When President Obama signs an updated version of the Violence Against Women Act on Thursday afternoon, the law will include new requirements for how colleges and universities handle allegations of sexual assault.

Laura Dunn, who's been invited by the White House to attend, plans to be there.

Camels belong in the desert. That's what we've learned since grade school.

Today, NPR's Melissa Block talked to Natalia Rybczynski, a paleobiologist at the Canadian Museum of Nature, who tells Melissa that fossils she has unearthed tell a different story.

The fossils, found on a frigid ridge in Canada's High Arctic, show that modern camels actually come from giant relatives that roamed the forests of Ellesmere Island 3.5 million years ago.

The stock market's long climb from its recession bottom has some people concerned it may be a bubble about to burst — a bubble artificially pumped up by the Federal Reserve's easy-money policy. That's led to calls — even from within the Fed — for an end to the central bank's extraordinary efforts to keep interest rates low.

AUDIE CORNISH, HOST:

We turn now to the last U.S. ambassador stationed in Venezuela. Patrick Duddy represented the U.S. first under the Bush administration then later under the Obama administration. He was once expelled from Caracas. Ambassador Duddy is now a visiting senior lecturer at Duke University's Center for International Studies. When we spoke today, I asked him what it was like for him to be an ambassador to Venezuela under Chavez.

The world often feels full of fading traditions, from drive-in movie theaters to the dying art of good old-fashioned letter writing.

For the British, add brass bands to that list. Traditional brass bands have played an important cultural role in working-class British communities for centuries. But some warn that without funding, they could become a thing of the past.

Take the Grimethorpe Colliery Band in South Yorkshire. The band was originally formed in 1917, and nearly 100 years later, a group of tuba, euphonium and other horn players still bears the band's name.

Scientists are beginning to understand how people tune in to a single voice in a crowded, noisy room.

This ability, known as the "cocktail party effect," appears to rely on areas of the brain that have completely filtered out unwanted sounds, researchers report in the journal Neuron. So when a person decides to focus on a particular speaker, other speakers "have no representation in those [brain] areas," says Elana Zion Golumbic of Columbia University.

The next pope will be the spiritual leader of the world's Catholics. He will also be leading a multibillion-dollar financial empire. And from a business perspective, the Catholic Church is struggling.

We talked to several people who study the business of the church. Here are a few of the issues they pointed out.

1. Globally, the church's employees are in the wrong place.

The death of Venezuelan President Hugo Chavez is an especially tough blow for Cuba, whose feeble state-run economy has been propped up for more than a decade with Venezuelan oil shipments and other subsidies.

The Castro government has declared three days of mourning, calling Chavez "a son" of Cuba, but privately Cubans are quietly fretting about the potential loss of billions in trade and the threat of a new economic crisis.
