Branching fractions and direct CP asymmetries of charmless decay modes at the Tevatron
We present new CDF results on the branching fractions and time-integrated
direct CP asymmetries for and decay modes into pairs of
charmless charged hadrons (pion or kaon). The data set for this update amounts
to 1 fb of collisions at . We report
the first observation of the mode and a
measurement of its branching fraction and direct CP asymmetry. We also observe
for the first time two charmless decays of -baryon: and .Comment: Proceedings for Beauty 2006, Sept. 25-29 at Oxford University, to be

Updated measurements of hadronic B decays at CDF
The CDF experiment at the Tevatron collider established that
extensive and detailed exploration of the --quark dynamics is possible in
hadron collisions, with results competitive and supplementary to those from
colliders. This provides a rich, and highly rewarding program that has
currently reached full maturity. In the following I report some recent results
on hadronic decays: the evidence for the charmless annihilation decay mode
, and the first reconstruction in hadron collisions of the
suppressed decays and .Comment: 5 pages,2 figures, proceedings for EPS-HEP 2011. To be published in

CP and charge asymmetries at CDF
We present CDF results on the branching fractions and time-integrated direct
CP asymmetries for B0 and B0s decay modes into pairs of charmless charged
hadrons (pions or kaons). We report also the first observation of B0s->DsK mode
and the measurement of its branching fraction.Comment: Proceedings of The 2007 Europhysics Conference on High Energy Physics

This report looks at the distribution of air toxics, respiratory hazard, and school children in the state of California. The report finds evidence of disproportionate exposure and a potential link between such exposure and school-level academic performance, and calls for policy changes that can better situate environmental health concerns within initiatives for school improvement
Still Toxic After All These Years: Air Quality and Environmental Justice in the San Francisco Bay Area
From West Oakland's diesel-choked neighborhoods to San Francisco's traffic-snarled Mission District to the fenceline communitis abutting Richmond's refineries, poor and minority residents of the San Francisco Bay Area get more than their share of exposure to air pollution and environmental hazards. That's the conclusion of a new report issued by the Center for Justice, Tolerance & Community (CJTC) at the University of California, Santa Cruz. The first published analysis of the overall state of environmental disparity in the nine-county region, the report is entitled, "Still Toxic After All These Years... Air Quality and Environmental Justice in the Bay Area.
Minding The Climate Gap: What's at Stake if California's Climate Law isn't Done Right and Right Away
Minding the Climate Gap: What's at Stake if California's Climate Law isn't Done Right and Right Away details how incentivizing the reduction of greenhouse gases -- which cause climate change -- from facilities operating in the most polluted neighborhoods could generate major public health benefits. The study also details how revenues generated from charging polluters could be used to improve air quality and create jobs in the neighborhoods that suffer from the dirtiest air. In California, children in poverty, together with all people in poverty, live disproportionately near large facilities emitting toxic air pollution and greenhouse gases.People of color in the state experience over seventy percent more of the dangerous pollution coming from major greenhouse gas polluters as whites, and the disparity is particularly sharp for African Americans. The racial differential in proximity to pollution is not just a function of income: people of color are more likely to live near these polluting facilities than whites with similar incomes. Continuing to move forward with California's climate law presents the opportunity to save lives and bolster California's economy by focusing pollution reductions in neighborhoods suffering the worst public health impacts
