Technique traces origins of disease genes in mixed races

A team of researchers from Washington University in St. Louis that includes Alan R. Templeton and the Israeli Institute of Technology (Technion) in Haifa has developed a technique to detect the ancestry of disease genes in hybrid, or mixed, human populations. The technique, called expected mutual information (EMI), determines how a set of DNA markers is likely to show the ancestral origin of locations on each chromosome.

Ugly duckling mole rats might hold key to longevity

WUSTL biologist Stan Braude, working on a book about the critters, says the naked mole rat is being studied for its tendency to live a long life.Who would have thought that the secrets to long life might exist in the naked, wrinkled body of one of the world’s ugliest animals? Probably not many, but current research may be leading seekers of the Fountain of Youth to a strange little beast — the naked mole rat.
