Editor's note

China just became the first country to land a probe on the far side of the moon – the side not visible to anyone on Earth. It’s an impressive technological achievement and another sign of China’s growing capabilities and ambitions in space. Political scientist Wendy Whitman Cobb explores whether our already tense relations with China could spur a new space race.

The euro turned 20 this month. For some, it’s a moment to celebrate the success of the largest monetary changeover in history. For others, it’s a reminder of just how much remains wrong about the common currency adopted by 12 European Union countries on New Year’s Day in 1999. Barry Eichengreen, an economist at the University of California at Berkeley, revisits the euro’s founding, where it went wrong and why it’s so hard to fix.

In a dramatic roll call vote yesterday, the Democratic majority re-elected California’s Nancy Pelosi as speaker of the House. Pelosi is the only woman in U.S. history who has held the powerful post. Political scientist Kathryn Pearson explains why Pelosi is a strong leader – even though she’s not popular with many.

The euro at 20: An enduring success but a fundamental failure

First elected in 1987, Pelosi offers decades of experience at building coalitions and she excels as a Democratic fundraiser. Still, the vote was closer than expected.

Today’s quote

“Today, the role of the speaker is influenced especially by changes instituted by Speaker Newt Gingrich, who took the gavel after the 1994 elections.”
