All Things Considered

Eight people died Wednesday in a fire at a Bangladeshi sweater factory. This follows the much deadlier collapse of the Rana Plaza building, where more than 900 people died.

The deaths are taking place in a garment sector that has seen explosive growth over the past three decades. The country has managed to lure clothing-makers through a combination of low wages and light regulation.

As a manufacturing center, Bangladesh has little to recommend it. The roads are poor. There's no port to speak of. The electricity is notoriously unreliable. It's politically unstable.

In 1961, Mel Brooks and Carl Reiner came up with some basic theories of caveman linguistics in their 2,000-Year-Old Man skit. Most of them had to do with rocks, as in, "What are you doing with that rock there?"

Now, a professor in England has questioned the validity of the famous caveman's rock-centric theories. And Mark Pagel of the University of Reading is reaching even further back, to the time of the 15,000-year-old man.

Flags of the competing political parties whip in the wind of seaside Karachi. But little else is stirring in this city of 18 million this day.

The MQM, a leading political party in the megacity, has shut Karachi down with a general strike in response to a deadly bombing at its election office. But as soon as the strike ends, the streets spring to life as if nothing were amiss.

Journalists make choices all the time that influence our understanding of the news — the choice of what stories to cover, which people to interview, which words to use. And major news organizations have been reconsidering how best to describe a group of people whose very presence in this country breaks immigration law.

This is the tale of turkey tail — it's convoluted arrival, disappearance and highly anticipated return to the Pacific island the Republic of Samoa (not to be confused with American Samoa).

It's hard to pinpoint precisely when turkey tails started being imported into Samoa from the U.S. and when they became a favorite, affordable dish. Meat byproducts (Spam and fatty lamb cuts from New Zealand) started showing up sometime after World War II, and turkey tails came shortly thereafter.

A study of genetically identical mice is providing some hints about humans. How can one identical twin be a wallflower while the other is the life of the party?

The study of 40 young mice found that their behavior grew increasingly different over three months, even though the mice shared the same genes and lived in the same five-level cage, researchers report Thursday in the journal Science.

The House Homeland Security Committee held its first hearing on the Boston Marathon bombing and aftermath on Thursday. Witnesses included the Boston police commissioner and former Sen. Joe Lieberman. Panel Chairman Mike McCaul has been highlighting intelligence failures.

President Obama turns his attention back to his economic agenda Thursday when he travels to Austin, Texas, where he will visit a technology high school and a company that makes the machines that make silicon chips.

The White House says the trip is part of Obama's Middle Class Jobs and Opportunity Tour. It also appears to be an effort by the president to get back to the issues Americans care most about.
