It's been used by brands such as American Airlines, Panasonic and Toyota. It's all over the signage in the New York City subway system. Even Google, Apple and Netflix used it for a time.

Helvetica is ubiquitous around the world, but despite its popularity, the typeface has some issues: letters scrunch together at small sizes and the space between them can be uneven.

Now, after 36 years, the widely used — and widely controversial — font is getting a makeover.

Twenty years ago, a pair of students killed a teacher and a dozen of their classmates a high school in Littleton, Colo. The shooters at Columbine High School used semiautomatic weapons and sawed-off shotguns in the attack before turning the guns on themselves.

Just a few months before that shooting, the FBI launched the National Instant Background Check System to try and prevent dangerous individuals from purchasing guns.

The latest book-length tell-all on life inside President Trump's White House has appeared, and it's just as unsparing about dysfunction and deception as all those earlier versions by journalists, gossip mavens and former staffers. Maybe more so.

The difference is that the president likes this one.

Or at least he says he likes it. And it's probably not because of the catchy title (Report on the Investigation Into Russian Interference in the 2016 Presidential Election), or any previous works by the author, Special Counsel Robert S. Mueller III.

Now, there's renewed interest in giving adults behind bars better access to higher education. A new bipartisan bill in Congress would allow incarcerated people to use federal Pell Grants — designed for low-income students — to pay for higher education, including college classes and workforce training.

The tunnel leading to Colombia's most famous church feels more like a byway into the bowels of the earth. It's dark and dank, with a faint smell of sulfur in the air. But after a few hundred yards, the shaft gradually widens to reveal Roman Catholic icons, like the Stations of the Cross and Archangel Gabriel.

And they're all carved out of salt.

Is it possible to raise children without shouting, scolding — or even talking to kids with an angry tone?

Last month, we wrote about supermoms up in the Arctic who pulled off this daunting task with ease. They use a powerful suite of tools, which includes storytelling, playful dramas and many questions.

Austin Mayor Steve Adler opened the annual State of the City address Wednesday with a quote from Charles Dickens: "It was the best of times, it was the worst of times."

The nation was shocked on April 20, 1999, when 12 students and one teacher were killed in a mass shooting at Columbine High School outside of Denver, Colorado.
