Stat: 80,000. Chilean Patagonia has more than 80,000 kilometers of coastline, the longest in the world. Story: In the latest installment of our "Scientists at Work" series, Pew marine fellow Vreni Häussermann talks about Chilean Patagonia's diverse ecosystem. The region is a near-pristine wilderness like no other—but this mostly unexplored wilderness is at risk. Häussermann hopes her research will help support efforts to secure a sustainable future for Chilean Patagonia and the marine life in its fjords.

Stat: 96 percent. Nearly all of America's hospitals used electronic health records as of 2017, according to the U.S. Department of Health and Human Services.

Stat: 18. At least 18 British colonies existed in North America during the American Revolution—but, as we know, only 13 signed the Declaration of Independence.

Temple University history professor Jessica Roney shares insights about America's Founding Fathers and illuminates the lesser-known history behind the formation of the United States.

Mangrove forests are natural protectors, shielding coasts from storms, sheltering species, and soaking up carbon. Reversing the decline of these habitats isn't just a science—it's an art, says marine biologist Octavio Aburto. He uses his camera along with high-resolution satellite imagery to assess real-time changes in mangrove coverage—and to reveal the amazing hidden marine life of these critical ecosystems.

Stat: 93. The Food and Agriculture Organization of the U.N. estimates 93 percent of marine fisheries worldwide are fished at or beyond sustainable catch levels. Story: A large part of overfishing is driven by subsidies—most of which go to large-scale fishing fleets from industrialized nations. We learn about how subsidies can alter the economics of fishing from Pew's Isabel Jarrett and researcher Rashid Sumaila. And we travel to Senegal to hear from local fishers on the impact to their communities.

Stat: 46. The percentage of American adults who worry that they will not be able to live comfortably in retirement.

Hear why in the final episode of our series on the American family, which features two retirees' stories, and expert analysis from John Scott, who directs retirement savings work at Pew.

Story: From diapers to day care and beyond, it's getting more expensive to raise a family in the U.S. And just keeping up with daily costs makes saving for a rainy day or retirement all the harder. We speak with three families about what it takes to make it work—and what keeps them up at night.
