April theory: Why molecular changes may boost our moods in spring.
Dr. Joseph Takahashi, one of the world’s leading experts on biological clocks, says spring is when many people who endure seasonal affective disorder begin to feel happier. He says several molecular changes are likely responsible for these mood changes, many…
Circadian rhythms and epilepsy Part II: Dr. Maxime Baud
What percentage of people with epilepsy have rhythms to their seizures? How do anti-seizure medications affect rhythms? Is it possible to manipulate seizure rhythms? In Part 2 of our two-part series on circadian rhythms, Dr. Laurent Sheybani talks with Dr. Maxime Baud.

Education essential for eating well on the night shift
In Australia, one in every five employees are shift workers. But when you work irregular hours, you eat at irregular hours and this can put you at increased risk of weight gain, type 2 diabetes, and cardiovascular disease.
Can the Gut Cope with Night Exercise?
Gut issues are common with endurance exercise, ranging from mild discomfort to severe debilitating symptoms warranting reduced exercise workload or even cessation from activity. Considering the recent exponential growth of nighttime endurance and ultra-endurance events, athletes anecdotally report having more…
Circadian Gene Mutation Increases Self-Administration of Cocaine in Mice
University of Pittsburgh researchers reveal a molecular basis for the deep and fundamental connection between the disruption in circadian rhythms and predisposition to substance abuse.
Sleep and diabetes study receives $3M grant
Getting more sleep, and establishing a regular sleep schedule, is a common recommendation for maintaining and improving health, including for people with Type 1 diabetes. Short sleep patterns may affect how the body uses insulin, and irregular sleep schedules can affect glucose through changes in one’s circadian rhythm or biological clock.
