Article Abstract:
China's science policy can be opaque to the Chinese community and the outside world and hampered by lack of coordination, but is ultimately successful in delivering enhanced resources and quality. The announcement of plans to revamp the Chinese Academy of Science (CAS) research activities has come as a surprise to some, due to the sheer scale of the proposals. The Academy is still an important source of much of the country's best science, but there are concerns about the lack of ability to retain younger scientists due to the low salaries and lack of software support.

Article Abstract:
A comparison between climate records from high latitudes, subtropical regions and the tropics, indicating that the onset of large glacial/interglacial cycles did not coincide with a specific climate reorganization event at lower latitudes is presented. The comparison between records from high latitudes reveals that high -latitude climate sensitivity to variations in solar heating increased gradually, culminating after cool tropical and subtropical upwelling conditions established two million years ago.

Article Abstract:
Sapropels are organic-matter rich layers and are common in Neogene sediments of the eastern Mediterranean Sea. Eastern Mediterranean Pliocene sapropels were found to contain molecular fossils of isorenieratene which can be synthesized by photosynthetic green sulphur bacteria. Such sapropels have high trace metals content. It is concluded that water column euxinia occurred over substantial periods of Paleocene sapropel formation and that degradation influenced the euxinic conditions.
