Toddlers learn their first words better from people than from Teletubbies, according to new research at Wake Forest University. Children younger than 22 months may be entertained, but they do not learn words from the television program, said Marina Krcmar, associate professor of communication at Wake Forest and author of the study.
Men and women with multiple sclerosis (MS) equally transmit the genetic risk of the disease to their children, according to a study published June 27, 2007, in the online edition of Neurology?, the medical journal of the American Academy of Neurology.
Scientists have discovered a new type of mouse embryonic stem cell that is the closest counterpart yet to human embryonic stem cells, the National Institutes of Health announced today. The cells are expected to serve as an improved model for human ES cells in studies of regeneration, disease pathology and basic stem cell biology.
A new genetic test targeting the most common types of muscular dystrophy — those caused by mutations in the dystrophin gene — is far quicker with greater accuracy and sensitivity than existing tests. It can be used to confirm clinical diagnoses, to test female family members who may be carriers, and to perform prenatal testing.
A research team led by Dennis W. Metzger, Ph.D., at the Albany Medical College in New York has now shown that treating laboratory mice with a serum containing tularemia-specific antibodies protects the mice against F. tularensis, not only if given before exposure to lethal doses of inhalational F. tularensis but also up to 48 hours after exposure. These findings suggest a possible alternative treatment approach to traditional antibiotics.
Next time you lose your car keys and enlist the family to help you search, try a little experiment. After your spouse searches an area, go and look in the same place. It will likely feel strange, even irritating to both of you – and that?s because you may be fighting an ancient, hard-wired, human behaviour pattern.
Human sperm cells travel up to 6 meters in their transit from testes to penis, and most of that journey occurs in the epididymis, a tightly coiled tube that primes the cells for their ultimate task: fertilization. In a PNAS paper released this week, researchers report that they have discovered a gene — and related mechanism — essential to the embryonic development of the epididymis.
A family-based weight management program developed by researchers at Yale School of Medicine was more effective at reducing weight, body fat, body mass index (BMI) and insulin sensitivity than traditional clinic-based weight counseling.
A unique study by researchers at the University of York and Hull York Medical School has confirmed a link between depression and low levels of folate, a vitamin which comes from vegetables.
