Democrats lost no time in attacking the budget plan House Republicans introduced Tuesday. The plan saves money by overhauling Medicare, but Democrats argue it will destroy the program.

One of the Democrats leading the charge is Vice President Joe Biden. Taking on the role of candidate, Biden was in Coconut Creek, Fla., giving the second in what he promises will be a series of campaign speeches challenging the Republicans.

Students walked out of more than 30 Miami schools on Friday, some chanting "Justice for Trayvon," in a sign of solidarity with the 17-year-old black student who was killed by a neighborhood watch volunteer last month in Sanford, Fla.

Protesters numbered more than 1,000 at some schools, others fewer than 100. Some teachers and principals gave their tacit approval.

The first walkout was at Carol City High School, where Trayvon Martin was a student last year. Hundreds of his old schoolmates walked out in the middle of the school day.

A discarded chunk of a Russian rocket forced six space station astronauts to seek shelter in escape capsules early Saturday, then ultimately safely passed in front of the space station, according to NASA.

NASA spokesman Rob Navias told The Associated Press ahead of the incident that the space junk would barely be close enough to be a threat.

Former New Jersey Gov. Jon S. Corzine directly ordered that $200 million from a segregated customer account be transfered to cover a $175 million overdraft in a London account.

Jim Yong Kim, President Obama's nominee to be the leader of the World Bank, is an unconventional choice. As a global health expert, he's a medical doctor who helped start an international health organization. He currently serves as president of Dartmouth College.

"Despite its name, the World Bank is more than just a bank," Obama told reporters during the White House announcement Friday morning. "It's time for a development professional to lead the world's largest development agency."

Across the country, thousands of people skipped lunch Friday to protest what they see as a threat to religious liberties in the United States.

The protesters' specific complaint was the birth control mandate in the new health care law, but the discontent runs far deeper.

It didn't take much for the Rev. Pat Mahoney, an evangelical minister, to warm up the crowd in Washington. He gazed out at hundreds of people who filled the plaza in front of Kathleen Sebelius' office at the Department of Health and Human Services.

An independent review of the federal Mine Safety and Health Administration's (MSHA) enforcement at the Upper Big Branch (UBB) coal mine in West Virginia says the agency failed to spot "a number of enforcement deficiencies" at the mine which were major factors in the April 2010 explosion that took 29 lives.

We've known for a while that people who grow up on farms are less likely to have ailments related to the immune system than people who grow up in cities. Those include asthma, allergies, inflammatory bowel disease and multiple sclerosis.

If Danish pigs can live with fewer antibiotics, why can't their American cousins?

It's a hot topic, especially today. Yesterday, a federal judge ordered the U.S. Food and Drug Administration to proceed with a 1977 plan to outlaw the use of certain antibiotics as growth promotion drugs.

Asians are the fastest growing racial group according to a recent report released by the U.S. Census Bureau analyzing 2000 and 2010 census figures.

For those following the nation's changing demographics that may sound surprising because we've also been hearing that Hispanics are the "fastest growing minority group."
