Overweight dogs may live shorter lives

New research from the University of Liverpool and Mars Petcare's WALTHAM Centre for Pet Nutrition reveals overweight dogs are more likely to have shorter lives than those at ideal body weights.

Results from the study, conducted retrospectively across two decades and published in the Journal of Veterinary Internal Medicine, revealed the lifespan of dogs that were...

Fruit flies help to shed light on the evolution of metabolism

Diet choice of animal species is highly variable. Some are specialists feeding only on one food source, such as a sugar-rich fruit or protein-rich meat. Other species, like humans, are generalists that can feed on different kinds of food sources.

Because of these differences, animal species ingest different amounts of macronutrients, like carbohydrates and amino acids....

Extraordinary treefrog discovered in the Andes of Ecuador

A new treefrog species was discovered during a two-week expedition to a remote tabletop mountain at Cordillera del Cóndor, a largely unexplored range in the eastern Andes.

"To reach the tabletop, we walked two days along a steep terrain. Then, between sweat and exhaustion, we arrived to the tabletop where we found a dwarf forest. The...

Sound changes the way rodents sense touch

Our eyes, ears and skin are responsible for different senses. Moreover, our brain assigns these senses to different regions: the visual cortex, auditory cortex and somatosensory cortex. However, it is clear that there are anatomical connections between these different cortices such that brain activation to one sense can influence brain activation to another. A new...

Contact with monkeys and apes puts populations at risk

Animal diseases that infect humans are a major threat to human health, and diseases often spillover to humans from nonhuman primates. Now, researchers reporting in PLOS Neglected Tropical Diseases have carried out an extensive social sciences evaluation of how populations in Cameroon interact with nonhuman primates, pointing toward behaviors that could put people at risk...

Historical genomes reveal recent changes in genetic health of eastern gorillas

The critically endangered Grauer's gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations. These conclusions were reached by an international team of researchers who sequenced eleven genomes from eastern gorilla specimens collected up to 100 years ago, and compared these with genomes from present-day individuals. The results are now published...
