This Week's Letters

Laboratories in South America disagree over who discovered that there is a common variant in the Y chromosomes of native American men. A reader questions why an actor who played a doctor on television should testify before the U.S. Congress on behalf of medical research. "This strategy...is the logical result of attitudes displayed in an old television advertisement ('I'm not a doctor, but I play one on TV')...." Thoughts about how to encourage interdisciplinary research are offered. A reader wonders whether ancient cave painters were affected by carbon monoxide poisoning. The relationship between the genome and aging is explored. And an article about peptide bond formation is retracted.
