When people hear another person talking to them, they respond not only to what is being said -- those consonants and vowels strung together into words and sentences -- but also to other features of that speech -- the emotional tone and the speaker's gender, for instance. Now, a report provides some of the first evidence of how dogs also differentiate and process those various components of human s
If you've ever watched a dog drink water, you know that it can be a sloshy, spilly, splashy affair -- in other words, adorable. Behind all of the happy, wet messes, however, lies the mechanical logic of carnivorous compensation -- dogs splash when they drink because they have the cheeks of a predatory quadruped. By studying the drinking habits of various dog breeds and sizes, researchers have rece
Bacteria compete for resources in the environment by injecting deadly toxins into their rivals. Researcher have now discovered that many animals steal toxins from bacteria to fight unwanted microbes growing on them. Genes for these toxins have jumped from bacterial to animals. These genes are now permanently incorporated into the genomes of these animals. Deer ticks, which can carry Lyme disease,
Canines trained on pseudo-explosives could not reliably identify the genuine article (and vice versa). When it comes to teaching dogs how to sniff out explosives, there’s nothing quite like the real thing to make sure they’re trained right.
Biogeologists have shown how Gravettian people shared their food 30,000 years ago. Around 30,000 years ago Predmosti was inhabited by people of the pan-European Gravettian culture, who used the bones of more than 1000 mammoths to build their settlement and to ivory sculptures. Did prehistoric people collect this precious raw material from carcasses -- easy to spot on the big cold steppe -- or were
With both wolf proposals shot down by Michigan voters on election day, the debate over managing and hunting wolves is far from over. A new study identifies the themes shaping the issue and offers some potential solutions as the debate moves forward.
Cats and humans have shared the same households for at least 9,000 years, but we still know very little about how our feline friends became domesticated. An analysis of the cat genome reveals some surprising clues.
People find the smell of blood unpleasant, but for predatory animals it means food. When behavioral researchers wanted to find out which substances of blood trigger behavioral reactions, they got some unexpected results.
The smallest member of the Mary Rose crew -- the ship’s dog -- was a he, and not a she as was previously believed, experts say. The skeleton of the dog lacked a baculum, or penis bone, and so was thought for many years to be that of a female dog. The dog, named "Hatch" by researchers, was discovered in 1981 during the underwater excavation of the ship, which sank defending Portsmouth from a French
Arthritis pain in dogs can be relieved, with no side effects, by a new product based on medicinal plants and dietary supplements. Two formulas were developed. The first formula, composed of curcumin, devil's claw, black current, Indian frankincense (Salai), willow bark, pineapple bromelaine and camomile, was developed to treat arthritis-induced inflammation. The second included the same ingredient
Along with the pressures of habitat loss, poaching and depletion of prey species, a new threat to tiger populations in the wild has surfaced in the form of disease, specifically, canine distemper virus (CDV). According to a new study, CDV has the potential to be a significant driver in pushing the animals toward extinction.
After a few generations of breeding and natural selection, hybrid fish are genetically as robust as their purely wild forefathers, new research shows. The team transplanted combinations of wild, domesticated and hybridized populations of Algonquin Park vbrook trout to new environments. The researchers then compared survival rates and physical characteristics to determine whether hybridization affe
A research team is working to better understand cancer in dogs, and the work also could advance knowledge of human cancer. Their investigation began with only a tiny blood platelet, but quickly they discovered opportunities for growth and expanding the breadth of the research. "As veterinarians, we are focused on treating cancer in dogs and we get the bonus of also helping advance treatment of hum
A suite of technologies that can be used to enhance communication between dogs and humans has been developed by researchers who say that it has applications in everything from search and rescue to service dogs to training our pets.
