As investigators look into the Boston Marathon bombings, one crucial question is whether the suspects, brothers Tamerlan and Dzhokhar Tsarnaev, acted alone or had help. The clues might be found in the bombs used.

From what is now known, it appears the brothers assembled a whole arsenal of explosives. Watertown Police Chief Edward Deveau told CNN last weekend that the suspects had at least six bombs, including the two used in the attack and one thrown at police during a shootout.

More online retailers would have to collect sales tax under a bill making its way through the U.S. Senate this week. The measure won strong bipartisan backing on a procedural vote Monday, and President Obama has said he would sign it.

When Cheeseburger = Walking, Will We Eat Less?

Would you like that burger with a side of exercise?

Nutrition labeling has been required on packaged food since 1990, and the new federal food safety law will require calorie counts to be posted for restaurant food — all in an effort to get the American public to eat healthier.

But most studies on calorie count labels show they don't do much to nudge people toward better food choices. If I want that oh-so-delicious Chunky Monkey ice cream, knowing that a half-cup serving delivers 300 calories and 18 grams of fat isn't going to stop me.

Footage from surveillance cameras along the Boston Marathon route gave the FBI early clues about the bombing suspects. And prosecutors say they'll use some of those images to try to prove their criminal case against 19-year-old Dzhokhar Tsarnaev. But the proliferation of cameras in America's big cities is raising some tricky questions about the balance between security and privacy.

It was pictures of two brothers taken by a camera outside the Lord & Taylor department store that provided the first glimpse of the men who allegedly bombed the Boston Marathon.
