The United Nations set an ambitious goal of ending extreme poverty and fighting disease by 2030. But a lot of governments and international organizations and researchers still aren't collecting basic statistics. For example, currently over 150 million kids in poor countries have stunted growth, largely due to malnutrition, but there isn’t data about which nutrients available in these countries are most needed to prevent malnutrition. The data gap is especially noticeable when it comes to statistics on girls and women. This makes it hard to prioritize health spending. Listen to this story and debate what can be done to improve data on poverty.

The search for food that is low cost, tasty and slow-to-spoil has been an ongoing goal of the military, especially during World War II. That’s why military science has influenced the food in school lunches, as well as other convenient foods such as granola bars and juice boxes. Military research and ingredients are found in many foods, including the McDonald’s McRib Sandwich. A new book encourages people to think more about where convenient, non-perishable food comes from and whether this food science should be used so commonly outside the military.

The book "Into the Wild" chronicled the journey of twenty-four year old Christopher McCandless who died in April of 1992 after attempting to survive alone and virtually unaided on a remote Alaskan hiking trail. While McCandless’ official cause of death has been recorded as starvation, author Jon Krakauer has evidence suggesting otherwise. Krakauer, who wrote "Into the Wild," has conducted extensive research on McCandless’ death even after he first published the book chronicling McCandless’ experiences. His findings have led him to believe that McCandless’ death may have been caused by the ingestion of a poisonous potato seed that is only deadly if you are malnourished. Listen to hear what evidence led Krakauer to this conclusion.
