Our observations of the quiet Sun with the NST have yielded unanticipated results on small-scale solar dynamics. Although small-scale solar dynamics have been well-studied, the NST is enabling us to probe finer scale dynamics exploiting higher spatial resolution. We discuss NST results from data taken 29th July 2009 using a broadband filter centered on the TiO 705.7nm spectral line. Data are from the center of the solar disk and at the north and west limbs, where we observed quiet Sun. We registered bright-point like structures in most of the intergranular lanes. They vary in behavior and evolution. Co-registered solar oscillations tend to congregate near certain types of bright-point like structures, while around others they appear with the same distribution as in the parts of the granular field devoid of the bright-point like structures. The origins and implications of these curious results will be discussed.
