A report about the robot was published in November in the journal Proceedings of the National Academy of Sciences.
SHIRLEY GRIFFITH: Increasingly, soft robots are being developed for difficult jobs like moving through a battlefield or wreckage from a natural disaster. The robot can move across uneven surfaces including small rocks and wet dirt.
Earlier this year, scientists from Tufts University in Massachusetts developed another kind of soft robot made of silicone rubber. This robot is about ten centimeters long and shaped like a caterpillar. It is able to roll up into a ball shape and move itself forward.
But researchers say there are difficulties in making these robots move. For one, they want to find a way for the robot to transport its own power source. They are also hoping to improve its speed.

STEVE EMBER: The World Health Organization says malaria was responsible for seven hundred eighty-one thousand deaths in two thousand nine. Most of those deaths were in children in Africa. Worldwide there were two hundred twenty-five million cases of the disease.
Both of these numbers represent improvements. In two thousand there were an estimated two hundred thirty-three million cases of malaria and almost a million deaths.
Malaria remains a major problem in Africa, but there have been some successes. Deaths in Rwanda, for example, have been reduced by sixty percent.
