Millions of people worldwide suffer from obstructive sleep apnea, a common condition in which breathing is repeatedly interrupted during sleep. New research in mice suggests that gut microbes and the metabolites they produce may play a surprising role in protecting against some of the most serious consequences of this condition, including heart disease. The findings […]Millions of people worldwide suffer from obstructive sleep apnea, a common condition in which breathing is repeatedly interrupted during sleep.

Scientists Discover a Neurotransmitter that Helps People Break Bad Habits
Whether you’re acing a job interview, meeting someone for the first time, or responding to an unexpected challenge—success often depends on how well you can adapt your behavior. In some situations, adapting quickly can even be a matter of survival. But how does the brain know when it’s time to abandon an old strategy and […]Whether you’re acing a job interview, meeting someone for the first time, or responding to an unexpected challenge—success often depends on how well you can adapt your behavior.

How a Hair Sample Decodes the Body’s Internal Clock
A research team at Charité – Universitätsmedizin Berlin has developed a method for determining a person’s individual internal clock using just a few hair follicles. The results, published in the journal PNAS, are considered a significant advance for the field of circadian medicine. This field of research examines how biological daily rhythms influence health, disease, […]A research team at Charité – Universitätsmedizin Berlin has developed a method for determining a person’s individual internal clock using just a few hair follicles.

Caffeine Counteracts Memory Problems Caused by Lack of Sleep
Researchers at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS Medicine) have found that caffeine can help restore a specific type of memory that is impaired by sleep deprivation. The findings, published in Neuropsychopharmacology, show how caffeine acts on a specific brain pathway involved in social memory—that is, the […]Researchers at the Yong Loo Lin School of Medicine at the National University of Singapore (NUS Medicine) have found that caffeine can help restore a specific type of memory that is impaired by sleep deprivation.

Chronobiology in the Lab: Researchers Reconstruct an Artificial Biological Clock
Every morning, a precisely coordinated biological program begins in the human body. Even before we are fully awake, cortisol levels rise, body temperature changes, metabolism is activated, and certain genes are switched on while others are shut down. At night, on the other hand, repair processes take place, the immune system functions differently, and the […]Every morning, a precisely coordinated biological program begins in the human body.
