  We report here our latest search for molecular outflows from young brown
dwarfs and very low-mass stars in nearby star-forming regions. We have observed
three sources in Taurus with the Submillimeter Array and the Combined Array for
Research in Millimeter-wave Astronomy at 230 GHz frequency to search for CO
J=2-1 outflows. We obtain a tentative detection of a redshifted and extended
gas lobe at about 10 arcsec from the source GM Tau, a young brown dwarf in
Taurus with an estimated mass of 73 M_J, which is right below the
hydrogen-burning limit. No blueshifted emission around the brown dwarf position
is detected. The redshifted gas lobe that is elongated in the northeast
direction suggests a possible bipolar outflow from the source with a position
angle of about 36 degrees. Assuming that the redshifted emission is outflow
emission from GM Tau, we then estimate a molecular outflow mass in the range
from 1.9x10^-6 M_Sun to 2.9x10^-5 M_Sun and an outflow mass-loss rate from
2.7x10^-9 M_Sun yr^-1 to 4.1x10^-8 M_Sun yr^-1. These values are comparable to
those we have observed in the young brown dwarf ISO-Oph 102 of 60 M_J in rho
Ophiuchi and the very low-mass star MHO 5 of 90 M_J in Taurus. Our results
suggest that the outflow process in very low-mass objects is episodic with
duration of a few thousand years and the outflow rate of active episodes does
not significantly change for different stages of the formation process of very
low-mass objects. This may provide us with important implications that clarify
the formation process of brown dwarfs.
