The John Horgan George Johnson video blog has good commentary on current scientific news. Among other things:
Females bear grudges more than males. My pet theory attributed this to boys playing team sports, but Horgan says that the same thing has been observed in monkeys, chimps, and bonobos.
The new studies are puzzling, and the old ones on things like the Flynn Effect still have no good explanation.
Evolution by natural selection is a tautology. There won't be any more paradigm shifts because evolution can absorb any truths that might be discovered.
