It's about a week after it became available on the Internet but no less interesting now than it was then is the infographic by Craig Newmark, founder of Craigslist, which skewers voter ID laws cropping up in various states. One of his points — the cure is far worse than the disease.

A disease that has killed more than 5.5 million bats in the eastern United States and Canada is making its way west. White-nose syndrome has now been diagnosed in three Missouri bats — the first confirmed cases west of the Mississippi. And scientists say it won't stop there.

Federal agents interviewed new witnesses this week in an ongoing investigation of government scientists that's been called "polar bear-gate," according to the scientists' lawyer.

The controversial probe, now entering its third year, is looking into allegations of scientific misconduct related to a 2006 report by wildlife researchers Charles Monnett and Jeffrey Gleason, who described seeing dead polar bears floating in Arctic waters.

We still don't know who bought the three winning tickets in Friday's $656 million Mega Millions lottery drawing — one in Illinois, one in Kansas and one in Maryland.

And we still don't know what's going on with Mirlande Wilson, the Maryland woman who has made headlines by claiming to have purchased a big winner, but who hasn't yet provided any proof.

Tens of millions of Americans turn to powerful painkillers to ease their sufferings. But an analysis on the sales of two prescription drugs over a decade is particularly worrisome.

The prosecutor investigating the shooting of Trayvon Martin in Sanford, Fla., has not yet decided if she will bring charges against the shooter, George Zimmerman.

It took several weeks for the Feb. 26 shooting to draw the nation's attention — after Benjamin Crump, the attorney for Trayvon Martin's family, launched a campaign to get the case before media and civil rights activists nationwide.

Two days after the shooting, the high-profile civil rights attorney started getting calls about the case. "My phone was buzzing," Crump says.

A Russian computer security firm says it has discovered that about 600,000 Apple computers have been infected with a "Flashback Trojan" virus.

Now, before we move on, you should know that the company making the announcement is Dr. Web, which sells anti-virus software that will protect a computer against that kind of virus. It's also important to note that many of the parties weighing in are part of a security community that makes money off selling anti-virus software.

Tonight, in Whitesville, W.Va., mourners will silently walk with candles on sidewalks lined with luminary lights to remember the 29 coal miners who died two years ago today in the nation's worst mine disaster in 40 years.

That memorial will follow a 3 p.m. ET event in Beckley,W. Va., where an honor guard will ring a bell 29 times to mark the moment the Upper Big Branch coal mine erupted in a massive explosion.

Dennis Walcott oversees a school system with more than one million students. Graduation rates are below the national average, and studies suggest most of the city's high school graduates are not ready for college. But Chancellor Walcott tells host Michel Martin that, after one year on the job, New York City schools are on the mend.

Race is central to the debate surrounding Trayvon Martin, the black Florida teen shot by neighborhood watch volunteer, George Zimmerman. Many media outlets first identified Zimmerman as "white," but his father describes him as a Spanish-speaking minority. Host Michel Martin explores the question, "who is white?" with sociologist Jean Halley.

In the turf war between rabbits and bilbies that plays out in burrows dug into Australia's arid grasslands, rabbits, those aggressive and fertile European immigrants, have largely won out.

But the chocolate bilby has staked its claim on the springtime candy shelf — an honor that could help the threatened species make a real comeback.

Mitt Romney has been far and away the best-funded of the Republicans running for president. In addition to his own campaign chest, he has the wealthiest superPAC backing him, Restore Our Future.

Among the donors to Restore Our Future, are hotel tycoons J.W. and Richard Marriott. Each gave $750,000 so far this campaign cycle.

Humble Roots

Mitt Romney has taken the lead in voter support in Pennsylvania, according to a new poll from Public Policy Polling which shows the Republican frontrunner ahead of Rick Santorum, the former U.S. senator from the Keystone State, 42 percent to 37 percent. That lead was just on the 4.9 point margin of error, suggesting a tie. That's bad news for Santorum, however, as he dropped six percentage points while Romney gained 17 percent from a month ago.

The number of people filing first-time claims for unemployment insurance stayed around a four-year low last week, the Employment and Training Administration just reported.

It says there were 357,000 such applications, down 6,000 from the previous week's revised figure of 363,000.

Claims have been running at the lowest rate since March and April 2008 for several weeks now.

The last big ice age ended about 11,000 years ago, and not a moment too soon — it made a lot more of the world livable, at least for humans.

But exactly what caused the big thaw isn't clear, and new research suggests that a wobble in the Earth kicked off a complicated process that changed the whole planet.

Ice tells the history of the Earth's climate: Air bubbles in ice reveal what the atmosphere was like and what the temperature was. And scientists can read this ice, even if it's been buried for thousands of years.

Six-term Republican Sen. Richard Lugar of Indiana is facing his first primary challenge since winning the job in the 1970s. The race is attracting big money from outside groups and superPACs, and is seen as a test of the strength of the Tea Party movement versus the power of incumbency.

Two of America's best-known companies, Coca-Cola and PepsiCo, have dropped their memberships in the American Legislative Exchange Council, a low-profile conservative organization behind the national proliferation of "stand your ground" gun laws.

If there's one building in Jerusalem that represents the city's tangle of religions, this is it. The ground floor is a Jewish holy site said to house the tomb of the biblical King David. The second floor is the Cenacle, a Christian holy site, the room believed to be the site of Jesus' Last Supper. On the roof, there's an old minaret from when this place was marked a Muslim holy site.

One building, three religions, decades of property disputes. And the fight isn't over.

April 6 marks the 20th anniversary of the start of the Bosnian war and the siege of Sarajevo. It was the longest siege of a capital city in modern history, and produced the worst atrocities in Europe since World War II.

Over three-and-a-half years of war, 100,000 people were killed, and half of Bosnia's population of 4.4 million — made up of a plurality of Muslims — fled their homes.

A final report from Los Angeles coroner is shedding some light on Whitney Houston's last hours.

According to the report, the pop super star complained of a sore throat and an assistant suggested she take a bath. By the time the assistant got back to the room after running an errand, she found Houston lying face down on in the tub "in approximately 13-inches of water," People Magazine reports.

What's plentiful in upstate New York? Cows and prison inmates, to name a few things.

Reformists in the two communities don't make natural allies, but organizer Lauren Melodia is trying to do just that.

"I was living in this prison town, and at the same time, the dairy industry was in a lot of turmoil," Melodia tells The Salt. "We thought this [dairy] might be the perfect ally in trying to build a different economy in upstate New York, and shift some of the economic dependency away from the prison system."

Much of the Republican political establishment, many GOP voters and political analysts were telling Rick Santorum that the time had come for him to end his quest for his party's presidential nomination even before Tuesday when he failed to win any of three primaries.

Those calls had only increased by Wednesday as Santorum fell further behind Romney in the delegate count.

Growing up in Miami, there seemed to be two eternal debates: When Castro would finally kick the bucket and when the city would get its act together and strike a deal for Los Marlins to finally get their own stadium. The franchise spent its first 19 years sharing a stadium with the Miami Dolphins. For baseball, the stadium was cavernous and uninviting.
