Circumcision might reduce a man's risk of cancer.

Really?

It's possible, though not yet proved.

But the latest evidence in favor of protection comes from a study just published in the journal Cancer.

University of Washington researchers found a 15 percent lower risk of prostate cancer in men who'd been circumcised before they first had intercourse compared to men who hadn't been.

Tony Nicklinson wants to die.

Except he can't commit suicide because he has "locked-in syndrome," which means his mind works fine but everything below his neck is paralyzed. A 2005 stroke left the 57-year-old unable to speak and he communicates largely by blinking. His case has been making headlines in Britain because the man wants a court to OK a doctor to end what he calls his "dull, miserable, demeaning, undignified and intolerable" life.

Today, the country's high court said it would hear his case.

I'm rounding out The Salt's impromptu Pest Resistance Week (which started with stories about weeds and corn rootworms) with a little-known tale that may scramble your mental categories.

Russia was once the world leader in space exploration, but its space program has suffered a string of costly and embarrassing mishaps over the past year.

NASA says Russia is still a trustworthy partner, but critics say the once-proud program is corrupt and mismanaged — good at producing excuses, but not results.

The Memorial Space Museum in Moscow showcases the achievements of the Soviet Union's space program.

It's unlikely that the killing of 16 Afghan civilians on Sunday, allegedly by a U.S. Army staff sergeant, will drastically alter the course of the war.

U.S. and NATO strategy calls for a sizable contingent of international troops to stay in Afghanistan until 2014, with residual support after that. That timetable is unlikely to change.

But the task U.S. forces face in trying to stabilize the country could well be made more difficult by the shootings.

Hailing from the rain-soaked, indie folk hub that is Portland, Ore., the members of Y La Bamba are pretty far from their Latin inspirations. But this pop outfit is centered around the powerful, otherworldly vocals of Luz Elena Mendoza, and some of her main influences came from a childhood in Mexico — accordions, mariachi and Latin rhythms.

As soon as you step in the elevator of Las Vegas' new Mob Museum, a cop on a video monitor reads you your rights. When the doors finally open, you're greeted by a huge photo of 1920s-era gangsters standing in a police lineup, wearing fedoras.

Mississippi and Alabama hold Republican primaries on Tuesday. Former Massachusetts governor Mitt Romney scheduled a last-minute campaign event in Mobile, where he appeared on stage with the comedian Jeff Foxworthy. Former Pennsylvania senator Rick Santorum and former House Speaker Newt Gingrich both addressed an energy summit in Biloxi.

When presidents give major set-piece speeches, they're mainly engaged in exercises in futility since a commander-in-chief's high-flown rhetoric rarely shifts voter attitudes for long.

Indeed, the exercise could even be more negative than neutral since speeches by presidents advocating specific policy not only leave citizen unswayed but can fire up political opponents in the other party, according to Ezra Klein in an essay in the New Yorker.

With a fierce yell and a resounding thwack, 13-year-old Japanese student Nanami Usui brings her bamboo sword down on her opponent.

By practicing Kendo, or Japanese swordsmanship, Usui is one of several students in the town of Minamisanriku who are rebuilding their confidence after last year's tsunami washed away their homes and shattered their hometown in the country's northeast.

Usui says she dreams of being a police officer, but she doesn't know yet where she wants to live and work.

In a report issued today, the board of directors of Penn State University confirmed what everyone already figured: They fired head coach Joe Paterno over his actions concerning the sexual abuse allegations against his once assistant coach Jerry Sandusky.

The university said it made its decision based on a grand jury report that said graduate student Mike McQueary had told the coach that he saw Sandusky "in the Lasch Building showers fondling or doing something of a sexual nature to a young boy."

The board says:

The Gaithersburg, Md., priest who refused to give Communion to a lesbian parishioner during a funeral mass for the woman's mother has been has been placed on leave, according to NBC Channel 4 news.

A letter from an archdiocese official says that Rev. Marcel Guarnizo was placed on leave for engaging in intimidating behavior. The archdiocese had previously apologized for Guarnizo's behavior.

Many details remain unknown about Sunday's shooting in southern Afghanistan, where a U.S. Army sergeant is suspected of walking through villages near Kandahar and killing 16 Afghan civilians.

But the shooting has raised the specter of reprisals against American troops and also led to questions about how much damage it could cause to the larger American war effort in Afghanistan.

Here's a look at what is, and isn't, known so far.

The Suspect

We're all familiar with the gruff Richard Nixon of the Watergate tapes. But the presidential library of the 37th president of the United States has an exhibit that shows a different side of him — the softer, gushy side of him that emerged as he was courting Pat Ryan, the woman who would become his wife.

In the past decade or so, we've gotten used to jobless recoveries, when the economy grows its way out of a recession without adding many new jobs.

At the moment, we may be living through the opposite of a jobless recovery. In the past few months, job growth has picked up, while economic growth has slowed.

The United Nations special rapporteur on torture has reached the conclusion that the United States violated some of the rights of the Army private accused of leaking classified information to WikiLeaks.

Pfc. Bradley Manning has been in U.S. custody since May 2010 and as we've reported, Juan Méndez, the U.N.'s top torture official, has already had some tough words for the U.S. leading up to this report.

Peter Bergman, one of the founding members of the four-man surrealist comedy troupe The Firesign Theatre, died Friday of complications from leukemia. He was 72.

Bergman, along with collaborators David Ossman, Phil Proctor and Phil Austin, created satire out of the political and civil upsets of the 1960s and 1970s, blending surrealism, absurdities, non sequiturs, paranoia, parodies of the Establishment, sound effects, in-jokes about hippies and knowing allusions to literature and trash culture.

Farms may conjure an image of a pastoral landscape, with children running and frolicking in green pastures. But farms do come with their own dangers. And there's plenty of argument on what should be done to ensure the safety of children who live or work on farms.

The U.S. Department of Justice has blocked a new voter ID law from going into effect in Texas. The department says the state failed to show that the law would not deny or limit minorities' right to vote. It's the second state voter ID law the department has blocked.
