A new study has found that astronauts' eyeballs have become deformed after spending a long time in space. The researchers said that flattening at the back of the astronauts' eyes may be caused by increased pressure of cerebrospinal fluid in microgravity. Doctors examined 27 astronauts who had flown long-duration missions with NASA and found a pattern of deformities in their eyeballs, optical nerves and pituitary glands that remains unexplained. The problems are similar to those...

Image 1 - Astronaut Vision Changes Offer Opportunity For Research

Astronauts on the International Space Station are not allowing vision issues to keep them from completing their important tasks on the orbiting laboratory. In fact, they are taking advantage of the opportunity to study why weightlessness alters vision. Even after 50 years of human spaceflight, scientists still are making new discoveries about human health in microgravity. New research points to a permanent vision risk for astronauts living without gravity. A large part of the International...

Louisiana Tech, NASA Partner On Zero-gravity Experiments

  Researchers from Louisiana Tech University will be floating high above the Gulf of Mexico this month to conduct zero-gravity testing of an experimental DNA analysis instrument developed at Tech that could benefit future NASA astronauts. Dr. Niel Crews, assistant professor of mechanical engineering, and Collin Tranter, a graduate student with the Institute for Micromanufacturing (IfM) say the instrument could be used to monitor the health of astronauts exposed to cosmic radiation...

NASA-sponsored studies have found that omega-3 fatty acids found in fish oil may play a role in mitigating bone breakdown that occurs during spaceflight and in osteoporosis. Ongoing research for decades has looked for ways to stop bone density loss in astronauts. The solution could have significant implications for space travelers and those susceptible to bone loss on Earth. The studies' results are published in the May issue of the Journal of Bone and Mineral Research. The paper reports on...
