Scientists have developed an artificial intelligence system that can predict how humans perceive smells based on their chemical structures. The Smell AI system uses deep learning to analyze millions of molecular features and odour descriptions and generate new odor labels for unknown molecules. The system could help create new fragrances, flavors, and aromatherapy products and improve our understanding of the sense of smell.

"the program, a so-called graph neural network, is excellent at imitating human sniffers, at least when it comes to simple odors. It reliably predicted what the volunteers smelled, a feat sensory biologists have been working toward for decades. It also predicted the smells of 500,000 other molecules, with no need to make or sniff them."

Looking forward to talking to the UK Semiochemical Network meeting tomorrow about ‘Individuating the Sense(s) of Smell’. For further details, you can read the published version at doi.org/10.1007/s11229-020-029.

There were plenty of great talks at yesterday, but I think my favorite was Robert Driver's work on olfactory receptors in birds. It was great to see someone pushing back on the "birds can't smell" narrative with cutting edge genomics and functional genetic techniques!

“The functional logic of odor information processing in the Drosophila antennal lobe", Lazar et al. 2023
journals.plos.org/ploscompbiol

A computational model of olfactory circuits based on and functional data, which separates semantic information (which odor; quality) from syntactic (intensity; quantity) using known sensory neurons, projection neurons and local neurons.

Long COVID Smell Loss Linked to Changes in the Brain

Anosmia, or the loss of the sense of smell caused by long COVID is linked to changes in the brain that prevents correct olfactory processing.

“Mechanisms and functions of respiration-driven gamma oscillations in the primary olfactory cortex”
González et al. 2023 elifesciences.org/articles/830

“respiration drives gamma oscillations in the piriform cortex, which correlate with local feedback inhibition… [oscillations] locally segregate neuronal assemblies through a winner-take-all computation leading to sparse odor coding during each breathing cycle.”

Part of the joy of sitting down with a good is the experience of it: the heft of the book in your hands, the sound of the cracking spine as you open it, the texture of the pages, and the telltale aroma that distinguishes between new and old. Here's where those smells come from (h/t: mstdn.social/@compoundchem, in honour of in the UK).

Next was a fantastic talk by Stuart Firestein on the science of human and modeling at @sfiscience. I've always been curious about why it's so difficult to build machines that can effectively smell, and this talk clearly lays out why - we still don't completely understand how people . The details here are fascinating, and highly worth your time youtube.com/watch?v=3UqAo3gETk (5/7)
