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.
