A night and day difference: Circadian clock may protect aging eyes
by Purdue University Fruit flies give insight into age-related changes in human vision. A team of researchers discovered the circadian clock plays a significant role in protecting eyes from retinal degeneration. The team studied fruit flies, which serve as a good model for the human retina. Vikki Weake, associate professor of biochemistry in Purdue’s College...
Dementia patients struggle to cope with change because of damage to general intelligence brain networks
by University of Cambridge Credit: CC0 Public Domain People with dementia struggle to adapt to changes in their environment because of damage to areas of the brain known as “multiple demand networks,” highly-evolved areas of the brain that support general intelligence, say scientists at the University of Cambridge. There are many different types of dementia,...
