Super-sniffing elephants

Like Aesop’s fable, rats have another reason to be envious of elephants. Elephants also have significantly more genes that can detect different smells (i.e. olfactory receptor genes) than other super-sniffers like rats and dogs. In fact, compared to 13 other species, African elephants have 1,948 genes related to smell putting them ahead of the previous…

Heroic cats

Just in case you have not seen this viral YouTube video of the family cat saving a boy from a vicious dog attack, I have embedded it below. I think this kitty deserves a nice fresh fish for dinner…every day. An article was posted today in NBCNews featuring the heroics of other house cats. Here…

Day 3 of the Experimental Biology meeting was arguably one of the most exciting for comparative physiology. Here are the highlights from Monday: Morning Seminars: Birgitte McDonald from Aarhus University, Denmark presented, “Deep-diving sea lions exhibit extreme bradycardia in long-duration dives.” Birgitte and Dr. Paul Ponganis measured the heart rate of California sea lions (Z.…

New discovery about dog eyes

I came across this really interesting press release from the University of Pennsylvania that I just had to share. Despite having a close relationship with dogs for thousands of years, we are still making new discoveries about our canine friends. Drs. William Beltran (School of Veterinary Medicine), Artur Cideciyan (Perelman School of Medicine), and colleagues…

A paper published in Current Biology describes research using functional magnetic resonance imaging (fMRI) to compare the sound processing regions of brains in humans and dogs (border collies and golden retrievers). The subjects listened to almost 300 sounds (vocalizations from dogs and humans as well as non-vocal sounds) or no sound as a control. They…

Scientists have identified the origin of a genome for a specific type of transmissible cancer that has spread between dogs beginning 11,000 years ago!

A dog’s compass

Okay, here is something rather interesting that I came across today. Scientists have discovered that dogs will align their bodies with the Earth’s magnetic field before excretion. What is even more amazing is that the scientists actually observed over 5,000 pee breaks and over 1,800 defecations to come to this conclusion. Their findings suggest that…

I came across this interesting technology to communicate with dogs that I just had to share. A research team at Georgia Tech has come up with the idea of creating a high-tech vest for assistance dogs to better communicate with their owners. The project is called FIDO (Facilitating Interactions for Dogs with Occupations). The vests…

The FDA is calling for help to determine the source of roughly 580 deaths and over 3600 illnesses (gastrointestinal and kidney) related to jerky treats that were made in China. The  mystery dates back to 2007 when illnesses were first being reported by pet owners.  Most of the victims have been dogs, although 10 cats…
