  • iconTick bite protection: New CDC study adds to the promise of permethrin-treated clothing
    The case for permethrin-treated clothing to prevent tick bites keeps getting stronger. In new experiments, clothing treated with an insecticide known as permethrin had strong toxic effects on three primary species of ticks known to spread disease-causing pathogens in the United States. Exposure to permethrin interfered with the ticks' ability to move properly, making them sluggish and likely interfering with their ability to bite.
  • iconCause of E. coli beach closings? Gulls
    Researchers have recently published results identifying the major sources of E. coli breakouts on several beaches on Lake Michigan. They have also researched an effective method of reducing the breakouts and the resulting beach closings.

  • iconHunting dogs may benefit from antioxidant boost in diet
    Free radicals, those DNA-damaging single-oxygen atoms, are produced in spades during exercise. Dogs that exercise a lot, like hunting dogs, may need to consume more antioxidants than their less-active counterparts to protect against this damage. But what diet formulation best meets the needs of these furry athletes? A new study provides some answers in a real-world scenario.
  • iconCarnivores in captivity give birth at the same time of year as those in the wild
    Reproductive seasonality is a fixed characteristic of a species -- researchers have now found that carnivores in captivity give birth at the same time of year as their counterparts in the wild. In some species, the gestation period is shortened in order to provide ideal conditions for the offspring, while for others it is extended.
  • iconFrench bulldogs at risk of various health problems
    French bulldogs, predicted soon to become the most popular dog breed in the UK, are vulnerable to a number of health conditions, according to a new study.
  • iconDogs could be more similar to humans than we thought
    Dog and human gut microbiomes have more similar genes and responses to diet than we previously thought, according to a new study
  • iconHow tumors caused by STD quickly regress in dogs
    The canine transmissible venereal tumor is a contagious cancer that has spread by mating among dogs worldwide. One unique feature of this cancer is that, for unclear reasons, it regresses spontaneously or a few weeks after a single treatment of radiotherapy or chemotherapy. A study shines a light on this mystery, revealing a key role for the immune system in triggering fast cancer rejection in chemotherapy-treated dogs.

  • iconDogs with noise sensitivity should be routinely assessed for pain by vets
    Dogs which show fear or anxiety when faced with loud or sudden noises should be routinely assessed for pain by veterinarians, according to new research. Researchers believe that pain, which could be undiagnosed, could be exacerbated when a noise makes the dogs tense up or 'start', putting extra stress on muscles or joints which are already inflamed leading to and associated with a loud or startling noise.
  • iconFirst evidence of live-traded dogs for Maya ceremonies
    Earliest evidence that Mayas raised and traded dogs and other animals -- probably for ceremonies -- from Ceibal, Guatemala.
  • iconMice change their appearance as a result of frequent exposure to humans
    Many tame domesticated animals have a different appearance compared to their relatives in the wild, for example white patches in their fur or shorter snouts. Researchers have now for the first time shown that wild house mice develop the same visible changes -- without selection, as a result of exposure to humans alone.
  • iconSit, stay, heal: Study finds therapy dogs help stressed university students

  • iconHow cats and dogs are consuming and processing parabens
    Many households can claim at least one four-legged friend as part of the family. But pets that primarily stay indoors can have increased rates of diseases, such as diabetes, kidney diseases and hypothyroidism compared with those that stay exclusively outside. Some scientists propose that chemical substances in the home could contribute to these illnesses.
  • iconWho's a good boy? Why 'dog-speak' is important for bonding with your pet
    Scientists have shown that the way we speak to our canine friends is important in relationship-building between pet and owner, similar to the way that 'baby-talk' is to bonding between a baby and an adult.
  • iconBall or stuffed toy -- Do dogs 'know' what they're smelling?
    Dogs' excellent sense of smell is well-known, whether it is in the context of searching for people or for contraband substances. However, the question of how dogs understand what they perceive with their sense of smell has largely been unexplored. Scientists have now found evidence that dogs create a 'mental representation' of the target when they track a scent trail.

