New research led by Professor Hannes Lohi at the University of Helsinki, Finland, revealed several similarities between compulsive behavior in dogs and humans.  Dogs may turn out to be of significant use in investigating the causes of human psychiatric diseases. "Stereotypic behavior occurs in spontaneously; they share the same environment with humans, and as large animals are physiologically close to humans. Furthermore, their strict breed structure aids the identification of genes."

Even sharks can get a tan. Sharks' skin turns from dark brown to black as the pigment melanin increases in direct response to radiation. In other fish, the exposure can lead to skin cancer. Sharks, however, just seem to tan. What's their secret? The answer could hold the key to preventing skin disease in humans.

A group of Kansas State University researchers has made valuable findings in the search for cancer's cure.  While researching ways to improve animal health, the scientists -- Raymond "Bob" Rowland, a virologist and professor of diagnostic medicine and pathobiology, and Deryl Troyer, professor of anatomy and physiology -- have made two important discoveries that can also improve human health. Not only have they found pigs with severe combined immunodeficiency, or SCID, but they are also the first to discover the connection with human cancer, particularly melanomas and pancreatic cancers.

This week Autism Speaks announced that it initiated and is funding the development of new genetically modified rat models of autism spectrum disorder (ASD). My team at Baylor College of Medicine will help characterize these models in close partnership with the science staff at Autism Speaks and SAGE Labs. These models will provide autism researchers with important new tools for understanding the underlying biology of ASD and testing experimental medicines. Indeed, they will be among the first rat models made widely available to the field of autism research.

The Food and Drug Administration has approved a phase 1 clinical trial to evaluate the safety of transplanting human Schwann cells to treat patients with paralysis. It is the first such trial in the world. In studies done in rats and mice, pigs and in primates, about 70 percent of function and movement was restored to the fully paralyzed animals.
