When roasted at 475 degrees, coffee beans are sometimes described as rich and full-bodied. But for the full-bodied person who is not so rich, unroasted coffee beans - green as the day they were picked - may hold the key to cheap and effective weight loss, new research suggests. In a study presented Tuesday at the American Chemical Society's spring national meeting in San Diego, 16 overweight young adults took, by turns, a low dose of green coffee bean extract, a high dose of the supplement, and a placebo.

Scientists dissecting the remains of the disastrous 1980 explosion of Mt. St. Helens in Washington state say that crystal formations trapped in volcanic rocks hold important clues about when a magma-loaded mountain is about to blow - a discovery that could help volcanologists make more accurate predictions about future eruptions. The findings, published in Friday's edition of the journal Science, link the movement of underground magma to earthquakes, gas emissions and other warning signs that are more accessible to experts who monitor active volcanoes above ground.

In an age of long commutes, late sports practices, endless workdays and 24/7 television programming, the image of Mom hanging up her dish towel at 7 p.m. and declaring "the kitchen is closed" seems a quaint relic of an earlier era. It also harks back to a thinner America. And that may be no coincidence. A new study, conducted on mice, hints at an unexpected contributor to the nation's epidemic of obesity - and, if later human studies bear it out, a possible way to have our cake and eat it too, with less risk of weight gain and the diseases that come with it. Just eat your cake - or better yet, an apple - earlier.

Is the routine PSA test to screen for prostate cancer going to fade away now that the U.S. Preventive Services Task Force has recommended against it for men of all ages? The signs are maybe not, according to a survey of primary care physicians done by Dr. Craig E. Pollack and colleagues at Johns Hopkins University School of Medicine. The survey was done in November, after the task force's draft recommendations had been released but before the final ones were published earlier this week in the Annals of Internal Medicine . In the survey, 125 primary care physicians and nurse practitioners affiliated with Johns Hopkins responded to a questionnaire about their approach to PSA screening.

PHOENIX — Andre Ethier said Tuesday he does not plan to impose a deadline on negotiations on the contract extension that could keep him out of free agency. Dodgers General Manager Ned Colletti has said he would like to re-sign Ethier and has discussed the idea with Dodgers President Stan Kasten , who took office three weeks ago. Ethier said Tuesday he and his agent have not received a formal contract proposal from the Dodgers. Ethier also said he did not anticipate a point where free agency could be so close that he would put any contract talks on hold before he could test the market.

First of three parts Tiffany Lee wanted a car. She was weary of the two-hour bus ride to her job at a UCLA Health System clinic. She hated having to ask friends to drive her 7-year-old son to his asthma treatments. But as a single mother with three children, bad credit and a $27,000-a-year salary, she couldn't find a bank or dealership willing to give her a loan. Then a friend steered her to Repossess Auto Sales in Hawthorne. Another buyer might have balked at the deal she was offered.

CINCINNATI - The Rev. Chris Beard is a theological conservative, make no mistake about it. He believes the Bible is the word of God. He believes the Holy Spirit speaks to him directly. He believes, as an article of faith, that abortion and same-sex marriage are wrong. Still, when a group of religious leaders in Ohio held two days of meetings in Cincinnati recently to talk about economic and racial justice, issues usually associated with the political left, there was Beard, a fourth-generation Pentecostal preacher with a disarming smile, a shaved head and a set of convictions that knock holes in the stereotypes about white evangelical Protestants.

Brian Price, once a wrecking ball on UCLA's defensive line, has beaten long odds to return to the NFL after two off-season surgeries aimed at keeping his hamstrings attached to his pelvis, rather than breaking loose and coiling down the backs of his thighs. For Price, who will start at defensive tackle Sunday for the Tampa Bay Buccaneers, his excruciating recovery was a 10-step process. Meaning just two months ago, he could run only 10 steps. "You have these doubts in your head at times," said Price, a second-round pick of the Buccaneers in 2010 who, because of his congenitally malformed pelvis, spent the last half of his rookie season on injured reserve.

Bob Brickman spent months fighting a ticket he got last fall from a red-light traffic camera at Wilshire and Sepulveda boulevards in West Los Angeles. The 61-year-old from Playa Vista eventually decided to give up the fight and fork over the $476 fine. Now he's regretting paying every penny. City officials this week spotlighted a surprising revelation involving red-light camera tickets: Authorities cannot force violators who simply don't respond to pay them. For a variety of reasons, including the way the law was written, Los Angeles officials say the fines for ticketed motorists are essentially "voluntary" and there are virtually no tangible consequences for those who refuse to pay. The disclosure comes as the city is considering whether to drop the controversial photo enforcement program, with the City Council scheduled to vote on the matter Wednesday.

