Keeping mold out of future space stations

Mold can survive the harshest of environments, so to stop harmful spores from growing on future space stations, a new study suggests a novel way to prevent its spread.
Antarctic research supports healthy space for astronauts

Astronauts and Australian Antarctic expeditioners are working together to advance human health in space, and on Earth.
Today, four astronauts are orbiting Earth on the Polaris Dawn mission, undertaking a range of research projects to better understand the effects of long-duration spaceflight on human health.
At the same time, expeditioners and doctors at Australia's Antarctic and sub-Antarctic stations are collecting data for two of the projects, involving ultrasound and body scanning technology.
Australian Antarctic Division Chief Medical Officer, Dr. Jeff Ayton, said the two projects were part of a collaboration with the US-based Translational Research Institute for Space Health (TRISH).
"Antarctic expeditioners and astronauts are both isolated, confined populations in extreme environments, doing hazardous work, dependent on technology for survival, and with limited scope for evacuation," he said.
"This makes Australia's Antarctic Program an excellent analog for understanding the risks to humans in space, and for testing and developing technologies and methodologies to reduce these risks.
Polaris Dawn project aims to prevent bone loss in space

Dartmouth researchers have a project aboard the Polaris Dawn mission they hope will help address two major health risks of space flight—the breakdown of astronauts' bones in zero-gravity conditions and the resulting danger of developing kidney stones.
When subjected to weightlessness, bones freed from the burden of supporting the human body leach calcium. The shedding of this critical element reduces bone density and, as the calcium enters the urine, heightens the chance of painful kidney stones forming in the urinary tract.
Through Polaris Dawn, which launched from Florida on Sept. 10, researchers at Dartmouth's Geisel School of Medicine and Thayer School of Engineering are testing a critical element of a handheld device the team is developing that would alert crew members to high levels of calcium in their urine during space flight so they can take action.
