Grasshoppers have to deal with blood pressure issues when they are upside down. By James Gorman You wouldn’t think gravity would be a big worry for insects. They’re so small. So light. An ant ...

Researchers at UC-San Diego have engineered a negative-pressure gravity suit that could slow or even prevent the ravages of microgravity on astronauts' bodies suffered during extended spaceflight.

"We can learn more about the role gravity plays on fluid around the brain, for instance," she said. "And it gives us insight into how disorders of cerebrospinal fluid circulation affect patients ...
