Diverse Activity Patterns Of Birds During The Arctic Breeding Season
2013-06-19 11:17:58

Max-Planck-Gesellschaft Our internal circadian clock regulates daily life processes and is synchronized by external cues, the so-called Zeitgebers. The main cue is the light-dark cycle, whose strength is largely reduced in extreme habitats such as in the Arctic during the polar summer. Using a radiotelemetry system a team of researchers from the Max Planck Institute for Ornithology have now found, in four bird species in Alaska, different daily activity patterns ranging from strictly...

Urban Blackbirds Have Faster Circadian Rhythms Than Rural Relatives
2013-06-19 10:27:24

Brett Smith for redOrbit.com - Your Universe Online For years we have known about the differences between city slickers and country bumpkins, but a new study from the Max Planck Institute in Germany has shown that the different environments can have different effects on an organism´s natural biological rhythms. Along with ornithologists from the University of Maine and the University of Glasgow in Scotland, the Max Planck researchers studied the circadian rhythm of both urban and...

Shift Work May Affect Sleep Patterns In Offshore Workers
2013-05-31 13:47:23

Michael Harper for redOrbit.com — Your Universe Online Working long and late shifts on an offshore oil rig can affect your circadian rhythm, creating sleep troubles, says a new study from the University of Bergen (UiB) in Norway. While this seems like commonly understood logic, researcher Siri Waage with the UiB´s Department of Global Public Health and Primary Care says that the long hours and late nights don´t have the same effect on oil workers on dry land. She studied...

Pineal Gland
2013-04-30 10:31:18

The pineal gland, also called the epiphysis cerebri, is an endocrine organ located in the brain. Its primary function is to regulate the sleep cycle and influence sexual development. It is a reddish-gray glandular structure that forms the roof of the third ventricle in the brain, between the two lateral ventricles, tucked in a groove near the thalamic bodies. Its body is relatively the size of a grain of rice; it’s shaped like a pine cone and has an infindibular stalk projecting from it....
