After working for years in the pharmaceutical industry, Joseph Dominguez enjoyed the freedom to take on scientific research he found in an academic institution that had no commercial ties

Scientists have uncovered a key reason why exercise is so effective at helping older muscles stay strong. A new study from Duke-NUS Medical School shows that physical activity can restore the natural repair systems that weaken with age, helping muscles recover and maintain function later in life

Scientists have identified evidence of a previously unknown process that may explain how brain cells die in Alzheimer’s disease and frontotemporal dementia (FTD). The discovery, centered on a mechanism known as karyoptosis, could point researchers toward new ways to slow the progression of these devastating conditions
