Latest Olfactory receptor Stories
New research from the University of California, Davis has identified the precise odorant receptor in mosquitoes that bonds with DEET and results in the bugs being repelled, according to a new study in the journal Proceedings of the National Academy of Sciences.
In a study published this week in Genome Research, researchers examined the olfactory receptor (OR) repertoire encoded in 13 mammalian species and found that African elephants have the largest number of OR genes ever characterized.
Scientists from the Technische Universität München and the German Research Center for Food Chemistry performed a meta-analysis on the odorant patterns of 227 different food samples to try and understand why and how a certain food smells the way it does.
To accommodate a lifetime of scents and aromas, mammals have hundreds of genes that each produce a different odorant receptor.
The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents.
Odorant receptors of recent insects evolved long after insects migrated from water to land.
For decades, experts have claimed that people were capable of detecting 10,000 different odors, but new research appearing in March 21 edition of Science suggests that the actual number of scents detectable by the human nose is considerably higher.
People react differently to the same smells. Something that smells wonderful to you could be offensive to your friend, but why this is so has been a mystery. The answer could lie in your genetic makeup, says a research team from Duke University.
According to Gertrude Stein, "A rose is a rose is a rose," but new research indicates that might not be the case when it comes to the rose's scent.
Environmental stimuli often trigger our sense of smell before we exhibit any other response. Smells trigger neurons in our brains that alert us to take action, but there is often more than one odor in our environments at any given time.
