Researchers at the University of Illinois have found that a molecular pathway known to have a role in the progression of bone cancer in humans is also critical to the pathology of skeletal tumors in dogs and cats. Their work could lead to advances in the palliative care of companion animals afflicted with osteosarcoma.

An international team of scientists led by the Wildlife Conservation Society working in Iran has successfully fitted two Asiatic cheetahs with Global Positioning System (GPS) collars, marking the first time this highly endangered population of big cats can be tracked by conservationists. Once found throughout the continent, Asiatic cheetahs now live only in extremely arid habitat on the edges of Iran's Kavir Desert.

Digital atlases of the brains of humans, monkeys, dogs, cats, mice, birds and other animals have been created and posted online by researchers at the UC Davis Center for Neuroscience.

Last year 520 rabid animals were found in North Carolina. As a result, a countless number of unvaccinated cats and dogs had to be euthanized and many people had to undergo expensive preventive treatment for rabies. Experts with the North Carolina Division of Public Health are urging people to avoid these problems by vaccinating their pets against rabies.

Marine iguanas on the Galápagos Islands live without predators - at least this was the case up until 150 years ago. Since then they have been confronted with cats and dogs on some islands of the Archipelago. For scientists, they are therefore a suitable model of study in order to discover if such generally tame animals are capable of adapting their behaviour and endocrine stress response to novel predation threats.
