Distant galaxy a Star Factory? 
Galaxy w/ 4.4 Redshift.
Evidence shows stars have formed, lived, and died
spilling their contents out into the interstellar gas.
Observatory @ Rome obtained first images of new galaxy,
tough to detect.
  The most prominent absorption line with the
high redshift is Lyman-alpha from H2 atoms that absorb
quasar's light as it passes.

 MRI Elstography
A nuclear magnetic resonance imaging (MRI) method is presented for 
quantitatively mapping the physical response of a material to harmonic 
mechanical exciation.  The resulting images allow calculation of regional 
mechanical properties.  Measurements of shear modulus obtained with the MRI 
technique in gel materials correlate with independent measurements of static 
shear modulus.  The results indicate that displacement patterns corresponding 
to cyclic displacements smaller than 200 nanometers can be measured.  The 
findings suggest the feasibility of a medical imaging technique for delineating
elasticity and other mechanical properties of tissue.

 Replicator NN for Universal Coding
Replicator neural networks self-organize by using their inputs as desired 
outputs; they internally form a compressed representation for the input data.
A theorem shows that a class of replicator networks can, through the 
minimization of mean squared reconstruction error (for instance, by training 
raw data examples), carry out optimal data compression for arbitrary data 
vector sources. Data manifolds, a new general model of data limiting case, 
optimal-compression replicator networks operate by creating an essentially 
unique natural coordinate system for the manifold.
