Olfaction: Smells Like Fly Food

Fruit flies love foods containing yeast. A new study now shows that they are attracted to and have dedicated olfactory neurons for detecting the scents produced by yeast metabolizing common phenolic compounds in fruit.

Demixing smells — fast inference in olfaction Supplementary Material

Because of the delta-function in the prior, performing efficient variational inference in our model is, as far as we know, difficult. Therefore, we smooth the delta-function, and replace it with a Gamma distribution, δ(cj) −→ Γ(cj |α0, β0). In the limit α0 → 0 and β0 → ∞ we recover the true prior. However, when these two parameters are finite, absent odors – odors with sj = 0 – have non-zero co...

Smells Like the Real Thing

Whether bulbous, Roman, or pug, the nose gets all the credit. But the actual star of smell is an unassuming patch of tissue, several centimeters square, tucked up inside each nasal cavity. After a whiff of a peach or a lilac, this tissue captures the volatile chemicals traveling into each nostril. The chemicals bind to receptors on the tissue's millions of neurons, the neurons relay the informa...

Evolutionary Genetics: Smells like a Pseudo-pseudogene

A new study reports the presence of a chemosensory pseudogene in Drosophila sechellia, which in spite of carrying a premature stop-codon nevertheless encodes a fully functional and full-length protein. Such 'pseudo-pseudogenes' might well be a widespread phenomenon.

Food neophobia and its relation with olfaction

Food neophobia, that is the reluctance to try novel foods, is an attitude that dramatically affects human feeding behavior in many different aspects among which food preferences and food choices appear to be the most thoroughly considered. This attitude has an important evolutionary meaning since it protects the individual from ingesting potentially dangerous substances. On the other hand, it f...
