Although it is known that sleep improves cognitive performance, the underlying neural mechanisms, especially in the context of non-REM sleep, are still largely unexplored. A new study by a team of researchers from Rice University and Houston Methodist’s Center for Neural Systems Restoration and Weill Cornell Medical College, coordinated by Valentin Dragoi of Rice University, […]
How Jet Lag Can Negatively Affect Your Metabolism
Have you ever felt sluggish and uncomfortable after a long-haul flight or a night shift? A new study by the University of Surrey and the University of Aberdeen has shown that disruptions to our internal clock, such as those that occur with jet lag, affect our metabolism – albeit to a lesser extent than fatigue […]
Cellular Aging in One Organ Can Lead to Multiple Organ Failure
The aging and malfunctioning of cells that occurs when one part of the body is damaged can spread to other organs, a study has found. Scientists have shown for the first time that cell damage in a damaged liver can trigger a process associated with aging and dysfunction, and then spread to otherwise healthy organs […]
Brighter Nights and Darker Days Could Lead to an Early Death
A study analyzing data from more than 13 million hours of light sensor data collected from 89,000 people has found that exposure to light nights and dark days is associated with an increased risk of mortality. Bright light at night disrupts the body’s normal day-night cycle, known as the circadian rhythm, and can lead to […]
Anxiety and Depression: The Role of the Amygdala
Treatment for anxiety, depression and other disorders may depend on the amygdala, a part of the brain that controls strong emotional responses, particularly fear. Until now, however, there has been a lack of in-depth understanding of this structure. Now, scientists at the University of California, Davis, have identified new cell clusters with distinct gene expression […]
