Washington University in St. Louis A brain chemical that desynchronizes the cells in the biological clock helps the clock adjust more quickly to abrupt shifts in daily light/dark schedules such as those that plague modern life A small molecule called VIP, known to synchronize time-keeping neurons in the brain's biological clock, has the startling effect of desynchronizing them at higher dosages, says a research team at Washington University in St. Louis. Far from being catastrophic,...

A 7W LED bulb that will not suppress the production of melatonin is now available from Photonic Developments LLC at http://www.lowbluelights.com for $ 34.95. This compares with $69.95 for a competing LED good night bulb that only cuts blue light in half. University Heights, OH (PRWEB) October 26, 2013 The interest in reducing blue light in the evening is rapidly increasing with two major lighting companies introducing “healthy” light bulbs. Since 2001 it’s been known that it is...

Plants Keep Time WIth Sugar
2013-10-24 08:38:31

redOrbit Staff & Wire Reports - Your Universe Online Like animals, plants have a 24-hour internal clock, known as circadian rhythm, which allows them to innately maintain track of time. Now, researchers from the University of Cambridge’s Department of Plant Sciences are working to discover exactly how this process works. As Dr. Alex Webb and his colleagues explain in Wednesday’s edition of the journal Nature, weeds, trees, herbs, shrubs and other types of flora are able to...

Dr. Richard Hansler's new book "Pregnant? New Baby? Need Sleep!" describes how avoiding light at night can improve sleep for new mothers and reduce risk of postpartum depression. University Heights, OH (PRWEB) October 15, 2013 Numerous studies show that exposing the eyes to light during the night results in two things, suppressing the production of melatonin, the sleep hormone and in resetting of the circadian or internal clock. New mothers (and fathers) getting up during...

Internal Clock Helps Marine Animals Follow The Tides
2013-09-26 15:39:27

Lee Rannals for redOrbit.com - Your Universe Online Marine animals have an internal clock to help them keep up with their schedules, according to findings published in the journals Current Biology and Cell Reports. The new findings suggest that these animals may be using these clocks as standard operating equipment. "The discovery of the circadian clock mechanisms in various terrestrial species from fungi to humans was a major breakthrough for biology," says Charalambos Kyriacou of the...

Using products from Photonic Developments LLC (https://www.lowbluelights.com) helps new mothers and their babies avoid sleep problems caused by ordinary lighting, according to Dr. Hansler. University Heights, OH (PRWEB) September 25, 2013 Very few women are aware that exposing the eyes to ordinary light when awakened during the night, shuts down the production of melatonin by the pineal gland. This lack of melatonin makes it difficult to fall asleep again after a nighttime awakening. This...

Understanding How Our Seasonal Clocks Work Using Siberian Hamsters
2013-09-24 08:10:52

April Flowers for redOrbit.com - Your Universe Online Humans, and many other animals, have internal clocks and calendars that help them regulate behavior, physiological functions and biological processes. Scientists have extensively studied the mechanisms that inform our daily functions, known as circadian rhythms. However, they know very little about the internal timekeeping mechanisms that inform seasonal functions. A new international study, led by the University of Chicago, reveals...

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....
