    Scientists have identified genetic changes that are linked to dogs' human-directed social behaviors and suggest there is a common underlying genetic basis for hyper-social behavior in both dogs and humans.
  • iconOrigin of modern dog has a single geographic origin, study reveals
    By analyzing the DNA of two prehistoric dogs from Germany, an international research team has determined that their genomes were the probable ancestors of modern European dogs. The finding suggests a single domestication event of modern dogs from a population of gray wolves that occurred between 20,000 and 40,000 years ago.
  • iconFirst genomic biomarkers in extracellular vesicles in veterinary patients
    Important biomarkers have been found in extracellular vesicles in dogs with myxomatous mitral valve disease and congestive heart failure. This is the first biomarker discovery based on extracellular vesicles in a veterinary disease. These findings could provide important insight into the molecular basis, diagnosis and therapies for myxomatous mitral valve disease in dogs, as well as mitral valve prolapse, a similar disease in humans.
  • iconFOXI3 gene is involved in dental cusp formation
    Hairless dog breeds differ from other dogs not only by lacking a coat, but also in the number and nature of their teeth. Scientists studied the skulls and teeth of pedigreed hairless dogs from the collection of the Phyletisches Museum of the University of Jena. Thus, they furthered our understanding of the involvement of the FOXI3 gene in the development of teeth - not only in hairless dogs, but potentially also in other mammals including humans.

    Researchers have surveyed the environmentally protected area in Campinas, Southeastern Brazil, which has undergone several changes by human action, especially the implementation of condominiums, and revealed that more than one percent of dogs, as well as some opossums and insect species in the area carry the parasite responsible for the most dangerous form of leishmaniasis.
  • iconReal-time vapor analysis could improve training of explosive-detecting dogs
    With a sense of smell much greater than humans, dogs are considered the gold standard for explosive detection in many situations. But that doesn't mean there isn't room for improvement. In a new study, scientists report on a new, more rigorous approach to training dogs and their handlers based on real-time analysis of what canines actually smell when they are exposed to explosive materials.
  • iconDon't lose sleep over sharing your bed with your pet or kids
    About half of all pet owners share their beds or bedrooms with their pets. Studies about co-sleeping are limited to the bedtime arrangements of adults, or parents and their children. Researchers say that society regards both human-animal and adult-child co-sleeping with apprehension. These concerns should be set aside because both practices have their benefits, says the lead author of a new study.
  • iconDogs to sniff out chemicals that identify human remains
    New research to help improve accuracy of criminal investigations involves a partnership between humans and their canine coworkers.
  • iconPiglets prefer new toys, behavior study shows
    We can't help but be tempted by new things. We see it in a child's eyes when she opens a new toy, and feel it every time a new version of the iPhone is released. It turns out our preference for shiny, new things is pretty universal throughout the animal kingdom. Yes, even piglets prefer new toys.
  • iconMemory for stimulus sequences distinguishes humans from other animals
    Humans possess many cognitive abilities not seen in other animals, such as a full-blown language capacity as well as reasoning and planning abilities. Despite these differences, however, it has been difficult to identify specific mental capacities that distinguish humans from other animals. Researchers have now discovered that humans have a much better memory to recognize and remember sequential information.

  • iconSensitivity to inequity is in wolves' and dogs' blood
    Not only dogs but also wolves react to inequity -- similar to humans or primates, suggests new research. Wolves and dogs refused to cooperate in an experiment when only the partner got a treat or they themselves received a lower quality reward. The sensitivity to inequity is not likely to be an effect of domestication, as assumed so far. It is rather a behavior inherited from a common ancestor.
  • iconNatural capital: Holistic management makes ecosystems healthier, people wealthier
    A new study puts a price on ecosystems by recognizing the value of a 'natural capital' asset -- in this case, fish in the Baltic Sea -- and connecting it with holistic ecosystem management to calculate asset values for the interacting parts of an ecosystem.
  • iconDogs help in breast carcinoma research
    Cancer of the mammary glands in dogs is very similar to human breast carcinoma. For this reason, treatment methods from human medicine are often used for dogs. Conversely, scientific knowledge gained from canine mammary tumors may also be important to human medicine. Researchers were able to show how similar these tumors are in both dogs and humans.
  • iconCensus shows which mammals survive in forests surrounded by sugarcane plantations
    A census of medium and large mammals found in 22 forest remnants surrounded by sugarcane plantations in the state. They found approximately 90% of all the species of mammals expected for São Paulo State but in smaller forest fragments, the researchers recorded only 20 percent - 50 percent of the species expected to occur across the region. This means that up to 80 percent were locally extinct in some cases.
  • iconGene finding to eradicate severe blistering disorder of the skin found in dogs
    Researchers have identified a novel gene defect that causes a hereditary blistering disorder of the skin, epidermolysis bullosa, in dogs. Epidermolysis bullosa, found in the Central Asian Shepherd dog breed, occurs also in humans due to an identical gene found in both canines and humans.
  • iconOutnumbered and on others' turf, misfits sometimes thrive
    Evolutionary biologists have long assumed that when an individual of a species wanders into a different environment than it is adapted to, it will be at a competitive disadvantage compared to natives of the same species which are adapted to that environment. Studying fish in Canada, scientists found the opposite.

