Until recently, very few people had ever heard of raspberry ketones, the aromatic compounds that give the berries their distinctive smell. Today, health food stores have trouble keeping the capsules or drops of the stuff on their shelves. Almost overnight, an obscure plant compound became the next big thing in weight loss - and all it took was a few words from Dr. Oz. In a February episode of "The Dr. Oz Show," Mehmet Oz told viewers that raspberry ketones were "the No. 1 miracle in a bottle to burn your fat. " Once Oz calls something a "miracle," it doesn't remain obscure for long.

Investigators don't know where 15-year-old Sierra LaMar is, but they are almost certain she is dead. For more than two months, the high school cheerleader's family has been holding out hope. They have organized repeated searches of the Northern California neighborhood where she disappeared and made numerous public appeals for help. On Tuesday, even as authorities announced the arrest of a 21-year-old suspect on suspicion of murder, Marlene LaMar vowed not to stop looking for her daughter.

WASHINGTON - Hall of Fame quarterback Joe Montana said they improved his strength and posture. Celebrity Kim Kardashian boasted they allowed her to ditch her personal trainer. But federal and state officials said the rocker-bottom Shape-ups and other toning shoes made by Skechers USA Inc. don't live up to the hype from the company and its high-profile endorsers. On Wednesday, the Manhattan Beach company agreed to pay $50 million to settle false-advertising allegations by the Federal Trade Commission and the attorneys general of 44 states, including California, as well as the District of Columbia.

WASHINGTON - The prostitution scandal that has embroiled the Secret Service is not evidence of a wider culture of boozing and paying for sex among those who are trained to take a bullet for the president, the director of the agency told skeptical senators. The senators challenged Secret Service Director Mark Sullivan to explain how it was possible, without an atmosphere of permissiveness among the agency's supervisors, that 12 agents could go out in separate groups on April 11 in Cartagena, Colombia, independently decide to bring women back to their hotel rooms, and then sign the women in at the front desk next to the agents' real names.

Manny Hamelburg, 68, a retired businessman, had fought prostate cancer for years. First, he tried radiation, then a drug with side effects that nearly killed him, and finally Lupron, a drug that blocks production of testosterone, the hormone that can fuel prostate cancer. The cancer disappeared. But life was miserable. Without normal levels of testosterone, Hamelburg says, he had no energy, and "zero libido for seven years. I was like a eunuch. I was chemically castrated. Sex was just hugs."

washington -- Mitt Romney twice emphasized his unique business background when he and eight other Republican presidential candidates faced off in a debate last week in Iowa. "I've spent the last, as I've told you, 25 years in the private sector," former Massachusetts Gov. Romney declared at one point. "I understand why jobs come and why jobs go. I've done business in 20 countries."

The PSA test should be abandoned as a prostate cancer screening tool, a government advisory panel has concluded after determining that the side effects from needless biopsies and treatments hurt many more men than are potentially helped by early detection of cancers. At best, one life will be saved for every 1,000 men screened over a 10-year period, according to the U.S. Preventive Services Task Force. But 100 to 120 men will have suspicious results when there is no cancer, triggering biopsies that can carry complications such as pain, fever, bleeding, infection and hospitalization.

A federal administrative judge ruled that pomegranate juice maker Pom Wonderful used deceptive advertising when it implied its products could treat or prevent serious diseases and other medical conditions. Judge D. Michael Chappell upheld much of a 2010 Federal Trade Commission complaint against the Los Angeles company owned by Lynda and Stewart Resnick. The judge said in his decision issued Monday that Pom used "insufficient" evidence to back its claims that Pom products "treat, prevent or reduce the risk of heart disease, prostate cancer or erectile dysfunction.

"Oh, you mean the guy with the 70-year-old head and the 20-year-old body-builder body? That picture has got to be Photoshopped." Dr. Jeffry Life smiles when I tell him about the general reaction I get about the famous picture of him with his shirt off, the shot that turned a mild-mannered doctor in his mid-60s into a poster boy for super-fit aging and controversial hormone replacement Appearing in medical-clinic ads in airline magazines and...

