Russian research team explores vision complications for astronauts

An international partnership between Florida State University and a team from the Russian Academy of Sciences has found that space travel may severely impair the body's ability to regulate blood rushing to the brain, which could contribute to the temporary or permanent vision problems experienced by astronauts.

In a new paper published in the Journal of Applied Physiology, Florida State Professor Michael Delp and Russian colleagues Olga Tarasova and Olga Vinogradova delve into the complications that occur when humans travel to space and spend weeks to months in a weightless environment.

In recent years, NASA has become interested in investigating vision problems observed in astronauts returning from space. On shorter trips, astronauts have often experienced minor vision changes that eventually self-correct. But longer visits to space have caused more substantial issues.

"What has happened is we've become much more aware of medical problems humans can face when staying in space for extended periods of time," said Delp, who also serves as dean of the College of Human Sciences. "Astronauts are willing to make sacrifices of their body in order to go into space, but few are willing to compromise their vision."

For NASA, the issue is a top research priority, and a number of scientists around the world are working to solve the problem. Delp, a physiologist who studies the effects of microgravity on the cardiovascular system, began working on the issue of what happens to the body when people travel to space several years ago. To further the work, he and a group of researchers at the Russian Academy of Sciences who were studying similar issues formed a partnership.

The Russian Federal Space Agency, with the help of NASA, assembled an international team of researchers to study mice sent into space for 30 days on a Russian satellite, the Bion-M1.

When the satellite returned to Earth, the mice were whisked by ambulance to laboratories at the Institute for Biomedical Problems in Moscow, where the research team hunkered down for hours, investigating arteries that control blood flow to muscle, skin and the brain of the small creatures.

They soon discovered that the brain held the most interesting responses to the spaceflight.

"Without gravity pulling body fluids down toward the feet, fluid will rise toward the brain," Delp said. "When spaceflight alters the function of arteries that precisely regulate blood flow to the brain, it could severely affect many things, including vision."

The issue remains how to solve that problem.

Delp and his Russian colleagues are already setting the stage for future experiments that may yield more answers and possible solutions. In May, another group of mice will be sent to the International Space Station for observation.

"It's truly been a remarkable collaboration," Delp said. "The Russian scientists are unbelievable partners."

Moon momentos found languishing in Armstrong's closet
Washington (AFP) Feb 10, 2015
A treasure trove of prized momentos from the first moon landing have been found in Neil Armstrong's closet by his wife when she was doing a clearout. Armstrong, the first man to walk on the moon, died in August 2012 and his wife Carol found the objects from the 1969 lunar expedition languishing at their home in Cincinnati, Ohio. The objects include a 16mm camera that was mounted on the w ... read more
