Claims Of Sex-related Differences In Genetic Association Studies Often A review of previous research suggests that prominent claims of sex differences of gene-disease associations are often insufficiently documented and validated, according to a new article. In the human genome era, for many common diseases, published research has often considered that some common gene variants may have different effects in men vs. women. Can You Feel The Heat? Tiny Hair-like Cell Structures, Your Cilia, Can Scientists have found a previously unrecognized role for tiny hair-like cell structures known as cilia: They help form our sense of touch. Cilia, tail-like projections found on the surface of cells, are perhaps best known as molecular flippers that help cells move around. Gamers Rave About PS3 Sony Expo in Honolulu sees gamers drooling over the new PlayStation 3, eager to buy.

[Cool] Florida's Three Major Schools All Lose For the First Time Since For the first time since 1978, the Gators, 'Noles and 'Canes lost on the same day. New Protein Structure Is A First Step Toward Preventing E. Coli Diseas Scientists from the U.S. Department of Energy's Brookhaven National Laboratory and Stony Brook University have determined the two-dimensional crystal structure of a membrane protein involved in the process by which the Escherichia coli (E. coli) bacteria infects a human. This protein structure is a first step to better understanding how an E. coli infection begins, which may lead to information on how to block it.

Unconventional Brain Circuits Offer Clues To Insomnia-obesity Connecti Unconventional wiring of the brain circuits that govern sleep and waking might explain the prevalence of insomnia and the condition's association with obesity, according to new work published in the April issue of Cell Metabolism. Characterized by a chronic inability to fall asleep or remain sleeping, insomnia is estimated to affect one in every eight Americans. By finding ways to interfere with that unconventional wiring, scientists may advance on new treatments for insomnia, the researchers said. Obesity Finding: Chemical Pathway Causes Mice To Overeat And Gain Weig Researchers from the Scripps Research Institute who are studying how body temperature and energy metabolism are regulated have discovered a pathway that appears to play a critical role in the onset of obesity. Further study of the pathway could lead to better understanding of the physiological foundation of obesity in humans and even the discovery of new treatments for the condition. What Does An Airline Traveler Have In Common With A Glowing Fish?
