Latest Olfactory system Stories
Studies have found many predictors of death in the elderly, including broken hips, love handles and nocturia. For older adults, a loss of smell is also a strong predictor of death within five years, according to University of Chicago researchers.
For many animals, making sense of the clutter of sensory stimuli is often a matter or literal life or death.
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.
A spinal mass was identified in a young woman with complete spinal cord injury 8 years after she had undergone implantation of olfactory mucosal cells in the hopes of regaining sensory and motor function.
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.
While scientists know that a superfamily of genes inside olfactory receptors is responsible for our sense of smell – we still don’t know the mechanism behind the interpretation of odor molecules into a particular smell.
