Trouble falling asleep at night? Chase that daytime light, study shows
A new study reports that college students in Seattle fall asleep later and wake up later in winter, likely because — as the study also found — in winter the students received less daylight exposure. The researcher say that outside in the morning, even on cloudy days, is the best way to prevent this circadian rhythm “delay.”
Permanent daylight saving time would reduce deer-vehicle collisions, study shows
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

NIH researchers decode retinal circuits for circadian rhythm, pupillary light response
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).

How Did 500 Species of a Fish Form in a Lake? Dramatically Different Body Clocks
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.

Chemo for glioblastoma may work better in morning than evening
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.
