Top influenza researchers around the world published a statement back in January saying they would temporarily hold off on any work with contagious, lab-altered forms of a particularly worrisome form of bird flu.

The unusual voluntary moratorium was supposed to last only 60 days, but it's been more than six months. And scientists don't agree on what should happen next.

Stop by most any unirrigated farm across the lower Midwest and you'll see crops in distress. Midwestern corn and soybean farmers are taking a beating during the recent drought, but it's not likely to drive many out of business.

Most of those farmers carry terrific insurance, and the worse the drought becomes, the more individual farmers will be paid for their lost crops. The federal government picks up most of the cost of the crop insurance program, and this year that bill is going to be a whopper.

Among those on Mitt Romney's list of potential running mates, Wisconsin Rep. Paul Ryan has youth and experience, he's a conservative from a swing state, and he has big ideas and the policy chops to back them up.

But the chairman of the House Budget Committee would not be the safest of choices.

Back in February, when the Republican primary was still in full swing and the party's right wing was conspicuously unhappy with the idea of Romney, tax hawk Grover Norquist spoke to the Conservative Political Action Conference.

I'm standing next to a ridge, looking at the Syrian town of Salaqin. Just up on the ridge you can see the silhouettes of a mosque and couple of water towers. It looks like a very small, inconsequential town, but because it's on the Syrian-Turkish border it's very important to the rebels.

What the Syrian rebels are trying to do right now is carve out a kind of safe zone, a buffer zone where they can gather, assemble and plan attacks against the Syrian regime's army, and also a place where they can move weapons and money into Syria.

Republican presidential candidate Mitt Romney speaks to the Veterans of Foreign Wars in Reno, Nev., on Tuesday. It's a sort of launching pad for a foreign trip that will take Romney to three countries over the next week: the United Kingdom, Israel and Poland.

Romney, a man with a lot of domestic policy experience, is now trying to demonstrate his proficiency with international affairs.

One of the great things about jazz is that it bridges generations. Because it relies on interactive improvisation and live performance, and thus can't be completely taught in a classroom or with a book, aspiring younger musicians seek the direct guidance of older, wiser ones. And more experienced musicians have plenty of reasons to take fresh talent under their wings, like gaining new bandmates with fresh skill sets, or helping future torch-bearers to thrive.
