Mitochondrial DNA copy number appears to be predictive of sudden cardiac death, heart attacks

Johns Hopkins researchers report that the level, or "copy number," of mitochondrial DNA--genetic information stored not in a cell's nucleus but in the body's energy-creating mitochondria--is a novel and distinct biomarker that is able to predict the risk of heart attacks and sudden cardiac deaths a decade or more before they happen.

Study uncovers how the brain reactivates networks of interrelated memories during sleep

A study led by the University of Barcelona has identified the process in the brain which strengthens or weakens memories of our daily events while we sleep. According to the study published in the scientific journal The Journal of Neuroscience , the brain reactivates networks of interrelated memories during sleep, instead of doing so with isolated memories.

MAIT cells could serve as new biomarkers for early detection, prevention of type 1 diabetes

Type 1 diabetes (T1D) is an autoimmune disease that develops when the immune system attacks beta cells in the pancreas. This destructive process is often attributed to autoreactive T lymphocytes. Yet the innate immune system, our body's first line of defense, also plays an important role in this disease.
