    12 We report on recent progress and future prospects in three broad areas
    13 of research centered around the formation of low-mass stars and brown
    14 dwarfs. First, we discuss efforts to directly and accurately measure
    15 the fundamental physical properties (masses, radii, luminosities)
    16 of young low-mass stars and brown dwarfs as critical tests of
    17 theoretical star-formation models, including the recent discovery of
    18 the first brown-dwarf eclipsing binary. Second, we discuss the broad
    19 problem of magnetic field generation and X-ray production in these
    20 objects, highlighting results from the recent Chandra Orion Ultradeep
    21 Project. Third, we briefly discuss the problem of angular momentum
    22 evolution in these objects (i.e., the "angular momentum conundrum"
    23 of star formation), highlighting results from recent large surveys
    24 of stellar rotation in young clusters. Finally, we draw these recent
    25 results together to elucidate the physical interrelationships between
    26 stellar rotation, magnetic field generation, and stellar structure
    27 during the star-formation process.
