Cancer comparison across species highlights new drug targets

Cancer genes in mucosal melanoma, a rare and poorly understood subtype of melanoma, have been compared in humans, dogs and horses for the first time. Researchers sequenced the genomes of the same cancer across different species to pinpoint key cancer genes. The results give insights into how cancer evolves across the tree of life and could guide the development of new therapies. View the source article

Overlapping genomic regions underlie canine fearfulness and human mental disorders

Researchers have identified two novel anxiety-related genomic regions in German Shepherd dogs. The region associated with fearfulness corresponds with the locus of human chromosome 18, which is associated with various psychiatric disorders, while the region associated with noise sensitivity includes several genes related to human and canine behavior and mental disorders.

11,500-year-old animal bones in Jordan suggest early dogs helped humans hunt

11,500 years ago in what is now northeast Jordan, people began to live alongside dogs and may also have used them for hunting, a new study shows. The archaeologists suggest that the introduction of dogs as hunting aids may explain the dramatic increase of hares and other small prey in the archaeological remains at the site.

Bulldogs' screw tails linked to human genetic disease

With their small size, stubby faces and wide-set eyes, bulldogs, French bulldogs and Boston terriers are among the most popular of domestic dog breeds. Now researchers have found the genetic basis for these dogs' appearance, and linked it to a rare inherited syndrome in humans. View the source article

Snowed in: Wolves stay put when it's snowing

Wolves travel shorter distances and move slower during snowfall events, according to new research. The effects were most pronounced at night, when wolves hunt, and behavior returned to normal within a day. View the source article

Students around the globe collect quality, eye-opening research data on mammals

Researchers are running a large-scale camera-trap study called eMammal, recently enlisted the help of K-12 students from 28 schools and four countries -- the United States, India, Mexico and Kenya. What the researchers, and the kids, discovered was surprising. View the source article

A future for red wolves may be found on Galveston Island, Texas

Red wolves, once nearly extinct, again teeter on the abyss. New research finds red wolf ancestry in Texas -- providing opportunities for additional conservation action and difficult policy challenges. Researchers have identified red wolf ''ghost alleles'' in canid population on Galveston Island. View the source article

New method to treat life-threatening heart arrhythmias in dogs

Researchers have developed a new treatment for dogs with a rare, but life-threatening, arrhythmia caused by atrioventricular accessory pathways (APs). The minimally invasive technique, which uses radiofrequencies, is modified from a human cardiology procedure and has a more than 95 percent success rate in treating dogs with this type of arrhythmia.

Dogs know when they don't know

Researchers have shown that dogs possess some 'metacognitive' abilities -- specifically, they are aware of when they do not have enough information to solve a problem and will actively seek more information. The researchers created a test in which dogs had to find a reward behind one of two fences. They found that the dogs looked for additional information significantly more often when they had not seen where the reward was hidden. View the source article

Prototype of robot dog nose

Every day, thousands of trained K9 dogs sniff out narcotics, explosives and missing people. These dogs are invaluable for security, but they're also expensive. Researchers have made the beginning steps toward an artificial 'robot nose' device that officers could use instead of dogs. The heart of the system would be living odor receptors grown from mouse genes that respond to target odors, including the smells of cocaine and explosives. View the source article

Geneticist solves long-standing finch beak mystery

Biologist have compared the genes of large-beaked Cameroonian finches to those of their smaller-beaked counterparts, found the answer to a 20-year old mystery: 300,000 base pairs, apparently inherited as a unit, always varied between them, and right in the middle of that genetic sequence was the well-known growth factor, IGF-1.

No link between 'hypoallergenic' dogs and lower risk of childhood asthma

Growing up with dogs is linked to a lower risk of asthma, especially if the dogs are female, a new study shows. However, the researchers found no relation between 'allergy friendly' breeds and a lower risk of asthma. View the source article

Dogs detect malaria by sniffing socks worn by African children

As the global battle against malaria stalls, scientists may be adding a novel tool to the fight: sniffer dogs. In recent tests trained sniffer dogs successfully diagnosed malaria infections simply by sniffing samples from socks worn briefly by children from a malaria endemic area of West Africa, according to a new study.
