Musical training, bilingualism, and executive function: working memory and inhibitory control
Early studies suggested the possibility of a cognitive advantage from musical training and bilingualism but have failed to be replicated by recent findings. To assess whether cognitive benefits from training exist, and how unique they are to each training domain, this study compared musicians and bilinguals to each other, plus to individuals who had expertise in both skills, or neither. The findings confirm previous associations between musicians and improved cognition and extend existing evidence to show that benefits are narrower than expected but can be uniquely attributed to music compared to another specialized auditory skill domain.

YouTube Is Removing Some Nootropics Channels
YouTube deleted at least three nootropics channels over the past three days, leaving members of the community confused and worried that a larger crackdown is coming. Apparently this wasn’t targeted, per the updated Motherboard article, but it leaves more questions than answers about YouTube’s enforcement and appeal guidelines.
New Studies Show Dark Chocolate Can Enhance Cognitive And Immune Health
Although doctors have known about dark chocolate’s health benefits for awhile, these new studies are the first to look specifically at the brains and immune systems of human patients. Flavonoids, an antioxidant, are credited with reducing brain and heart inflammation, but these antioxidants aren’t limited to chocolate. They’re also found in dark vegetables and fruits.
Pupils are taking drugs to help them perform well in exams, says Dr Miriam Stoppard
It’s finals season for many college and university students, which means a raft of “smart drugs” articles. Many of these are overblown and designed to create more FUD than fact.
Scientists develop ‘artificial retina’ in hope to restore sight to the blind
A cheap new artificial retina could soon be used to restore sight to the blind. Researchers from Tel Aviv and Linkoping have developed a small, photoactive film capable of converting light into electrical signals that stimulate light-sensitive nerve cells in the eye. It is hoped that the research could lead to the development of a wireless implant which could be inserted in the eye of a person whose light-sensitive cells have degraded. This technology may be adapted for other biological applications.
