On Saturday, May 6, 20 horses will have the chance to compete in the 143rd running of the Kentucky Derby. Like all athletes, these elite Thoroughbreds—under the care of their trainers and owners—must walk the line between rigorous training and injury.

Named for Friedrich Best, who characterized the disease in 1905, Best disease, also known as vitelliform macular dystrophy, affects children and young adults and can cause severe declines in central vision as patients age. The disease is one in a group of conditions known as bestrophinopathies, all linked to mutations in the BEST1 gene.

It’s spring in Philadelphia, which means it’s time to celebrate science. The Philadelphia Science Festival is back next week for nine days of STEM-filled fun. All told, members of the Penn community will be presenting some 45 talks and activities in 14 venues across the city.

Many factors go into evaluating the prognosis of a critically ill animal, usually involving a combination of objective metrics, such as blood pressure or blood oxygenation, and more subjective clinical signs, such as alertness or lethargy.
