Dogs promote page turning for young readers
on December 2, 2019 at 3:20 pm
Reading in the presence of a pooch may be the page-turning motivation young children need, suggests a researcher. A new study examines the behavior of 17 children from Grades 1 to 3 while reading with and without a dog.
Unique sled dogs helped the inuit thrive in the North American Arctic
on November 27, 2019 at 9:14 pm
The legacy of these Inuit dogs survives today in Arctic sled dogs, making them one of the last remaining descendant populations of indigenous, pre-European dog lineages in the Americas.
Dinosaur skull turns paleontology assumptions on their head
on November 25, 2019 at 10:34 pm
A team of researchers has unearthed a well-preserved Styracosaurus skull -- and its facial imperfections have implications for how paleontologists identify new species of dinosaurs. Nicknamed Hannah, the dinosaur was a Styracosaurus -- a horned dinosaur over five meters in length with a fan of long horns. Paleontologists have learned much from those horns -- because they aren't symmetrical.
Simple model explains why different four-legged animals adopt similar gaits
on November 21, 2019 at 7:14 pm
Most mammals walk at slow speeds and run or trot at intermediate speeds because these movement strategies are energetically optimal, according to a new study.
Dog and sheep bones help injured pigeons fly again
on November 20, 2019 at 5:11 pm
Sheep and dog bones can be whittled into orthopedic pins that stabilize pigeons' fractured wings, helping the fractures to heal properly without follow-up surgery. Researchers describe the treatment, which is cheaper and more efficient than using metal pins for pigeon rehabilitative surgeries.
Watch out for 'feather duvet lung' caution doctors
on November 19, 2019 at 12:08 am
Watch out for 'feather duvet lung' doctors have warned after treating a middle aged man with severe lung inflammation that developed soon after he bought feather-filled bedding.
Humans' ability to read dogs' facial expressions is learned, not innate
on November 11, 2019 at 3:50 pm
Researchers assessed how experience with dogs affects humans' ability to recognize dog emotions. Participants who grew up in a cultural context with a dog-friendly attitude were more proficient at recognizing dog emotions. This suggests that the ability to recognize dogs' expressions is learned through age and experience and is not an evolutionary adaptation.
AI could help diagnose dogs suffering from chronic pain and Chiari-like malformation
on November 7, 2019 at 4:29 pm
A new artificial intelligence (AI) technique could eventually help veterinarians quickly identify Cavalier King Charles Spaniel (CKCS) dogs with a chronic disease that causes crippling pain. The same technique identified unique biomarkers which inspired further research into the facial changes in dogs affected by Chiari-like malformation (CM).
Liver-chip identifies drug toxicities in human, rat, and dog models
on November 6, 2019 at 7:48 pm
Liver toxicity is a big problem in the drug, food, and consumer products industries, especially because results in animal models fail to predict how chemicals will affect humans. A new Liver-Chip successfully predicts how different drugs impact rat, dog, and human models, and could help get the most effective drugs to patients faster.
New findings on gut microbiome's interactions with GI diseases
on November 6, 2019 at 5:41 pm
A study offers new insight on how the gut bacteria of dogs interact with a healthy vs. unhealthy GI tract, which could contribute to the development of new therapies for GI diseases in both dogs and humans.
Your dog might be hiding its true colors
on November 5, 2019 at 7:09 pm
New research shows that some breeds of dogs have hidden coat colors -- and in some cases, other traits -- that have been lurking all along.
Estrogen's opposing effects on mammary tumors in dogs
on November 1, 2019 at 10:34 pm
Estrogen's role in canine mammary cancer is more complex than previously understood, according to new research. The nuanced findings may help explain why dogs spayed at a young age are more likely to develop more aggressive cancers, the team says.
Detection dogs and DNA on the trail of endangered lizards
on October 30, 2019 at 12:28 pm
Detection dogs trained to sniff out the scat of an endangered lizard in California's San Joaquin Valley, combined with genetic species identification, could represent a new noninvasive sampling technique for lizard conservation worldwide.
Genetic risk factor for laryngeal paralysis in miniature bull terriers identified
on October 24, 2019 at 6:12 pm
Laryngeal paralysis is a serious and sometimes deadly disease in some dog breeds that prevents proper opening of the larynx for breathing. Specialists in canine head and neck surgery and geneticists have identify a mutation responsible for laryngeal paralysis in Miniature Bull Terriers, enabling the development of a genetic test for the disease.
Respiratory diseases linked with high blood pressure in lungs
on October 16, 2019 at 7:36 pm
Pulmonary hypertension is a type of high blood pressure that affects the lungs of both animals and people. When tiny vessels in the lungs become narrowed or blocked, it becomes harder for blood to flow through and can cause the heart to weaken or fail.
Genes play a role in dog breed differences in behavior
on October 8, 2019 at 8:58 pm
Border collies are highly trainable, greyhounds love to chase, and German shepherds make good guard dogs. While the environment plays a role, traits like these are highly heritable, according to a study of 101 dog breeds. The work identifies 131 genetic variants associated with breed differences in behavior.
Dog ownership associated with longer life, especially among heart attack and stroke survivors
on October 8, 2019 at 12:31 pm
Dog ownership was associated with a 33% lower risk of early death for heart attack survivors living alone and 27% reduced risk of early death for stroke survivors living alone, compared to people who did not own a dog. Dog ownership was associated with a 24% reduced risk of all-cause mortality and a 31% lower risk of death by heart attack or stroke compared to non-owners.
Dog owners often inaccurately measure out kibble
on October 7, 2019 at 4:32 pm
New research finds dog owners are often inaccurate when measuring out kibble using a scoop, putting the dogs at risk of under-nourishment or weight gain.
Identifying a gene for canine night blindness
on October 3, 2019 at 9:37 pm
Researchers have identified the gene mutation responsible for a form of night blindness in dogs. Strategies to treat this condition, which affects a layer of neurons just below the primary photoreceptor cells, could also inform treatment of other diseases that rely on targeting this cell type.
Lop-eared rabbits more likely to have tooth/ear problems than erect eared cousins
on October 1, 2019 at 10:49 pm
Lop (floppy) eared rabbits are more likely than erect ('up') eared breeds to have potentially painful ear and dental problems that may ultimately affect their ability to hear and eat properly, finds a small observational study.
