Down syndrome  is caused by a triple copy of chromosome 21, which leads to a number of cognitive and physical delays. Now researchers from the Sanford-Burnham Medical Research Institute in La Jolla, California, have found a protein that restores the some of the cognitive and behavioral disorders found in the disease.

Mice who were deficient in the SNX27 protein exhibited similar characteristics to mice with Down syndrome—namely, they had fewer glutamate receptors, which are important for learning and memory, the team reported in Nature Medicine on Sunday (March 24). The researchers also showed that in mice with Down syndrome, the protein is blocked by a molecule encoded on chromosome 21, and produced in excess in Down syndrome mice as a re ...

Summer is officially over, and fall has arrived. With this season comes runny noses and doctor visits. Save yourself the time and money, because it's either the common cold or the flu, both of which have no cure other than to rest and endure the discomfort. Luckily, you can be immunized for the flu, but not the cold. In fact, many people battle the cold several times a year, rather than developing a natural immunity towards it, why is that? 

The primary reason that immunity generally does not develop against the common cold is that there is not a single cause of the disease. Over 200 serotypes of viruses, including enteroviruses (previously called rhinoviruses), coronaviruses, and adenoviruses, can cause the symptoms of the common cold. Ther ...
