ScienceDaily: Dog News Veterinary research and news on dogs as companions, canine health, wolf pack behavior and more. If it is news about dogs, you will find it here! Ancient domesticated dog skull found in Siberian cave: 33,000 years old A 33,000-year-old dog skull unearthed in a Siberian mountain cave presents some of the oldest known evidence of dog domestication and indicates that modern dogs may be descended from multiple ancestors, with advancing glaciers thwarting early domestication efforts. Gene therapy cures retinitis pigmentosa in dogs Scientists have shown that they can prevent, or even reverse, a blinding retinal disease, X-linked Retinitis Pigmentosa, or XLRP, in dogs. The disease in humans and dogs is caused by defects in the RPGR gene and results in early, severe and progressive vision loss. It is one of the most common inherited forms of retinal degeneration in man. Love of a dog or cat helps women cope with HIV/AIDS A spoonful of medicine goes down a lot easier if there is a dog or cat around. Having pets is helpful for women living with HIV/AIDS and managing their chronic illness, according to a new study. How the 'street pigeon' got its fancy on Pigeons come in all colors, shapes, and sizes. Some have feathers reaching up over their heads like a hood. Others have feathers all the way to the tips of their toes or fanned out on their tails like tiny turkeys. Now, researchers have traced the birds' family tree in an effort to sort out how all that remarkable variation came to be. Birds of a feather don't always stick together Pigeons display spectacular variations in their feathers, feet, beaks and other physical traits, but a new study shows that visible traits don?t always coincide with genetics: A bird from one breed may have huge foot feathers, while a closely related breed does not; yet two unrelated pigeon breeds both may have large foot feathers. Saving dogs with spinal cord injuries Dogs with spinal cord injuries may soon benefit from an experimental drug currently being tested by researchers ? work that they hope will one day help people with similar injuries. Dogs read our intent Dogs pick up not only on the words we say but also on our intent to communicate with them, according to a new report. An ecosystem being transformed: Yellowstone 15 years after the return of wolves On the 15th anniversary of the return of wolves to Yellowstone National Park, a quiet but profound rebirth of life and ecosystem health is emerging, scientists conclude in a new report. Pet kidney injuries are similar to human kidney injuries For pets suffering critical illness or injury, researchers have found that even tiny increases of creatinine in blood also could indicate acute kidney damage. Using human blood measurement guidelines for acute kidney injuries, the researchers believe they can now help pet owners better know the severity of their animals' illness. Fungus-induced neurological disease: An underestimated risk for animals and h... The mold fungus Penicillium crustosum occurs relatively frequently in food and animal fodder stored in temperate conditions. This mold produces powerful neurotoxins, for example penitrem A, which causes symptoms that are difficult to distinguish from those of other neurological diseases. Penitrem A is capable of penetrating the blood-brain barrier and new research has unveiled the mechanisms behind the neurological effects of the toxin. Shedding light on why it is so 'tough' to make healthier hot dogs In part of an effort to replace animal fat in hot dogs, sausages, hamburgers and other foods with healthier fat, scientists are reporting an advance in solving the mystery of why hot dogs develop an unpleasant tough texture when vegetable oils pinch hit for animal fat. Veterinarians find infections faster by monitoring blood compound; Blood test... In pets and people, the time it takes to diagnose an infection may mean life or death. Now, a veterinarian is identifying ways to diagnose pet infections in approximately a third of the current diagnosis time. Powerful mathematical model greatly improves predictions for species facing c... Life scientists have produced the most comprehensive mathematical model ever devised to track the health of populations exposed to environmental change. New insights into responses of Yellowstone wolves to environmental changes A study of the wolves of Yellowstone National Park has improved predictions of how these animals will respond to environmental changes. The study, which is part of the Yellowstone Wolf Project, involved tracking changes in various characteristics of the wolves of Yellowstone National Park ever since these animals were reintroduced to the park in 1995. Scientists unlock the mystery surrounding a tale of shaggy dogs Researchers have produced the first clear evidence that textiles made by the indigenous population of the Pacific coast of North America contained dog hair.
