Scientists from Baylor College of Medicine and elsewhere say they have discovered subfossils of ancient chromosomes in the remains of a female woolly mammoth (Mammuthus primigenius) that died 52,000 years ago in what is now Siberia. The fossils preserve the structure of the ancient chromosomes down to the nanometer scale — billionths of a meter. The researchers hypothesize that the mammoth skin spontaneously freeze-dried in the Siberian cold,...

Plant induced responses to environmental stressors are increasingly studied in a behavioral ecology context. This is particularly true for plant induced responses to herbivory that mediate direct and indirect defenses, and tolerance. These seemingly adaptive alterations of plant defense phenotypes in the context of other environmental conditions have led to the discussion of such responses as intelligent behavior. In their paper, Kessler & Mueller consider the concept of plant intelligence and some of its predictions for chemical information transfer in plant interaction with other organisms.
