Adopting permanent DST in the United States would reduce deer-vehicle collisions and likely prevent an estimated 36,550 deer deaths, 33 human deaths, 2,054 human injuries and $1.19 billion in costs each year. Deer-vehicle collisions would decrease under permanent DST because skies would be brighter later in the evening

Newly published research from RUSH in the journal SLEEP sheds light on how adolescents can get more shut-eye.
In a new University of California, Irvine-led study, researchers define how the circadian clock influences cell growth, metabolism and tumor progression. Their research also reveals how disruption of the circadian clock impacts genome stability and mutations that can further drive critical tumor promoting pathways in the intestine.
The eye’s light-sensing retina taps different circuits depending on whether it is generating image-forming vision or carrying out a non-vision function such as regulating pupil size or sleep/wake cycles, according to a new mouse study from the National Eye Institute (NEI) and the National Institute of Mental Health (NIMH).

There is a long-held belief that having your pet sleep on the bed is a bad idea. Aside from taking up space, noisy scratching, or triggering allergies, the most common assertion averred that your furry companion would disrupt your sleep.
A new study in the journal Sleep finds that increased evening screen time during the Covid-19 lockdown negatively affects sleep quality. During the lockdown period in Italy, daily internet traffic volume almost doubled compared to the same time in the…
Hillary Rowe and Jennifer McGrath say their study upends common beliefs about sharing the bed with four-legged friends
The biological clock is present in almost all cells of an organism. As more and more evidence emerges that clocks in certain organs could be out of sync, there is a need to investigate and reset these clocks locally. Scientists…
Rough night of sleep? Relying on caffeine to get you through the day isn’t always the answer, says a new study from Michigan State University. Researchers from MSU’s Sleep and Learning Lab, led by psychology associate professor Kimberly Fenn, assessed…

Despite the dramatic difference between day and nightlife, how fish exploit different times of day has not been studied systematically. Scientists explored alterations in the circadian timing of activity and the duration of rest-wake cycles in Lake Malawi’s cichlids and identified the first single nocturnal species. Timing and duration of rest and activity varies dramatically, and continuously, between populations of Lake Malawi cichlids, providing a system for exploring the molecular and neural basis underlying variation in nocturnal activity.
New research led by investigators from Boston Medical Center and Grady Memorial Hospital demonstrates the significant decline in hospitalizations for neurological emergencies during the COVID-19 pandemic. The rate of Subarachnoid hemorrhage (SAH) – bleeding in the space between the brain…
An aggressive type of brain cancer, glioblastoma has no cure. Patients survive an average of 15 months after diagnosis, with fewer than 10% of patients surviving longer than five years. While researchers are investigating potential new therapies via ongoing clinical trials, a new study from Washington University in St. Louis suggests that a minor adjustment to the current standard treatment — giving chemotherapy in the morning rather than the evening — could add a few months to patients’ survival.
DARIEN, IL – Four members of the American Academy of Sleep Medicine have been selected as 2021 AASM awards recipients for their contributions to the field of sleep medicine. This year’s award winners will be recognized during the plenary session…

The clinical research conducted through the Center will investigate how to use light to improve people’s lives by stabilizing their circadian rhythms, the natural internal clock that regulates the body’s sleep-wake cycle. Researchers will study how light, either from daylight or electric indoor light, affects circadian rhythms in various populations, from the very young to the very old, including patients with COVID-19, cancer, Alzheimer’s disease, depression, and other illnesses. The goal is to help abate symptoms and improve their sleep, mental health, and cognition.

Sleep cycles in people oscillate during the 29.5-day lunar cycle: In the days leading up to a full moon, people go to sleep later in the evening and sleep for shorter periods of time. Scientists observed these oscillations in urban and rural settings — regardless of an individual’s access to electricity.
