  Many early-type galaxies are detected at 24 to 160 micron but the emission is
usually dominated by an AGN or heating from the evolved stellar population.
Here we present MIPS observations of a sample of elliptical and lenticular
galaxies which are rich in cold molecular gas, and we investigate how much of
the MIR to FIR emission could be due to star formation activity. The 24 micron
images show a rich variety of structures, including nuclear point sources,
rings, disks, and smooth extended emission, and comparisons to
matched-resolution CO and radio continuum images suggest that the bulk of the
24 micron emission can be traced to star formation. The star formation
efficiencies are comparable to those found in normal spirals. Some future
directions for progress are also mentioned.
