Cats respond differently to the scents of their owners

Posted by Robin on 29 May 2025 2 Comments

But in a study published on Wednesday in the journal PLOS One, Dr. Uchiyama and his team managed to achieve some research findings in feline behavior, establishing that cats respond differently to the scents of their owners than to the odors of strangers. That suggests your feline friend knows what you smell like, in addition to what you look and sound like.

Smell preferences

Posted by Robin on 22 April 2025 Leave a Comment

When you meet a stranger for the first time, how do you judge your potential to be friends? Is it their personality? Their style? Their smile? According to a new study in Scientific Reports, scent might have something to do with it, as smell preferences can predict whether people see each other as potential friends.

Make me hate some of my favorite perfume

Posted by Robin on 18 April 2025 3 Comments

When I started taking a GLP-1 medication in October, I knew it would probably change a few things—our weekly dinner plan, how my pants fit, my relationship to alcohol (initial research shows low-dose GLP-1 drug patients drink less of it). What I didn’t know was that it would make me hate some of my favorite perfumes.

An odor-detecting drone

Posted by Robin on 10 April 2025 2 Comments

Researchers in Japan have developed an odor-detecting drone that uses antennae taken from insects.

The “insect drone” can autonomously find its way to the source of an odor.

The researchers hope that by expanding the range of the drone’s odor detection, and ultimately enabling it to detect the scent of humans, the device can be a useful tool for search and rescue missions at disaster sites.

A simple passive system

Posted by Robin on 18 February 2025 Leave a Comment

Before Olofsson started his research, he “viewed the sense of smell as a simple passive system” in which airborne molecules attach to mucosa in the nasal cavity, setting off a biological chain reaction that leads to a smell sensation in the brain. Now, he realises, “olfactory processes start not in the nose but in the brain, even before the odour molecules reach their destination. Olfactory processes are shaped by expectations and experiences.”

— The Financial Times, on the new book The Forgotten Sense: The New Science of Smell by Jonas Olofsson. Read more in The Forgotten Sense — why do we underestimate the power of smell?; hat tip to Kevin!

Florian Mormann, lead author on the study, told Salon in a video interview from Bonn that “the surprising finding to us was that we found cells that responded both to an odor and to the picture … of an object that is associated with the odor. For example, the smell of a banana, the picture of a banana and the written word ‘banana.’”
