The study used functional MRI to measure brain activity in a specific region, the dorsal anterior cingulate cortex, which was found to work harder in individuals with lower sleep efficiency.
A study of 35 popular phone-based sleep apps found that most help users set sleep-related goals and track their sleep patterns, but few provide general information about sleep or its benefits. The analysis suggests that there is room for improvement in the development of these apps to educate users about the importance of sleep.

A recent study has identified a gene mutation as the cause of delayed sleep phase disorder (DSPD), a common sleep disorder affecting up to 10% of the public. The CRY1 protein plays a crucial role in regulating the circadian clock, and a single-point mutation can lead to prolonged sleep onset times and irregular sleep patterns.
Researchers at Rockefeller University discovered a genetic mutation in the CRY1 gene that slows the internal biological clock, causing delayed sleep phase disorder. The mutation affects up to 1 in 75 people and can be present in families, with relatives sharing similar signs of persistent sleep problems.

A recent study links adolescent sleepiness to future crime rates, with sleepy teens more likely to commit crimes by age 29. The study suggests that poor daytime attention and social adversity may contribute to the relationship between sleepiness and crime.
Research from the University of Pennsylvania and University of York found that teenagers who self-report feeling drowsy mid-afternoon are 4.5 times more likely to commit violent crimes a decade and a half later. The study also links daytime sleepiness with poor attention and brain function, which can lead to criminal behavior.

The study suggests that architectural design can incorporate tunable lighting to enhance performance and well-being.
A four-year research project published in Science offers a direct visual proof of the synaptic homeostasis hypothesis, which suggests that sleep is essential for brain plasticity and learning. The study found that synapses in mice brains shrink by nearly 20% during sleep, creating room for growth and learning the next day.
A weekend camping trip can reset people's internal clocks rapidly, regardless of season, by increasing daytime exposure to sunlight and reducing nighttime electrical lighting. This helps to shift melatonin levels and improves sleeping patterns.
Two studies reveal that synapses shrink after mice sleep, only to grow again upon waking, suggesting a balance mechanism between activity and rest. A gene called Homerla plays a role in synaptic weakening during sleep by remodeling a molecular signaling complex.

A study published in eLife reveals that a single nerve cell named ALA coordinates an organism-wide response to sickness, causing sleepiness by releasing FLP-13 and other neuropeptides. Researchers found that FLP-13 triggers sleep by turning down activity in nervous system cells that help keep organisms awake.
