A new computational model successfully predicts how daily pain sensitivity rhythms affect pain processing, both in healthy adults and in people with neuropathic pain. Jennifer Crodelle of New York University and colleagues present these findings in PLOS Computational Biology.
A study in rats has revealed the presence of naturally occurring DMT, an increasingly popular hallucinogen.
Sleep disturbances and mental health challenges are putting close to half of America's firefighters at high risk of emotional fatigue and exhaustion, new research by Monash University in Australia shows.
Researchers from the University of Copenhagen have learned that the effect of exercise may differ depending on the time of day it is performed. In mice they demonstrate that exercise in the morning results in an increased metabolic response in skeletal muscle, while exercise later in the day increases energy expenditure for an extended period of time.
Preliminary findings from two analyses of an ongoing study suggest that cognitive behavioral therapy for insomnia delivered by telemedicine is as effective as face-to-face delivery.
A simple tweak to the sleeping patterns of 'night owls' -- people with extreme late sleeping and waking habits -- could lead to significant improvements in sleep/wake timings, improved performance in the mornings, better eating habits and a decrease in depression and stress.
According to preliminary results of a new study, there is a high prevalence of insufficient sleep and symptoms of common sleep disorders among medical center nurses.
Preliminary findings from a new study of middle school and high school students suggest that they got more sleep and were less likely to feel too sleepy to do homework after their district changed to later school start times.
A web-based caffeine optimization tool successfully designs effective strategies to maximize alertness while avoiding excessive caffeine consumption, according to preliminary results from a new study.
Cells harbor molecular clocks that generate a circadian oscillation of about 24 h. The cyanobacterial circadian rhythm is regulated by three clock proteins. The research groups at Nagoya City University and National Institutes of Natural Sciences have revealed a sophisticated mechanism of the circadian clock proteins. Their findings have been published in Life Science Alliance.
