                        Worms Get Ready to Fly in Space

   by Rosanne Skirble

   Humans are well-adapted to life on Earth. But when we move into space
   it's a different story. Low or zero gravity changes how the blood
   circulates, weakens the immune system, causes motion sickness, muscle
   loss and fatigue. Weightless can also trigger bone loss. VOA's Rosanne
   Skirble reports on a laboratory experiment with tiny, almost
   microscopic worms designed to help us better understand the impact
   long-term space travel will have on future astronauts
