AP Poll: U.S. Tepid on Bush's Space Plans - Space.com  President Bush's plan to build a space station on the moon and eventually send astronauts to Mars hasn't grabbed the public's imagination, an Associated Press poll suggests. Asked whether they favored the United States expanding the space program the way Bush proposes, people were evenly split, with 48 percent favoring the idea and the same number opposing it, according to the poll conducted for the AP by Ipsos-Public Affairs 
Sunbathing Vitamin D pills cut MS risk   - BBC   Women who take vitamin D supplements are 40% less likely to develop multiple sclerosis, research suggests. The Harvard University team found eating a diet rich in vitamin D alone was not enough to provide the same protection. Nearly 190,000 women took part in the study, published in Neurology. Scientists formulated the theory that vitamin D plays a significant role in protecting against MS after data which suggested the condition was more common in countries furthest from the equator.    

Feeding The Martians - SpaceDaily  NASA-funded scientists are researching methods to address current issues and future needs for efficiently growing plants on Mars. The research data, featured on the cover of the January 2004 issue of the scientific journal Plant Physiology, focuses on using reduced pressure environments to increase the scientific and engineering benefits of plant growth experiments. The research is being conducted in the specialized low- pressure and Mars-simulation chambers. The data indicates, with the currently available materials on Mars, a greenhouse structure could only be constructed if the internal pressure of the greenhouse was maintained below approximately one-sixteenth of Earth's atmospheric pressure. Since extraterrestrial colonies and space vehicles may well employ reduced atmospheric pressures to lower the time and engineering costs of missions, we now have the beginnings of an understanding of how those atmospheres will impact our long-term life support system," said Robert Ferl, director, Space Agriculture Biotechnology Research and Education, University of Florida, Gainesville.
