A side effect of these chemical reactions is a lot of heat. The fact that the chemical reactions in a fire generate a lot of new heat is what sustains the fire. Many fuels burn in one step. Gasoline is a good example. Heat vaporizes gasoline and it all burns as a volatile gas. There is no char. Humans have also learned how to meter out the fuel and control a fire.
Researchers just mapped their genome for the first time to find out. By Paca Thomas. Bowhead whales can live more than 200 years, and they rarely succumb to cancer or disease. Searching for clues about their longevity, researchers just mapped their entire genome. Watch more in the video above.
Blue whales are the largest animals ever to have lived-they dwarf even the largest of the dinosaurs. Living in the the open ocean, they are found usually found along the continental shelf edges and near polar ice.
