Scientists uncover how a cell's 'fuel gauge' promotes healthy development

27-Apr-2016

Salk scientists have revealed how a cellular "fuel gauge" responsible for monitoring and managing cells' energy processes also has an unexpected role in development. This critical link could help researchers better understand cancer and diabetes pathways. This cellular fuel gauge is a protein ...

Scientists identify genes that control smooth muscle contraction

26-Apr-2016

Researchers at UMass Medical School have identified a new molecular pathway critical for maintaining the smooth muscle tone that allows the passage of materials through the digestive system. This finding, based on studying calcium ion-controlled pathways in mice, may lead to new treatments for a ...

New technique could improve detection of concealed nuclear materials

19-Apr-2016

Researchers have demonstrated proof of concept for a novel low-energy nuclear reaction imaging technique designed to detect the presence of "special nuclear materials" -- weapons-grade uranium and plutonium -- in cargo containers arriving at U.S. ports. The method relies on a combination of ...

Life-preserver microbubbles float tumor cells for analysis

19-Apr-2016

A University of Colorado Cancer Center study presented at the American Association for Cancer Research Annual Meeting 2016 demonstrates the use of gas microbubbles to selectively attach to and float circulating tumor cells from blood samples, allowing analysis of the isolated cells. "Microbubbles ...

In wide range of species, longevity proteins affect dozens of the same genes

15-Apr-2016

Whether a creature is a worm, a fly, a mouse, or a human, death inevitably awaits. And not only do these organisms share a common fate, but also, according to a new study, they may share some of the specific mechanisms of mortality. The researchers found that in all four species, there are 46 ...

Neuronal structures associated with memory sprout in response to novel molecules

Drug candidates protect neurons against damage from substance implicated in Alzheimer's disease

12-Apr-2016

Chemists at the University of California San Diego have designed a set of molecules that promote microscopic, anatomical changes in neurons associated with the formation and retention of memories. These drug candidates also prevent deterioration of the same neuronal structures in the presence of ...

New predictive tool for assessing breast cancer risk

Levels of molecular marker Ki67 in healthy breast tissue predicts a woman's risk of developing breast cancer

11-Apr-2016

Harvard Stem Cell Institute (HSCI) researchers at Dana-Farber Cancer Institute (DFCI) and collaborators at Brigham and Women's Hospital (BWH) have identified a molecular marker in normal breast tissue that can predict a woman's risk for developing breast cancer, the leading cause of death in ...
