Owner behavior affects effort and accuracy in dogs' communications
on July 6, 2020 at 3:39 pm
Researchers have found that dogs adapt their communicative strategies to their environment and that owner behavior influences communicative effort and success. Experimental results found no evidence that dogs rely on communication history or follow the principle of least effort and suggest that owner behavior has a bigger impact on canine communication than previously thought.
The sixth sense of animals: An early warning system for earthquakes?
on July 6, 2020 at 2:18 pm
Continuously observing animals with motion sensors could improve earthquake prediction.
Grassroots dog vaccinations can help stop rabies, but not alone
on July 2, 2020 at 6:41 pm
While scientists are trying to find a vaccine for COVID-19, the rabies virus continues to kill 59,000 people every year. But unlike COVID, a vaccine has existed for more than a century. Vaccinating dogs can stop the spread to humans, but systemic challenges make that easier said that done. In a new study, scientists where grassroots campaigns to stop rabies work -- and where they need to be coupled with large-scale efforts.
How old is your dog in human years? New method better than 'multiply by 7'
on July 2, 2020 at 3:36 pm
How old is your tail-wagging bundle of joy in human years? According to the well-known ''rule of paw,'' one dog year is the equivalent of 7 years. Now scientists say it's wrong. Dogs are much older than we think, and researchers devised a more accurate formula to calculate a dog's age based on the chemical changes in the DNA as organisms grow old.
Sled dogs are closely related to 9,500-year-old 'ancient dog'
on June 25, 2020 at 6:48 pm
Sled dogs are much older and have adapted to Arctic conditions much earlier than previously thought. Researchers show that ancestors of modern sled dogs have worked and lived with humans for over 9,500 years.
Dangerous tick-borne bacterium extremely rare in New Jersey
on June 25, 2020 at 4:49 pm
There's some good news in New Jersey about a potentially deadly tick-borne bacterium. Researchers examined more than 3,000 ticks in the Garden State and found only one carrying Rickettsia rickettsii, the bacterium that causes Rocky Mountain spotted fever. But cases of tick-borne spotted fevers have increased east of the Mississippi River, and more research is needed to understand why.
'Cooperative' and 'independent' dog breeds may not react differently to unfair outcomes
on June 17, 2020 at 7:00 pm
Cooperative-worker dog breeds do not appear to respond more negatively to unfair outcomes than do independent-worker breeds, according to a new study. Although the sample size was small, the results do not support the hypothesis that inequity aversion and cooperation co-evolved.
Digitize your dog into a computer game
on June 16, 2020 at 5:57 pm
Researchers have developed motion capture technology that enables you to digitize your dog without a motion capture suit and using only one camera.
Monitoring environmental exposures in dogs could be early warning system for human health
on June 1, 2020 at 5:46 pm
Man's best friend may also be man's best bet for figuring out how environmental chemicals could impact our health.
Yes, your dog wants to rescue you
on May 29, 2020 at 7:07 pm
Imagine you're a dog. Your owner is trapped in a box and is crying out for help. Are you aware of his despair? If so, can you set him free? And what's more, do you really want to? That's what researchers wanted to know when they gave dogs the chance to rescue their owners.
Fearful Great Danes provide new insights to genetic causes of fear
on May 29, 2020 at 7:06 pm
Researchers have identified a new genomic region and anxiety-related candidate genes associated with fearfulness in dogs. Findings support their hypothesis that fearfulness and anxiety are hereditary traits in dogs, and there may be shared factors underlying anxiety in both humans and dogs.
CBD improves arthritis symptoms in dogs
on May 28, 2020 at 8:06 pm
This study shows that in dogs diagnosed with arthritis, CBD treatment significantly improved quality of life as documented by both owner and veterinarian assessments.
Reintroduction of wolves tied to return of tall willows in Yellowstone National Park
on May 28, 2020 at 8:05 pm
The reintroduction of wolves into Yellowstone National Park is tied to the recovery of tall willows in the park, according to a new study.
Why cats have more lives than dogs when it comes to snakebite
on May 18, 2020 at 10:49 pm
Cats are twice as likely to survive a venomous snakebite than dogs, and the reasons behind this strange phenomenon have just been revealed. The research team compared the effects of snake venoms on the blood clotting agents in dogs and cats, hoping to help save the lives of our furry friends.
Saving livestock by thinking like a predator
on May 14, 2020 at 8:42 pm
Humans have struggled to reduce the loss of livestock to carnivores for thousands of years, and yet, solutions remain elusive. According to a new study, solving this ancient puzzle requires going back to Ecology 101. Simply put, getting in the mind of predators -- considering how they hunt, how their prey behaves and the landscape -- will help wildlife managers discourage wild carnivores from preying on valuable livestock.
Dogs can detect traces of gasoline down to one billionth of a teaspoon
on May 12, 2020 at 7:19 pm
Trained dogs can detect fire accelerants such as gasoline in quantities as small as one billionth of a teaspoon, according to new research by chemists. The study provides the lowest estimate of the limit of sensitivity of dogs' noses and has implications for arson investigations.
The movie 'Jurassic Park' got it wrong: Raptors don't hunt in packs
on May 6, 2020 at 4:37 pm
A new analysis of raptor teeth shows that raptorial dinosaurs likely did not hunt in big, coordinated packs like dogs. Though widely accepted, evidence for this behavior is relatively weak. Recently, scientists have proposed a different model for behavior in raptors that is thought to be more like Komodo dragons, in which individuals may attack the same animal but cooperation is limited.
Stress in parents of children with autism: Pets may help
on April 27, 2020 at 2:04 pm
While current events have increased stress for all families, parents of children with autism report higher levels of stress on average than parents of typically developing kids. Feeling overwhelmed and overburdened by various responsibilities, some parents turn to pets as a source of comfort and support.
The origin of feces: coproID reliably predicts sources of ancient scat
on April 17, 2020 at 12:16 pm
The archaeological record is littered with feces, a potential goldmine for insights into ancient health and diet, parasite evolution, and the ecology and evolution of the microbiome. The main problem for researchers is determining whose feces is under examination.
Questionnaire survey identifies potential separation-related problems in cats
on April 15, 2020 at 7:29 pm
The first questionnaire survey to identify possible separation-related problems in cats found 13.5 percent of all sampled cats displayed potential issues during their owner's absence, according to a new study.
