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.
Winds across the Illinois plains are now blowing clean, renewable energy into the Tennessee Valley Authority service region.
The Authority - a corporation owned by the U.S. Government - has begun transmitting 300 megawatts of renewable wind power to its customers received from Iberdrola Renewables' Streator Cayuga Ridge wind park in Livingston County, Illinois.
It marks the first delivery under seven contracts TVA recently signed to purchase up to 1,380 megawatts of renewable wind energy from the Midwest. It's the largest of the TVA's wind-power contracts, which altogether may provide enough electricity for about 325,000 homes in their seven-state service region.
Senior vice president for the Tennesee Valley Authority John Trawick says the new wind-power source is an important milestone in the Authority's plans to expand their clean and renewable energy options.
U.S. Citizenship and Immigration Services has redesigned the Permanent Resident Card - commonly known as the "Green Card" - to incorporate several major new security features.
They've begun issuing all Green Cards in the new format. The redesign is the latest advance in the Immigration Department's ongoing efforts to deter immigration fraud, that officials say will better serve law enforcement, employers, and immigrants.
Among the benefits of the new technology: Secure optical media will store biometrics for rapid, reliable identification of the card holder. Holographic images, laser engraved fingerprints, and high resolution micro-images will make the card nearly impossible to reproduce. Additionally, Radio Frequency Identification capabilities will allow Customs officers at ports of entry to read the card from a distance and compare it immediately to file data.
Many say for the government to secure their own networks, it must work more closely with the private sector.
The Homeland Security Department, and other agencies, are now testing out just how that approach might work. That Department is in the middle of several pilot programs to improve how the government and industry share information related to cyber threats.
One goal is to make the sharing of classified information easier, such as an expansion of the post-9/11 Network Fusion Centers used in every state.
Cyber criminals know how to steal online funds, but the criminals who know how to convert those funds into cash are now being targeted specifically by the FBI.
Agency officials say they're targeting - what they call - the "money mules" who receive the transfers of stolen funds into their bank accounts. They then make the transaction appear legitimate, sending the money to associates in other countries.
The FBI hopes to raise public awareness and dissuade people from becoming mules. The FBI hopes to raise public awareness and dissuade people from becoming mules.
"Mobile workdays" are telework's sexy side. The truth of the matter is the day to day telework grind has benefits too.
The "Tools for Online Success" site features tutorials, video testimonials, and tips from savvy small business people who have leveraged the web to become more efficient, more cost-effective, and more successful. Joe Zepecki, deputy assistant administrator for communications at the SBA explains.
