---THIS WEEK'S HIGHLIGHTS:

--Biological Sciences
-Self-organizing optic-cup morphogenesis in three-dimensional culture
Clusters of mouse stem cells organize themselves into layered structures
resembling the optic cup, a precursor of the embryonic eye, and then
form fully stratified retinal tissue. This has important implications
for regenerative medicine.

--Earth & Environmental Sciences
-Low strength of deep San Andreas fault gouge from SAFOD core
Laboratory strength measurements of material from a drill hole located
north-west of Parkfield, California show that the San Andreas fault
is very weak at this location and depth. The cause is an accumulation
of saponite -- one of the weakest phyllosilicate minerals known.

--Earth & Environmental Sciences
-Biodiversity improves water quality through niche partitioning
Experiments involving manipulation of the number of algae species
in model stream systems suggest a mechanism to explain why the
conservation of biodiversity improves the ability of an ecosystem
to retain nutrients and remain productive.

** Electronics: Industry-compatible graphene transistors
Frank Schwierz
An innovative technique has been developed to manufacture graphene
transistors that operate at radio frequencies and low temperatures.
The process brings the devices closer to applications.

** Oceanography: When glacial giants roll over
Anders Levermann
The energy released by capsizing icebergs can be equal to that of
small earthquakes -- enough to create ocean waves of considerable
magnitude. Should such 'glacial tsunamis' be added to the list of
future global-warming hazards?

** Cosmology: A smoother end to the dark ages
Zoltan Haiman
Independent lines of evidence suggest that the first stars, which
ended the cosmic dark ages, came in pairs rather than singly. This
could change the prevailing view that the early Universe had a
Swiss-cheese-like appearance.
