At least 100 people were killed across Syria today by security forces loyal to President Bashar Assad, activists said. The Local Coordination Committees, which organize protests on the ground and document the killings, said 76 people were killed in the restive central region of Homs.

The past five days have been some of the bloodiest since the uprising began last March, with about 387 people killed since Thursday, activists said.

Grade-schoolers are supposed to be riding in booster seats. But anyone who's ever chauffeured a bunch of second-graders can tell you that the day will come when you don't have enough boosters to go around. Faced with this obvious safety risk, most parents (including this one) buckle up the kids without boosters, and pray.

One of the biggest antitrust investigations in the nation's history has led to fines of $470 million against one Japanese auto parts manufacturer and $78 million against another, the U.S. Justice Department announced today.

The contest for the seat held by Sen. Jon Tester, a Montana Democrat, is one of the potentially close 2012 races that could ultimately decide whether Democrats maintain control of Congress' upper chamber.

As such, the battle is attracting attention from outside groups hoping their financial assistance will make a difference for both the first-term Democrat and his Republican challenger, Rep. Denny Rehberg, the state's sole House member and a former lieutenant governor.

The FBI has raised eyebrows in the tech world with a public document that asks for advice on how to harvest information from social networking sites.

Republican presidential hopeful Rick Santorum was back on the campaign trail Monday after improvements in the medical condition of his hospitalized young daughter Isabella or "Bella."

Bella's pneumonia, linked to a severe genetic condition, forced the former U.S. senator from Pennsylvania to cancel campaign events in Florida over the weekend.

But with the three-year old's turn for the better, Santorum headed to the Midwest to resume campaigning, forgetting Florida where Mitt Romney appeared headed for a big win Tuesday.

One of the guests in the congressional gallery at last week's State of the Union address was Roxana Delgado, an advocate for soldiers returning home with traumatic brain injuries. Her husband, an army sergeant who NPR profiled in June, 2010, had been dramatically affected by the concussion he received from a roadside blast in Iraq.

Many investors are expecting Facebook to file papers for an initial public offering sometime later this week. The company, which was founded in a Harvard dorm room less than a decade ago, is expected to be valued at nearly $100 billion by Wall Street.

And if these early reports are true this is shaping up to be the biggest Internet IPO ever.

Thousands marched in Spain on Sunday in support of Baltasar Garzon, the Spanish judge who became an icon for human-rights activists when he indicted former Chilean dictator Augusto Pinochet in 1998.

Now, Spain's most famous judge is on trial, after turning his investigations toward the country's own fascist past.

Garzon, 56, is a champion of universal jurisdiction — the idea that the most heinous crimes need to be prosecuted, no matter where or when.

Republican presidential hopeful Newt Gingrich is changing another of his positions in an effort to woo socially conservative voters.

Over the weekend he told churchgoers in Florida that as president he'd work to ban research using stem cells derived from human embryos.

Gingrich has long been a strong backer of federal funding for scientific research. In 2001 his support extended to research on stem cells derived from human embryos left over from in vitro fertilization efforts.

But apparently that's no longer the case.