Animal-assisted therapy can reduce symptoms of anxiety and loneliness among college students, according to researchers who provided animal-assisted therapy to 55 students in a group setting at a small arts college. They found a 60 percent decrease in self-reported anxiety and loneliness symptoms following animal-assisted therapy, in which a registered therapy dog was under the supervision of a lic
Scientists studying birth defects in humans and purebred dogs have identified an association between cleft lip and cleft palate -- conditions that occur when the lip and mouth fail to form properly during pregnancy -- and a mutation in the ADAMTS20 gene.
Global declines in carnivore populations could embolden plant eaters to increasingly dine on succulent vegetation, driving losses in plant and tree biodiversity, according to new research published in Science.
A fly's sense of smell could be used in new technology to detect drugs and bombs, new research has found. Brain scientists were surprised to find that the ‘nose’ of fruit flies can identify odors from illicit drugs and explosive substances almost as accurately as wine odor, which the insects are naturally attracted to because it smells like their favorite food, fermenting fruit.
How closely does the relationship between people and their non-human companions mirror the parent-child relationship? Researchers makes a contribution to answering this complex question by investigating differences in how important brain structures are activated when women view images of their children and of their own dogs.
Zoonosis -- transmission of infections from other vertebrates to humans -- causes regular and sometimes serious disease outbreaks. Bats are a well-known vertebrate reservoir of viruses like rabies and Ebola. Recent discovery of sequences in bats that are resemble influenza virus genes raised the question of whether bat flu viruses exist and could pose a threat to humans.
The bond between humans and dogs is strong and ancient. Dogs and people share many aspects of life. The relationship between the two species has been studied by psychologists, anthropologists, ethnologists and also by genetic and molecular biologists. In this sense, dogs are a great model for understanding the causes of human diseases, especially cancer. Unlike other mammals used in research, dogs
Americans love their dogs, but they don't always love to pick up after them. And that's a problem. Dog feces left on the ground wash into waterways, sometimes carrying bacteria -- including antibiotic-resistant strains -- that can make people sick. Now scientists have developed a new genetic test to figure out how much dogs are contributing to this health concern.
Pet food mislabeling: the issue is a significant one when it comes to commercial pet foods marketed for dogs and cats. New research set out to identify meat species present as well as any instances of mislabeling. Of the 52 products tested, 31 were labeled correctly, 20 were potentially mislabeled, and one contained a non-specific meat ingredient that could not be verified.
Truffles, along with caviar, are among the most expensive foods in the world. Because they grow underground, people use trained dogs or pigs to find them. But the distinctive smell of truffles is not only of interest to gourmets. A group of scientists has discovered that the smell of white truffles is largely produced by soil bacteria which are trapped inside truffle fruiting bodies.
Ridding the world of rabies in humans is cost-effective and achievable through mass dog vaccination programs, an international team of researchers says. A rabies vaccine has long existed. Even so, the disease kills an estimated 69,000 people worldwide -- that's 189 each day. Forty percent of them are children, mostly in Africa and Asia. The disease is spread primarily through the saliva of infecte
In a first-of-its kind study that combined molecular and environmental data, researchers performed a search for genes under environmental selection from domesticated sheep breeds. They identified 17 genes that are involved in energy metabolism, endocrine and autoimmune regulation.
Nearly one out of four dogs will develop cancer in their lifetime and 20 per cent of those will be lymphoma cases. Now, a new user-friendly electronic system for diagnosing lymphoma in dogs in the early stages, and for remission monitoring, has been developed by scientists.
Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that most would have an optimistic outlook on life. In fact some dogs are distinctly more pessimistic than others, new research shows.
Dogs look at a person interacting with a new object longer than a person interacting with a familiar object moved to a different location, suggesting perception of goal-directed behavior, according to a new study.
A team of Spanish researchers have obtained the first partial genome sequence of an ancient pig. Extracted from a sixteenth century pig found at the site of the Montsoriu Castle in Girona, the data obtained indicates that this ancient pig is closely related to today's Iberian pig. Researchers also discard the hypothesis that Asian pigs were crossed with modern Iberian pigs.
