I will discuss the Reichardt, et al. 2008 paper with the latest results from the ACBAR Cosmic Microwave Background experiment. Compared to their last release, the new dataset has twice the total integration time, five times the sky coverage, and better calibration leading to an improved determination of the CMB power spectrum at small angular scales.

The Main Injector Neutrino Oscillation Search (MINOS) is a long baseline neutrino oscillation experiment designed to make a precision measurement of delta m**2 (2-3). Cosmic ray muons are a source of background for such an experiment, but they are an isotropic data source with many calibration and scientific uses. MINOS has measured the atmospheric muon charge ratio to very high precision, as well as the seasonal variation in underground muon rate. New models describing both physical effects have been developed, and both are shedding new light on K-pi in cosmic ray airshowers. The shadow of the moon is an important analysis to establish the resolution and absolute pointing capability of a cosmic ray detector, and it can also be used to put limits on the anti-matter content of cosmic ray primaries.

Numerical models of the first primeval galaxies find that they were small, highly irregular structures built up in gravitational mergers between dark matter halos that hosted single massive primordial stars from z ~ 10 - 15. The stars were only marginally enriched by the first heavy elements because supernovae preferentially blew metals out into low density voids where star formation was not possible. Unfortunately, the large computational box sizes of these models prevented them from adequately resolving primordial SN remnants or the mixing and cooling of baryons by metals. I will present new calculations of SN explosions in the first star forming halos that resolve the flows over all relevant spatial scales. They suggest that an entire population of stars may have formed in a single remnant; if so, far more stars populated the first galaxies than now supposed, with lower masses and higher metallicities.
