  We show Akari data, Herschel data and data from the SCUBA2 camera on JCMT, of
molecular clouds. We focus on pre-stellar cores within the clouds. We present
Akari data of the L1147-1157 ring in Cepheus and show how the data indicate
that the cores are being externally heated. We present SCUBA2 and Herschel data
of the Ophiuchus region and show how the environment is also affecting core
evolution in this region. We discuss the effects of the magnetic field in the
Lupus I region, and how this lends support to a model for the formation and
evolution of cores in filamentary molecular clouds.
