[ Watch the Video: Teens Who Sleep Earlier Perform Better At School ] Lee Rannals for redOrbit.com - Your Universe Online In a study of 2,700 middle and high school adolescents, researchers from the University of California, Berkeley found that those who stay up later are more likely to struggle academically and emotionally. In an analysis of the longitudinal data from the large study group, of which 30 percent reported bedtimes later than 11:30 pm on school days and 1:30 am in the...

Discovery May Accelerate Body's Response To Infection And Autoimmune Disorders
2013-11-08 08:57:46

University of Texas Southwestern Medical Center UT Southwestern Medical Center researchers report that disrupting the light-dark cycle of mice increased their susceptibility to inflammatory disease, indicating that the production of a key immune cell is controlled by the body’s circadian clock. The study published in the Nov. 8 edition of Science identifies a previously hidden pathway by which the body’s circadian clock controls the numbers of key inflammatory cells called...

Tricking Algae's Biological Clock Boosts Production Of Drugs And Biofuels
2013-11-07 13:15:53

Vanderbilt University Tricking algae's biological clock to remain in its daytime setting can dramatically boost the amount of valuable compounds that these simple marine plants can produce when they are grown in constant light. That is the conclusion of a "proof of concept" experiment described in the Dec. 2 issue of the journal Current Biology. The study found that when the biological clocks of cyanobacteria (blue-green algae) were stopped in their daylight setting, the amount of...

VIP Treatment For Jet Lag

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...

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....
