The Simplest of Slumbers (13 minute read)

This article describes several sleep studies in animals to explore the nature of sleep. There is a lot of variation in how different animals sleep. Animals with brains consolidate memories, flush out toxic waste, and strengthen connections between nerve cells during sleep. Animals without brains seem to also need sleep, suggesting that sleep plays a deeper role in preserving basic physiological processes. The study of sleep in brainless creatures is controversial, but new data shows that even the earliest lifeforms show signs of sleep.

Researchers boost human mental function with brain stimulation (3 minute read)

A team of scientists created a system that targets a brain region with small amounts of electrical energy to improve mental function. It is the first time that scientists have been able to reliably enhance a specific human mental function linked to mental illness. The system could provide a new approach to treating mental illness, where instead of suppressing symptoms, patients can use tools to take control of their own minds. Clinical trials are set to begin soon.
