The interiors of giant planets: Models and outstanding questions
Article Abstract:
The discovery of giant planets orbiting other stars is an opportunity to learn more about these objects their composition, the way in which these processes influence their structure and evolution and the way they form. The intercomparison of presently characterized extrasolar giant planets shows that they are made of hydrogen and helium, but they either have different amounts of heavy metal elements or different orbital evolutions or both.

Dates and rates: Temporal resolution in the deep time stratigraphic record
Article Abstract:
The temporal resolution of the stratigraphic record in deep time is reviewed and the focus is on the growing ability to resolve absolute time rather than differences in relative time. An attempt is made to quantify the ubiquity of gaps in the stratigraphic record and it is showed that the finer the temporal resolution sought, the less sediment was actually preserved.
