    This article describes attempts to use ketones as a substitute for glucose when it’s unavailable to the brain because converted fats can’t penetrate the brain. Wouldn’t it be simpler to feed or inject glucose directly? Oliver H. WinnCorona del Mar, Calif. The researchers who conducted the study say that giving glucose might help in some […]

    Your article uses the words “placebo therapies such as supportive counseling.” I think that people in the profession and people who have been paying for such therapy would disagree with the characterization. Also, the various permutations of treatment covered in the article didn’t include a very common one: drugs without any serious counseling. In such […]

    This article describes the use of the mosquito-borne Sindbis virus to kill cancer cells in lab dishes and mice. It would be interesting to determine whether the human population of the Egyptian town of Sindbis exhibits a reduced incidence of certain cancers. Perhaps large-scale efforts directed toward elimination of the mosquito in populated areas are […]

    Unfortunately your article got something wrong in describing the reshaping of aircraft surfaces. It states, “The recently retired supersonic commercial transport, the Concorde, tilted its nose downward for subsonic flight.” This is not the (whole) truth because the reason for this reshaping was not to reduce air drag, but to achieve a far-better view of […]

    Nice to know that someone is scanning kids’ skulls for attention-deficit hyperactivity disorder (ADHD). The essential problem with this sort of thing is that psychology and psychiatry are descriptive endeavors and particularly flexible when it comes to describing ADHD. It’s unlikely that all the behaviors associated with the syndrome have a common physiologic structure. This […]

    Your article states, “There are about 4.14 kilograms of carbon in a gallon of gasoline, says Dukes.” If he actually said that, this would seem to qualify this gasoline as an “alternative fuel,” since a gallon of ordinary gasoline is only about 2.5 kilograms in mass. Perhaps Dukes meant 4.14 pounds of carbon per gallon. […]