    Bites, kicks, and stings from farm animals, bees, wasps, hornets, and dogs continue to represent the most danger to humans, according to a new study.
  • iconVoice control: Why North Atlantic right whales change calls as they age
    Through extensive listening and analysis of whale calls -- which were recorded by a large collaboration of scientists over the past two decades -- researchers were able to pick up the slow gradual changes in sound production in the marine giants as they age. Looking at spectrograms of the calls, which provide visual representations of the sound, the research team could see the progression of vocal characteristics of the animals from calf throughout adulthood.
  • iconProof-of-concept study reveals feasibility of eliminating rabies in Africa
    Scientists have carried out a mass dog vaccination in Chad and determined its effect on human rabies exposure. The study employed a bio-mathematical method for estimating the transmission dynamics of rabies. The researchers conclude that with political will and the necessary funding, elimination of rabies is possible in Africa.
  • iconCracking the genetic code for complex traits in cattle
    The global 1000 Bull Genomes Consortium identified the genetic basis for accurately predicting the complex trait of height across cattle and dairy breeds by pooling large genomic datasets and phenotypes collected from 58,000 cattle. The team validated their findings using the DNA of a wild auroch, the ancient ancestor to all cattle and dairy breeds, and, in a world first, demonstrated the genes influencing height in cattle also influence the trait in humans and dogs.
  • iconBrain training for old dogs: Could touchscreen games become the Sudoku of man’s best friend?
    Spoiling old dogs in their twilight years by retiring them to the sofa and forgiving them their stubbornness or disobedience, doesn’t do our four-legged friends any good. Regular brain training and lifelong learning create positive emotions and can slow down mental deterioration in old age. Physical limitations, however, often do not allow the same sort of training as used in young dogs. In a new study, a team of researchers led by cognitive biologists propose computer interaction as a practical alternative. In the training lab, old dogs responded positively to cognitive training using educational touchscreen games.

    Researchers have found that female cats are much more likely to use their right paw than males.
  • iconHunting dogs as possible vectors for the infectious disease tularaemia
    Tularaemia is an infectious bacterial disease that is life-threatening for rodents, rabbits and hares, but which can also infect humans and dogs. While contact with contaminated blood or meat makes hunters a high-risk group, the frequency of infections among hunting dogs has not been much studied. Researchers have now confirmed a relevant prevalence of infections in Austrian hunting dogs following a serological study in which seven percent of the animals tested positive. This could lead to more intense debate as to whether the often asymptomatic animals represent an additional risk of infection for people.
  • iconCanine distemper confirmed in Far Eastern leopard, world's most endangered big cat
    The Far Eastern or Amur leopard (Panthera pardus orientalis) is already among the rarest of the world's big cats, but new research reveals that it faces yet another threat: infection with canine distemper virus (CDV).
  • iconAre amoebae safe harbors for plague?
    Amoebae, single-celled organisms common in soil, water and grade-school science classrooms, may play a key role in the survival and spread of deadly plague bacteria. New research shows that plague bacteria, Yersinia pestis, not only survive, but thrive and replicate once ingested by an amoeba. The discovery could help scientists understand why plague outbreaks can smolder, stay dormant for years, and re-emerge with a vengeance.
  • iconExperts raise concerns over raw meat diets for cats and dogs
    Experts are warning dog and cat owners to be aware of the risks associated with feeding their pets raw meat-based diets, instead of the more conventional dry or canned pet foods.

  • iconDogs may protect against childhood eczema and asthma
    Two new studies show there may be even more reason to love your dog as they may provide a protective effect against eczema and asthma.
  • iconDogs are more expressive when someone is looking
    Dogs produce more facial expressions when humans are looking at them, according to new research.
  • iconDomestication has not made dogs cooperate more with each other compared to wolves
    Following domestication, dogs should be more tolerant and cooperative with conspecifics and humans compared to wolves. But looking at both in more naturalistic living conditions, however, speaks for more cooperative behavior of wolves. Researchers now show that the wild ancestors are excelling their domesticated relatives in teamwork. In an experimental approach dogs but not wolves failed to cooperatively pull the two ends of a rope to obtain a piece of food.
  • iconUnraveling the genetics of disc disease in dogs
    Since the early 1900s, veterinarians have observed intervertebral disc disease -- a common cause of back pain, rear limb paralysis and inability to walk -- more frequently in dogs with short legs (dachshund, French bulldog, and Pekingese to name a few.) But they couldn't pinpoint why -- until now.Why short-legged dogs more likely to develop painful disease
  • iconHow rabies can induce frenzied behavior
    Scientists may finally understand how the rabies virus can drastically change its host's behavior to help spread the disease, which kills about 59,000 people annually. A new study shows how a small piece of the rabies virus can bind to and inhibit certain receptors in the brain that play a crucial role in regulating the behavior of mammals. This interferes with communication in the brain and induces frenzied behaviors that favor the transmission of the virus.
  • iconThe hormone that could be making your dog aggressive discovered
    Thousands of people are hospitalized every year for dog bites, and aggressive behavior is a major reason dogs end up in shelters. Biologists have studied the biology behind canine aggression, specifically the role of the hormones vasopressin and oxytocin.
