Time in space may stretch worm lifespan

Scientists studying loss of bone and muscle mass among astronauts find that spaceflight’s effects on microscopic worms may help them live longer.

In addition, they report that a group of genes are expressed at lower levels during spaceflight. When the expression of these same genes was lowered in the worms back on Earth, they lived longer.
