In states where medical exemptions from vaccination requirements for kindergarten students are easier to get, exemption rates are higher, potentially compromising herd immunity and posing a threat to children and others who truly should not be immunized because of underlying conditions, according to a new study.
Researchers have identified a way in which men can develop prostate cancer after contracting trichomoniasis, a curable but often overlooked sexually transmitted disease. Previous studies have teased out a casual, epidemiological correlation between the two diseases, but this latest study suggests a more tangible biological mechanism.
Blue tits, a familiar garden bird in the U.K., could be the salvation of our imperiled conker trees (horse-chestnut trees), which are under severe attack by a tiny non-native moth that has spread from continental Europe.
Alzheimer's disease (AD) is one of the most common brain disorders, with an estimated 35 million people affected worldwide. In the last decade, research has advanced our understanding of how AD affects the brain. However, diagnosis continues to rely primarily on neuropsychological tests which can only detect the disease after clinical symptoms begin.
Scientists have opened a new front against the cause of sleeping sickness. This parasite is transmitted between humans by tsetse flies. The researchers learned a bacterium living in those flies how to produce antibodies against the parasite. Application in the field is still a long way of, but the technique shows quite some promise.
(Phys.org)—Proteins embedded in the lipid membranes of cells feel long-range attractive forces in specific patterns that mediate the proteins' behavior—for example, assisting in the clumping sequences in response to allergens, such as pollen, that eventually lead to the inevitable sneeze.
Chronic stress, prompted by major life stressors and type A personality traits, is linked to a high risk of stroke, new research finds.
Smoking more than 20 cigarettes a day doubles the risk of a potentially fatal brain bleed as a result of a burst aneurysm, new research finds.
Standard head movements made while exposed to one of the three electromagnetic fields produced by a heavy duty MRI scanner seem to temporarily lower concentration and visuospatial awareness, an experimental study shows.
Despite nearly three decades of conflict, Sri Lanka has succeeded in reducing malaria cases by 99.9 percent since 1999 and is on track to eliminate the disease entirely by 2014.
Scientists are closer to establishing a definitive bacterial cause for the skin condition rosacea. This will allow more targeted, effective treatments to be developed for sufferers.
One of the largest studies to look at the effect of induced abortions on a subsequent first birth has found that women who have had three or more abortions have a higher risk of some adverse birth outcomes, such as delivering a baby prematurely and with a low birth weight.
