Newly described horned dinosaur from New Mexico was the earliest of its kind

With a frilled head and beaked face, Menefeeceratops sealeyi lived 82 million years ago, predating its relative, Triceratops. Researchers including Peter Dodson, of the School of Veterinary Medicine, and Steven Jasinski, who recently earned his doctorate from the School of Arts & Sciences, describe the find.

In Peru, a race to vaccinate dogs as two epidemics collide
Person kneeling on ground while their dog is vaccinated on a sidewalk in Peru, the medical workers are wearing PPE and working in a temporary plastic tent bubble to protect against COVID.

Vaccinators in Arequipa reported feeling safer within the booths compare to using only PPE. During a pandemic, reduced workforce meant hiring nonmedical personnel to perform vaccinations, so PPE protocols were harder to follow. (Image: Penn Medicine News)

A mutation in the NPHP5 gene leads to a severe blinding disorder, Leber congenital amaurosis. Dogs with the condition that were treated with a gene therapy regrew normal, functional cone cells, labeled in red, that had previously failed to develop. The treatment led to a recovery of retinal function and vision. (Image: Courtesy of Gustavo Aguirre and William Beltran)

Turning back the clock on a severe vision disorder

Gene therapy triggered the regrowth of healthy photoreceptor cells and restored vision in dogs with a severe form of Leber congenital amaurosis.