Watching Alzheimer's disease steal away the memory, talents and very selves of its victims is hard enough for the people who love them. Now, a new pill formulated by a respected pharmaceutical company and approved by the Food and Drug Administration will do little to help most patients and will bring misery to some, say two medical investigators. The drug, Aricept 23 mg, is no more effective on the whole than the disappointing ones already on the market - but is more likely to cause gastrointestinal problems, wrote Drs. Steven Woloshin and Lisa Schwartz of Dartmouth Medical College in an article published Thursday in the medical journal BMJ. The new formulation was devised to serve commercial objectives, they say, and was approved despite a poor showing in company-sponsored tests.

New home sales are up. The unemployment rate is falling. Companies are buying one another, signaling confidence in the economy. But investors are turning their back on positive economic signs, looking nervously at Europe's seemingly never-ending debt troubles and Facebook's flat IPO, wondering whether the global economy is beginning yet another deep dive. "Although better economic data did not go unnoticed, investors look forward and not backward," said David Dietze, president and chief investment strategist at Point View Wealth Management in Summit, N.J. "All eyes are looking across the pond and seeing a bit of a meltdown in terms of the European sovereign debt crisis.

Beverly Hills-based RealD Inc. is further expanding its presence in China. The 3-D equipment supplier said Wednesday it had a signed a deal to install 100 3-D screens for the Bona Film Group's theater circuit in China.  Bona, a leading film distributor in China, plans to install RealD 3-D systems at each of the company's 11 theater locations. "3-D technology gives moviegoers a more immersive visual experience, which takes the movie business to a new level," said Don Yu, chairman and CEO of Bona Film Group.

Monday was a busy day for the Tampa Bay Buccaneers on the tight end front.First they traded former all-pro Kellen Winslow to the Seattle Seahawks for an undisclosed conditional draft pick in 2013. Then they signed another ex-pro bowler in free agent Dallas Clark, formerly of the Indianapolis Colts.Last season Winslow led the Bucs in receptions (75) and was a very close second in receiving yards to Mike Williams (771 to 763).

The battle for the soul of Dodger Stadium is about to be joined. It is a battle for your eyes, for your ears, for your wallets. It is a battle over what it means to attend a baseball game in the new millennium. It is a battle sanitized by jargon: This is about the "fan experience. " The Dodgers' new owners all but canonizedPeter O'Malley during their introductory news conference, so this would be a good time to recall that O'Malley did not employ mission statements or talking points or the term "fan experience.

SACRAMENTO - For years, running for office as a Republican in California boiled down to one core pledge, bound by a candidate's signature and enforced with a vengeance: no new taxes. Not anymore. The state's new political landscape, scrambled by freshly drawn voting districts and new election rules, has given rise to a handful of GOP hopefuls proudly bucking the anti-tax orthodoxy. Their candidacies have the potential to end years of partisan gridlock here. It would have been unimaginable in the last election, just two years ago: At least five viable Republican contenders for the Assembly are refusing to sign the no-tax pledge that helped ensure protracted budget negotiations and gimmick-laden spending plans as California limped from one fiscal crisis to another.

LAFAYETTE, La. - Visitors to this oil town might be forgiven for wondering whether the BP oil spill and subsequent drilling moratorium ever happened. "Now hiring" signs are plastered on billboards around town, and hotels such as the Crowne Plaza are chock full of seminars training students to work on offshore rigs. Many offshore companies can't find enough workers for the jobs they're listing. This parish has the lowest unemployment rate in Louisiana, 4.8%. Such is the opportunity on the offshore rigs that Sheila Clark, whose husband, Donald, died in the Deepwater Horizon explosion two years ago, said her 22-year-old son recently asked her how she'd feel if he went to work on a rig. "I can't stop him," said Clark, who moved to Baton Rouge after her husband's death.

Maybe the dumb money wasn't so dumb this time. The stock market did turn out to be a voting machine on Facebook on Friday (to quote Warren Buffett and Benjamin Graham), and the vote was thumbs-down on flapdoodle. Market pros will be debating the lessons to be drawn from the disastrous first-day trading in Facebook's initial public offering. But one lesson is that when given enough information, investors can find their way through fogbanks of hype. When a stock offering is as closely followed as Facebook's, it's much more likely that the shares will be fully valued than that they'll harbor hidden treasure.

Facebook Inc. is certain to make a dramatic entrance to the stock market Friday with its hotly awaited initial public offering. What's less certain is whether you should buy the stock. Enthusiasts have salivated for months over the prospect of buying into Facebook's surging growth rate and untapped advertising potential. They hope Facebook can mimic the stratospheric rise of Google Inc. in its early years, when its shares ballooned from $85 at its 2004 IPO to nearly $750 barely three years later.

BEIJING — After months of careful tinkering aimed at slowing China's supercharged economy, Chinese officials may have gotten more than they bargained for: The nation's economic engine is decelerating with alarming speed. Industrial production in April hit its slowest pace in more than three years, while growth in exports sputtered and imports were flat. In response, China's central bank over the weekend said it would ease reserve requirements for the nation's banks. The move frees about $70 billion for lending to stimulate the economy.
