Abstract Silicate glasses are an accepted option for immobilizing nuclear waste and waste glass can be disposed in near-surface environments. It is important to understand glass alteration mechanisms under site-relevant conditions to predict glass corrosion rates upon disposal. Microbial activity near the glass surface may influence glass alteration. However, waste glass chemical durability is currently evaluated without consideration of microbial alteration.

The sun shines on a prairie field. A herd of mustangs grazes peacefully. Suddenly, a helicopter roars over the hill. Horses scatter in every direction. After many miles of running over uneven terrain, the horses are finally caught. Now they may never see each other again. It is imperative that America's wild horses be better protected and managed. This is because the ones removed are not handled well, they improve the land for livestock, and there are better ways to manage population than roundups.
