In science:

Recent results from the submm balloon experiment PRONAOS (Dupac et al. 2001) find tentative evidence for an inverse dependence of β on T but the result is largely based on one cloud (OMC-1) having a lower β and higher temperature than the others.
The SCUBA Local Universe Galaxy Survey II. 450 micron data - evidence for cold dust in bright IRAS Galaxies
High frequency measurements were also made with the balloon-borne PRONAOS (Lamarre et al. 1998) - the first detection of the S-Z effect from the stratosphere - and ground-based MITO (De Petris et al. 2002) experiments.
The Sunyaev-Zeldovich Effect
The DIABOLO experiment has been used to measure the SZ effect in this cluster at millimetric wavelengths (Desert et al. 1998), and PRONAOS measured the sub-mm SZ effect for the first time in Abell 2163 (Lamarre et al. 1998).
A study of the Sunyaev-Zel'dovich increment using archival SCUBA data
FIR observations of a filament in Taurus by the PRONAOS balloon-borne experiment suggest that at the highest densities, the population of smallest grains disappears and the submillimeter emissivity increases by a factor of about 3, as expected by models of dust coagulation into fluffy grains (Stepnik et al. 2003).
