Researchers from the Monell Chemical Sense
Center in Philadelphia and from Tokyo University of Agriculture have used a novel molecular method to identify chemical compounds from common foods that activate human bitter taste receptors.
Although the ability to detect and respond to chemical cues is essential in most animals, we know very little of how the chemical sense
will be affected by the rapid environmental changes we face today.
While many aspects of other chemical senses
like taste and smell have been independently invented multiple times over the course of animal evolution, the chemical sense
that detects these reactive compounds is different," said study author Paul Garrity, a biologist at Brandeis University in Waltham, Mass.
It "does the same thing, in a chemical sense
, as the protein enzymes.
You essentially toss the atoms in a shoebox with enough chemical knowledge to make sure the arrangement makes chemical sense
," Miller says.
Sowing vegetables is easy really, so long as you remember each plant "knows" its neighbour is there in a chemical sense

Michelle Gallagher, a chemist at Monell Chemical Senses
Centre in Philadelphia, took the inspiration for her experiments from stories that dogs could sniff out cancers.
The fourth edition contains substantial revisions of chapters on the somatic sensory system, the visual systems, the chemical senses
, upper motor neural control, the basal ganglia, and sex and sexuality, as well as brand new chapters on synaptic plasticity and repair and regeneration in the nervous system.
