    Amylase with your veggies

    Your article ("Advantage: Starch," SN: 9/15/07, p. 173) notes how groups of people may have different numbers of copies of the amylase gene. Is it correct then that individuals have varying numbers of the gene as well? If so, would this explain why some people don't like meat and become vegetarians and others just need to eat meat?

    How antipsychotic drugs can cause weight gain

    A study of mice has identified a biological mechanism by which certain psychiatric medications cause people to gain weight.

    Researchers linked the appetite-increasing effects of three such drugs—the so-called atypical antipsychotics clozapine (Clozaril), olanzapine (Zyprexa), and risperidone (Risperdal)—to their capacity to neutralize the protein histamine, just as the antihistamine...

    Name game

    "Named medical trials garner extra attention" (SN: 8/5/06, p. 93), I think, has it backwards. It's not that labeled trials are more likely to be funded. Rather, well-funded, large trials are more likely to be named. We research chemists label only the important projects. The name makes the project easier to track and reference.

    Smell the birdie

    I wonder if any of the researchers had a pet bird ("Myth of the Bad-Nose Birds," SN: 8/20/05, p. 120). My Alexandrine parakeet can smell beer or ice cream from two rooms away—She screams for her share.
