The Rock and Roll Hall of Fame and Museum opened its new library and archives to the public on Tuesday to give scholars and fans access to the stories behind the music through such "artifacts" as personal letters from Madonna and Aretha Franklin and 1981-82 video of the Rolling Stones tour.

The collection, catalogued over the last few years, includes more than 3,500 books, 1,400 audio recordings and 270 videos, and is housed in the new four-story, $12 million building.

An anti-profanity crusader has asked the ABC television network to pull this week's "Modern Family" episode in which a toddler appears to use a bleeped curse word.

"Our main goal is to stop this from happening," McKay Hatch, an 18-year-old college student who founded the No Cussing Club in 2007, said Tuesday. "If we don't, at least ABC knows that people all over the world don't want to have a 2-year-old saying the 'F-bomb' on TV."

Scientists studying white nose syndrome in bats estimate the fungal ailment has killed at least 5.7 million bats in 16 states and Canada, providing alarming new numbers about the scope of its decimation.

White nose is caused by a fungus that prompts bats to wake from their winter hibernation and die after they fly into the cold air in a doomed search for insects. First detected in a cave west of Albany in 2006, white nose has spread to 16 states from the Northeast to the South and as far west as Kentucky. It also has been detected in four Canadian provinces.

The stock market will rally strongly in the second half of 2012, much like a dragon rising from the depths, according to a Hong Kong brokerage's annual astrological predictions.

Defending champion Kim Clijsters and No. 1-ranked Caroline Wozniacki advanced to the third round of the Australian Open in contrasting styles on Wednesday.

Clijsters needed only 47 minutes to beat Stephanie Foretz Gacon of France 6-0, 6-1, then showed just how much support she has at Rod Laver Arena by getting the crowd to sing 'Happy Birthday' to her younger sister.

Nearly eighteen years after the death of three-time world champion Ayrton Senna in a high-speed crash, the Senna name is returning to Williams Formula One team.

Senna's 28-year-old nephew, Bruno, signed a one-year deal to partner Venezuelan driver Pastor Maldonado and give the British team an all-South American lineup going into the March 18 opener in Australia.

America's obesity epidemic is proving to be as stubborn as those maddening love handles, and shows no sign of reversing course. More than one-third of adults and almost 17 percent of children were obese in 2009-2010, echoing results since 2003, the Centers for Disease Control and Prevention reported Tuesday.

"It's good that we didn't see increases. On the other hand, we didn't see any decreases in any group," said CDC researcher Cynthia Ogden.

Jose Mourinho defended Cristiano Ronaldo's form on the eve of Real Madrid's Copa del Rey quarterfinal against Barcelona, describing his performance against Mallorca as his best since the coach's arrival at the club.

Ronaldo has come under criticism after squandering chances in a 3-1 loss to Barcelona last month, but Mourinho said the forward's work ethic in the second half of Saturday's 2-1 win was better than all of his Madrid accomplishments before.

A motorized, seat-less unicycle, a video game you control with your eyes, and a mind-reading headset that serves as a game controller were among the more bizarre gadgets being shown off at this year's International Consumer Electronics Show.

Some 3,100 exhibitors attended the show, and although there were plenty of mainstream technologies on display, the show attracted a fair share of off-beat gadgets. Here's a roundup of some of the weirdest devices:
