Scientists have discovered a new subatomic particle with profound implications for understanding our universe. On Wednesday, they announced they've found a particle believed to be the long-awaited Higgs boson. Nicknamed the "God particle," it represents the final piece in a theory that explains the basic nature of our universe.

As we celebrate all things American on the Fourth of July, we often remember the great minds that have shaped our nation's history.

But this afternoon, as you're devising new techniques to get slow-moving ketchup from the bottle to your hot dog, you're also celebrating the birthday of another innovative American: Pulitzer Prize-winning cartoonist Rube Goldberg.

Two teams of scientists using the Large Hadron Collider at the European Organization for Nuclear Research, or CERN, announced in Geneva this morning that they have detected a new subatomic particle that bears the hallmarks of the elusive and highly sought after Higgs boson. In layman's terms, the Higgs is referred to as the "God Particle" because the field it produces gives atoms their mass. Were it not for the Higgs, the world we know would be completely different — there would be no chemistry, no architecture, no us.

Forty-four soldiers and Marines in Afghanistan are celebrating this Fourth of July as American citizens for the first time after their naturalization ceremony at Kandahar Air Field.

As the morning sun beat down on the desert base last Friday, hundreds gathered inside the air-conditioned assembly hall for the ceremony. American flags lined the walls, patriotic music played, and smiles were everywhere.

The Catholic Church is drawing a line in the sand.

Perceiving its core beliefs to be under threat from popular culture, the White House and even Catholics themselves, the Vatican and the U.S. Conference of Catholic Bishops are pushing back.

In recent months, the church leadership has been cracking down on liberal theologians, disciplining nuns and emphasizing a more orthodox theology.

Twenty-four years ago, Morning Edition launched what has become an Independence Day tradition: hosts, reporters, newscasters and commentators reading the Declaration of Independence.

It was 236 years ago this Wednesday that church bells rang out over Philadelphia, as the Continental Congress adopted Thomas Jefferson's draft of the Declaration of Independence.

Below is the original text of the Declaration, alongside photos of the NPR staff members and contributors who performed the reading.

A very small percentage of Americans are now serving in the military — fewer than 1 percent. Some are looking for direction. Others are inspired by a sense of patriotism or by a family member who served in an earlier war. On this Independence Day, we continue with an occasional series, Those Who Serve, a look at the men and women wearing their country's uniform during a time of war.

Capt. Jared Larpenteur is from Cajun Country in Louisiana. His family never expected he'd make the military his career.
