Researchers at UCLA engineering discover theoretical model to predict jamming
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have come up with a theoretical model to predict when granular materials become jammed.

Study shows false memories complicate end-of-life treatment decisions
Advance directives, or living wills, may not effectively honor end-of-life wishes because life-sustaining treatment preferences often change without people being aware of the changes, according to a new study co-authored by UC-Irvine researchers Peter Ditto and Elizabeth Loftus.

Researchers important markers of high risk of type 2 diabetes
Researchers at the University of Warwick have found markers that indicate endothelial dysfunction (changes in the cells which line the blood vessels) and sub-clinical systemic inflammation can also help identify a far greater number of people at high risk for future development of type 2 diabetes.

Cancer immunotherapy shows long-term promise in lung cancer
New, long-term results from a clinical trial presented today at the 1st European Lung Cancer Conference jointly organized by the European Society for Medical Oncology and the International Association of the Study of Lung Cancer show that MAGE-A3 ASCI, an immune-boosting treatment for lung cancer patients, reduces the risk of relapse after surgery -- to the same extent as chemotherapy but without the side-effects of chemotherapy.

New genetic techniques to combat lung cancer
New results on genetic techniques that are helping doctors diagnose and treat lung cancer were released today at the 1st European Lung Cancer Conference jointly organized by the European Society for Medical Oncology and the International Association for the Study of Lung Cancer in Geneva, Switzerland.

Analysis shows combining sorafenib with carboplatin/paclitaxel adds no benefit in lung cancer
A clinical trial evaluating the benefit of adding the drug sorafenib to the combination of carboplatin/paclitaxel chemotherapy for lung cancer patients has been stopped based on results from an interim analysis, after an independent data monitoring committee concluded that the study would not meet its primary endpoint of improved overall survival.

Viruses may play a role in lung cancer development
Papers presented at the 1st European Lung Cancer Conference, jointly organized by the European Society for Medical Oncology and the International Association for the Study of Lung Cancer in Geneva, Switzerland highlight emerging evidence that common viruses may contribute to the development of lung cancer.

Minimally invasive pancreas surgery leads to fewer complications, study finds
When surgeons need to remove part of the pancreas, performing the operation with minimally invasive techniques offers patients a shorter hospital stay and fewer complications, researchers have concluded.

Opening a channel for salt retention
A research team has developed the first small molecule that can reversibly activate a key protein involved in balancing sodium levels, paving the way for drugs that can treat low blood pressure and related conditions.

Workers who reported increased work flexibility from one year to the next also had fewer absences for illness and improved job commitment, according to new research from Wake Forest University School of Medicine.

Anesthesia and Alzheimer's
In studies of human brain cells, the widely used anesthetic desflurane does not contribute to increased production of amyloid-beta protein; however, when combined with low oxygen conditions, it can produce more of this Alzheimer's associated protein.
