I offer no defense of the sex offenders described in your article. They merited punishment. However, the article emphasizes the reliability of the children’s statements. Did the questioners see the evidence prior to the questioning? Any surveyor of public opinion or interviewer knows that the answers given are greatly influenced by the timing of questions, […]

Your article reports that chemically synthesized erythropoiesis protein (SEP) was more effective than the genetically engineered molecule. Is there speculation on why that is? Ann DershowitzWest Orange, N.J. Chemically constructed SEP molecules are much more consistent in size, shape, and other properties than genetically engineered erythropoietin. The polymer appendages put onto the molecule protect SEP […]

I am puzzled by Shuming Nie’s prognostication that quantum dots will “be the first example of nanotechnology that can really have some practical applications.” Colloidal gold particles of similar size to quantum dots have been used as high-resolution labels in electron microscopy for over 30 years. And due to their light-scattering properties, gold and silver […]

Years of budgetary constraints and compromises have all but destroyed NASA’s ability to deliver on the grand visions of yesteryear. Sadly, I think that the best outcome of this tragedy would be to acknowledge that the shuttles are unsafe at any speed. Perhaps the national embarrassment is just what the U.S. government needs to get […]

This article makes disturbing use of Neal Barnard as a spokesman warning against the high-protein weight-loss diet. Barnard represents Physicians Committee For Responsible Medicine (PCRM). What’s not to love about an outfit with a name like that? PCRM places op-ed pieces condemning animal products, and it advocates a vegan agenda. A more balanced response might […]

I wish the testing described in this article had used airline pilots, policemen, and other people who are accustomed to operating their machines while carrying on a conversation. Cell phones are new, and perhaps all that is needed is time for drivers to train themselves in multitasking. Mike KuzaraWyarno, Wyo. Shortly after reading the article, […]

I scuba dive, and I’ve noticed that when the current is brisk through some coral formations, small swirls behave exactly as dust devils. Would the researchers predict that any magnetic phenomena could be produced by silt in salt water? Lindsey Randal Potts San Antonio, Texas Probably not, says William M. Farrell of NASA. Any charges […]

Your article refers to “the current theory that high intelligence arises from the coating of brain cells with especially large amounts of the fatty substance called myelin.” As a person with multiple sclerosis, anything about myelin interests me greatly, yet I have never heard of this. Marion Leeds Carroll Arlington, Mass. For more, see Daniele […]

Erik Trinkaus argues that fossil evidence shows signs of considerable interbreeding of Neandertals and modern humans. However, I don’t believe that proves we could have Neandertal ancestors. Couldn’t crossbreeding result in sterile offspring, such as is seen in mules? Anne Wittke Flagstaff, Ariz. Sure. Trinkaus argues, however, that the presence of Neandertal traits on the […]

I think that your readers should be aware that this article on beach erosion is based upon a report by the Heinz Center for Science that’s being widely disputed. Susan Halsey’s opinion that nothing can be done to stop these losses is in direct conflict with a National Research Council report, “Beach Nourishment and Protection,” […]

Your article says that “lactose, a sugar in milk, commonly elicits allergic reactions.” Lactose and many other carbohydrates don’t elicit an allergic response. Jonathan StapleyWest Lafayette, Ind. Lactose intolerance is the inability to digest significant amounts of lactose because there’s a shortage of an enzyme that breaks down milk sugar. This condition shouldn’t have been […]

I was encouraged to read this article. I’ve often wondered when researchers outside addiction research would realize type II diabetes is the result of addiction to foods that chronically elevate insulin levels, thus acting as antidepressants. Once physicians recognize carbohydrate abuse as drug abuse, we’ll be better situated to provide appropriate interventions. Betty Streett Clarksdale, […]
