On Monday, researchers at the Harvard School of Public Health released study results showing that red meat consumption was associated with a higher risk of early death. The more red meat -- beef, pork or lamb, for the purposes of the research -- study participants reported they ate, the more likely they were to die during the period of time that data collection took place (more than 20 years). So what is it in red meat that might make it unhealthy?   No one is sure, exactly, but the authors of the Harvard study mention a few possible culprits in their paper in the Archives of Internal Medicine .   First, eating red meat has been linked to the incidence of heart disease.  The saturated fat and cholesterol in beef, pork and lamb are believed to play a role in the risk of coronary heart disease .  The type of iron found in red meat, known as heme iron, has also been linked to heart attacks and fatal heart disease.  Sodium in processed meats may increase blood pressure, which is a risk factor for heart disease. Other chemicals that are used in processed meats may play a role in heart disease as well, by damaging blood vessels.

The Los Angeles City Council approved a long-awaited federal financing agreement that will help ensure a vital transportation corridor doesn't become a drain on the finances of the ports of Los Angeles and Long Beach. The vote — 13 to 0 in favor, with two council members absent — allows the Alameda Corridor Transportation Authority to accept $83.7 million from the Federal Rail Administration to help fund operations of the Alameda Corridor, a 20-mile freight rail expressway linking the ports to transcontinental rail lines.

Teas from across the globe are becoming more and more popular in the U.S. One relative newcomer, yerba mate, is attracting fans for its allegedly jitter-free caffeine boost and high antioxidant content. Lab research suggests some potential health benefits from drinking yerba mate, but studies of lifelong yerba mate drinkers in the tea's native South America suggest the brew increases the risk of some cancers -- a fact most marketing campaigns omit.

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.

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.

The U.S. healthcare system is lagging further and further behind other industrialized countries on major measures of quality, efficiency and access to care, according to a new report from the nonprofit Commonwealth Fund, a leading health policy foundation. That is having a profound effect on overall health in the U.S., the report found. Americans die far more frequently than their counterparts in other countries as a result of preventable or treatable conditions, such as bacterial infections, screenable cancers, diabetes and complications from surgery.

Slake, a new showcase for long-form journalism, seems not only bent on resuscitating passionate reporting but also the grand tradition of literary partying, which can be a dangerous enterprise with a bunch of people who revel in the joys of a multi-clause sentence. The local magazine will host a night of readings from its second issue, themed "Crossing Over. " Authors will include Dana Johnson, John Albert, Joseph Mattson, Victoria Patterson, Rachel Resnick, Harry Shannon and Joe Donnelly.

Depending on how one counts, it was a meeting either six months or almost 20 years in the making. The major participants? Two pop-culture luminaries. One was Angelina Jolie, the Oscar winner who launched 1,000 paparazzi and carried off with swagger such action flicks as "Wanted" and "Lara Croft: Tomb Raider." The other was Patricia Cornwell, one of the world's most commercial authors. The topic was Kay Scarpetta, Cornwell's signature character, the medical examiner in 17 mystery novels.

No one is exactly sure how a mountain lion roamed into the heart of Santa Monica on Tuesday morning, coming face to face with the janitor of an office complex not far from the city's bustling shopping district. But it turned out to be an unwelcome visitor - and that generated much debate in the city. With news choppers circling overhead, Santa Monica police managed to corner the 3-year-old lion in the courtyard of the complex. Police said they made several attempts to contain what they described as an aggressive feline using tranquilizing darts, nonlethal bullets and a fire hose.

The Man Who Changed the Way We Eat Thomas McNamee Free Press, 339 pp., $27 Ask your average Food Network viewer or Yelp poster about Craig Claiborne and you're likely to be met with a blank look and a "Who?" How fleeting is fame in the food world. Claiborne is one of the giants of this modern age, even if today - less than 20 years after his passing - he is largely forgotten. People remember James Beard because of the foundation that keeps his name alive. Julia Child lives on in television reruns (even if some fans now believe she looked just like Meryl Streep)

These days, the sound of the digital scythe being whetted makes me cast more lingering looks at the paper and cardboard relics on my bookshelves. At none more, since the announcement in March of their imminent extinction, than the familiar brown and gold, oddly titled volumes of my 1958 Encyclopedia Britannica: HYDROZ to JEREM, MARYB to MUSHE, SARS to SORC. During my teenage years, when my thirst and respect for knowledge were at an unsustainable peak, I resolved to read the Britannica from one end to the other.

A New York federal judge temporarily blocked enforcement of a provision in the National Defense Authorization Act that opponents contend could subject them to indefinite military detention for political activism, news reporting or other 1st Amendment activities.

Obama signed the bill into law Dec. 31. The complaint was filed Jan. 13 by a group including former New York Times reporter Christopher Hedges.

SAN MARCOS, Calif. —When paramedics arrived at the Purdy home March 20, Margaret was seated in her favorite chair in the living room. The morning sunshine streamed in through a picture window that overlooked a valley. A plastic bag was over her head, tied securely at the neck. A suicide note in her handwriting was in a folder on her desk, beneath a shelf with books about death and dying. She had written that the pain from her various medical conditions had become unbearable. Alan Purdy met the paramedics at the door.

MOSCOW — Russian riot police cleared a Moscow park early Wednesday of a weeklong encampment considered a local version of the Occupy movement, and hours later clashed with antigovernment protesters outside a Stalinist skyscraper in a different part of downtown. The dispersal of several dozen protesters at the park encampment, called Occupy Abai, preceded a nighttime confrontation at Kudrinskaya Square, where several hundred protesters had gathered to oppose President Vladimir Putin.

NEW YORK -- About a year ago Mary Ann Naples had a holy-cow moment. If she'd been a cartoon character, she would have smacked her forehead until stars came out. She was standing atop an escalator at Book Expo America, the publishing world's spring jamboree in New York, surveying a convention hall of sullen faces. Many of the 30,000 booksellers, publishers, authors and agents were looking like well-heeled passengers on a leaky cruise ship. The rise of digital books and online retailing was upending book publishing's business model.

WASHINGTON - Overcoming objections from conservatives, Congress gave final approval to legislation to reauthorize the nation's Export-Import Bank, sending to President Obama a key legislative priority for the business community. The Senate passed the measure 78 to 20 after turning back several proposed GOP amendments to do away with the bank or scale back its lending authority. Conservatives in the House and Senate have fought the bank as a form of corporate welfare. The bank subsidizes the sale of U.S. exports, which critics said props up some companies and harms others through unfair competition.

In One Person A Novel John Irving Simon & Schuster: 426 pp., $28 Late in John Irving's 13th novel, "In One Person," the narrator, an aging writer named William Abbott, recalls visiting a high school friend dying of AIDS. It's the early 1980s, the beginning of the AIDS crisis, and Irving evokes the deathly terrors of that period, a time when people seemed, literally, to evaporate, to become, in the words of the late David Wojnarowicz, "a dark smudge in the air that dissipates without notice … glass human[s]
