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.

Local Varmints

Was taking a walk around our neighborhood lake one recent morning and noticed a trio of river otters having breakfast and sporting around.  In other sightings... A creek runs alongside the footpath and one morning I heard the *thwack* of a beaver slap. I watched the creek for a while and sure enough a beaver glided by on its back. It was gone by the time I fumbled out my phone so I never got a photo of it never mind a video.  Whenever I walk in the mornings I listen and look

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.

Glyphosate found in cat and dog food

A new study finds that glyphosate, the active herbicidal ingredient in widely used weed killers like Roundup, was present at low levels in a variety of dog and cat foods the researchers purchased at stores. Before you go switching Fido or Fluffy's favorite brand, however, be aware that the amounts of the herbicide found correspond to levels currently considered safe for humans. View the source article
