Intelligent people tend to perform better at school and at work, as numerous studies have shown. But what happens in domains where incentives such as good grades or financial rewards don’t apply, and where socio-economic status is not a significant factor? Wine knowledge is a case in point. Intelligence researcher Maximilian Krolo of Saarland University has investigated whether intelligence can predict the acquisition of deep knowledge in a specialized domain. The findings have now been published in the journal Intelligence & Cognitive Abilities in an article co-authored with Professor of Psychology Timothy C. Bates of the University of Edinburgh.

A new international study led by Concordia researchers finds that stronger brain waves during deep sleep may protect people with Alzheimer’s against cognitive decline associated with elevated levels of the neurotransmitter orexin. The three-year study suggests that sleep quality could help slow disease progression and may offer new avenues for monitoring and treatment. (concordia.ca)
