New research suggest that the Siberian woolly mammoth lived in two distinct clans. Scientists are trying to determine why the groups appeared to live in the same region but went extinct at two different times.
The axolotl salamander is one of the few vertebrates that can regenerate entire limbs as an adult. Scientists are now sequencing parts of its unusually large genome in order to understand the genetic basis for this ability.
Scientists have sequenced Salinispora tropica, a species of ocean bacteria. S. tropica produces compounds such as salinosporamide A, which has shown promise in the treatment of bone marrow cancer and solid tumours.
