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…

City birds are early to rise

A recent study has provided some evidence supporting the hypothesis that light and noise pollution alters the biological clocks of birds living in cities (compared to birds living in rural areas).   Dr. Dominoni (Max Planck Institute for Ornithology, Germany) and colleagues used radio-pulse transmitters attached to European blackbirds (Turdus merula) living in Munich, Germany…

Dr. Kerstin Lindblad-Toh at Uppsala University (Sweden) who specializes in comparative genomics and Dr. Åke Hedhammar, SLU (Sweden) recently identified a novel gene in German shepherd dogs, PKP-2, that encodes a protein (plakophilin-2) important for regulating proper skin structure and function. This protein was found to be associated with canine atopic dermatitis (i.e. doggy eczema), a…

Humans vs. Dogs

I just watched a funny entry submitted for the 2012 American Physiological Society’s (APS) video contest on some of the differences betweens humans and dogs. The authors of the video were Nate Brault and Thomas Szamocki from Beloit College. It is also available in the APS Archive of Teaching Resources, a searchable archive of teaching…

One step closer to restoring hearing

Damage to the auditory nerve connecting the inner ear and brain causes hearing loss in some individuals. Researchers Dr. Marcelo Rivolta from the University of Sheffield and colleagues have shown that human embryonic stem cells that were differentiated into auditory nerve cells can improve overall by ~45% hearing in gerbils that were treated with ouabain to damage the…

You may recall a prior post in which I talked about how intelligent crows are. In fact, there was a special on PBS demonstrating their ability to solve problems and even recognize human faces (HIGHLY recommended if you haven’t yet had a chance to see it): Watch A Murder of Crows on PBS. See more from Nature. In a…

The uniqueness of humans

I just watched this neat presentation given a few years back by Dr. Robert Sapolsky from Stanford University on the differences and similarities between humans and animals:

…you receive comments from reviewers stating that your “research is interesting, but what does it have to do with people?” Clearly these reviewers have not been reading this blog or they would know that many of the findings in animals have the potential to benefit humans although some findings really are destined to only benefit…
