If you don't sleep well during a full moon, it is not because you have epigenetically become a werewolf after watching "Twilight" too many times, lunar cycles and human sleep behavior are connected, according to results of a study on endogenous rhythms of circalunar periodicity.

Prof. Christian Cajochen of the Psychiatric Hospital of the University of Basel and colleagues analyzed the sleep of over 30 volunteers in two age groups in the lab. While they were sleeping, the scientists monitored their brain patterns, eye movements and measured their hormone secretions.

Removing ovaries during hysterectomies protects against future risk of ovarian cancer but the ovaries and the hormones they produce may have advantages for preventing heart disease, hip fracture, sexual dysfunction, and cognitive decline. Outside cancer risk, the most important factor that should determine ovarian conservation vs. removal is her age- whether she is older or younger than 50 - according to a review article published in Journal of Women's Health.

Perceived weight discrimination, or the real kind, may increase risk for obesity, according to survey results published by Dr. Angelina Sutin of the Department of Medical Humanities&Social Sciences, and Professor Antonio Terracciano, Department of Geriatrics researcher who focuses on how psychological traits and genetic factors contribute to physical and mental health, both from the Florida State University College of Medicine in Tallahassee.

Researchers have identified new genetic mutations in the gene KCNK3 that can cause pulmonary arterial hypertension, a rare fatal disease characterized by high blood pressure in the lungs.

The
KCNK3
 mutations appear to affect potassium channels in the pulmonary artery, a mechanism not previously linked to the condition. Cell culture studies showed that the mutations' effects could be reversed with a phospholipase inhibitor.   The effects of the KCNK3 mutations were reversed in cell cultures with an experimental phospholipase inhibitor called ONO-RS-082. 

Newly published research reveals that aberrant signaling by a protein called transforming growth factor-beta (TGF-beta - already known for its role in some connective tissue disorders) is also a potent player in many types of allergies. 

Scientists have long understood that allergies are the result of a complex interplay between environment and genes, but now, in what investigators call a scientific first, a single genetic pathway has been implicated in an array of allergic disorders. 

When most people think 'green' in America, they think of liberal Democrats. It's a carefully crafted image. Conservatives who deny global warming conserve energy just as much as liberals who accept it but that gets little attention. Sociologists in a new paper instead found that the idea of the 'green' Christian is the environmental trope they need to spend their time debunking.

Who ever guessed that sugar could be the downfall of the Bubonic Plague?

Diagnosing the presence of Yersinia pestis, the cause of the zoonotic disease also called the Black Death, may soon be much faster thanks to a simple, inexpensive and reliable glycomics  method of detecting the bacterium. 

A new study by astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have discovered columns of cold, dense gas exiting the disk of nearby starburst galaxy NGC 253, also known as the Silver Dollar Galaxy.

NGC 253 is located 11.5 million light-years away in the constellation Sculptor. The galaxy, with its slightly askew orientation, offers astronomers an uncommonly clear view of several super star clusters near its center. These clusters denote areas where new stars are forming and they also mark the starting point for material being ejected from the galaxy.
