If you want to try guessing the answer, stop reading now.

Have you guessed? OK, start reading again.

According to a new study, a zebra’s stripes most likely help to keep annoying, biting flies off them.

Scientists have thought that might be the reason.

However, they also had other theories: that the stripes provide camouflage to help them hide from enemies; to confuse their enemies; to help them stay cool; or for a social reason such as to attract a mate.

Zebra Dung May Be New Fuel Source

Thanks to zebra dung, cars could one day run on fuel made from old newspapers.

Today, we use mostly oil and gas to run our cars; oil and gas come from fossilized plants and animals. But fossil fuels are expensive, and there aren’t enough of them. Scientists are looking for cheaper and more plentiful fuels.

David Mullin is a biology professor at a university in New Orleans. He and his students are trying to make a fuel from plants. Plant-based fuels are called “biofuels.”

He knew that if he could break down “cellulose,” he could turn it into a fuel that could run vehicles.
