Older adults that improved their fitness through a moderate intensity exercise program increased the thickness of their brain's cortex, the outer layer of the brain that typically atrophies with Alzheimer's disease, according to a new study. These effects were found in both healthy older adults and…

Both in materials science and in biomedical research it is important to be able to view minute nanostructures. Scientists have developed a new computed tomography method based on scattering of X-rays. With this technique they can visualize nanostructures in objects measuring just a few millimeters,…

High blood cholesterol is linked to an increased risk of heart disease and stroke. To identify new strategies to combat high cholesterol in genetically predisposed individuals, new preclinical models that mimic the underlying pathophysiology are needed. Researchers have now shown that cells derived…

A new technique called metabolite profiling has been used by scientists to identify a biochemical pathway previously unknown to be regulated by aspirin. Specifically, the researchers found that aspirin substantially decreases the level of a chemical called 2-hydroxyglutarate in the blood of healthy…
