  • Prototype of robot dog nose
    on November 19, 2018 at 8:59 pm

    Every day, thousands of trained K9 dogs sniff out narcotics, explosives and missing people. These dogs are invaluable for security, but they're also expensive. Researchers have made the beginning steps toward an artificial 'robot nose' device that officers could use instead of dogs. The heart of the system would be living odor receptors grown from mouse genes that respond to target odors, including the smells of cocaine and explosives. […]

  • Geneticist solves long-standing finch beak mystery
    on November 19, 2018 at 11:41 am

    Biologist have compared the genes of large-beaked Cameroonian finches to those of their smaller-beaked counterparts, found the answer to a 20-year old mystery: 300,000 base pairs, apparently inherited as a unit, always varied between them, and right in the middle of that genetic sequence was the well-known growth factor, IGF-1. […]

  • No link between 'hypoallergenic' dogs and lower risk of childhood asthma
    on November 15, 2018 at 4:53 pm

    Growing up with dogs is linked to a lower risk of asthma, especially if the dogs are female, a new study shows. However, the researchers found no relation between 'allergy friendly' breeds and a lower risk of asthma. […]

  • Treatment for canine leishmaniasis exists in Brazilian vaccine
    on November 14, 2018 at 9:43 pm

    A vaccine used to prevent dogs from contracting the deadly, parasitic disease canine leishmaniasis also can be used to treat currently infected dogs, providing a new avenue of treatment for millions of infected dogs globally. […]

  • Dogs detect malaria by sniffing socks worn by African children
    on October 29, 2018 at 2:28 pm

    As the global battle against malaria stalls, scientists may be adding a novel tool to the fight: sniffer dogs. In recent tests trained sniffer dogs successfully diagnosed malaria infections simply by sniffing samples from socks worn briefly by children from a malaria endemic area of West Africa, according to a new study. […]

  • Smell and behavior: The scents of taking action
    on October 29, 2018 at 12:40 pm

    Scientists have discovered a neural pathway that links olfaction to locomotion. […]

  • What makes a good working dog? Canine 'aptitude test' might offer clues
    on October 25, 2018 at 7:10 pm

    A canine cognition test could help organizations that train working dogs identify the dogs that are most likely to succeed, according to new research. If organizations could better predict which dogs will succeed in working roles, it could save thousands of dollars in training costs and ensure people in need get dogs faster. […]

  • Glyphosate found in cat and dog food
    on October 24, 2018 at 8:36 pm

    A new study finds that glyphosate, the active herbicidal ingredient in widely used weed killers like Roundup, was present at low levels in a variety of dog and cat foods the researchers purchased at stores. Before you go switching Fido or Fluffy's favorite brand, however, be aware that the amounts of the herbicide found correspond to levels currently considered safe for humans. […]

  • Yes, your pet can tell time
    on October 23, 2018 at 5:05 pm

    A new study has found some of the clearest evidence yet that animals can judge time. By examining the brain's medial entorhinal cortex, the researchers discovered a previously unknown set of neurons that turn on like a clock when an animal is waiting. […]

  • A dog's color could impact longevity, increase health issues
    on October 22, 2018 at 12:58 pm

    New research has revealed the life expectancy of chocolate Labradors is significantly lower than their black and yellow counterparts. […]

  • Letting nature take its course: Wolves in Yellowstone National Park
    on October 16, 2018 at 7:07 pm

    Since the reintroduction of wolves to Yellowstone National Park in 1995, the park's ecosystem has become a deeply complex and heterogeneous system, aided by a strategy of minimal human intervention. The new study is a synthesis of 40 years of research on large mammals in Yellowstone National Park. […]

  • Scientists chase mystery of how dogs process words
    on October 15, 2018 at 4:09 pm

    Experimental results suggest that dogs have at least a rudimentary neural representation of meaning for words they have been taught, differentiating words they have heard before from those they have not. […]

  • Puppy-killing disease rampant in Australia
    on October 10, 2018 at 2:57 pm

    A study has found that canine parvovirus (CPV), a highly contagious and deadly disease that tragically kills puppies, is more prevalent than previously thought with 20,000 cases found in Australia each year, and nearly half of these cases result in death. […]

  • Why huskies have blue eyes
    on October 4, 2018 at 6:39 pm

    DNA testing of more than 6,000 dogs has revealed that a duplication on canine chromosome 18 is strongly associated with blue eyes in Siberian Huskies. […]

  • Have asthma and a pet? Re-homing your cat or dog may not be necessary
    on October 4, 2018 at 3:26 pm

    A study analyzed environmental exposures, like pet and secondhand smoke, to determine if they have a role in asthma control among children whose asthma is managed per NAEPP (EPR-3) guidelines. Researchers found that once asthma guidelines are followed, environmental exposures to pets or secondhand smoke were not significant factors in overall asthma improvement over time. […]

  • Dog intelligence 'not exceptional'
    on October 1, 2018 at 12:21 pm

    People who think dogs are exceptionally intelligent are barking up the wrong tree, new research shows. […]

  • Silver fox study reveals genetic clues to social behavior
    on September 27, 2018 at 2:56 pm

    After more than 50 generations of selective breeding, a new study compares gene expression of tame and aggressive silver foxes in two areas of the brain, shedding light on genes responsible for social behavior. […]

  • Sniffing out error in detection dog data
    on September 14, 2018 at 2:04 pm

    New research finds three alternative answers beyond errors in handler or dog training that can explain why dogs trained to identify scat for conservation purposes sometimes collect non-target scats. […]

  • Virus may help combat fire ants, but caution is needed
    on September 11, 2018 at 3:02 pm

    A specific virus changes dietary behavior of fire ants, leading researchers to rethink control methods for the invasive species. […]

  • How wolf predation shapes elk antler evolution
    on September 5, 2018 at 3:32 pm

    A new study chronicles an evolutionary tie between wolves and when bull elk shed their antlers. […]
