Also, in Kenya, an invading ant species pushed out ants that protected acacia trees. That had cascading effects for elephants, zebras, lions, and buffalo.A ‘Jeopardy!’ Winner Studied How Trivia Experts Recall FactsWhen contestants play “Jeopardy!,” it can be amazing to see how quickly they seem to recall even the most random, obscure facts.
