STEVE INSKEEP, HOST:
And I'm Steve Inskeep. We're learning more about the victims of the Boston Marathon attack. Of three people killed, one person's name has yet to be released. Two others are known - 8-year old Martin Richard, 29-year-old Krystle Campbell.
NPR's Dan Bobkoff reports on how the news of Campbell's death tore through her hometown of Medford, just outside Boston.
From the first explosion in Boston on Monday to the second, just 15 seconds elapsed. And in those 15 seconds, three people were mortally wounded, including an 8-year-old boy. The number of injured topped 100, and for those of us watching, it was a profound reminder of a reality we'd prefer to ignore.

When you learn about the simple ingredients in the explosive devices at the Boston Marathon, you sense the challenge investigators face. The bombs included items almost anybody could buy. And so an initial look at the evidence does little to narrow down the list of suspects.
And let's talk about the Boston Marathon as a target. U.S. officials have worried for years that terrorists might go after so-called soft targets, where security is minimal and the opportunity to inflict casualties is great. People gathered in shopping centers, football stadiums, outdoor concerts are all highly vulnerable. Until now, we have largely avoided such attacks.
Salvador Castro was a Mexican American civil rights activist and fervent education reformer. He died on Monday in Los Angeles at 79 years old. Castro was revered as a teacher and mentor, and for being one of the central figures in what would come to be known as the 1968 Walkouts. These were protests by Mexican-American students that helped spark what would soon become known as the Chicano movement.
Well, yesterday was not a day that you wanted to be traveling on American Airlines. The carrier cancelled all of its main routes for several hours, and also many of its commuter flights, as well. Almost 2,000 flights were infected in all. American blames computer networking problems.
Now, the twin bombings at the Boston Marathon struck at a very special type of sporting event. Marathons have been called the most democratic of sports, with the fewest physical barriers between athlete and spectator.
NPR's Mike Pesca examines whether the attack could permanently damage that accessibility.
Yet another movie about Jackie Robinson arrived as baseball held its annual commemorative celebration of No. 42, but officials of the game are fretting over the fact that only 8 1/2 percent of current major leaguers are black.
Given that African-Americans only constitute about 13 percent of the U.S. population, and that rarely do we have any industry or school system or community population that correlates exactly to the whole country's racial or ethnic makeup, baseball's somewhat smaller black cohort hardly seems like an issue to agonize over.
Christopher Knight, whose 27 years of living in near-total isolation in Maine's wilderness made him an object of fascination after he was arrested for stealing food and supplies, appeared by video for a court hearing Tuesday, when a Kennebec County judge set his bail at $25,000 cash.

Quoting "congressional and law enforcement sources," CNN is reporting that an envelope sent to a senator's office has tested positive for the poison ricin.
"After the envelope tested positive in a first routine test, it was retested two more times, each time coming up positive, the law enforcement source said," CNN reports. "The package was then sent to a Maryland lab for further testing."
Renande Raphael, aged 16 months, is measured to check whether she is growing normally. She's part of a trial in Haiti to see if an extra daily snack of enriched peanut butter prevents stunting and malnutrition.

Babies and toddlers in the poorest parts of the world are getting better fed.
What's the proof? Stunting in kids – a sign of poor nutrition early in life — has dropped by a third in the past two decades, UNICEF reported Monday. But there's a long way to go. Globally, a quarter of kids under the age of 5 were stunted in 2011. That's roughly 165 million children worldwide, with nearly 75 percent of them living in sub-Saharan Africa and South Asia, the report says.

You know science needs to work a little harder when different teams get different values for the Hubble Constant. As <a href="http://www.pas.rochester.edu/~dmw/ast142/Lectures/Journal_club_04-11-2013_dmw.pdf">this slide from astronomer Dan Watson</a> shows, things just aren't lining up like they should.
Scientists can't just agree to disagree. It's not because we are stubborn or ornery (OK, maybe we are). It's because the whole point of science is to establish "public knowledge" — an understanding of the cosmos on which we can all agree. That is why there is trouble brewing at the beginning of the Universe.
There is a number, the Hubble Constant, that's fundamental to the study of the cosmos. The problem is, different folks are finding different values for that number and no one yet knows what that means.
