  • iconThe growing trend of emotional support animals
    Emotional Support Animals (ESAs) are showing up in places previously understood to be animal-free. The growing trend includes 'certifying' animals to provide emotional assistance to a person with a diagnosable mental condition or emotional disorder. New research outlines the ethical challenge and offers possible solutions to better serve both people who feel they need ESAs and those who must comply with the animals.
  • iconIntense look at La Brea Tar Pits explains why we have coyotes, not saber-toothed cats
    The most detailed study to date of ancient predators trapped in the La Brea Tar Pits is helping Americans understand why today we're dealing with coyotes dumping over garbage cans and not saber-toothed cats ripping our arms off.
  • iconFearing cougars more than wolves, Yellowstone elk manage threats from both predators
    Wolves are charismatic, conspicuous, and easy to single out as the top predator affecting populations of elk, deer, and other prey animals. However, a new study has found that the secretive cougar is actually the main predator influencing the movement of elk across the winter range of northern Yellowstone National Park.
  • iconCancer without end? Discovery yields fresh insights
    Scientists describe the evolutionary dynamics of a sexually transmitted cancer affecting dogs, which arose in a single ancient animal, living as much as 8.5 millennia ago. The findings provide fresh insights into disease evolution relevant to human cancer study and treatment.

    Pet cats can recognize their own names if their names are used regularly by their owners, according to new results. Projects to understand simple social behaviors like name recognition in cats may give clues to how we humans became social. Both humans and cats have evolved through the process of self-domestication, where the population rewards certain traits that then become increasingly common in future generations.
  • iconFirst reported UK case of likely dog-to-dog transmission of leishmaniosis
    Veterinary professionals have sounded the alarm in this week's Vet Record after treating the first UK case of a dog with the potentially fatal infection, leishmaniosis, that is thought to have been passed on by another dog, rather than by travel to an area where the infection is endemic.
  • iconPoll: Pets help older adults cope with health issues, get active and connect with others
    Pets help older adults cope with mental and physical health issues, according to a new national poll. But pets can also bring concerns, and some people may even put their animals' needs ahead of their own health, the poll finds. Three-quarters of pet owners aged 50 to 80 say their animals reduce their stress and give them a sense of purpose. But 18 percent also said having one puts a strain on their budget.
  • iconSleepovers reduce stress in shelter dogs
    Foster care provides valuable information about dog behavior that can help homeless dogs living in shelters find forever homes. Researchers found short-term fostering benefited shelter dogs in Arizona, Utah, Texas, Montana and Georgia. Stress hormone levels were reduced during one- and two-night sleepovers, and dogs also rested more during and immediately following a sleepover.
  • iconA bald gene findĀ­ing
    Hairlessness in dogs can be the result of deliberate breeding or, in certain breeds, a defect. A recent study describes a gene variant in the SGK3 gene, which causes hairlessness in Scottish deerhounds. The gene defect results in puppies born with thin fur that lose all of their hair in a few weeks. SGK3 is also a candidate for association with non-hormonal baldness in humans.

    As states around the country move to stiffen punishments for animal cruelty, researchers have found a correlation between the types of animal abuse committed and the perpetrator's relationship to an animal and its owner.
  • iconWolves lead, dogs follow -- and both cooperate with humans
    The statement is a bold one, especially as wolves have received a lot of negative attention in recent years. A recent study conducted by behavioral researchers, however, shows that dogs and wolves both work equally well with humans, albeit in different ways. The allegedly unequal brothers are thus much more similar than often assumed.
  • iconHungry moose more tolerant of wolves' presence
    Research in western Wyoming shows that close proximity of wolves does cause moose to move, but not enough to drive them from their preferred habitats -- especially late in the winter.
  • iconDebate on predator-prey relationships
    Experts have shed new light on the relationship between predators and their prey after studying how elk responded to the risk posed by grey wolves in an American national park.
  • iconDisrupting wolf movement may be more effective at protecting caribou

    As gray wolves return to Washington state, a new study finds that one species of deer is changing its behavior to spend more time away from roads, at higher elevations and in rockier landscapes.
  • iconLikelihood of tick bite to cause red meat allergy could be higher than previously thought
    The original hypothesis was that humans developed the red meat allergy after being exposed to the alpha-gal protein through a tick that had fed previously on a small mammal. But new data suggests ticks can induce this immune response without requiring the mammal blood meal, which likely means the risk of each bite potentially leading to the allergy is higher than doctors had anticipated.
  • iconGood dog? Bad dog? Their personalities can change
    When dog-parents spend extra time scratching their dogs' bellies, take their dogs out for long walks and games of fetch, or even when they feel constant frustration over their dogs' naughty chewing habits, they are gradually shaping their dogs' personalities.
  • iconFoxes were domesticated by humans in the Bronze Age
    In the northeast of the Iberian Peninsula, between the third and second millennium BC, a widespread funeral practice consisted in burying humans with animals. Scientists have discovered that both foxes and dogs were domesticated, as their diet was similar to that of their owners.
  • iconDog burial as common ritual in Neolithic populations of north-eastern Iberian Peninsula
    Coinciding with the Pit Grave culture (4200-3600 years before our era), coming from Southern Europe, the Neolithic communities of the north-eastern Iberian Peninsula started a ceremonial activity related to the sacrifice and burial of dogs. The high amount of cases that are recorded in Catalonia suggests it was a general practice and it proves the tight relationship between humans and these animals, which, apart from being buried next to them, were fed a similar diet to humans'.
  • iconCancer comparison across species highlights new drug targets
    Cancer genes in mucosal melanoma, a rare and poorly understood subtype of melanoma, have been compared in humans, dogs and horses for the first time.
