We show evidence that 1 of the 18 elements regulates the expression of ASXL3 during development by encoding an alternatively spliced exon that causes nonsense-mediated decay of the transcript. The retroposon that g...
متن کاملRemoving protected populations to save endangered species.

A complex example relates to the decline of the island fox (Urocyon littoralis), endemic to the California Channel Islands, off the coast of the United States. The island fox exists as six subspecies, each found on a separate is...
متن کاملGoing to bat for an endangered species.
www.sciencemag.org SCIENCE VOL 336 1 JUNE 2012 1073 COVER Three-dimensional computer models such as this one help researchers explore the mechanisms behind core-collapse supernovae, the violent death of short-lived massive stars. In the image, tubes represent paths of gas falling into a supernova, defl ected by an accretion shockwave (horizontal width of 600 km); colors represent different velo...