This gene confers resistance to all beta-lactam antibiotics including the last generation of cephalosporins used against methicillin-resistant Staphylococcus aureus. A transfer to S. aureus which is likely according to the researchers would jeopardize the use of reserve antibiotics to treat human infections caused by multidrug-resistant bacteria in hospitals.
  • iconThe evolution of dog breeds now mapped
    When people migrate, Canis familiaris travels with them. Piecing together the details of those migrations has proved difficult because the clues are scattered across the genomes of hundreds of dog breeds. However, in a new report, researchers have used gene sequences from 161 modern breeds to assemble an evolutionary tree of dogs. The map of dog breeds, which is the largest to date, unearths new evidence that dogs traveled with humans across the Bering land bridge.

    Dynamics between familiar dogs may influence their likelihood of learning from each other, new research shows. How dogs interact with others plays a big role in how they respond under conditions that require quick thinking.
  • iconTarantula wolf spiders use their lateral eyes to calculate distance
    A necessary part of any animal's sense of direction is a positioning system, allowing it to have an idea of the relation between where it is and where it wants to go; this is known as odometry. A new study shows that tarantula wolf spiders (Lycosa tarantula) use their posterior lateral eyes and anterior lateral eyes (they have a total of four pairs of eyes) to establish the distance they have traveled.

  • iconSandy the dingo wins world's most interesting genome competition
    A wild-born, pure Australian desert dingo called Sandy Maliki has taken out first place in the World's Most Interesting Genome competition. The UNSW-led proposal to have Sandy's DNA decoded beat four other finalists for the Pacific Biosciences SMRT Grant, which provides cutting-edge sequencing of the complete genome of a particularly fascinating plant or animal.
  • iconYou spy with your little eye, dogs can adopt the perspective of humans
    Humans are able to interpret the behavior of others by attributing mental states to them (and to themselves). By adopting the perspectives of other persons, they can assume their emotions, needs and intentions and react accordingly. In the animal kingdom, the ability to attribute mental states (Theory of Mind) is a highly contentious issue. Cognitive biologists could demonstrate with a new test procedure that dogs are not only able to identify whether a human has an eye on a food source and, therefore, knows where the food has been hidden. They can also apply this knowledge in order to correctly interpret cues by humans and find food they cannot see themselves.

    A team of researchers has demonstrated the efficacy of administration of a therapeutic vector by a single intravenous injection and identified the dose that restores long-term muscular strength in a large animal model of the disease.
  • iconRaccoon dog represents a more acute risk than raccoon as vector for transmission of local parasites
    The raccoon and the raccoon dog are two non-indigenous animal species that have become established in Europe in the past decades. Their increasing abundance has not only made them the most common carnivore species in some countries, but has also made them of interest to parasitologists as potential hosts for diseases. A team of researchers has now analyzed samples from both species in Austria. The raccoon dog, which is more closely related to the fox, was shown to serve as an additional host for local parasites. Like the fox, it represents a risk as a host of zoonotic parasites, such as the fox tapeworm or trichina worms, that are also of relevance for humans. The raccoons sampled, as they mainly originated from fur farms, were still largely pathogen-free.
  • iconBig-game jitters: Coyotes no match for wolves' hunting prowess
    As wolf populations plummeted, the eastern coyote assumed the role of apex predator in forests along the Atlantic Coast. New research, however, shows that the eastern coyote is no match for the wolf. While the eastern coyote can bring down moose and other large prey, it prefers to attack smaller animals and to scavenge.
  • iconMinitablets help medicate picky cats
    Of all pets, cats are often considered the most difficult ones to medicate. Very small minitablets with flavors or flavor coatings can help cat owners commit to the treatment and make cats more compliant to it, while making it easier to regulate dosage and administer medication flexibly.
  • iconSecuring the future of cattle production in Africa

  • iconNovel socio-ecological approach helps identifying suitable wolf habitats in human-dominated landscapes
    About one third of the Swiss landscape offers suitable wolf habitat. Nonetheless, there is only a small fraction thereof where the wolf is tolerated by local communities. Those regions – characterized by both favorable environmental conditions and a positive attitude towards the wolf – are identified as candidate regions for the successful short to medium-term wolf expansion, according to a study.
  • iconCan’t we all just get along – like India’s cats and dogs?
    Three carnivores -- tigers, leopards, and dholes (Asian wild dog) -- seemingly in direct competition with one other, are living side by side with surprisingly little conflict, new study in India shows.
  • iconGene therapy treats muscle-wasting disease in dogs
    Dogs with an inherited muscle-wasting disorder that was treated with a single infusion of corrective gene therapy were indistinguishable from normal animals one year later. Puppies with this naturally occurring, fatal genetic mutation and babies with the same defective gene have several similar symptoms. Scientists found a way to safely replace the disease-causing MTM gene with a healthy gene throughout the entire musculature of affected dogs, and are now trying to determine the most effective dosage and timing.
  • iconEbolaviruses need very few mutations to cause disease in new host species
    Ebola is one of the world's most virulent diseases, though rodent species such as guinea pigs, rats and mice are not normally susceptible to it. However, through repeated infection of a host animal, Ebola virus strains can be generated that replicate and cause disease within new host rodent species.
