Yet another way dogs help the military: aeromedical patient evacuations
on August 22, 2019 at 6:19 pm
Animal-assisted therapy has many benefits in health care. Yet, its biological and psychosocial effects in the military are unknown, especially for injured, airlifted patients. Researchers teamed up with a non-profit animal organization that trains therapy dogs to see if an animal-assisted intervention could reduce stress in this setting. Results showed that levels of the stress biomarkers cortisol, alpha-amylase, and immunoglobulin A, significantly decreased after a 20-minute intervention with the dogs, regardless of post-traumatic stress symptom severity.
Hush, baby -- the dog is whimpering!
on August 21, 2019 at 4:08 pm
We are all familiar with the sounds of a cat or dog vying for human attention, and for pet-owners, these sounds are particularly evocative. Dog sounds are especially sad to both cat and dog owners, who actually rate a whimpering dog as sounding as sad as a crying baby.
Treating dogs with human breast cancer drug
on August 20, 2019 at 7:36 pm
Like many women who develop a particular type of breast cancer, the same gene -- HER2 -- also appears to be the cause of lung cancer in many dogs. Researchers found that neratinib -- a drug that has successfully been used to battle human breast cancer -- might also work for many of the nearly 40,000 dogs in the US that annually develop the most common type of canine lung cancer, known as CPAC.
Dog down: Effort helps emergency medical staff treat law enforcement K-9s
on August 20, 2019 at 2:14 pm
Law enforcement K-9s face the same dangers their human handlers confront. Recognizing a gap in care for law enforcement K-9s injured on the job, a team of veterinarians, emergency medical services experts and canine handlers has developed protocols for emergency medical service personnel who may be called upon to help treat and transport the injured dogs.
The growing trend of emotional support animals
on August 6, 2019 at 5:14 pm
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.
Intense look at La Brea Tar Pits explains why we have coyotes, not saber-toothed cats
on August 5, 2019 at 3:19 pm
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.
Fearing cougars more than wolves, Yellowstone elk manage threats from both predators
on August 2, 2019 at 4:27 pm
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.
Cancer without end? Discovery yields fresh insights
on August 1, 2019 at 10:09 pm
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.
The curious tale of the cancer 'parasite' that sailed the seas
on August 1, 2019 at 6:26 pm
A contagious canine cancer that conquered the world by spreading between dogs during mating likely arose around 6,000 years ago in Asia and spread around the globe through maritime activities, scientists say.
Gene transcripts from ancient wolf analyzed after 14,000 years in permafrost
on July 30, 2019 at 6:18 pm
RNA -- the short-lived transcripts of genes -- from the 'Tumat puppy', a wolf of the Pleistocene era has been isolated, and its sequence analyzed in a new study. The results establish the possibility of examining a range of RNA transcripts from ancient organisms, a possibility previously thought extremely unlikely because of RNA's short lifespan.
Genetic similarities of osteosarcoma between dogs and children
on July 19, 2019 at 5:55 pm
A bone cancer known as osteosarcoma is genetically similar in dogs and human children, according to the results of a new study. The findings could help break the logjam in the treatment of this deadly disease, which hasn't seen a significant medical breakthrough in nearly three decades.
Researchers track how cats' weights change over time
on July 16, 2019 at 9:41 pm
Researchers have accessed data on more than 19 million cats and have learned that most cats continue to put on weight as they age.
Inbreeding depression reduces litter sizes in golden retrievers
on July 9, 2019 at 6:12 pm
New research shows that inbreeding depression, the result of breeding closely-related individuals, reduces litter sizes in purebred golden retrievers.
It's dog eat dog on the canine social ladder
on July 3, 2019 at 1:13 am
Climbing the social ladder is a 'ruff' business for dogs, new research shows.
DNA from tooth in Florida man's foot solves 25-year-old shark bite mystery
on July 2, 2019 at 3:29 pm
In 2018, a Florida man found a piece of tooth embedded in his foot from a shark bite off Flagler Beach 24 years earlier. A DNA test of the tooth revealed the kind of shark that had nabbed his foot nearly a quarter century ago: a blacktip.
Learning from experience is all in the timing
on June 26, 2019 at 8:03 pm
Animals learn the hard way which sights, sounds, and smells are relevant to survival. New research in flies shows that the timing of these cues plays an important role in how mental associations arise, and elucidates brain pathways involved in this process.
Global data resource shows genetic diversity of chickens
on June 20, 2019 at 1:59 pm
A total of 174 chicken breeds are described in a publicly accessible database which scientists have built up in recent years. This database, the Synbreed Chicken Diversity Panel (SCDP), includes information about a large proportion of the available chicken species and their diversity. The researchers created a family tree of exceptional completeness and detail.
Joint hypermobility related to anxiety, also in animals
on June 19, 2019 at 3:12 pm
Researchers report the first evidence in a non-human species, the domestic dog, of a relation between joint hypermobility and excitability: dogs with more joint mobility and flexibility tend to have more anxiety problems.
The evolution of puppy dog eyes
on June 17, 2019 at 9:56 pm
Dogs have evolved new muscles around the eyes to better communicate with humans. New research comparing the anatomy and behavior of dogs and wolves suggests dogs' facial anatomy has changed over thousands of years specifically to allow them to better communicate with humans.
Managing the risk of aggressive dog behavior
on June 17, 2019 at 3:05 pm
Aggressive behavior in pet dogs is a serious problem for dog owners across the world, with bite injuries representing a serious risk to both people and other dogs. New research has found that clinical animal behaviorists should focus on helping dog owners to feel confident in the effectiveness of the behavior modification techniques that they recommend and, in their ability, to actually use them successfully.
