---THIS WEEK'S HIGHLIGHTS:

--Biological Sciences
-Activation of the innate immune receptor Dectin-1upon formation of
a 'phagocytic synapse'
Dectin-1, an innate immune receptor on white blood cells, can
differentiate between cell-wall beta-glucans released from microbes
at a distance and those associated with a microbial surface.

--Earth & Environmental Sciences
-On the role of the Agulhas system in ocean circulation and climate
The Agulhas current system around South Africa has a strong role in
ocean circulation and climate as well as a potential role in
stabilizing the Atlantic Meridional overturning circulation

--Biological Sciences
-Shank3 mutant mice display autistic-like behaviours and striatal
dysfunction
Shank3, an autism-associated gene that codes for a key postsynaptic
density protein at glutamatergic synapses, has a crucial role in
neuronal connectivity, suggesting a mechanism for its involvement
in autistic-like behaviours.

Understanding the nature of the first stars, whose formation marked
a pivotal epoch in the Universe's history, is at the frontier of
astronomy. An analysis of stellar data indicates that they were
fast-rotating objects.
