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...

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....
