When Grammy Awards producers learned of Whitney Houston's death less than 24 hours before the live telecast, they scrapped parts of the script, added performances and puzzled over how best to honor the Grammy-winning singer who died unexpectedly at age 48.

Host LL Cool J said that addressing the Grammy audience at the Staples Center after Houston's death was "definitely the most challenging moment I've faced in my career."

Five years after being treated for breast cancer, "Good Morning America" co-host Robin Roberts has a new health fight on her hands.

NetJets, which sells partial ownership interests in business jets, said Monday that it plans to spend up to $9.6 billion on as many as 425 new planes from Cessna and Bombardier.

A team of Japanese astronomers using telescopes on Hawaii say they've seen the oldest galaxy, a discovery that's competing with other "earliest galaxy" claims.

Finally, some good news for older fathers. A new study hints that their children and even their grandchildren may get a health benefit because of their older age.

A new pan-Arab TV station that went on the air Monday courts viewers who see mainstream coverage of the political upheaval sweeping the Middle East as biased against the regimes in Syria and Iran and their close ally in Lebanon, the powerful Shiite militant group Hizbullah.

The Beirut-based station Al-Mayadeen, Arabic for The Squares, hopes to counter the influence of regional media heavyweights like Al-Jazeera and Al-Arabiya, both funded by oil-rich Sunni Gulf Arab countries that have backed the uprising against Syrian President Bashar Assad. It also promises to support the Palestinian cause and all forms of "resistance" — a term in Mideast parlance usually used to describe Hizbullah and other groups that fight Israel.

Rain or shine, clay or mud, Sunday or Monday, Rafael Nadal rules Roland Garros.

A NASA spacecraft orbiting Mars is in safe mode after it detected a problem.

Players from European clubs have long complained about midweek trips to the extremes of the continent for a Champions League game and then a return home for weekend action but such air miles and hours pale into insignificance compared with those being clocked up by the national teams of Asia.

As the final round of qualification for the 2014 World Cup kicks off, there are three games in nine days for some of the 10 nations still in contention for spots in Brazil. With the Asian Football Confederation (AFC) spanning over 9,000 miles (14,480 kilometers), acclimatization techniques can become just as important as tactics.
