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.

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
