Unlike some, I find no problem with the idea of hybrids between ancestors of chimpanzees and humans. We have to assume that any speciation event will be protracted. The collection of genes that separate humans from apes would hardly have arisen in a single individual. From my study of dabbling ducks, I have come to […]

Regarding the “new humanmade version of an insect’s compound eye,” it has been obvious for many years that such structures need not be exceptionally small and need not be extremely like ommatidia to behave like ommatidia. Triads of small light sensors can be arrayed in large, wide, and slightly concave or convex panels and hardwired […]

It would seem to me that instead of looking to minimize the effect of grapefruit juice in slowing the metabolism and elimination of drugs, one could cut drug dosages by taking advantage of it. Grapefruit juice costs less than any drug and has far fewer possible side effects. This could only benefit the patient by […]
