The Littlest Astronauts

WHY STUDY BUGS IN US . . . IN SPACE?

Just getting into space is an ordeal. It starts with the acceleration and jarring vibration of a rocket launch. Minutes later, astronauts float weightlessly about 250 miles (400 km) above the Earth’s surface in low Earth orbit. Once in space, every minute is scheduled. The constant demands on their attention can stress out astronauts. Their living space is cramped and not at all private. And they are stuck with the same crew for months. Also, the air smells weird. Stress changes body functions and invites illness. Lots of time and money go into selecting and training astronauts, so protecting their health is important to NASA. The last thing anyone wants is for an astronaut to get sick in space.

Scientists Create Mice With Woolly Mammoth-Like Fur
RESEARCHERS AT A COMPANY IN TEXAS ARE WORKING TO CREATE A LIVING ANIMAL THAT RESEMBLES THE EXTINCT WOOLLY MAMMOTH. Recently, they produced mice with traits of the large mammal. The mice all have coats with mammoth-like fur, and some of the small mammals also have genes that help them store fat. Both features would help the animals survive in the cold Arctic, where the woolly mammoth once lived.
