No conversation, no matter how meaningful and powerful, can bring back the millions we've already lost to suicide. But we may very well prevent the next loss to suicide if we can all continue to break the silence and share our journeys.

Dr. Jill Biden

Second Lady of the United States

This Memorial Day, I hope you will take a moment to offer your own gesture of thanks to our men and women serving abroad and at home, as well as their families, and take a moment to honor the service men and women who have made the ultimate sacrifice.

J. J. Abrams and Bryan Burk

When we began work on Star Trek Into Darkness, we realized it would be released in May 2013, a moment when our nation would have the opportunity and responsibility to make sure we help these post-9/11 veterans transition back to jobs, higher education, or ongoing careers of service.

Mohamed A. El-Erian

CEO and co-CIO, PIMCO

Allow me please to take you back for a moment to the beginning of 2011. Remember how surprised the world was that, in just 18 days, a leaderless grass-root uprising managed to topple the Mubarak regime that had ruled Egypt with an iron fist for 30 years?

All these men are honorable. None has broken any law. But they and their ilk in congress -- the Democrats who are now rolling back Dodd-Frank -- don't seem to appreciate the extent to which Wall Street has harmed, and continues to harm, America.

Bernard-Henri Lévy

French philosopher and writer

The honor of Muslims is Islam, simply Islam, when it is true to its principle, which signifies (as everyone knows, but unfortunately, some have often forgotten): peace.

Marian Wright Edelman

President, Children's Defense Fund

America has a spiritual problem when it protects guns rather than children. Why are we not all calling our legislators and expressing outrage? How can we let the voices of gun dealers and manufacturers drown out the cries of children?

If you're one of the many families getting ready to get away from it all this summer, here are some tips for a stress-free summer vacation.

When I was a child, the only women you were likely to encounter on the front lines of America's military didn't wear uniforms. Instead, they wore high heels, hose and sequins. That's because these women were not among our soldiers but, instead, part of the U.S.O.

Why should middle-class students pay more for loans than is absolutely necessary, all the while padding the government's coffers and enabling state universities to build facilities that the students will only get to use for four years?

Arianna Huffington

In this week's special summer issue, we're putting the spotlight on all the season's diverse offerings, with an emphasis on ways to enjoy the summer with less stress -- from guides to the best of entertainment, culture and lifestyle to tips and new twists on how to make the most of beloved summer pastimes.

Western anti-Muslim sentiment needs to be balanced by Muslims voicing their determination to confront the Islamist threat and expose the abuses of Islam by a small minority of extremists.

Continuing to ban lesbian den mothers and gay scoutmasters is sending a horrible message to American youth, including the scouts, gay and straight. The Boy Scouts of America made this change to take some of the heat off, and no matter what equality advocates hope for, that will happen.

Brian Levin, J.D.

Director, Center for the Study of Hate and Extremism, California State University

Omar Bakri Mohammed, 54, who has harnessed a dangerous sliver of American and British youth to religious terror and extremism is a notorious English-speaking hate cleric who for almost two decades, while on public assistance, fomented radicalism in the United Kingdom.

If the Waltons really wanted to make positive change in children's educations and lives, they would steer far clear of Michelle Rhee and her troublesome track record.

Lea Lane

Sometimes, especially when a person seems to have a satisfying life, we dismiss suicidal signals that would otherwise alert us. I know this first-hand.

Liz Kozak

Writer, Mom

I know deep down that she's the little person she's meant to be and that she's on her own journey and that she is in fact human -- not a snorty piglet. But I can't get one irksome question out of my mind.

Ever since the Keystone fight began, the smart money has insisted the pipeline will be approved. But so far: no pipe.

Brenda Chapman

Brave Writer and Co-Director

The message Disney sends to the public in changing Merida is that she is not good enough the way she is. In doing that, they are making the same statement to all the young girls out there.

Jeffrey Bland, Ph.D

President, Personalized Lifestyle Medicine Institute

More and more, health professionals from varied fields put their energies, time and money toward gaining the knowledge and experience necessary to effectively embrace the power of nutrition. But astonishingly, health professionals with nutrition tools to reverse chronic health conditions are gagged in many states.

Elliott Negin

Director of News & Commentary, Union of Concerned Scientists

Every time journalists cite contrarian scientists or industry-funded think tank spokespeople, they validate them as a trustworthy source. And every time journalists fail to disclose where contrarians get their funding, they fail to explain whose interests they serve.

Martha Burk

Money Editor, Ms. magazine; director, Corporate Accountability Project, National Council of Women's Organizations

Let's hope when the next Memorial Day rolls around, the good news will be that changes have been made. Our military women deserve to be safe from attack by their own ranks. Those who assault their peers and dishonor the country in the bargain deserve to be punished, not protected.

Dennis Kravetz

Psychologist, physical fitness buff, business consultant and writer

What does it mean to be "psychologically young"? It's not about wrinkle creams, plastic surgery, or injections to make you look younger. It's about having a positive mental attitude, staying cognitively and physically active, and having a high-quality life.

Jim Wallis

On Tuesday, the Senate Judiciary Committee approved a new comprehensive immigration reform bill with a bipartisan vote. It isn't perfect, but the key elements that many of us have been fighting for are intact. That really is a triumph of the common good.

Lee Woodruff

Co-author, 'In an Instant', Author, 'Perfectly Imperfect', Author, 'Those We Love Most'

On Memorial Day, we'll remember those who died in service to our country. But this year, my thoughts are also with our injured service members and their families -- the folks who carry the biggest burden when loved ones return, different, broken, hurting.

Brynn Tannehill

Defense research scientist

When the Mormon Church officially endorsed the Boy Scouts' new "young gays OK, grown-up gays bad" position, I pricked up my ears. I asked myself, "What does this organization have to gain from it?" Simply put: everything.

What can we do? How can we avoid frequent criticism and still provide children with the guidance and instruction they need?

Jim Moret

Let's stop this madness. Take away the cameras and microphones and put her away for good. Jodi Arias may still long for her close-up, but this mistrial is a wake-up call to silence her voice.

This 50th anniversary reminds me that in the David-and-Goliath-like battle that pitted Martin Luther King, Jr., school children and the best of the Civil Rights movement against the Ku Klux Klan and white racists -- active nonviolence can transform anything.
