A new dating service that launched this week for Boston-area singles claims that it can get the chemistry right when fixing up potential mates—literally.

In sniff tests of dirty t-shirts, people tend to be most attracted to the scent of the shirt whose owner has different MHC alleles from the sniffer.

For $1,995 and a cheek swab sent off for DNA analysis, customers can find the love of their lives, or so says Eric Holzle, a Massachusetts engineer and long-time dater. Kerry Grens spoke to him on December 11, the day the site went live. At the time, he was driving, and didn't know if anyone had signed up.