Los Angeles police will not pursue through the courts scores of motorists with unpaid tickets from the city's defunct red-light camera program. The city Police Commission voted this week to end its contract with the company that operated L.A.'s cameras until they were shut off last summer. And authorities are now planning to reassign a small group of officers who regularly appeared in court to testify in contested photo enforcement cases. With the cancellation of the contract, officers will no longer have easy access to the photo and video evidence that courts require.

GREENSBORO, N.C. - The jurors who will decide the fate of former presidential candidate John Edwards deliberated for more than four hours Friday before breaking for the weekend in a trial focused on complex campaign finance laws and lurid details of Edwards' extramarital affair. The jury of eight men and four women must decide whether Edwards knowingly conspired to violate federal election laws as part of a scheme to cover up his affair with videographer Rielle Hunter during his campaign for the 2008 Democratic presidential nomination.

WASHINGTON — An anxious wife drove Brian McNamee to hold on to evidence of Roger Clemens' steroid use for self-protection, the former trainer testified at the former pitcher's federal perjury trial. "She kept saying in the midst of a battle royale, 'You're going to go down if something ever happens,' " McNamee said. So as a measure of insurance, McNamee said, he held on to a beer can filled with a used needle, a syringe and a glass steroid ampule he had fished out of Clemens' recycling bin in 2001.

On May 1, Gavin Smith disappeared. After returning from a Las Vegas conference, the longtime 20th Century Fox executive -- who distributed such hits as "Titanic" and "Avatar" -- inexplicably missed a school pickup for his teenage son. His Mercedes is missing along with him. His family and authorities have been unable to locate him either through cellphone records or credit card billings. This week, the Los Angeles County Sheriff's Department intensified its search, but detectives said they have no solid leads.

In August, NASA's Mars Science Laboratory will reach the Red Planet and begin its search for habitats that could have supported life. The next-generation rover, better known by the nickname Curiosity, will pick its way up a mound in the middle of Gale crater and look for evidence that water once flowed on the Martian surface - a condition that is considered a prerequisite for hosting microbial beings. On an expedition to the California desert this month to demonstrate some of the challenges Curiosity will face on Mars, scientists chatted about the upcoming mission.

The European elections have concluded and the results are clear: Voters in France and Greece are a lot smarter than economic policymakers in the United States. Or at least they're a lot more attuned to the folly of relying on austerity as a tool of economic growth. If you've missed the weekend's headlines, French voters elected their first Socialist president since Francois Mitterand left office in 1995. The new president, Francois Hollande, won after promising to loosen the reins of economic austerity and impose more sacrifices on the rich.

On summer nights in the mid-1960s, while black-and-white television crackled elsewhere in his Staten Island home with news of Southern violence and Vietnam, Bobby Lasnik would stretch out in his bedroom to let the righteous soundtrack of the civil rights movement waft into his impressionable teenage soul. Tuned in to WBAI-FM, coming across the water from Manhattan, he heard baleful laments about injustice that he would carry with him for a lifetime. "Suddenly there was someone speaking a certain kind of truth to you. You'd say, 'Wow!

A new study showing an estimated 7% of American teens and adults carry the human papillomavirus in their mouths may help health experts finally understand why rates of mouth and throat cancer have been climbing for nearly 25 years. The evidence makes it clear that oral sex practices play a key role in transmission. The new data, published online Thursday by the Journal of the American Medical Assn., are the first to assess the prevalence of oral HPV infection in the U.S. population.

DALLAS - On the way to witness his first execution in the town known as the "Execution Capital of the World," the Dallas County district attorney stopped at the prison cemetery to find his great-grandfather's grave. Captain Joe Byrd Cemetery in Huntsville is the final resting place of inmates whose families could not afford burial anywhere else. Tall pines guard the grassy expanse nicknamed "Peckerwood Hill," where many gravestones bear prison identification numbers, not names.
