First validated canine behavioral genetics findings of nine fear, aggression traits in dogs

Anxiety disorders are the most common type of mental illness in the United States. And while much is understood about the biochemistry of anxiety, little is known about the genetic variation associated with it. A new study reports that genetic predisposition to aggression toward an owner or a familiar dog is distinct from that for fear and aggression directed at unfamiliar humans and dogs.

Frankfurter fraud: Finding out what's in your hot dog

Hot dogs are a common summer fare. But knowing for sure what you're getting inside a bun can be difficult. Now scientists have devised a method that could help prevent frankfurter fraud, which is especially important for those who can't eat certain types of meats. View the source article

Should the gray wolf keep its endangered species protection?

A decision by the US Fish and Wildlife Service to remove the gray wolf from protection under the US Endangered Species Act may be made as early as this fall. Research presents strong evidence that the scientific reason advanced by the service for delisting the gray wolf is incorrect. View the source article

Scientists test nanoparticle drug delivery in dogs with osteosarcoma

An engineer teamed up with a veterinarian to test a bone cancer drug delivery system in animals bigger than the standard animal model, the mouse. They chose dogs -- mammals closer in size and biology to humans -- with naturally occurring bone cancers, which also are a lot like human bone tumors. View the source article

Human 'super predator' more terrifying than bears, wolves and dogs

Bears, wolves and other large carnivores are frightening beasts but the fear they inspire in their prey pales in comparison to that caused by the human 'super predator.' A new study demonstrates that smaller carnivores, like European badgers, that may be prey to large carnivores, actually perceive humans as far more frightening. View the source article

Wolves seeks refuge from hunters during breeding periods

Wolves lower the risk of interacting with humans during the reproduction period -- when they are most vulnerable -- and adopt some similar behaviors in their areas, from Alaska to India and Afghanistan, according to a new study. View the source article

Spit personality

In the name of spit science, Douglas Granger and his colleagues have collected saliva samples from a restless polar bear, a college marching band and Navy medics dodging bullets in simulated combat. The mouthwatering liquid is a gold mine of information, says Granger, an "oral fluid" expert. A fraction of a drop of spit can be used to measure stress, decipher relationship dynamics, predict heart trouble and even help football players train more effectively. View the source article

Research highlights the legal issues of certifying emotional support animals

Service animals are recognized by the ADA as those whose training helps them serve a specific disability-related function. However, people not necessarily exhibiting a mental or physical disability are eluding the system by asking their mental health professionals to certify 'emotional support animals'. Researchers are exploring the effects these requests are having on the mental health profession and recommend that psychologists refrain from issuing certifications to avoid legal risks. View t

Is the Agile Wallaby man's new best friend?

Looking for a new pet? If so, consider the Agile Wallaby or the Asian Palm Civet. Responding to the growing trend in keeping exotic animals as pets a team of researchers has developed a methodology to assess the suitability of mammals to be kept domestically. The top five animals were: the Sika Deer, Agile Wallaby, Tamar Wallaby, Llama, and Asian Palm Civet. View the source article

Why architects should let the microbes in

Architectural design is often concerned with energy efficiency or aesthetics, not microbial exposure. But, in a new article environmental engineers make a case for assessing the benefits of having these unseen organisms in our homes. Maybe, they say, instead of pushing all of them out, we should let the right ones in. View the source article

King penguins keep an ear out for predators

Sleeping king penguins react differently to the sounds of predators than to non-predators and other sounds, when they are sleeping on the beach. Research has revealed that even asleep, these penguins can distinguish between dangerous and benign sounds. View the source article

Could goats become our new best friend?

Goats have the capacity to communicate with people like other domesticated animals, such as dogs and horses, according to scientists. The researchers hope the study will lead to a better understanding of how skilled livestock are in their aptitude to solve problems and interact with humans based on their cognitive abilities -- and to an improvement in animal welfare in general.

Filarial nematodes taking a fancy to Austria

In Austria, the parasitic roundworms Dirofilaria repens and Dirofilaria immitis are usually considered to be unpleasant souvenirs from travels abroad. A preliminary study has identified indigenous mosquitoes as carriers of Dirofilaria repens, suggesting for the first time that the parasite has become endemic in Eastern Austria. Dirofilaria immitis, commonly known as heartworm, also appears to be on the verge of becoming autochthonous. The slow pace at which the parasites are establishing themsel

Dogs were domesticated not once, but twice ... in different parts of the world

Scientists have compared genetic data with existing archaeological evidence and show that man's best friend may have emerged independently from two separate (possibly now extinct) wolf populations that lived on opposite sides of the Eurasian continent. This means that dogs may have been domesticated not once, as widely believed, but twice. View the source article
