A new brain imaging test can detect a key hallmark of Alzheimer’s disease before symptoms appear and earlier than the method currently used in clinical practice in the United States and Europe, report University of Pittsburgh School of Medicine researchers in The Lancet.

Researchers at the University Medical Center Göttingen (UMG) and the University Hospital of Schleswig-Holstein (UKSH) have made a significant breakthrough in the treatment of severe heart failure: For the first time, a clinical trial has demonstrated that laboratory-grown heart muscle tissue can improve the pumping function of damaged hearts.

Scientists have developed a powerful new technique that allows them to observe how individual cells manufacture proteins during aging, offering an unprecedented glimpse into the hidden molecular activity of stem cells in living tissue.

Brain tumor growth may depend not only on cancer-causing mutations, but also on the molecular conditions in specific brain regions.
