The latest bad news in the hunt for an AIDS vaccine: The government halted a large U.S. study on Thursday, saying the experimental shots are not preventing HIV infection.

Nor did the shots reduce the amount of the AIDS virus in the blood when people who'd been vaccinated later became infected, the National Institutes of Health said.

Bayern Munich has denied a report that Borussia Dortmund forward Robert Lewandowski has signed a contract with the Bundesliga champions.

Bayern issued the denial Friday after the mass-circulation Bild daily reported, without citing sources, that the Poland striker had already signed two contracts with Bayern — one starting in 2013 and one in 2014.

The ageless Ray Allen scored 23 points, and broke the NBA career playoff record for 3-pointers, as the Miami Heat used another of their patented runs to win 104-91 at the Milwaukee Bucks on Thursday for a 3-0 lead in their first-round series.

In the day's other playoff games, the Chicago Bulls held off Brooklyn to take a 2-1 lead, while Memphis got the win it needed, beating the Los Angeles Clippers to cut the series deficit to 2-1.

David Luiz scored with the final kick of the match to clinch a 2-1 win for Chelsea at Basel in a Europa League semifinal, first leg on Thursday.

Luiz deceived goalkeeper Yann Sommer with a free kick in the fourth minute of stoppage time after Basel defender Fabian Schaer had equalized with a disputed 87th-minute penalty.

Bidders looking for a pair of mended underwear worn by a former emperor came away disappointed Thursday from an auction of Austrian imperial memorabilia. But a lock of his hair was on offer, and went under the hammer for nearly 14,000 euros (around $18,000) —more than 20 times its listed worth.

Vienna's prestigious Dorotheum auction house had said Emperor Franz-Josef's linen would be put on the block, suggesting there was a least a chance that one of the parsimonious ruler's patched undergarments would be put on sale.

MTV is getting ready to blast viewers with a brand-new "Scream."

The network says it will produce a pilot for a TV-series adaptation of the wildly popular slasher films. The series would reinvent the horror-comedy franchise that began with the original release in 1996 and spawned three sequels, the most recent in 2011.

Reggaeton star Don Omar was the top winner of the Billboard Latin Music Awards, though the bigger star of the show might have been the one who wasn't there: The late Mexican-American singer Jenni Rivera.

Don Omar took home 10 prizes at the annual show Thursday honoring Spanish-language songs and performers. Rivera won six prizes, including artist of the year. The California-born superstar was killed in a plane accident last year in Mexico.

A 16th-century Amati violoncello displayed in the National Music Museum has long been nicknamed "The King," but the ghost of a legendary rock 'n' roller has arrived in South Dakota to reclaim his regal moniker.

A slightly smashed acoustic guitar played by Elvis Presley on his final tour in 1977 now greets visitors in front of the museum's main galleries. The Martin D-35 was tossed aside by "The King" during a St. Petersburg, Fla., concert after suffering a broken strap and string, said Robert Johnson, a Memphis-based guitarist who donated the item.

Not so long ago, there was a certain image associated with being vegetarian. It usually involved Birkenstock sandals, lentil loaf and an agenda.

There still are plenty of all three in the meatless movement, but a growing number of Americans are finding they can have cauliflower and kale at the center of the plate without a side of ideology.

A school close to London's busy Heathrow Airport has found a novel way to protect its young students from the relentless roar of planes taking off and landing nearby.

The school has installed a series of sound-cancelling adobe domes outdoors so that its students, ages 3 to 7, can enjoy playtime and lessons outside without fearing damage to their ears.
