to risk of dementia, Parkinson’s, Alzheimer’s and MS
Living less than 50 meters away from a major road, or less than 150 meters away from a highway, increases the risks for dementia, Alzheimer's disease, Parkinson's disease, and multiple sclerosis. However, living close to green spaces appears to have more of a protective effect against neurodegenerative diseases.... Read More...
A rat had basically no brain, but it could still see, hear, smell, and feel
Rat R222 was born with hydrocephalus. Neuroimaging revealed most of its brain had compressed and collapsed as it filled with fluid. However, despite its condition, the animal was still able to see, hear, smell, and feel like other animals. The study sheds new light on neuroplasticity, and the findings could have implications for the development of new machine learning technologies.... Read More...
