A team of scientists, including three researchers at George Mason University, found that the mineral zinc could play a role in the development of macular degeneration. In studying eye tissue samples, the researches found that deposits, that are hallmarks of age-related macular degeneration (AMD), contain large amounts of zinc.
Sheets of highly organized epithelial cells line all the cavities and freesurfaces of the body, forming barriers that control the movement of liquidsand cells in the body organs. The organized structure of normal breastepithelial cells may also serve as a barrier against cancer, according to astudy by University of Helsinki scientists.
Obesity has long been thought to be a major factor in couples’ inability to conceive, but a University of Adelaide researcher has discovered scientific evidence that obesity affects women’s eggs.
As summer comes to a close, many parents are preparing their children to return to school. Any back to school plan will probably include a trip to the doctor or the neighborhood pharmacist to receive vaccinations. While children are commonly vaccinated to protect against chicken pox, measles and polio , one health threat often overlooked is pertussis. The spread of pertussis, also known as the ?whooping cough?, declined after widespread use of the vaccine began during the 1940s. However, since 1990 the illness, characterized by severe coughing, has been on the rise, particularly among older adolescents and adults who may have developed immunity to early vaccinations. Many adults do not realize that they are carriers of the disease. The illness spreads quickly when a sick patient sneezes, coughs or even talks and can have serious consequences for infants and toddlers who are exposed. Until recently, there was no pertussis containing vaccine approved in the United States for adolescents and adults.
For most children and teens, the beginning of a new school year is just around the corner. Not only will they be hitting the books again after a three-month-long summer break, but many of them will also participate in after-school activities. More research is emerging that sheds light on a serious problem affecting student-athletes nationwide: the number of children and teens who are considered obese is rising dramatically.
Humans are social animals even more than was thought, including those suffering from autism and conditions that make it hard to relate to others. Cooperative behaviour is deeply ingrained in nearly all people, but the underlying cognitive processes that make this happen are poorly understood.
A University of Adelaide researcher has discovered scientific evidence that obesity is a key factor in infertility – because of how it affects women’s eggs.
A neuroscientist working at University College London has devised the first experimental method to induce an out-of-body experience in healthy participants. In a paper published today in Science, Dr. Henrik Ehrsson, UCL Institute of Neurology, outlines the unique method by which the illusion is created and the implications of its discovery.
Boys with difficulty reading actually respond better to female teachers, according to a new Canadian study. Research shows that boys develop higher positive self-perceptions as readers when they worked with female research assistants compared to working with male research assistants.
Researchers have found new evidence that soft drinks sweetened with high-fructose corn syrup (HFCS) may contribute to the development of diabetes, particularly in children.
