Activity cuts the risk of Alzheimer's disease and slows cognitive decline, even in the very old, according to a new study.
There's been plenty of evidence for the "use it or lose it" theory of brain capacity. But this study is one of the first to show that activity of all sorts benefits people over age 80, even if they're not "exercising."
The DREAM Act calls for a path to citizenship for some undocumented students. In the past, Republicans have opposed versions of the bill, but some prominent figures like former U.S. Attorney General Alberto Gonzales say the GOP needs to find its own voice on the issue.

Ban says the government has failed to keep its pledge to withdraw troops and heavy weapons from cities, but adds that he still thinks there is "opportunity for progress."

Proponents of the death penalty often argue that the threat of being executed acts as a deterrent that prevents people from committing murder. But those who oppose capital punishment challenge that claim. And some researchers argue that state-sanctioned execution might actually increase homicide rates.
Now, a panel of independent experts convened by the prestigious National Research Council has taken a look at this question and decided that the available research offers no useful information for policymakers.
The Environmental Protection Agency's new air pollution rules for the oil and gas industry may seem like odd timing, as President Obama has been trying to deflect Republican criticism that he overregulates energy industries. But the rules weren't the Obama administration's idea.
Several years ago, communities in Colorado, New Mexico and Wyoming complained about air pollution from natural gas booms in their local areas.
