  We present results from several new searches for physics beyond the Standard
Model. We describe a search based on the scalar sum of the transverse energy of
the event, a global quantity nearly independent of the event topology. We
summarize our searches for first generation leptoquarks into all three decay
channels, eq eq, eq nu q, and nu q nu q, and note that this is the first time
that the triumvirate of decay channels has been searched. We do not find any
evidence for production of first generation leptoquarks and set a lower limit
on the mass of the leptoquark of 175 GeV/c^2, assuming the decay is exclusively
into eq eq. We also present results from the first search for a third
generation leptoquark with charge = +/- 1/3. Again, we find no evidence for its
existence for a mass less than 80 GeV/c^2. Finally, we discuss one of our
searches for supersymmetry, specifically the pair-production of selectrons,
sneutrinos, and chi_2^0 where the decay yields final states with two photons
plus missing transverse energy. We set limits on the production cross section
ranging from 1 pb to 400 fb, depending on the mass. This analysis also sets a
model-independent upper limit on the cross section times branching ratio to two
photons + missing transverse energy + X of 185 fb at the 95% CL for transverse
energy of the photons > 12 GeV with eta < 1.1 and missing transverse energy >
25 GeV.
