Stat: 61 percent. That's how many voters say they're enthusiastic about voting in November. Story: Traditionally, voters don't flock to the polls for the midterm elections. But this year, the Pew Research Center has found that voters are more enthusiastic about voting than at any point during midterms in the past two decades. Why is that and what's on voters' minds? In this episode, Dan LeDuc talks with the center's director of political research, Carroll Doherty, who will share his insights from the polling data.

Stat: 7 out of 10 babies born in London have at least one parent who wasn't. Story: London is on track to exceed 9 million people in three years and most of the new babies there have at least one foreign-born parent. One area in particular is emblematic of these changing world demographics: Brixton. Host Dan LeDuc went for a walk there with Ben Rogers and Denean Rowe from the Centre for London to see up close how it's evolving from a quintessential South London neighborhood into a dense, multicultural hub.

Stat: 70 percent. That's how many children now born in London have at least one foreign-born parent.

Ramsey shares his thoughts about why so many Americans are in debt today, why they're not stuck, and the key to breaking the cycle.

Stat: Four. That's how many letters in the DNA alphabet make up every living thing.

Story: How does genetic information transmit across generations? While trying to find out, scientists Craig Mello and Andrew Fire quite by accident made a discovery in 1998 that would earn them a Nobel Prize—and pave the way for the first drug to take on harmful genes. Pew's Dan LeDuc talks with Mello about science's surprises.

Stat: North Atlantic cod have nearly tripled since 2006 to 118,000 tons. Summary: Overfishing has strained most global fish stocks. But the European Union has made progress bringing back one popular species: North Atlantic cod. The flaky white fish—a British staple when battered and served with chips—has rebounded after plummeting to critically low levels in the late 2000s. In this episode, we go to one of London's oldest fish and chips restaurants and learn how quotas can be used to help other stocks recover.

Stat: 44 percent. The percentage of Americans who think the public doesn't know enough about science to understand new findings in the news. Story: Ira Flatow, the host of "Science Friday," has been with National Public Radio since it went on the air in 1970. Although he knows the public loves science, he's worried that most people don't know how the scientific process works. Pew's Dan LeDuc talks to him about why critical thinking is crucial, who asks the best questions, and how science can be addictive.

Stat: At least 2 million Americans get antibiotic-resistant infections each year. Story: Nearly a century after Alexander Fleming's discovery of penicillin, bacteria continue to develop the ability to defeat antibiotics. Doctors worldwide are concerned about the spread of superbugs that are resistant to all antibiotics. Host Dan LeDuc visits Fleming's London lab for some history and talks with Pew's Allan Coukell about current efforts to reduce unnecessary use of these drugs and encourage development of new ones.

Stat: $477 billion. That's the amount spent on prescription drugs in the United States last year, according to the Department of Health and Human Services.

In this rebroadcast of a Pew event, she discusses what can be done to manage drug costs and ensure that Americans get the medicine they need.

Stat: At least 63 million sharks are taken from the ocean every year. Story: And that's the low estimate; others range as high was 273 million. That worldwide catch—for shark fins and increasingly for their meat—is threatening some species with extinction. In this episode, host Dan LeDuc talks with two unlikely advocates for protecting sharks: South African Paralympian Achmat Hassiem and Pew's Debbie Salamone. Both have been bitten by sharks but have turned their experiences into something positive: becoming shark attack survivors supporting shark conservation.
