Medical Discovery News
Science permeates everyday life. Yet the understanding of advances in biomedical science is limited at best. Few people make the connection that biomedical science is medicine and that biomedical scientists are working today for the medicine of tomorrow. Our weekly five-hundred-word newspaper column (http://www.illuminascicom.com/) and two-minute radio show provide insights into a broad range of biomedical science topics. Medical Discovery News is dedicated to explaining discoveries in biomedical research and their promise for the future of medicine. Each release is designed to stimulate listeners to think, question and appreciate how science affects their health as well as that of the rest of the world. We also delve into significant biomedical discoveries and portray how science (or the lack of it) has impacted health throughout history.

Cats and Smell
Welcome to Medical Discovery News. I’m Dr Norbert Herzog.
And I’m Dr. David Niesel
Does your cat spend a lot of time sniffing everything around her? Mine does—especially my shoes! Sniffing is a way cats explore, and now a new study from Tokyo helps us understand how they respond to scent.
Thirty cats in the study were filmed responding to their owner’s scent against a stranger’s and to keep stress levels low and to persuade them to participate, the study was done in their homes.
Humans in the study were told to swab behind their ears, toes, and underarms and to avoid eating pungent foods or wearing perfume. Then each sample was sealed in separate plastic tubes.
On average, the cats spent about two and a half seconds on their owners’ tubes but twice as long on the strangers’ tubes. Most cats all but ignored the blank tubes.
When sniffing a strange scent, the cats were seen favoring their right nostril, then switching to the left as it became more familiar.
Dogs and horses do this too, which could imply that the right brain processes new or alarming smells and the left brain deals with familiar ones.
The cats were also seen rubbing the plastic tube with the same cheek as the sniffing nostril to mark the object as theirs just as they do to you.
And just like humans, a cat’s personality played a role. Neurotic cats sniffed furiously the blank or familiar tubes first, while agreeable cats calmly sniffed out the strange or blank scents first. Aren’t most cats neurotic
Since cats remain largely a mystery to us, this work helps to unlock the behaviors of our furry companions and confirms other studies that show cats are in tune with their humans! And they can be just plain weird.
We are Drs. David Niesel and Norbert Herzog, at UTMB and Quinnipiac University, where biomedical discoveries shape the future of medicine. For much more and our disclaimer go to medicaldiscoverynews.com or listen to our podcast on your favorite podcast service.
