We each live in our own little world -- smellwise

[unable to retrieve full-text content]There are some smells we all find revolting. But toward a handful of odors, different people display different sensitivities. A pair of studies identifies the genetic differences that underpin the differences in smell sensitivity. The researchers tested 200 people for their sensitivity to 10 different chemical compounds. They then searched through the subjects' genomes for areas of the DNA that differed between people who could smell a given compound and those who could not.
