DESCRIPTION:The current generation of new physics searches at the LHC has 
 come up empty.  New tools and techniques are necessary to design the next 
 generation to be even more sensitive to deviations from the Standard Model
  expectations.  Two paths to that goal are described.  The discrimination 
 of quark-initiated jets from gluon-initiated jets\, which could provide su
 bstantial background rejection for some new physics processes\, is demonst
 rated for the first time using data to derive jet properties.  First searc
 h results are also shown for an ATLAS search with event-level variables th
 at may provide the other key to discovering or excluding supersymmetry at 
 the LHC.
