Disruption of the circadian rhythm, which naturally changes on a 24-hour cycle, has been linked to heart disease, but it is unclear how this leads to the condition. A research team at Baylor College of Medicine and collaborating institutions investigated the function of the protein Rev-erbα/β, a key component of the circadian clock, in the […]
Humans are Seasonal Creatures, in Accordance With their Circadian Rhythm
It may be tempting to believe that humanity, with its sophisticated lighting, has outgrown the natural influence of sunlight on its sleeping habits. However, new research from the University of Michigan shows that our circadian rhythm is still fundamentally untamable and follows the seasonal changes in daylight. Circadian Rhythms and Seasonal Changes “Humans are truly […]
The Role of Stress and Depression in Insomnia and Heavy Alcohol Consumption
Insomnia and risky drinking are so closely intertwined that it is estimated that at least one-third and up to 91% of all people who suffer from sleep disorders also consume alcohol heavily. A new study suggests that perceived stress and depression play a role in the relationship between the two conditions—which is perhaps not surprising. […]
How Scientists Developed Cells for Measuring Time
Scientists at UC Merced have developed artificial cells that can measure time perfectly – similar to the 24-hour biological clock in living organisms. By reconstructing the circadian mechanism in tiny vesicles, the researchers were able to show that even simplified synthetic systems can glow in a daily rhythm – provided they have enough proteins. A […]
Do You Have Trouble Falling Asleep or Wake Up in the Middle of the Night? This Could Increase Your Risk of Dementia
Recent research findings add to the growing body of evidence linking sleep disorders to cognitive impairment and show significant associations between three measures of sleep disorders and the risk of developing dementia within ten years. The findings, published in Elsevier’s American Journal of Preventive Medicine, link difficulty falling asleep (taking more than 30 minutes to […]
