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.

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.

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.

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.
