    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...

    Salmon Safety

    Two recent reports urge more fish consumption, including farmed salmon. But previous studies had warned against farmed salmon because of high levels of organic pollutants. So, do we eat it or don't we?

    A report published in Science 3 years ago warned that some kinds of salmon should be eaten at most once every 5 months. But in October 2006, an article in the Journal of the...

    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.

    Potent Medicine

    The test for the boys and girls was simple: to cover as much ground as they could in 6 minutes. But these children, ages 5 to 18, had pulmonary hypertension—high blood pressure in their lungs from constricted blood vessels. Such kids "don't have a lot of energy," explains pediatric cardiologist Tilman Humpl. "They can't exercise at all. They may not be able to walk up from the basement to the...

    Fighting off the viruses

    A couple of decades ago, if someone had asked whether you'd heard about "that new virus," you'd have know that they were concerned about a health threat. This year, you'd have needed to ask, "Medical or computer?" On both viral fronts, 2003 was eventful. A new viral disease emerged in China, and...
