World's most powerful engine blazes path for space launch system advanced propulsion Posted: 26 Jan 2013 06:32 AM PST To help develop the nation's future heavy lift rocket, NASA resurrected the world's most powerful rocket engine ever flown -- the mighty F-1 that powered the Saturn V rocket-- and test fired its gas generator at the Marshall Space Flight Center in Huntsville, Ala.

Hubble finds appearances can be deceptive: Looking at the stars in NGC 411 Posted: 26 Jan 2013 06:29 AM PST Globular clusters are roughly spherical collections of extremely old stars, and around 150 of them are scattered around our galaxy. Hubble is one of the best telescopes for studying these, as its extremely high resolution lets astronomers see individual stars, even in the crowded core. The clusters all look very similar, and in Hubble's images it can be quite hard to tell them apart -- and they all look much like NGC 411. And yet appearances can be deceptive: NGC 411 is in fact not a globular cluster, and its stars are not old. It isn't even in the Milky Way.

Cows fed flaxseed produce more nutritious dairy products Posted: 26 Jan 2013 06:27 AM PST Dairy cows that are fed flaxseed produce more nutritious milk, with more omega-3 fatty acids and less saturated fat.

Daily antiseptic baths slash risk of bloodstream infections in critically ill children Posted: 26 Jan 2013 06:26 AM PST Daily baths with an ordinary antibacterial cleanser can safely reduce the risk of dangerous bloodstream infections in critically ill children, according to a trial conducted in five pediatric hospitals.

Potential benefits and threats of nanotechnology research Posted: 25 Jan 2013 12:48 PM PST A new article tackles the complex "dual-use" aspect of nanotechnology research.

Potential of differentiated iPS cells in cell therapy without immune rejection Posted: 25 Jan 2013 12:48 PM PST A new study shows that tissues derived from induced pluripotent stem (iPS) cells in an experimental model were not rejected when transplanted back into genetically identical recipients.

No more 'empty nest:' middle-aged adults face family pressure on both sides Posted: 25 Jan 2013 11:22 AM PST The "empty nest" of past generations, in which the kids are grown up and middle-aged adults have more time to themselves, has been replaced in the United States by a nest that's full – kids who can't leave, can't find a job and aging parents who need more help than ever before.

Nanohybrid with remarkable properties using a new laser-plasma process Posted: 25 Jan 2013 11:22 AM PST By achieving the synthesis of a novel nanohybrid structure by means of the pulsed laser ablation technique, experts have paved the way for a new generation of optoelectronic materials. The combination of carbon nanotubes and lead sulfide nanoparticles was performed using an effective and relatively simple process that offers considerable latitude for creating other nanohybrids for a variety of applications.

How to predict the future of technology? Posted: 25 Jan 2013 11:22 AM PST Forget Moore's Law. USC Marshall, Emory University and University of Michigan researchers define new ways to evaluate new technologies. The bread and butter of investing for Silicon Valley tech companies is stale. Instead, a new method of predicting the evolution of technology could save tech giants millions in research and development or developments of new products -- and help analysts and venture capitalists determine which companies are on the right track.

Research may lead to new strategies against sepsis Posted: 25 Jan 2013 11:22 AM PST Scientists are closer to solving a long-standing mystery in sepsis, a complex, often life-threatening condition. By blocking the activity of a protein in cells that line blood vessels in mice, they have halted a cascade of cellular events that culminates in out-of-control inflammation, and protected lungs from damage. The findings provide new insights into molecular details underlying sepsis and its effects on lungs, and may lead to new treatments.

New target for rheumatoid arthritis drugs Posted: 25 Jan 2013 11:20 AM PST Researchers have identified a potential new target for drugs to treat patients with rheumatoid arthritis. Efforts to develop drugs that hone in on this new target are underway.

Emotional stress reduces effectiveness of prostate cancer therapies in animal model Posted: 25 Jan 2013 11:20 AM PST Not surprisingly, a cancer diagnosis creates stress. And patients with prostate cancer show higher levels of anxiety compared to other cancer patients. A new study indicates that stress is not just an emotional side effect of the diagnosis; it also can reduce the effectiveness of prostate cancer drugs and accelerate the development of prostate cancer.

New tool for mining bacterial genome for novel drugs Posted: 25 Jan 2013 11:20 AM PST Biochemists have discovered that the process bacteria undergo when they become drug resistant can act as a powerful tool for drug discovery.
