NASA-sponsored studies have found that omega-3 fatty acids found in fish oil may play a role in mitigating bone loss that occurs during spaceflight, and in osteoporosis. Researchers say, the solution could have significant implications for space travelers and those susceptible to bone loss on Earth. Ongoing research has looked for ways to stop bone density loss in astronauts for decades. It\'s one of the main effects of exposure to the weightlessness of space. Researchers found that astronauts who ate more fish lost less bone mineral after four-to-six-month-long spaceflights. In a series of cell-based studies, scientists documented that adding a specific omega-3 fatty acid to cells would inhibit the activation of factors that lead to bone breakdown. The studies were conducted by a team of scientists across multiple disciplines at Johnson Space Center in Houston.

New White House guidance calls for agencies to submit data feeds to OMB\'s Cyberscope tool. Federal CIO Vivek Kundra hopes the information will give agencies a better idea of vulnerabilities and threats to computer networks. Agencies may have to shift money away from traditional reports to upgrade systems to meet new FISMA requirements.

NASA has successfully completed the first science flight of the Global Hawk unpiloted aircraft system over the Pacific Ocean. The flight was the first of five scheduled for this month\'s Global Hawk Pacific, or GloPac, mission to study atmospheric science over the Pacific and Arctic oceans. The Global Hawk is a robotic plane that can fly to altitudes above 60,000 feet, and as far as 11,000 nautical miles. Operators pre-program a flight path, then the plane flies itself for as long as 30 hours. GloPac researchers plan to directly measure and sample greenhouse gases, ozone-depleting substances, aerosols, and constituents of air quality in the upper troposphere and lower stratosphere. During its inaugural flight, the plane flew approximately 45-hundred nautical miles. The mission is a joint project with the National Oceanic and Atmospheric Administration.
