This is down at the other end of the size spectrum
from cosmology, but that and particle physics seem
to be joined at the hip anyway, and attempts to make
that juncture even stronger are ongoing.

By a truly heroic calculation with a matrix of
10,000,000,000,000 entries, researchers were able to
include virtual quark anti-quark pairs along with
the usual gluons, to sharpen the
from-first-principles prediction of the mass of the
proton and neutron from within 10% of the measured
value to within 2%, and they know that they're not
yet taking the Higgs field into account (since the
mass of the Higgs particle is as yet unknown, I
suppose).

Read as science reporting; I'm sure the technical
report is visible somewhere.
