| Self-affirmation may break down resistance to medical screening Posted: 21 Dec 2011 06:13 PM PST People resist medical screening, or don't call back for the results, because they don't want to know they're sick or at risk for a disease. But many illnesses, such as HIV/AIDS and cancer, have a far a better prognosis if they're caught early. How can health care providers break down that resistance?  |
| Do you hear what I hear? Noise exposure surrounds us Posted: 21 Dec 2011 06:12 PM PST Nine out of 10 city dwellers may have enough harmful noise exposure to risk hearing loss, and most of that exposure comes from leisure activities.  |
| Breakthrough in treatment to prevent blindness Posted: 21 Dec 2011 11:07 AM PST A new study shows a popular treatment for a potentially blinding eye infection is just as effective if given every six months versus annually. This randomized study on trachoma, the leading cause of infection-caused blindness in the world, could potentially treat twice the number of patients using the same amount of medication.  |
| How pregnancy changes a woman's brain Posted: 21 Dec 2011 11:06 AM PST We know a lot about the links between a pregnant mother's health, behavior, and moods and her baby's cognitive and psychological development once it is born. But how does pregnancy change a mother's brain?  |
| Prejudice comes from a basic human need and way of thinking, new research suggests Posted: 21 Dec 2011 11:06 AM PST Where does prejudice come from? Not from ideology, say the authors of a new article. Instead, prejudice stems from a deeper psychological need, associated with a particular way of thinking. People who aren't comfortable with ambiguity and want to make quick and firm decisions are also prone to making generalizations about others.  |
| How the brain cell works: A dive into its inner network Posted: 21 Dec 2011 11:05 AM PST Scientists are developing the first systematic survey of protein interactions within brain cells. The team is aiming to reconstruct genome-wide in situ protein-protein interaction networks within the neurons of a multicellular organism.  |
| We are natural born multi-taskers Posted: 21 Dec 2011 11:04 AM PST Scientists have found that we are natural-born multi-taskers. They found evidence that we can pay attention to more than one thing at a time.  |
| How normal cells fuel tumor growth Posted: 21 Dec 2011 07:58 AM PST A new study has discovered how normal cells in tumors can fuel cancer progression. The study examines what happens when normal cells called fibroblasts in tumors lose an important tumor-suppressor gene. The findings suggest new strategies for controlling tumor growth, they provide insight into the mechanisms that control the co-evolution of cancer cells and their surrounding normal cells in tumors, and they demonstrate how this gene normally suppresses cancer development.  |
| Do our medicines boost pathogens? Posted: 21 Dec 2011 06:17 AM PST Scientists have discovered a parasite that not only had developed resistance against a common medicine, but at the same time had become better in withstanding the human immune system. With some exaggeration: Medical practice helped in developing a superbug. For it appears the battle against the drug also armed the bug better against its host.  |
| Posted: 21 Dec 2011 06:17 AM PST Sensitivity to allopregnanolone, a hormone that occurs naturally in the body after ovulation and during pregnancy, changes during the course of the menstrual cycle and is different in women with severe PMS compared with women without PMS complaints.  |
