Airborne pheromone produced by tsetse flies

Posted by Robin on 27 February 2023 2 Comments

Biologists recently discovered the first airborne pheromone produced by tsetse flies. The finding, reported in Science, promises new control methods for the biting flies, which have a long history of spreading devastating diseases across Sub-Saharan Africa.

“The best way of controlling these horrible diseases is by controlling the flies,” says senior author John Carlson, a neuroscientist at Yale University in New Haven, CT. Traps baited with cow urine are the current mainstay of tsetse control. Adding fly pheromones to the traps could lure more tsetse.

The smell of other geckos

A novel study found that geckos use the smell of other geckos to differentiate them from other members of their species, a University of Bern published early February determined.

The study, published in the peer-reviewed scientific journal Animal Cognition by Springer, discovered that Geckos actually use their tongues to sense the odor of other gecko subspecies.

Olfactory dysfunction

Posted by Robin on 22 February 2023 5 Comments

Exposure to PM2.5 – the collective name for small airborne pollution particles, largely from the combustion of fuels in vehicles, power stations and our homes – has previously been linked with "olfactory dysfunction", but typically only in occupational or industrial settings. But new research is now starting to reveal the true scale – and the potential damage caused by – the pollution we breathe in every day.

The perceived relative pleasantness of odorants

Posted by Robin on 17 February 2023 Leave a Comment

"Critically, across cultures, the perceived relative pleasantness of odorants seems to be equally robust—our effects are not driven by the peculiarities of one or two odorants or limited by the sample size of participants. This is striking and is contrary to what would have been predicted from a cultural relativity perspective,” the authors wrote.

— Researchers look at the influence of culture on odor preference. Read more in What’s Your Favorite Smell? at Psychology Today.

Stinky body odors

Posted by Robin on 9 February 2023 Leave a Comment

It wasn't that our extinct relatives could smell scents undetectable to humans, or vice versa. Instead, the Denisovan turned out to have a more sensitive nose than humans, while Neanderthals seemed to have weaker noses — especially, in one group, for stinky body odors.
