They are ubiquitous. They're in our cars, our computers, our TVs and the remotes that control them. They light up our streets and, increasingly, our homes. I'm talking about Light Emitting Diodes, better known as LEDs. It was 50 years ago this week that they were invented.
NICK HOLONYAK: In a way, I knew right away from how powerful this result was that we were in the right direction.
The names Columbine and Virginia Tech have both become tragic shorthand for school shootings in America. In the wake of those shootings, schools have developed a fairly typical lockdown procedure when there's a threat: sound the alarm, call police, lock doors and stay put.
The standard school-lockdown plan is intended to minimize chaos so police arriving on the scene don't shoot the wrong people. Students practice following directions, getting into classrooms and essentially, waiting.
From NPR News, this is ALL THINGS CONSIDERED. I'm Robert Siegel. Debate number two of the fall presidential campaign takes place tonight in Danville, Kentucky. This one features the number two men on the Democratic and Republican party tickets, Vice President Joe Biden and GOP nominee Congressman Paul Ryan. The debate comes eight days after a meeting between President Obama and Governor Mitt Romney.
Many Americans today feel like they've lost or are losing their shot at a college education because paying for it often seems out of reach. So how big of an issue is this in the presidential campaign?
Here's what President Obama has done to help families pay for college: He negotiated a deal with Congress this summer that kept the interest rate on government-backed Stafford loans from doubling for 7.5 million students.
Here's an astonishing fact: Half of America's mushrooms are grown in one tiny corner of southeastern Pennsylvania, near the town of Kennett Square.
But why? It's not as though this place has some special advantage of climate or soil, the kind of thing that led to strawberry fields in Watsonville, Calif., or peach orchards in Georgia. Mushrooms can grow indoors. They could come from anywhere.
Kentucky may be the site for tonight's debate between the vice presidential candidates, but the monster swing state of Ohio remains the focus of the White House dreams for President Obama and Mitt Romney.
Both the incumbent and his challenger have been in and out of the state with increasing frequency; GOP vice presidential candidate Rep. Paul Ryan plans a trip to the Buckeye State Friday, after his tangle with Vice President Joe Biden.
I'm Michel Martin and this is TELL ME MORE from NPR News. Coming up, we'll hear from a doctor who's worked with the poorest of the poor in San Francisco, opened up insights into health care for everybody. We'll hear from the author of "God's Hotel" in a few minutes.
Thursday is National Coming Out Day. That's when many LGBT people celebrate the day they came out about their sexual orientation, and encourage others. Host Michel Martin hears from one woman, Keli Pia-Miller, who explains the difficulty of coming out, and how it taught her just how much she loved her family — and how much they loved her.

It may be the undercard to the main event, but partisans on both sides are talking some trash ahead of the vice presidential debate tonight in Danville, Ky.
The pressure is particularly intense on Vice President Joe Biden, following his boss' lackluster performance in last week's presidential debate, which moved GOP nominee Mitt Romney into a national polling lead.
