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 […]
New Research Shows that a Screen-Free Bedtime Routine Helps Young Children to Sleep Better
A world-first randomized controlled trial (RCT) of young children’s screen time shows that reducing screen time in the hour before bedtime improves the quality of young children’s sleep. Screen Use in Young Children It is well established that poor sleep in early childhood is associated with negative outcomes such as health problems, developmental difficulties and […]
Light at the End of the Tunnel for Night Shift Workers
Using circadian lighting, in which artificial lighting is synchronized with natural biological rhythms or a person’s “internal clock,” significantly improves the sleep quality and work performance of night shift workers, a large new study has found. The study is among the first rigorous laboratory experiments to simultaneously examine the effects of circadian lighting on markers […]
