Fst reflects the relative amount of total genetic variation between populations. While there is bound to be a correlation between Fst and species status, Fst is not normally used to define species. An Fst […]

Stem winder “Full Stem Ahead” (SN: 4/2/05, p. 218) showed several reasons why stem cell research is a good thing: Stem cells from embryos might cure cancer, Parkinson’s disease, Alzheimer’s disease, diabetes, and many other diseases. But the article should have included the fact that stem cells may help with transplanting organs. Stem cells may […]

Judging by science “Forensics on Trial” (SN: 3/27/04, p. 202: Forensics on Trial) was an eye-opener. Our courts may be accepting many analytical techniques that haven’t been adequately validated. We should be careful, especially where the death penalty is involved, not to be guilty of hubris in the application of scientific knowledge. Bob SauerPrinceton, Mass. […]

How dingoes got down under
DNA analysis suggests that Australia got its famous dingoes from a very few dogs brought along with people fanning out from East Asia some 5,000 years ago.
