Learning from experience is all in the timing

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. View the source article

Global data resource shows genetic diversity of chickens

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. View the source article

Joint hypermobility related to anxiety, also in animals

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. View the source article

The evolution of puppy dog eyes

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. View the source article

Managing the risk of aggressive dog behavior

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.

Better prognosticating for dogs with mammary tumors

For dogs with mammary tumors, deciding a course of treatment can depend on a variety of factors, some of which may seem to contradict one another. With a new, practical system developed by veterinarians, determining a prognosis and making treatment decisions should be an easier task. View the source article

Dogs mirror owner's stress

The levels of stress in dogs and their owners follow each other, according to a new study. The scientists believe that dogs mirror their owner's stress level, rather than vice versa. View the source article

Wild boars, hunting dogs and hunters carry tick-borne bacteria

Rickettsia bacteria cause a number of human and animal infections, including Rocky Mountain spotted fever. Now, researchers have for the first time surveyed the prevalence of Rickettsia antibodies and Rickettsia-carrying ticks in wild boars, hunting dogs and hunters in Brazil. View the source article

Study identifies dog breeds, physical traits that pose highest risk of biting children

Nearly five million people are bitten by dogs each year in the United States, and children are at a much higher risk than adults. Dog bites can cause significant psychological and physical damage, and bites to the face often require reconstructive surgery to repair injuries ranging from nerve damage to tissue loss. While certain breeds are known to bite more frequently or cause more severe injuries, a new study finds the breed was unknown in about 60 percent of dog bite cases. View the source

Owning a dog is influenced by our genetic make-up

Scientists have studied the heritability of dog ownership using information from 35,035 twin pairs from the Swedish Twin Registry. The new study suggests that genetic variation explains more than half of the variation in dog ownership, implying that the choice of getting a dog is heavily influenced by an individual's genetic make-up.

Make room on the couch: Worms suffer from PTSD, too

Researchers have discovered that even a very basic animal life form like the C. elegans worm has the ability to learn from past experiences. Further, the research team has pinpointed the exact neurons that store these memories and the physiological changes the worms undergo when they retrieve memories to cope with future hardships.
