In this video excerpt from NOVA scienceNOW, learn about the potential energy contained in food. Correspondent and technology columnist David Pogue explores how a rat is digested by a snake and how food fuels the body. Scientist Stephen Secor demonstrates how to measure the amount of energy stored in a food using a bomb calorimeter. Portions of a dehydrated cupcake and rat are burned in a special tank; the results show that the cupcake has twice as many calories as the same amount of rat.

If two dogs are asked to do a trick and only one of them gets rewarded, the unrewarded dog soon stops cooperating. This experiment, along with investigations of other animal species, can provide insight into the evolution of human morality.

People from the Mbuke and Whal islands discuss the impacts climate change is having on their communities and the steps they are taking to adapt in these three videos from The Nature Conservancy. In "Pacific Islands Benefit from Climate Change Adaptations", islanders store foods in case of drought and learn to grow alternative crops. In "Fishing Bans", a ban on net fishing close to shore will hopefully protect fish populations. In "Mangroves", a replanting program will hopefully help save the coastline from erosion and bring back fish and mud crabs. Note: This video includes native languages and is subtitled in English.
