Taller horses are more prone to exercise intolerance

A common cause of exercise intolerance in horses is equine recurrent laryngeal neuropathy (RLN). This is a fancy way of saying that the animals are not able to open their larynx on the left side very well during strenuous exercise, which limits their oxygen intake and ability to exercise. Larger horses, like thoroughbreds, are more prone to developing this condition than smaller breeds. In a new study published in Physiological Genomics […]

Drosophila help researchers understand rare genetic disorder

Barth Syndrome is a rare genetic disorder that affects mainly males. It is characterized by impaired lipid metabolism, muscle weakness, growth delays, cardiomyopathy, and low numbers of neutrophils in the blood, which renders patients with the condition more susceptible to infections. There is no known cure for Barth Syndrome. In the past, patients with Barth syndrome often died by the age of three from infections or heart failure (Barth Syndrome […]

Genetically-modified virus stops Alzheimer’s disease

Check out this video from Reuters (via YouTube). It summarizes an exciting study from researchers at Imperial College London who were able to stop the progression of Alzheimer’s disease in mice by administering a modified virus to the animals. The virus worked by preventing the formation of the characteristic amyloid plaques that are responsible for causing damage to neurons in the brain. Importantly, the virus did not result in loss […]
