Here's the latest bit of evidence that exercise keeps the brain fit. Much of the research has been in older people, but this study found that being fit in your 20s makes you sharper in middle age.
Thirteen years in the making, the Prison Rape Elimination Act is starting to have an impact. Texas Gov. Rick Perry says it's "ill-conceived," but many other states are adopting the law's standards.
The incumbent mayor of the nation's capital will not be re-elected. A federal investigation into Vincent Gray's 2010 campaign, along with allegations lodged just weeks before the election, helped propel his closest opponent to a surprise double-digit victory in the Democratic primary.
Attitudes toward drug use continue to evolve. A new poll from the Pew Research Center shows that more people favor alternatives to prison for non-violent drug offenders.
Adam Lioz, of the public policy organization Demos, says that Wednesday's Supreme Court ruling will further empower a small, elite group of political donors. He offers a critical perspective on the ruling.
A divided Supreme Court eliminated the overall limits on a donor's contributions to federal candidates and campaigns, while leaving in place the limit on what a donor may give to one candidate.
Texans overwhelmingly choose cars and trucks for their commutes, but in cities like Houston, Dallas and San Antonio, policy leaders have incentives to support cycling. They say it's good for business.
The IRS has not audited a church in five years. Some televangelists are taking advantage of that inaction to shield millions of dollars from public scrutiny.
From the Marketplace Datebook, here's a look at what's coming up Thursday:

What's the best sound to pair with wafting coffee smells? What's the right song for the tomato sauce on your pizza? What's most ideal aural ambiance for your milkshake?
Lucy Hooker is a reporter with the BBC. She has been looking into a field called "neurogastronomy," or, in plain terms, "what your brain does when you eat something."
She points to one study in which scientists gave people a dessert and played different sounds while they were eating. Depending on which sounds were played, a dessert could taste more bitter or more sweet.
Starbucks liked the idea so much, they asked the scientists behind the research to compile a playlist of songs people should listen when drinking coffee at home. Hooker said Starbucks is not the only major company interested in this research.
“Lots of the really big food companies -- Unilever, Nestlé -- have massive research and development units, and they are putting a lot of effort and a lot of focus into seeing how they can use our different senses," said Hooker. "How they can combine the sound a food makes in our mouth, the sound of the packaging, the sight of it, the smell of it."
In nine months the human brain grows from a single cell to more than 80 billion. Mapping how genes are activated gives scientists clues to the origins of mental disorders like autism.
The NSA managed to penetrate the networks of the giant Chinese telecommunications firm Huawei, documents show. Journalist David Sanger says cyber-espionage is an "entirely new field of conflict."
A risque campaign that aims to boost self-exams for breast cancer has reignited a debate about whether they prevent cancer deaths. One doctor says it's time to change how women look for lumps.
Charles H. Keating Jr. in court in Los Angeles in 1992. Convicted of fraud, racketeering and conspiracy in state and federal trials, Mr. Keating went to prison for four and a half years.
Charles Keating, who died this week, is best-known as the poster boy for the savings and loan crisis of the 1980s. More than 1,000 banks failed, and taxpayers spent a quarter-billion dollars bailing them out.
Here are a few of his more colorful legacies:
1. Keating gave birth to John McCain as-we-know-him. By making McCain a figure of shame.
Keating's status as the king of the S&L swindlers rests on his sponsorship of the "Keating Five": a group of five U.S. Senators whose campaigns he supported financially-- and who in turn attempted to dissuade regulators from investigating Keating's shenanigans. The sole Republican in the group was John McCain, then a relatively new U.S. Senator. McCain later called the episode "my asterisk" -- and became better-known as a bi-partisan crusader for campaign-finance reform.
2. Also on Keating's payroll in the 1980s: Alan Greenspan.
As a private economist, Alan Greenspan took on a consulting job for Keating in 1984. His job: Drafting a report to regulators, arguing that Keating's bank, Lincoln Savings and Loan, be exempted from certain rules because it was well-run.
3. He was good for a shameless quote.
From the New York Times obituary: "Mr. Keating, a 6-foot-5-inch beanpole who walked with a swagger, never minced words about buying political influence. Asked once whether his payments to politicians had worked, he told reporters, 'I want to say in the most forceful way I can: I certainly hope so.'”
4. He did like to peddle shame.
In the late 1950s and early 1960s, Keating was a huge anti-pornography crusader. He sponsored a hilarious infomercial The Atlantic called “The Reefer Madness of porn.”
5. We can thank him, in part, for financial tools that later blew up in 2008.
Roy Smith teaches finance at NYU. And he spent much of the 1980s at Goldman Sachs. "You have to remember that the S&L crisis actually spawned two of the financial industry's most lucrative product streams," he says. "One was the securitization of mortgages into mortgage-backed securities. Hello! Those things that blew up in 2008..."
They were created for sale to savings and loans. "The other was the derivatives business."
Smith says it took more deregulation, time, and financial creativity for both products to cause problems.Marketplace for Wednesday April 2, 2014by Dan WeissmannPodcast Title: Keating's legacy, from John McCain to a camp classicStory Type: News StorySyndication: SlackerSoundcloudStitcherSwellPMPApp Respond: No

Bill Gates sits next to students at Booker T. Washington high school in Miami, FL.
A victory for privacy advocates in New York spells trouble for a national effort to track student data--everything from grades and test scores to disabilities and suspensions. The New York State Education Department has confirmed it will no longer store any student information with the non-profit inBloom. That makes New York the last big customer to drop out of an initiative backed by the Gates Foundation and the Carnegie Corporation. Once boasting nine states as potential customers, the nonprofit group says it’s still talking with individual school districts around the country.Marketplace for Wednesday April 2, 2014by Amy ScottPodcast Title: An uncertain future for big data in educationStory Type: News StorySyndication: SlackerSoundcloudStitcherSwellPMPApp Respond: No
