And studies find it’s something almost everyone will have to e ...read more

The similarities between koalas and Nimbado ...read more

Some of us may even look forward to sleep — and the adventures we’ll go on in our dreams. What is it about people who don’t remember their dreams that set them apart from the people who do? Is it possible for the brain to stop producing dreams? And could something be wrong in the brains of people who report never dr ...read more

The reason behind this phenomenon is much simpler: It’s the result of evolutionary mechanisms which allow certain species to see better in the dark.Why Do ...read more
